3.1.3 Live Image Capturing/Focusing
Click the “Video” button.
Highlight the icon of the camera you want to see. Click the
“Full Size” and “Live” video buttons. You will now see a live
video image. The live image is generated by an internal
trigger mechanism inside the EN camera. This internal trigger
is independent of either FTP or message-based TCP image.
Also, during live image display, Flash is disabled at nighttime.
The “Snap” button captures only a single video image. The “Freeze” button disables the “Live”
image option.
Use the “Live” or “Snap” buttons only while the camera is being set up, for those occasions you
want to see the maximum frame rate of the video image to focus the lens.

Click the “Quad Size” image button to capture four images. Each image will then be reduced from
the full resolution to one-quarter resolution. Click and drag the camera icon to the desired quad
image frame. Click the “Live” button to see a live image.
Note: Because Bayer Color information is sub-sampled and lost, color cameras do not display proper
color in “Quad Mode”.
Three trigger-sniffing modes are available: “One,” “All,” and “Last.” “One” trigger mode is for
when you want the EN camera to take a single shot of video image, as soon as it receives a valid TTL
trigger, Ethernet trigger, or RS-485 serial trigger. “All” trigger mode is continuous trigger-sniffing
mode. Trigger sniffing is a mode of operation that allows the user to continuously and passively
monitor images captured by the external trigger without disturbing the trigger process. For every
trigger input, the EN camera will capture a new image. “Last” trigger mode is the same as “All”
trigger mode, except that the EN camera will send the last captured image when you select the
“All” button. Flash is activated when the trigger is received.
Figure 10. Hardware Trigger Sniffing Mode
The “HW Trigger” and “Rep. Trigger” buttons send the Ethernet trigger command to the EN camera.
“HW Trigger” button sends a single Ethernet trigger command. “Rep. Trigger” sends a continuous
Ethernet trigger command every second

3.2 Image Transfer
3.2.1 FTP Image Transfer
To transfer images via FTP, first make sure to set up the FTP server properly. Please check the
following items:
The username/password or anonymous login must be set for FTP server.
Set the permission of the read/write/create directory.
First, type the IP address of the FTP server (destination IP). If you have a second FTP server, enter
that IP address as well. If the EN camera detects that the first FTP server is down, then it will
automatically send images to the second FTP server.
Enter the User name and Password that the FTP server gives permission to.
Type image type (TIF or JPEG). “Image1 Data” is an image triggered by the first TTL trigger,
Ethernet trigger, or RS-485 serial trigger. If the second FPGA trigger is set (Config Address=28), then
the FPGA automatically generates the second hardware trigger predefined delay after the first
hardware TTL trigger. “Image 2 Data” defines image type of the second triggered image. Normally,
you should ignore the “Image 2 Data.”
“Subdirectories” is normally set to 1000. The EN creates subdirectories under a single Destination
DIR. When the number of files in the subdirectory reaches 1000, then the EN automatically creates
another subdirectory. Naming conventions of the subdirectory can be found in the LC-to-EN
interface document.
“Destination DIR” is a name of the directory where all “Subdirectories” are located.
Please refer to Troubleshooting “Problem 9: FTP servers switch between primary server and second
server, even if the hard disk is not full.” on page 42.
3.3 ADR (Automatic Dynamic Range) Control
3.3.1 Light Sensor Connection
ADR control is a process that runs inside the EN camera. It controls the camera every 1/10 second to
ensure that when the camera is triggered, it produces a high quality image of the license plate and

on/off auxiliary lighting as required to maintain proper plate illumination at night and during
dawn/dusk transitions. ADR uses an external light sensor to provide the information required to

operate properly. ADR operation can be enabled/disabled by the user at any time. Make sure to set
up Moxa (RS-485 to Ethernet converter) properly. See (VIS400 manual Appendix A).
In the camera’s “Properties” window, set up the light sensor’s IP address and Port number. These
numbers must be consistent with Moxa’s setting.
You can connect up to two light sensors. If two IP addresses and port numbers are identical, then
the EN camera tries to connect only a single light sensor.
Set the ADR Control register from “Manual” to “ADR Control (Using the Light Sensor).” This will
activate the connection to the light sensor. If the connection is successful, you should see a live
data change in the ADR Debug side A/B registers. Also, you should see what camera parameters ADR
decides to set. In the above example, ADR sets to exposure time 4H (Dial 4 = 4H), Gain=255(max),
Vtop=0, and Vbot=0. If there is a connection error, then these register values will all remain zero.

Also, check the “Error Status” register. If there is a connection error, LS1_ERR or LS2_ERR is set. If a
light sensor is not required for your application, set the “Camera ADR Control” register to “Manual.”
3.3.2 Flash Nighttime Light Control
The strobe and continuous nighttime light can be manually turned on and off. Set “Flash
Auto/Manual” and “Night light Control” registers to Manual OFF or ON.
Generate an Ethernet trigger or input TTL trigger to see Flash. The “Live” or “Snap” button does
not generate Flash, because they are independent from normal trigger operation.
Normally, Flash and Night Light are controlled by ADR and a light sensor. To take advantage of this
feature, connect to the light sensor. Set the “Flash Auto/Manual” and “Night Light Control”
registers as shown below.
In this setting, in the evening when light sensor reading drops below 12, Flash and Night Light are
turned on. And in the morning when the light sensor reading rises above 17, Flash and Night Light
are turned off.

3.4 Time Synchronization
The EN camera supports NTP (network time protocol) synchronization. If you disable NTP by clearing
the “NTP Client Control” register, then the internal clock will drift approximately 1.5 seconds per
day.
To reset the clock, set the “Real Time Clock” register to your current local time.
If you decide to take advantage of the NTP feature, make sure to set up the NTP server, preferably
with GPS input. This guarantees that the clock drift is within 10ms. Set the NTP server IP-address
registers up to 3 NTP servers. Then, enable “NTP Client Control” register. Reboot the camera.
After rebooting the camera, check the “Real Time Clock” register to check if the current time is
properly set. Note that this time is GMT.
If the NTP drift file is empty, then the NTP will take about 1 hour to optimize the time. During the
initialization, “NTP Status” must show USYNC, and “NTP estimated error” is max. After 3-4 hours,
the time drift will become within 10ms. Check “NTP estimated error” and “NTP Status” registers
again. “NTP Status” must be showing “PLL.” This means that NTP is finally synchronized properly.
3.5 Static IP Address Assignment
The factory default IP assignment is static IP= 10.0.0.65. The user must change the IP address of the
camera. There are four methods to change the static IP address: EN setup software, Telnet, serial
terminal using the debug RS-232 serial/power cable, and BIOS/Monitor using the debug RS-232
serial/ power cable.

