Introduction  
About this Manual  
This manual describes how to install, configure, and operate the Extron IN1502  
video scaler and how to operate the optional IR 901 infrared remote control  
(part #70-152-01).  
Throughout this manual the terms “IN1502”, “video scaler”, and “scaler” are  
used interchangeably to refer to the same product.  
About the IN1502  
What is the IN1502?  
The IN1502 is a video scaler that offers 16 output rates and provides scaling  
solutions for boardrooms, conference rooms, and home theaters, as well as rental  
and staging applications.  
To enable superior scaling performance, the IN1502 features several of Extron’s  
patented and patent-pending technologies, including Dynamic Motion  
Interpolation (DMI) technology, and 3:2 and 2:2 pulldown detection. DMI is an  
advanced motion detection and compensation method that enables image  
enhancement with no loss of image fidelity.  
The IN1502 scales composite video and S-video up to computer video (RGBHV/  
RGBS), which can be output to a display device via a 15-pin HD connector.  
Controlling the IN1502 video scaler  
The IN1502 can be controlled using one or more of the following methods:  
• The front panel controls  
• A computer, a touch screen panel, or any other device that can send and  
receive the serial communications through the RS-232 port. Extron’s  
Simple Instruction Set (SIS) is a set of simple keystroke commands that  
can be used with any such devices.  
• The optional IR 901 remote control, which has most of the front panel controls  
Features and Options  
Features  
Two video inputs  
Input 1 — One BNC connector on the rear panel accepts a composite video  
signal.  
Input 2 — One 4-pin DIN connector on the rear panel accepts an S-video  
signal.  
Video output — One VGA-type 15-pin HD connector provides an RGB output.  
Three ways to control the scaler — The scaler’s front panel, a computer or other  
RS-232 control device, or the optional IR 901 remote control can all be used  
to control the scaler.  
Scaled outputs — The IN1502 offers 16 different output rates.  
RS-232 configuration — The IN1502 can be configured by using a control  
system.  
Dynamic Motion Interpolation (DMI) — This video processing technique is an  
advanced motion prediction and compensation method that treats motion  
content and still content with different algorithms to yield high fidelity  
images.

3:2 pulldown detection for NTSC and 2:2 film detection for PAL video  
sources — These advanced film mode processing features help maximize  
image detail and sharpness for video sources that originated from film.  
When film is converted to NTSC video, the film frame rate has to be  
matched to the video frame rate in a process called 3:2 pulldown. Jaggies  
and other image artifacts can result if conventional deinterlacing  
techniques are used on film-source video. The IN1502’s advanced film  
mode processing recognizes signals that originated from film. The  
IN1502 then applies video processing algorithms that optimize the  
conversion of video that was made with the 3:2 pulldown process. This  
results in richly detailed images with sharply defined lines. A similar  
process is used for PAL film-source video.  
Versatile mounting options — The IN1502 is 1U high, and a half rack wide. It is  
rack mountable, or it can be placed on a table or other furniture. Rubber  
feet are included.  
Options and accessories  
The IN1502’s optional equipment includes:  
IR 901 remote control — Extron’s IR 901 (part #70-152-01) is an infrared  
remote control which replicates all of the front panel controls of the  
IN1502 except the Menu and Next buttons.  
Rack shelf mounting kit — The 1U high, half rack width IN1502 can be rack  
mounted using the universal rack shelf mounting kit (part #60-190-01) or  
the basic rack shelf mounting kit (part #60-604-01).

