• Location outside the allowed operating temperature range (0°C ~ 40°C) where the temperature may become extremely hot or cold.

• Location outside the allowed operating humidity range (30% ~ 80%) where the humidity is high.

• Location with strong magnetic force such as from a transformer, motor, etc.

• 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.

• Location where radiation, x-ray or corrosive gas

is generated.

Handling

■ To prevent the internal temperature from rising, do not stack units when using.

■ Do not place the unit on its side.

■ Handle the unit with caution and do not apply ex-

cessive force.

■ 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.

■ 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.

■ About the echo canceller The echo canceller of the unit is provided for the prevention of howling. However, repeated echoing 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 direction of the microphone or take caution so that the playback sound from the speaker is not picked up by the microphone. When using a camcorder with audio AGC (Auto Gain Control), the echo canceller may not work properly. Please turn off the AGC. If the AGC feature cannot be turned off , use a separate microphone amplifier with no AGC.

■ When not using the unit for a long time, turn the power of the unit off for conserving energy.

Camera mode - Camera mode

Only audio will be played back.

Observing the video and audio using another DM-NC40 unit (observer mode)

Observing stream is available by connecting another DM-NC40 unit to working DM-NC40.

• Camera mode accepts observing at the time of shipment. For teleconference mode, a setting change using

API is required to accept observing. ( Page 54)

Remote Monitoring system (Camera mode and Monitor mode)

Observing is available by connecting from Monitor mode to Camera mode that is connected already to another Monitor mode.

(At this time, ENCODE display lamp: OFF, DECODE display lamp: ON, SELECT button light: OFF (operation disabled), PinP button light: OFF (operation disabled) on the observing unit.)

* The automatic recovery feature does not work with observing unit. Please reconnect.

Teleconference system (Teleconference mode and Teleconference mode)

After observing is enabled by API, observing is available by connecting from teleconference mode to teleconference mode that is connected already to another teleconference mode.

(At this time, ENCODE display lamp: OFF, DECODE display lamp: ON, SELECT button light: OFF (operation disabled), PinP button light: OFF (operation disabled) on the observing unit.)

ask to network administrator.

3 Set the default gateway.

Reconnect to the changed IP address using the Web browser

• When the IP address of the DM-NC40 is changed, you need reconnect with new IP address for more

settings by Web browser. Example: When changing the IP address from 10.0.0.1 to 10.0.0.10

Enter http://10.0.0.10 in the address bar of the browser. ( See page 26)

• To connect from PC to new IP address of the unit, changing IP address and subnet mask of PC may be

required in some cases. Example: When changing IP address of DM-NC40 from 10.0.0.1 to 192.168.0.1

and Subnet mask from 255.0.0.0 to 255.255.255.0

You may change IP address of PC from 10.0.0.2 to 192.168.0.2 and Subnet mask from 255.0.0.0 to 255.255.255.0

Connection can be reestablished by entering http://192.168.0.1 in the address bar of the Web browser.

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.

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 Gatew a y, 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. When the power is turned on, the unit performs initialization and current IP address is displayed twice on the connection number display of the unit.

Display example when the IP address is 10. 0. 0. 1:

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.
