Camera Inputs; Composite Monitor Output - GE Security DVMRe Simplex User Manual

14. RS485 Port 2 Connector: For connecting to keyboard and other RS485 devices.
15. RS232 Port 2: For Event Generation and ASCII Text insertion.

Camera Inputs

There are two BNC jacks for each camera. Either
jack can receive a camera signal. The signal is
looped (directly connected to the other jack), making
the camera signal available to other equipment.
The camera input connectors are Auto Terminating.
This means that the input signal will automatically be terminated with 75-Ohms unless a 2
nd
connected to the 2
termination at the end of the video line if the signal is looped through the DVMRe Simplex.
Time base correction is performed during digital capture. As a result, cameras do not require
synchronization.
See section 3.14 for information about disabling unused camera jacks in the menu system.

Composite Monitor Output

When connecting directly from the DVMRe Simplex
to a monitor, select the 75-Ohm impedance setting
on the monitor.
If an additional device is connected to the monitor's looping output, set the termination of the additional
device as 75-Ohm, and set the termination of the monitor as Hi-Z (High Impedance).
Y/C Monitor Output
Y/C video output has a 4-pin mini-DIN style
connector. This style of connection is also referred to
as SVHS or S-Video.
Alarm I/O Port
The back panel of the unit is equipped with an Alarm
Port (DB-25 style connector).
Do not attempt to wire directly to the DB-25
connector on the back panel.
Connect the Alarm PCB (supplied with the unit) to the Alarm Port. Wire all alarm inputs to the Alarm
PCB per the pin out specifications shown below.