EN Camera Series
The first two options, EN setup software, and Telnet, require that the network settings of the EN
camera such as IP address and Subnet Mask be known, while the last two options do not. If Ethernet
is not available, then the last two options will be useful.
The EN setup software is the easiest way to change IP address. In the “Properties” window, change
the network setting registers. After changing these registers, reboot the camera. The new setting
appears at the next power-up.
•
•
•
Telnet
If you know the current IP address of the camera, you can telnet directly to the EN camera.
Login as User name = root, Password = JAI PULNiX. If you want to assign a new IP address
temporarily, you can use the “ifconfig” utility. If you want to assign a new IP address
permanently, you can use the “test_libcamera” utility (See Section 3.6.3, “RS-232 PowerPC
Debug Port,” on page 18).
Serial terminal using the debug RS-232 serial/power cable. This is exactly the same as the
previous “Telnet” solution, except that you do not need an Ethernet connection. If Ethernet is
down, or if the IP of the camera is unknown, this method is useful. You can use “ifconfig” or
“test_libcamera” utility to assign new IP address temporarily or permanently
(See Section 3.6.3, “RS-232 PowerPC Debug Port,” on page 18).
BIOS/monitor using Debug RS-232 Serial/Power cable. The BIOS/monitor is an even lower level
of software running underneath of OS and application code. By using the BIOS/monitor, you can
assign a new IP address permanently. See Section 3.6.3, “RS-232 PowerPC Debug Port,” on page
18 for detailed operation.
3.5.1 DHCP Client
Make sure that you have a DHCP server in your network.
Change the “Static/Dynamic IP Address Allocation” register from “Static” to “Dynamic.”
Reboot the camera. In the next power-up, the camera will get the IP address dynamically from the
DHCP server.

3.6 Maintenance
3.6.1 Debug Counters
For debugging purposes, some status registers are available as debug counters.
Detailed information for each debugging counter is included in the LC-EN Interface document. This
tutorial covers the following debug counters.
•
•
•
•
Trigger Filter Noise count = number of hardware TTL triggers that failed trigger noise filter.
PRE Filter Noise count = number of hardware TTL triggers that failed PRE filter.
POST Filter Noise count = number of hardware TTL triggers that failed POST filter.
Valid Trigger count = number of hardware TTL triggers that passed noise filter, PRE filter, and
POST filter.
•
•
VINIT count = number of reset signals sent to CCD
IRQ count = number of interrupt generated by FPGA to PowerPC
By generating an Ethernet trigger (“All” and “HW Trigger” button on the EN setup video window),
you can see only VINIT and IRQ counters are incrementing. This is because the first four counters are
only for the hardware TTL trigger.
By feeding the hardware TTL trigger, you can see “Valid Trigger count,” “VINIT count” and “IRQ
count” register incrementing.
If you set 1ms to “Trigger Filter Noise” register and the hardware TTL trigger pulse is less than 1ms,
then the trigger is ignored as an invalid signal. Only “Trigger Filter Noise count” must be
incremented. However, all other counters remain the same.

EN Camera Series
If you set the PRE trigger filter to 10ms but the TTL trigger has only 9ms stable PRE condition, then
only “PRE Filter Noise count” must be incremented. However, all other counters remain the same.
If you set the POST trigger filter to 10ms but the TTL trigger has only 9ms stable POST condition,
then the “POST Filter Noise count” must be incremented. Unlike PRE trigger, “VINIT count” is also
incremented, because trigger pulse is sent to CCD anyway before finishing validation of POST
condition. Once FPGA invalidates the POST condition, FPGA does not generate IRQ to PowerPC.
Besides “POST Filter Noise count” and “VINIT count,” all other counters remain the same.
3.6.2 Firmware Upgrade
In the “Properties” window, right-click on the camera icon you want to upgrade. Select “Update
Firmware in Camera(s).”
You can update the five pieces of firmware inside the EN camera. Each piece of firmware has a
distinctive extension.

3.6.3 RS-232 PowerPC Debug Port
If you have the debug RS-232 serial/power cable, you can debug EN cameras over the serial port.
This is useful when Ethernet is not available. In this tutorial, we suppose we have accidentally
assigned an invalid IP address to the EN camera, and now we cannot communicate with the EN
camera over Ethernet. When this happens, there are two recovery methods.
The first method requires setting the Hyper terminal to the following setting (9600-8-N-1. No
hardware handshake).
Power up the EN camera. You should see the monitor message in the serial terminal. Type the “/”
key within three seconds.

Enter the command “ps” to see what processes are running. If the “dhcpc” daemon is running, kill
this process. To do so, enter, for example, “kill <process_id>.”
Enter the command “ifconfig” to see if the network is up and running.
Eth0 is the network interface of the EN camera. In the above example, the EN’s network is set to
the following: IP address = 10.0.0.65. Subnet mask = 255.255.255.0.
If eth0 is not running or if you want to change to a different IP address, you can set the temporary
network setting just to enable a FTP, TELNET, or Ethernet connection
Enter the command “ifconfig eth0 <NEW IP ADDRESS> netmask <SUBNET MASK>.” This is a temporary
IP assignment because the EN camera will lose this setting once you restart it.
Now you should be able to telnet to the EN cameras.
If you want to assign the new IP address permanently, you can use the “test_libcamera” utility. The
“test_libcamera” utility allows access to EEPROM, where all network settings are saved. After
starting “test_libcamera,” you can use the following commands:
rc : read IP assignment (static or dhcp)
rp : read IP address
wc : write IP assignment
wp : write IP address
ws : write Subnet mask
wg : write Gateway
rs : read Subnet mask
rg : read Gateway
Change the IP assignment/IP address/SubnetMask/Gateway. Reboot the camera. The new IP
address/ subnet mask are used at the next power-up.

