GE DVMRe user manual Camera Inputs, Composite Monitor Output, Alarm I/O Port

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.

Cable: 75-Ohm Coaxial

Connectors: BNC

Auto Terminating: Yes

Passive Looping: Yes

This means that the input signal will automatically be terminated with 75-Ohms unless a 2nd cable is connected to the 2nd BNC connector of the same camera input. Make sure there is 75-Ohm termination at the end of the video line if the signal is looped through the DVMRe Triplex.

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 Triplex to the monitor, select the 75-Ohm impedance setting on the monitor.

Cable: 75-Ohm Coaxial

Connectors: BNC

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 and S-Video.

Cable: 75-Ohm Coaxial

Connectors: BNC

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	DB-25 Connector on Back Panel
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.
