Cautionary Notes
I About the echo canceller
Storage/usage location
The echo canceller of the unit is provided for the
prevention of howling. However, repeated echo-
ing of sound other than from a DM-NC40 may not
be suppressed sufficiently.
When using a speaker and a microphone at the
same time, place them apart, change the direc-
tion of the microphone or take caution so that the
playback sound from the speaker is not picked up
by the microphone.
I Do not use or store the unit in the following loca-
tions. Malfunction may occur as a result.
• Location outside the allowed operating tem-
perature range (0°C ~ 40°C) where the tem-
perature may become extremely hot or cold.
• Location outside the allowed operating humid-
ity range (30% ~ 80%) where the humidity is
high.
When using a camcorder with audio AGC (Auto
Gain Control), the echo canceller may not work
properly. Please turn off the AGC.
• Location with strong magnetic force such as
from a transformer, motor, etc.
If the AGC feature cannot be turned off, use a sepa-
rate microphone amplifier with no AGC.
I When not using the unit for a long time, turn the
power of the unit off for conserving energy.
I About electrical interference
• Location with presence of electric waves such
as from a transceiver, mobile phone, etc.
• Location that is dusty or sandy.
• Location with strong vibrations.
• Location with condensation.
When using the unit near a television, radio re-
ceiver or transceiver, screen images may become
disturbed or noise may be heard. In this case, try
the following:
• Location where radiation, x-ray or corrosive gas
is generated.
Handling
• Place the unit away from radios and televisions
or change the direction of the unit.
I To prevent the internal temperature from rising,
• If an indoor antenna is used, change the direc-
tion or the location of the antenna.
do not stack units when using.
I Do not place the unit on its side.
• Use a wall outlet other than the one used for
radios, televisions, etc.
I Handle the unit with caution and do not apply ex-
cessive force.
•
Install a commercially-available noise filter be-
tween the wall output and power plug.
I Wipe the unit with a soft cloth.
The surface may fog or even melt when wiped
with benzene or paint thinner. For stubborn dirt,
use neutral detergent diluted in water and then
dry wipe.
I To completely cut off the power, disconnect the
power cable from the wall outlet or remove the
power cord from the AC inlet (AC IN) of the unit.
JVC assumes no responsibility whatsoever of
any effects that may occur as a result of
operating this unit.
Installation
I Be sure to ground the unit.
I Place the unit near a wall outlet.
I Always use the specified (included) power cord.
Use of a cord other than that specified or a cord
that has been damaged may result in fire or elec-
trical shock.
I Do not use the included power cord other than
with this unit.
I Do not place heavy objects such as a monitoring
television on top of the unit. Malfunction may oc-

Memo
• When in the Teleconference mode or Monitor mode, set Bitrates for all DM-NC40 units so that they have same
color on the bitrate select bar.
• When setting a high bit rate, the video may not play back smoothly depending on the input video. However, this
is not a malfunction of the unit. If keeping frame rate is more important than picture quality, lower the bitrate.
When bitrate and frame rate settings are low, interval of video frames becomes long and delay time looks to be
long.
• When complicated video source is inputted, video delay become ling for while.
• The audio rate will be as shown below.
When the audio format is G.726
When the audio format is AAC-LC

Cautions when changing settings
• To check current communication, refer to “Telnet Settings” on page 53 and execute the “stat” command.
• Do not change settings during CF recording. Malfunction may occur as a result.
• Set values in this page are default values. Working ENCODER PARAMETERS can be changed by request from
other units. Working values are displayed in this page during communication, and default values are displayed
during stop. If same settings are used to each units, such confusion can be avoided. Same settings are recom-
mended to avoid problems during automatic recovery after power on.