Installation and Operation  
Mounting the Scaler  
UL rack mounting requirements  
The following Underwriters Laboratories (UL) requirements pertain to the safe  
installation of the IN1502 in a rack.  
1.  
Elevated operating ambient temperature — If installed in a closed or  
multi-unit rack assembly, the operating ambient temperature of the rack  
environment may be greater than room ambient temperature. Therefore,  
install the IN1502 in an environment compatible with the maximum  
ambient temperature (Tma = +113 °F, +45 °C) specified by Extron.  
2.  
3.  
4.  
Reduced air flow — Install the equipment in a rack so that the amount of  
air flow required for safe operation of the equipment is not compromised.  
Mechanical loading — Mount the equipment in the rack so that a  
hazardous condition is not achieved due to uneven mechanical loading.  
Circuit overloading — Connect the equipment to the supply circuit and  
consider the effect that circuit overloading might have on overcurrent  
protection and supply wiring. Appropriate consideration of equipment  
nameplate ratings should be used when addressing this concern.  
5.  
Reliable earthing (grounding) — Maintain reliable grounding of rack-  
mounted equipment. Pay particular attention to supply connections other  
than direct connections to the branch circuit (e.g. use of power strips).  
Tabletop/desktop placement  
For tabletop or desktop placement only, install the self-adhesive rubber feet/pads  
(provided) onto the four corners of the bottom of the enclosure.  
Rack mounting  
1.  
If feet were installed on the bottom of the IN1502, remove them.  
2.  
Place the IN1502 on one half of the 1U (one unit high, one unit wide) rack  
shelf (part #60-190-01 or #60-604-01). Align the front of the IN1502 with  
the front of the shelf, and align the threaded holes on the bottom of the  
IN1502 with the holes in the rack shelf.  
3.  
Attach the IN1502 to the rack shelf with the two provided 4-40 x 3/16"  
machine screws. Insert the screws from the underside of the shelf, and  
securely fasten them into diagonally-opposite corners.  
See the following illustration.

Optimizing the System for a DVD Player  
For optimal performance, follow the steps in this section in order when setting  
up the IN1502 for a DVD player.  
Setting up a DVD source  
To get the best results when using a DVD as a video source, Extron recommends  
that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3.  
Because all DVDs are mastered as 16:9, having them set up for anything else will  
cause the player to internally scale and compress the signal. This scaling/  
compression by the DVD player will defeat the advantage of having 3:2  
pulldown detection in the IN1502.  
All sizing adjustments to correct aspect ratio should be done using the IN1502.  
To change the output aspect ratio of most DVD players,  
1.  
2.  
Enter the DVD player’s Setup or Action menu while the disc is stopped.  
Select a 16:9 aspect ratio.

IR 901 Infrared Remote Control  
The IR 901, shown at right, replicates all of the front  
panel controls except the Menu and Next buttons. If  
Executive mode has been enabled on the IN1502, input  
selection and adjustments can still be made from the  
IR 901. You must use the IN1502’s front panel, a host  
computer, or an RS-232 control device to configure and  
program the scaler. See chapter 3, “Serial  
Communication”, for details.  
The topmost part of the IR 901 features three Aspect  
Ratio Preset buttons (not functional), a Freeze button,  
and two input selection buttons (1 and 2). Inputs 3, 4,  
5, and 6, and the Take button are not functional. The  
middle portion of the IR 901 features the size and  
centering buttons. The bottom part contains the  
adjustment controls for color, tint, brightness, contrast,  
and detail adjustments. The sharpness buttons are not  
functional.  
Freeze an input  
To freeze the input being displayed, press the Freeze  
On/Off button. To unfreeze the input, press the Freeze  
button again.

Troubleshooting  
This section gives recommendations on what to do if you have problems  
operating the IN1502, and it provides examples and descriptions for some image  
problems you might encounter.  
The following are some tips to help you in troubleshooting.  
1.  
Some symptoms may resemble others, so you may want to look through all  
of the examples before attempting to solve the problem.  
2.  
3.  
Be prepared to backtrack in case the action taken doesn’t solve the problem.  
It may help to keep notes and sketches in case the troubleshooting process  
gets lengthy. This will also give you something to discuss if you call for  
technical support.  
4.  
5.  
Try simplifying the system by eliminating components that may have  
introduced the problem or made it more complicated.  
For sync-related problems: Portable digital projectors are designed to  
operate close to the video source. Sync problems may result from using  
long cables or from improper termination. A sync adapter, such as Extron’s  
ASTA (active sync termination adapter), may help solve these problems.  
6.  
For LCD and DLP projectors and plasma displays: In addition to the sync-  
related information above, check the user’s manual that came with the  
projector for troubleshooting tips, as well as for settings and adjustments.  
Each manufacturer may have its own terms, so look for terms like “auto  
setup”, “auto sync”, “pixel phase”, and “tracking”.  
Operating problems  
The table below shows some common operating problems and their solutions.