5.2 RS-232 Communication Cable
Figure 13. Serial Communications Cable RS-232B-12 (JAI Inc. part number: 310 132 19)
The RS-232B-12 interface cable is used to debug the PowerPC processor. This debug port is useful
when the network is down and RS-232 is the only choice to connect with the EN camera. See Section
3.6.3 on page 24 and Section 4.7 on page 31 for detailed information on how to use the debug
PowerPC port.
Note: Please make sure not to “hot” plug this cable into the camera (i.e. Plugging in while camera is
on), unless your laptop or desktop PC is properly grounded. A PC with a floating ground can
damage the internal circuit of the EN camera or your PC’s serial port as soon as the debug
(RS-232B-12) cable is connected.
5.3 Power Supplies and Power Cable Setup
5.3.1 Power Supplies
The EN Camera requires 12V DC power that is obtained through the 12-pin connector located on the
rear panel of the camera. PULNiX recommends the following power supplies:
PD-12UU
100-240V AC/12V DC
100-240 V AC
1.2A universal voltage power supply with US Plug
PD-12UUP
1.2A universal voltage power supply, with US Plug and
12-pin connector
PD-12UE
100-240V AC/12V DC
100-240V AC/12V DC
1.2A universal power supply with European Plug
PD-12UEP
1.2A universal power supply with European Plug and
12-pin connector
If you are providing power through the 12-pin connector, the PD-12UUP and PD-12UEP power
supplies are available with the 12-pin mating connector already attached to the leads from the
power supply. The PD-12UU and PD-12UE power supply can be connected to the JAI Inc. power cable
using a terminal strip or directly.
When wiring the PD-12UU and PD-12UE power supplies directly, please note the following:
•
•
The lead ends must be twisted together and tin-soldered for strength and electrical continuity.
Shrink tubing or a similar insulator should be used to prevent exposed leads from touching and
shorting.
•
•
The +12V lead is marked with a red stripe or white lettering; be sure not to reverse the leads.
All connections must be properly insulated to prevent shorting.
5.3.2 JAI Inc. Power Cables
If you are using JAI Inc. power cables such as the 12P-02S, please refer to the 12-pin connector pin-
out diagram. The cable pin-out diagram is shown in Figure 14 below. The color-coded leads use Gray
for Ground and Yellow for +12V.

5.3.3 Building Your Own Power Cable
Refer to the 12-pin connector pin-out in Figure 14 on page 35. Connect the Ground lead to pin #1,
and the +12V DC lead to pin #2 of the 12-pin connector. Power must be DC-regulated, and of
sufficient current to properly power the camera.
5.3.4 Attaching the Power Cable to the Connector
The 12-pin connector is keyed and will only fit in one orientation. Follow these directions to
properly attach the power cable to the camera connector:
1. Rotate the connector while applying slight pressure until the keyways line up.
2. Press the connector into place until firmly seated.
3. Plug the power cord into the 100V AC socket. This will power the camera up.
5.4 Attaching the Camera Lens
To attach the C-mount lens to the camera, carefully engage the threads and rotate the lens
clockwise until it firmly seats on the mounting ring. Do not force the lens if it does not seat
properly. Please note that some lenses with extremely long flangebacks may exceed the mounting
depth of the camera.

EN Camera Series
6 Camera Features
6.1 Progressive Scanning
Standard TV-system scanning is 525 lines interlace scanning as specified in the RS-170 protocol.
Every other horizontal line (odd lines and even lines) is scanned at a 60Hz rate per field, and the
scanning is completed with two fields (one frame) at 30Hz rate. Because of the interlace scanning,
the vertical resolution of CCD cameras is limited at 350 TV lines, regardless of the horizontal
resolution. When electronic shutter is applied, the CCD can hold only one field of charge at each
exposure. This means that the vertical resolution of the electronic-shutter camera is only 244 TV
lines. The situation is the same for an HDTV-format camera, since it has interlaced scanning and the
vertical resolution of the shuttered image is 500 lines.
The JAI EN camera uses a state-of-the-art progressive scanning interline transfer CCD which scans
all lines sequentially from top to bottom at one frame rate. Like a non-interlace computer screen, it
generates a stable, and crisp image without alternating lines.
The interline transfer architecture is also important to generate simultaneous shuttering. This is
different from full frame transfer architecture which requires a mechanical shutter or strobe light in
order to freeze the object motion.
The TS(C)-2030EN model (1920 x 512 resolution) enables the 30Hz frame rate by scanning 512 lines
out of the entire 1080 lines. This technique significantly reduces smear and blooming, which tend to
be significant problems in daylight outdoor applications such as intelligent transportation systems
(ITS).
The TS(C)-2076EN model (1920 x 768 resolution) enables the 21Hz frame rate by scanning 768 lines.
The TS(C)-2076EN has higher smear and blooming incidents than the TS(C)-2030EN. However, for
those applications that require more vertical resolution, users will find that the slightly higher
smear and blooming levels of the TS(C)-2076EN are a good trade-off and make it an excellent choice
for red light violation or speed enforcement use.
The TS(C)-1327EN model (1392 x 1040 resolution) enables the 15 Hz frame rate by scanning 1040
lines. Wider vertical FOV and high NIR sensitivity provide excellent choice not only for ANPR/LPR
tolling application but also for scene overview applications of Red light and speed enforcement.
The TS(C)-4032EN model (2048 x 1628 resolution) enables the 19 Hz frame rate by scanning 1628
liens out of the entire 2048 lines.
6.2 Asynchronous Reset
The video signal starts with internal VD. When the external VINIT pulse is applied, internal VD is
latched to HD and the internal VD is delayed to set up the shutter speed period. The shutter speed
is controlled by the dial switch from “0” to “F.” Video output timing starts right after the internal
VD and single shots, FDV is output at the internal VD timing.

