● To Confirm the Images from a
Recorder Connected to the Unit
The following is the description of the connection between a
recorder and this unit to confirm the images from the
recorder.
1. Set the unit address of the recorder to 1. Then, confirm
that the recorder’s CAMERA GENLOCK is set to OFF in
its SETUP MENU. (Refer to the recorder's operating
instructions.)
2. Connect the unit’s CAM OUT 1 to 16 connectors to the
recorder’s VIDEO IN 1 to 16 connectors with a coaxial
cable.
3. Connect the unit’s EXT IN connector to the recorder’s
MULTI SCREEN OUT connector with a coaxial cable.
4. Connect the unit’s DATA HDR connector to the
recorder’s DATA port with a modular cable.
(The control data and alarm signal will be output from
the unit to the recorder.)
Notes:
• You cannot record the camera images in maximum
recording rate through this connection. Refer to the next
connection example in this page.
■ Connection with the Alarm
Output
Pins #10, 11, 23 and 24 (open collector) turns to 0 V while
the alarm is activated. These terminals can drive external
warning devices such as a buzzer or lamp of up to 100 mA,
16 V DC. If the rating exceeds 100 mA, 16 V DC use a relay
as shown in Example 2.
Alarm signals are output from the terminals until the reset.
Example 1: Direct drive connection
Example 2: Connection of devices exceeding drive
Note: An alarm signal is output from the Master unit and a
unit activated by the alarm. Be careful of connections
as the Master unit outputs alarm signals to directly-con-
nected devices any time when an alarm is activated.