When configuring remote monitoring system, set same frame rate to camera mode unit and monitor mode unit. Set bitrates
within same color on the select bar to all units.
Settings are performed in the ENCODE PARAMETERS screen for both camera mode unit and monitor mode unit (੬page 32).
Monitor mode can set encode parameters for each destination camera side unit in the TELEPHONE BOOK screen.(੬page 34)
When settings in camera side and monitor side are different, connection may take for a few seconds because settings are
changed during connection. JPEG recording will also be unavailable during this time.
Same settings are recommended for units used for automatic alarm connection. (੬page 38).

DHCP Operation and IP Address Display during Startup
DHCP Operation
DM-NC40 supports DHCP.
If there is DHCP server in same LAN, network settings, i.e. IP address, subnet mask, default
gateway, are provided from the DHCP server to the unit after power on or rebooting.
After turning on the power or rebooting, the unit displays IP address. If there is DSCP server
in same LAN, provided IP address from the DHCP server will be displayed on the front of the
unit.
If there is no DHCP server, IP address “10 0 0 1” is displayed after about 2 minutes and the
IP address and subnet mask are set to the default values of 10.0.0.1 and 255.0.0.0,
respectively.
If the IP address could not be acquired:
After about 2 minutes
Initialization operation
When DHCP server is not available, network settings by manual may be required. Use Web
browser (see page 30) or API commands described in page 54 to change the setting to
“Manual”.
* Changing from DHCP to Manual is possible from Web browser, but you need to use API
command to change from Manual to DHCP.
* During DHCP is enabled, IP Address, Subnet Mask, Default Gateway, Domain Name and
DNS Server settings cannot be set from Web browser.
IP Address Display
The IP address is displayed after the power of DM-NC40 is turned on.

Operating with CF Card Reader
With the CF card reader, you can read image files recorded in a CF card. Remove the CF
card from DM-NC40 and set it to the CF card reader.
Caution:Windows cannot read CF cards formatted to Ext2. Please format the CF card to FAT32.
Image files are recorded in CF cards as follows.You can open the files using standard software
on Windows.You can also move, copy, or delete files with standard Windows software.
Alarm-recorded image folders (“alarm 1 ~ 4”
are image folders recorded by alarm 1 ~ 4.
“manual” is image folder recorded using panel
operation of the unit.)
Each image folder contains 2 folders:
Jpeg-1: Image folder of VIDEO IN1
Jpeg-2: Image folder of VIDEO IN2
Each image is saved using the file name shown below in jpeg-1 or jpeg-2 folders.

About the Alarm (Continued)
Alarm notification using API
When alarm settings are set to send alarm information to DM-NC40 with API, the monitor mode DM-NC40 that
receives the notification works as follows: (For details on settings, see page 37)
1. If the source unit is registered in the telephone book, the number of source unit flashes on the number
display of the monitor unit.
2. If the monitor is connected to another unit, the connection is disconnected when the PLAY button is
pressed, and new connection to the source unit is made.
3. When monitor unit receives multiple alarms from many source units, and if STOP button is pressed
instead of PLAY button, each source unit numbers flash on the panel. If there are no more alarms, the
unit will return to the previous connection before the first alarm.
Memo
• Up to 10 alarm notifications can be handled as above.
• When connected with PLAY button, encode parameters in the telephone book of the monitor unit are used. If
there are multiple registrations having same IP addresses in the telephone book, smallest Edit No. is used. (In
observing mode, monitor unit obeys settings of camera side.)
• Alarm notifications from DM-NC40 units not registered in the TELEPHONE BOOK is ignored.
• Alarm notifications from current connecting DM-NC40 is ignored.
• If the acceptance is set to automatic (AUTO), monitor unit connects to the alarm source unit automatically
without pressing PLAY button.
• If the acceptance is disabled (OFF), alarm notifications is ignored. (Acceptance setting can be changed in
NETWORK SETUP screen.)
• When encode parameters of camera mode are changed by connection from monitor mode, image file recording
is stopped during the parameter change is in progress. Same settings to both camera mode and monitor mode
are recommended to avoid such problem.
• Alarm notification is ignored during IP address display at start.