6.3 ADR (Automatic Dynamic Range) Control
ADR (Automatic Dynamic Range) control is a key algorithm of EN cameras. The ADR algorithm
controls the EN camera parameters on a continuous basis to maintain the contrast-to-noise of the
license plates on passing vehicles to a suitable level required for automatic license plate reading
algorithms. The EN ADR algorithm is unique in that it requires no moving parts and can perform this
contrast maintenance function without having to take multiple images of a vehicle in order to
achieve the required plate contrast. The key to this ability is a separate smart light sensor. Each EN
camera can communicate with up to two smart light sensors. Using these smart light sensors, the EN
cameras automatically optimize Exposure time (or shutter speed), and Video Amplifier Gain (“Gain”
in short).
Using EN setup software, user can turn on or off ADR control by accessing “Camera ADR Control”
config register (Address = 50).
6.3.1 Camera ADR Control Related Registers
The following registers are accessible by users in order to switch ADR control on/off and fine-tune
the logic. ENSetup software can display these registers as well. Please refer to “EN to LC Interface
Document” for detail.
•
Camera ADR Control
Normally, the user must set to “ADR Control (using Light Sensor)” in order for the Light Sensor to
control the camera parameters (shutter, gain, vtop, vbot, pedestal). In “Debug” mode, the user can
set Light Sensor A and B values to “ADR Debug side A” and “ADR Debug side B” registers to simulate
the camera’s ADR control logic. “Manual” mode is for factory use only.
•
ADR LS Gain for Side A
This parameter is used to fine-tune cameras to environments with a different lighting conditions,
lenses, or optical filters. The raw A side reading of the light sensor is multiplied by “ADR LS Gain for
Side A”. If LSA_Gain > 1.0, the light sensor value becomes larger and the camera assumes the
lighting is brighter at that particular location, so it reduces the camera gain. If LSA_Gain < 1.0, the
light sensor value becomes smaller and the camera assumes the lighting is darker at that particular
location, so it increases the camera gain. This setting is used only for daytime, as the light sensor
value must be ZERO at night time.
Apply “ADR LS Gain for Side A” if the license plate in the daytime image is saturated to white. The
worst condition typically occurs on a bright sunny day when the sun is directly hitting the side of the
light sensor at 90 degrees.
•
ADR LS Gain for Side B
See “ADR LS Gain for Side A”. This gain is applied to Light Sensor Side B. Normally, it should be kept
at 1.0.
•
ADR Side A Offset
This parameter is used to fine-tune cameras to environments with a different lighting conditions,
lenses, or optical filters. “ADR Side A offset” is used only at night time while the night light is
turned on (the light sensor value moves below threshold). Normally, the light sensor value is ZERO
at night time. If you add a larger value to the “ADR Side A offset”, the camera adds this offset to
the raw light sensor value, and thus it reduces camera gain (the image becomes darker.)
Apply “ADR Side A offset” if your night light is too strong and the license plate in the night time
image is saturated to white.
•
ADR Side B Offset
See “ADR Side A offset”. This offset is applied to Light Sensor Side B. Normally, it should be kept at
0.
•
ADR Shadow Factor
42
Camera Features

EN Camera Series
Shadow factor is used to calculate the contrast of the Light Sensor A Side to the B Side of the light
sensor. Based on this Shadow Factor, the camera’s ADR logic optimizes the camera parameters
(exposure time, gain, vtop, vbot, pedestal). Please do not change this value and keep the factory
default (See EN to LC Interface Document for the factory default).
•
ADR Shutter Max
Based on the light sensor reading, the camera’s ADR (Automatic Dynamic Range Control) optimizes
the exposure time of the camera, and this setting is the upper limit of the exposure time range.
Normally, a monochrome camera is set to 500 usec, as the FlashHead strobes the light only for 500
usec. A color camera can hold a longer exposure time, but keep in mind that the motion blur is
severe if the “ADR Shutter Max” is longer than 1 msec. Increase “ADR Shutter Max” if the night
image is too dark and you can accept more motion blur.
•
ADR Shutter Min
Minimum or shortest exposure time that the camera ADR control will adjust to. Keep this to the
factory default (See EN to LC Interface Document for the factory default).
•
ADR Debug Side A
This value is read-only when “Camera ADR Control” is set to “ADR Control (using Light Sensor)”.
ENSetup software displays the raw reading of the light sensor A Side value. If “Camera ADR Control”
is set to “Debug” mode, you can write an A Side value to simulate the camera ADR. See “Camera
ADR Control”.
•
ADR Debug Side B
See “ADR Debug Side A”. This is for Light Sensor Side B.
ADR White-to-Blue Ratio
•
“ADR White to Blue Ratio” is the ratio between a white plate and blue plate, and is used to optimize
the camera parameters. This value is optimized by JAI, and should be kept at factory default.
Please do not change it.
•
Camera Shutter Mode
This is read-only status. Current setting of camera exposure time (dial). To find out Dial vs exposure
time (us) relationship, please see Operational Manual.
•
Camera Gain
This is read-only status. Current setting of camera gain.
Camera Vtop
•
This is read-only status. Current setting of camera ADC Vtop setting. Normally, Vtop is kept to 255.
The value is lowered only if the system needs extra gain in night time (Only 9720EN).
•
Camera Vbot
This is read-only status. Current setting of camera ADC Vbot setting. Vbot is kept to 0 at night time.
The camera’s ADR logic raises Vbot in sunny daytime to increase the contrast of the license plate.
6.3.2 Electronic Shutter
Normally, exposure time is controlled automatically by ADR (Automatic Dynamic Range) control
algorithm inside the EN, based on the output from light sensor. However during nighttime
installations it is often convenient to manually adjust the shutter time to a larger value so that the
focusing targets and vehicle used for setup are easily seen with the available road lighting. Manually
adjusting shutter speed can also be useful for certain types of debugging (See Section 7.2, “Problem
2: EN Setup Software Found the Camera, But the Video Image is Too Dark or Just Black,” on page
47).
The following exposure times are supported

When the EN camera is controlled by light sensor, user can monitor the shutter value in EN setup
software by accessing "Camera Shutter" status register (Address = 233). Note that this Shutter value
is dial number and not actual exposure time, (left side of the table above).
User needs to set appropriate "ADR Shutter Max" and "ADR Shutter Min" config registers (Address =53
and 58 respectively) to limit exposure time. In daytime, "ADR Shutter Min" limits the shortest
exposure time (or faster shutter speed). In night time, "ADR Shutter Max" limits the longest exposure
time (or slowest shutter speed). The factory default settings of "ADR Shutter Min" and "ADR Shutter
Max" are as follows: Factory Default Settings of the ADR Shutter Min. and Max.