Serial Communication  
The IN1502 can be remotely controlled via a host computer or other device (such  
as a control system) attached to the rear panel Remote connector. The control  
device (host) uses Extron’s Simple Instruction Set (SIS) commands.  
The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control.  
The rear panel RS-232 9-pin D connector has the following pin assignments:

Host-to-scaler communications  
SIS commands consist of one or more characters per field. No special characters  
are required to begin or end a command sequence. When the IN1502 determines  
that a command is valid, it executes the command and sends a response to the  
host device. All responses from the scaler to the host end with a carriage return  
and a line feed (CR/LF = ), which signals the end of the response character  
string. A string is one or more characters.  
It is also possible to send several SIS commands back-to-back in sequence.  
Scaler-initiated messages  
When a local event such as a front panel selection or adjustment takes place, the  
IN1502 scaler responds by sending a message to the host. No response is  
required from the host. The scaler-initiated messages are listed here  
(underlined).  
(C) Copyright 2005, Extron Electronics, IN1502, Vx.xx  
The IN1502 sends the copyright message when it first powers on. Vx.xx is the  
firmware version number.  
X1  
X1  
C hn  
(where  
is the input number)  
The IN1502 sends this response when an input is switched.  
Error responses  
When the scaler receives a valid SIS command, it executes the command and  
sends a response to the host device. If the IN1502 is unable to execute the  
command because the command is invalid or it contains invalid parameters, it  
returns an error response to the host.  
The error response codes and their descriptions are as follows:  
E01 – Invalid input channel number  
E10 – Invalid command  
E13 – Invalid value (the number is out of range/too large)

Firmware Upgrade Installation  
In some cases, the IN1502’s firmware may require replacement with an updated  
version. There are three user-replaceable firmware chips: U41 — the main  
microcontroller, U38, and U17. The numbers are printed on the circuit board. We  
recommend that you send the unit to Extron for service and updates.  
Changes to firmware must be performed by authorized service personnel  
only. Some IN1502 firmware updates must be performed at the Extron  
factory.  
Follow these steps to replace firmware in the scaler.  
1.  
Disconnect the AC power cord from the IN1502 to remove power from the  
unit.  
To prevent electric shock or damage, always unplug the IN1502 scaler  
from the AC power source before opening the enclosure.  
2.  
3.  
Remove the scaler from the rack or furniture.  
Remove the cover of the scaler (the top half of the enclosure) by removing  
the four screws, then lifting the cover straight up.

Do not touch any switches or other electronic components inside the  
scaler. Doing so could damage the scaler. Electrostatic discharge (ESD)  
can damage IC chips even though you cannot feel it. You must be  
electrically grounded before proceeding with firmware replacement. A  
grounding wrist strap is recommended.  
4.  
Locate the firmware chip(s) to be replaced on the circuit board, as shown in  
the following illustration.

5.  
After you are electrically grounded, you can remove the U17 IC chip or U38  
IC chip by grasping it firmly with your fingers and pulling it out; then  
continue to step 8.  
Removal of the U41 IC chip requires a PLCC IC puller  
tool. To remove the U41 chip, align the hooks of a  
PLCC IC puller tool with the slots located in opposite  
ends of the U41 firmware chip.  
6.  
Insert the hooks into the slots, and squeeze the tool  
gently to grasp the chip.  
7.  
8.  
Pull the chip straight out of the socket, and set it aside.  
For U17 and U38, align the notch of the new firmware  
chip with the notch of the socket in the same  
orientation as the old chip.  
For U41, align the angled  
corner of the firmware  
Align Notches  
chip with the angled  
corner of the socket.  
U41  
9.  
Gently, but firmly, press  
the chip into place in the  
socket.  
10. Replace the top cover on the IN1502 scaler, and fasten  
it with the screws that were removed in step 3.  
11. Rack or furniture mount the scaler, and reconnect the AC power cord.