6.3.3 Video Amplifier Gain Control
Normally, video amplifier gain is controlled automatically by an ADR (Automatic Dynamic Range)
control algorithm inside the EN, based on the output from the light sensor. However, the user can
manually change gain value by using the EN setup software (See Section 7.2 on page 47 for more
information). Normally, gain would be manually adjusted only when a different gain (and electronic
shutter setting) is needed to see the vehicle and focusing targets used for setup in whatever road
lighting is available at the installation site.

EN Camera Series
Note: Gain Value is Gain entry in camera LUT after calibration.
When the EN camera is controlled by a light sensor, user can monitor the gain value in the EN setup
software by accessing "Camera Gain" status register (Address = 232). This Gain value is the Gain
Table Entry in LUT after calibration (left side of the table above).
6.3.4 HDR Mode (4032EN Only)
By enabling HDR mode, the dynamic range increases by 12dB (x4). In other words, the camera can
include the meaningful grayscale information up to 4 times normal linear saturation level.
You can consider enabling this feature, if your application needs to avoid unexpected over-exposure
caused by reflection of sunlight, structural shadows, or large variations of plate reflections.
Normally, once the plate is over-exposed, there is no information to be extracted for post
processing such as LPR or matcher. HDR mode prevents the image from saturating too fast, while
maintaining the sensitivity in a dark area. Therefore, you can always capture readable plate images
regardless of severe abnormal conditions.
In the example above, Pixel P1 and P2 (dark pixels) continue integration without reset. Pixel P3 and
P4 (bright pixels) are reset and continue the integration from the dual-slope reset voltage.
Therefore, the saturation speed of the bright pixels can be slowed down, while maintaining detail
information in the dark area.
By using the light sensor, the camera automatically estimates the sensor saturation voltage, optimal
exposure time and gain. Then, the camera automatically adjusts the dual-slope reset voltage and
reset timing dynamically, in order to include an extra 12dB (x4) dynamic range. This process is fully-
automated to achieve a total 139dB system dynamic range.

To enable the HDR mode,
1. Start ENSetup software.
2. Open Video WIndow.
3. Right-click the camera icon, and select "Manual Exposure” menu item.
4. Click HDR mode check box and “Save in Camera” button. To disable HDR mode, uncheck the
box and click “Save in Camera” button.
If HDR mode is enabled, set the target grayscale of the license plate to 190~200DN, during the
installation, by adjusting “ADR A side Gain” (daytime), and “ADR A side Offset” (night time). See
section 6.3.1 for detail.
6.4 Flash/Nighttime Light Control

on the output from the light sensor. The user can manually turn on and off the strobe and night light
if necessary. You need to be able to access the following registers by means of the EN setup
software.
Register Address 10: Night Light Control
Register Address 11: Night Light ON threshold and Flash enable. Register Address 12: Night Light OFF
threshold and Flash enable. Register Address 50: Camera ADR Control
The distance and angle of the strobe unit toward the target is critical and must be optimized.
Please refer to the VIS400 Installation Manual for more information.
6.5 External Control
6.5.1 RS-485
The EN Camera has the ability to connect multiple cameras on the same RS-485 network. Each
camera has an individual ID number selectable via control registers; Camera RS-485 group register
(address=107) and Camera RS-485 address registers (address=109). Thus it is possible to send a serial
RS-485 trigger to any or all of the cameras. RS-485 communication is accessed via the 26-pin
connector on the rear panel of the camera.
RS-485 is typically used by the lane controller to send serial trigger or to send DatalD message to
validate the HW TTL trigger.
RS-485 is a differential signal communication for longer distance. Since RS-485 is not a common port
for PCs, a plug-in 485 board such as ULTRA-485 (Industrial Computer Source, San Diego, CA, 800-
523-2320) or compatible is required.
6.5.2 Ethernet
The primary benefit of Ethernet is the scalability of the system; you can add as many EN cameras as
you want to the system. For example, you can connect up to 255 Ethernet devices to one class A
subnet. Command/Status register access and image transfer are securely done over TCP/IP protocol.
In addition to the message-based TCP image transfer, sniffing image on UDP is also supported.
Captured images are buffered inside EN camera, and can be automatically transferred to FTP
server. Ethernet trigger can be used for applications where time critical response is not required as
hardware TTL trigger.
All functions over Ethernet are accessible by EN setup software. Please refer to VIS300/400EN Setup
User's Guide (Doc Number 4087-72-005).
6.6 Color Filter Array (Color Version)
The color filter array requires software to interpolate color. If the proper interpolation software is
not present the camera provides an 8-bit monochrome image. The necessary DLL is available from
JAI Inc.. The JAI Inc. EN Camera cameras use the Bayer color mosaic filter pattern (see Figure 16
below). The CFA contains 50% green photo sites and 25% red and 25% blue photo sites.
48
Camera Features

EN Camera Series
Figure 18. CFA Pattern
Because the color filter array contains only a single R, G or B color in each pixel, the restored image
has to fill in colors in the missing pixel locations. The software uses neighboring pixel information to
"guess" the missing colors to make smooth, clear images. This is called "color interpolation."
Because the EN Camera does not contain internal color-processing circuitry, viewer software must
perform color interpolation on host PC side. The EN setup software supports color interpolation.
After color interpolation, white balance must be properly done. Otherwise, gray or white objects
cannot be seen as gray or white. Each EN Camera (color) camera is calibrated in simulated daytime
condition and each image (TIF/JPEG) transferred to host PC contains Rgain and Bgain with regard to
Green. By decoding TIF/JPEG header, Viewer software can properly perform white balance. Please
refer to "LC To EN Interface Document" (Doc number 69-1198) for more information (color).
Please note that the factory default setting of the EN Camera (color) turns off Gamma correction,
because the non-linearity of the Gamma response curve degrades white balancing. Only linear LUT
is used.
Also, it is important to keep in mind that a lossy JPEG encoding will cause color information loss.
Viewer software cannot reconstruct the color image properly after it has been encoded to JPEG
format. In order to reconstruct the color properly, users must use the raw TIF image format only.
6.7 Image Formats
Two image formats are supported; TIF and JPEG.
The TIF Format image is always ON, and users cannot turn it off. "Image Acquisition 1" and "Image
Acquisition 2" config registers (Address = 3 and 9, respectively) control which image format to
choose. Multiple image formats, such as both TIF and JPEG, can be selected.
Whether you choose TIF or JPEG format, images sent by the EN cameras contain additional
information other than just pixel information. TIF/JPEG header includes ADR information (shutter,
gain, Vtop, Vbottom), TimeStamps, Network setting (IP address, MAC address), Error status, and
much more. Please refer to the "LC to EN Interface" document for details concerning TIF tagging.
6.7.1 TIF Format
The uncompressed (or raw) TIF format is the best choice to maintain the accuracy of the pixel
information for further image analysis and processing.
For the EN Camera (color) model, the user should deal only with the TIF format image, because
detailed color pixel information will be lost in the JPEG format image.
Please refer to the "LC to EN Interface" document for the detailed TIF header.

EN Camera Series
6.7.2 JPEG Format
JPEG is the industry-standard format for lossy image compression. Output file size, quality and
speed of the encoding depends on the quality setting. The user can set the proper quality setting by
accessing the "JPEG Quality Factor" config register (Address = 46). The factory default is 85.
Access to “Image Acquisition 1” and “Image Acquisition 2” config registers (Address = 3 and 9,
respectively) and turn on JPEG format. Factory default setting is TIF format only.
If JPEG quality factor is high (above 85) and image contains complex detail information, the output
file size of JPEG encoding becomes larger. JPEG image size must be properly defined in “Storage
Setup” of JPEG. If the output file size exceeds the pr defined JPEG image size, the result JPEG
image will not contain the full resolution of the image. Please refer to Section 6.9, “Image
Buffering,” on page 44).
For the EN Camera (color) model, the user should not deal only with the JPEG format image,
because this format will not retain detailed color pixel information.
Please refer to the “LC to EN Interface” document for details about the JPEG header.
6.8 Image Transfer
6.8.1 UDP Image Transfer on Setup Channel
The EN camera can send video images over TCP (message-based) on the control channel, or UDP
(sniffing mode) on the setup channel, or both. Image transfer over UDP is intended for live video
display to focus lens or for sniffing external triggers (HW TTL trigger, Ethernet Trigger, or RS485
Serial Trigger) without disturbing continuous normal operation with Lane Controller. The “Live” or
“Snap” buttons on the UDP setup channel do not send images to the FTP server or the lane
controller on TCP (message-based) image transfer. Half image and quarter images are supported
only on the UDP setup channel. The raw image format is the only one supported by the UDP setup
channel; JPEG is not supported.
UDP setup images are easy to enable and disable. The user can access the “EN Setup Trigger
Source” register (Address = 111) and “EN Setup Image size” register (Address = 112) to change the
trigger source and image size. Live image transfer can be slowed down by setting “EN Setup UDP
Inter-Packet Delay” register (Address = 110). It is important to note that when multiple host PCs
(clients) connect to the EN camera, only the last client who changes the “EN Setup Trigger Source”
register or “EN Setup Image size” register will receive the UDP setup image.
6.8.2 TCP Message-Based Image Transfer on the Control Channel
Image transfer over TCP is intended for more secure image transfer. Even if the packet is corrupt,
the TCP/IP mechanism automatically resends the missing/corrupt packets. Full size, Odd field, or
Even field images are supported and both raw TIF images and compressed JPEG images are
supported on TCP control channel.
Unlike the setup channel that can send only one uni-cast UDP image to a single client (host PC), the
control channel can send the identical image to multiple host PCs (clients) over TCP. However, the
host PC has to respond to “DATA_RDY” message that the EN camera sends when an external trigger
is input (HW TTL trigger, Ethernet trigger, or RS-485 trigger). If the host PC sends a “SEND_DATA”
message to the EN camera, then the EN camera sends TCP image (TIF, or JPEG, or both) over the
Control channel.
For detailed register and interface information, please refer to the “EN to LC Interface” document.
As a default, the EN setup software receives all images over UDP (setup channel). However, if you
prefer to switch to TCP images, you can do so by enabling the "Use TCP/IP" option. This is under the
"View" menu on the Video Window.

An API (application program interface) for Windows is available. Using an API, the time required to
develop software for device discovery, command communication, and image transfer can be
shortened. Please contact JAI Inc. for further information.
6.9 Image Buffering
Full size TIF images, JPEG images, and ODD/EVEN field images are independently managed in image
buffers. Each buffer is a sequential image queue. When the index reaches the last image, the user
can select either to overwrite the oldest image (or the first image), or to stop writing. Also, the user
can set the depth of the queue and the size of the JPEG image, while TIF, and ODD/EVEN field
image sizes are fixed. These image queue buffer operations are done using EN setup software by
accessing the "Storage Setup" command.
As a factory default, the image size and queue depth are defined as the following;

6.10 FTP
FTP (File Transfer Protocol) is the industry-standard file transfer protocol. All EN cameras have an
FTP client built-in. TIF image, JPEG image, or both can be transferred to the FTP server
automatically.
FTP server's IP address, username, password, and subdirectory name must be properly set by FTP
command. Additionally, a 2nd FTP server is supported in case the 1st FTP server is accidentally
down. Please refer to the “EN-to-LC Interface” document for the FTP command.
Additionally, the FTP server must be properly set up. Make sure to create a username and password,
and to allow read/write/modify access so that the EN camera can write image files in the sub-
directory of the FTP server's hard disk. FTP server's hard disk must be regularly cleaned up,
otherwise hard disk capacity becomes full and EN camera cannot write image files.
The default FTP port is 21, but the user can change this port number. Please refer to the
Troubleshooting section for various FTP server performance tests.

EN Camera Series
6.11 NTP (Network Time Protocol)
The EN Camera supports the NTP (Network Time Protocol) client. NTP is the industry-standard time
synchronization mechanism over the network. For LAN, the synchronization accuracy within a few
milliseconds is achievable. Normally, the EN cameras can maintain the accuracy within 10ms as a
worst-case scenario in LAN.
All NTP setup can be done using the EN setup software.
Using the EN setup software, user can access to “NTP client enable” config register (address = 60) to
turn ON or OFF the NTP feature. EN camera supports up to 3 NTP servers’ IP addresses (Config
register address = 61, 62, and 63).
For the first time when the EN camera is set up for NTP, the EN camera optimizes the drift of the
internal clock with regard to the NTP server in your LAN. This takes approximately 1-2 hours to
reach within a few millisecond range of the estimated error. This Drift file is saved in non-volatile
memory and when power is recycled, the EN camera will read the saved NTP Drift file and the next
settlement will not take too long.
If NTP is still not synchronized with the NTP server(s), “NTP status” register (address=239) shows
“UNSYNC” status (=0x40). After NTP is finally synchronized with NTP servers(s), “NTP status”
register shows “PLL” status (=0x01) and “NTP Estimate Error” status register (address=238) shows
the estimated clock drift from the NTP server(s).
If the “NTP Estimate Error” exceeds the values predefined in the “NTP Max Estimate Error” config
register (address = 64), then the EN camera sends an error message to the lane controller or any
client connecting to EN camera. Please refer to the “LC-to-EN Interface” document for details about
this error message.
If you decided to turn OFF the NTP feature, please keep in mind that clock drift is approximately
1.5 second per day. Therefore, you need to send an Ethernet command to synchronize the clock
from host PC on a regular basis (twice a day, every day, or every few days). Write “Real Time Clock
UTC” register (Address = 102). Please note that the internal millisecond counter is reset to zero
when you write a new value to the “Real Time Clock UTC” register

7 Frequently Asked Questions and Troubleshooting
7.1 Problem 1: What Password Allows Login from a RS232 Debug Port or Telnet
Session to the EN Camera?
User name = root, password = JAIPULNiX
7.2 Problem 2: What is a Password to Start the EN Setup Software?
The factory default setting is, user name = Administrator; password = Password. Once you log in for
the first time, you can change the administrator’s password or create a new user. Find “User
Administration” under the “Tools” menu item. The program allows you to manage your password,
user management, and security level setting.
7.3 Problem 3: Does the EN Color Camera Produce a 24-bit Color Image?
1. The EN color camera outputs an 8-bit CFA (Color Filter Array) monochrome image. Color
interpolation and white balance software are required in the host PC side to display a color
image. White balance parameters (R gain and B gain) are calibrated at the factory, and then
saved in the camera registers.
2. Turn off JPEG encoding, or you will lose color information.
7.4 Problem 4: EN Setup Software Does Not Find Any Camera in the Network
1. Make sure that your host PC and EN cameras have the same subnet address, and that their IP
addresses are not identical. If the EN camera’s IP address is 192.168.30.65, then you should not
set the same IP address to the host PC.
2. If you have a firewall set up on your Windows computer, disable it. Also, be sure to enable
network data transfer of the EN setup software.
3. If the EN camera’s IP address is unknown, use the RS-232 debug cable. For more information,
please see Section 2.2.2 (b on page 4.
4. If the EN camera is set to DHCP client mode, then you need DHCP server in your network.
Otherwise, a valid IP address is not assigned to the EN camera.
7.5 Problem 5: EN Setup Software Found the Camera, But the Video Image is too
Dark or Just Black
1. Make sure that the iris of the lens is open. If the light sensor is connected, then it is controlling
the camera parameters such as shutter, and gain. If the light sensor is set up outdoors and the
EN camera is set up indoors in the daytime, then the image will look very dark, because the
camera parameter is probably set to the highest shutter (1H exposure time), and lowest gain
(Gain=min).
2. If you want to manually set camera parameters instead of light sensor control, you can do so by
using EN setup software. In Video control window, right-click on the camera icon. Select
“Manual Video Adjust.” Set appropriate camera parameters manually. See Figure 6.2,
“Asynchronous Reset,” on page 36 for details about the camera parameters.

7.6 Problem 6: TTL Trigger/Ethernet Trigger/Serial RS-485 Trigger Does not
Generate Trigger
1. Make sure that the “Trigger” register is set properly to enable TTL Trigger/Ethernet
Trigger/Serial RS-485 trigger. In the “Properties” window of the EN setup software, you can
read/write “Trigger” register.
2. If you choose dataID source to be RS-485 or Ethernet, make sure to send dataID within the
pre/post message time window defined in those registers. If there is no dataID or the dataID is
sent after or before the predefined window, then the trigger will be rejected as an invalid
trigger. Make sure that you set the appropriate time pre/post message time window. The
factory default setting of dataID source is self-generate mode.
3. If the TTL trigger is noisy, then pre/post trigger condition filter may reject the trigger input to
the camera. TTL trigger must stay stable for a certain predefine pre-time before the trigger
edge and post-time after the trigger edge. If not, then the trigger will not be generated. The
factory default of pre- and post-time trigger is 1ms.
4. If TTL trigger pulse is noisy, then the trigger noise filter may reject the trigger input. TTL
trigger pulse width smaller than pre-defined trigger filter time is ignored automatically by the
FPGA as noise. The trigger noise filter factory default setting is 100us.
7.7 Problem 7: JPEG Image is Either Corrupt or Not a Full-Size Image
If the JPEG image size is set to be too small but the JPEG quality setting is too high, then the EN
will fail to save entire resolutions of JPEG. The user can either increase the size of JPEG image size
(See the Allocate Image Size section), or decrease JPEG Quality Setting. The factory default JPEG
image size is 300Kbyte, and quality setting is 85.
7.8 Problem 8: EN Camera Does Not Send any FTP Image to the FTP Server
1. Make sure that the FTP server allows anonymous user for full-access operation
(write/read/modify/ create directories).
2. If anonymous user is not used, make sure that the User Name, and Password on the FTP-client
register settings on the EN side match those of the FTP-server setting on the host side.
3. Make sure that the FTP-server has enough hard disk space to store TIF/JPEG images.
7.9 Problem 9: FTP servers switch between primary server and second server, even
if the hard disk is not full.
1. JAI has tested various FTP servers to compare performance differences. For Linux, we
recommend PureFTP server. We do not recommend vsFTP server. For Windows, we recommend
Cerberus FTP server. We do not recommend the IIS FTP server. Please contact JAIPULNiX for
detail test data.
2. By increasing the time-out duration and retry count of FTP transfer, one can avoid accidentally
switching between FTP servers. However, if you move the time-out and retry count too high,
the EN Camera's image buffer (TIF or JPEG) may overflow and start losing images, depending on
the frequency of the incoming triggers. The factory default is (OpenTimeout, DataPortTimeout,
ControlPortTimeout, Max_Retry) = (1,1,1,3).
3. Make sure to turn off the logging feature of the FTP server. Logging decreases the host PC's
system memory.
4. Limit the number of files under the same subdirectory. The factory default setting is 1000 files.
If the system allows several thousand files in the same subdirectory, the FTP server performance
degrades significantly .

7.10 Problem 10: The EN Camera Does not connect to light sensor.
1. Make sure to set the proper IP address and port number for the light sensor in the EN registers.
2. Verify that the ADR register is set to "Auto" to connect to the light sensor.
7.11 Problem 11: Light Sensor Connection is Not reliable.
Inconsistent light sensor connection and communication can be solved with the following changes;
For UDP connection (Recommended. Max connection = 128):
1. Access to HTTP server of MOXA (RS-485 to Ethernet converter). Check the version of firmware.
Firmware must be 2.2 or later. If not, update the firmware.
2. Go to “Operating Settings” -> “Port 1” Change the following parameters.
3. Operation Mode
UDP mode
4. Type the IP address of your EN cameras. Try to minimize the number of IP addresses, otherwise
MOXA will transmit multiple messages.
For example, if the IP address of your EN cameras are 0.0.0.60, 10.0.0.70, 10.0.0.80, then, do
not try to set the up as: "10.0.0.60 ~ 10.0.0.80". MOXA would transmit the same messages to 21
clients in this scenario.
Instead, set up the up as: "10.0.0.60 ~ (none)
example transmits to only 3 clients.
10.0.0.70~ (none), 10.0.0.80~(none)". This
5. Make sure to set UDP mode in EN LightSensor register.
6. If you want the EN camera to connect multiple MOXA devices (up to 2 MOXAs), do not assign the
same port number for performance reasons. Assign different port numbers.
For TCP connections (not recommended, but for customers who require TCP connections). The
maximum number of connections is four:
1. Access to HTTP server of MOXA (RS-485 to Ethernet converter). Check the version of firmware.
Firmware must be 2.2 or later. If not, update the firmware.
2. Go to “Operating Settings” -> “Port 1” Change the following parameters.
3. Operation Mode
• TCP alive check time
• Ignore jammed IP
TCP Server mode
1 min
YES
4. Repeat the same changes to "Operating Settings"-> "Port 2".
5. Make sure to add 120Ohm termination resistor to the very end of MOXA RS485 data port. See the
VIS-300 Installation Manual for diagram.
7.12 Problem 12: IO Board Communication Error
The IO board has a temperature sensor, a housing-open sensor, and other event sensors. When these
events occur, the IO board sends a warning to the EN camera through the 9600 bps UART. If you are
not using an IO board and a 26-pin HD-Sub cable, then you will have an IO board communication
error message. In this situation, you can simply ignore this message.
If you are using an IO board and a 26-pin HD-Sub cable and still see an IO board communication
error, then the baud rate of the EN camera may not match that of the IO board communication
UART. In this situation, you need to set the EN IO board rate register to 9600 bps, so that it matches
the IO board UART factory default (9600bps).

7.13 Problem 13: Night Time Image is Too Bright and License Plate is Whited Out or
Saturated
1. Make sure that the light sensor is connected to the EN camera (Set ADR register to Auto).
2. Add ADR A offset to reduce the gain at night time. ADR offset is used only when the night light is
turned on. When ADR A offset is high, the EN camera reduces the system gain and the brightness
of the license plate is reduced. Add only to ADR A offset.
7.14 Problem 14: The Day Time Image is too Bright and Whites Out or Saturates the
License Plate
1. Make sure that the light sensor is connected to the EN camera by setting the ADR register to
Auto.
2. Add the ADR A side gain to reduce the gain at daytime. If B side is facing toward the same
direction as the license plate, apply the ADR B side gain, instead.
3. The factory default setting is 1.00, but it can be changed up to 1.35 to reduce the camera's
system gain. The ADR A and B side gain are used only when the night light is turned off (only in
daytime).
7.15 Problem 15: Flash_Erorr Appears in the Error Register
1. If you use an AC Flash Unit, enter 1 in the config register (address = 42 decimal) so that the
flash status is "Normally High. Goes Low at alarm."
2. If you use DC Flash Unit, enter 2 to config register (address = 42 decimal) so that flash status is
"Normally Low. Goes High at alarm."
3. After changing the register, save the setting to FlashROM.
7.16 Problem 16: Timestamp is Not Set to Current Local Time
1. Use the EN setup software to set local time. In the “Property” window, find the “Real Time
Clock” register. If NTP is OFF, then the displayed time is estimated to drift about 1.5 second per
day.
2. If NTP is ON, then the time is automatically synchronized with the NTP server. However, the
timestamp inside the TIF/JPEG header is UTC in GMT time zone. The viewer’s software will
need to decode the UTC (GMT time zone) to sync appropriately with local time.
