1 Controlling a VDM Digital Recorder

1.1 Full Remote Control and Display of Main Monitor

Full remote control of a VDM and display of the main monitor may be achieved by connecting up a VK-1
Keyboard and composite video monitor as shown below.

MONITOR

DIGITAL RECORDER

75 Ohms

ON

IN

BNC

CABLE

VK-1 KEYBOARD

CAT5

CABLE

Note that the control from the Keyboard to the Digital Recorder uses one twisted pair, the video from the
Digital Recorder to the Keyboard uses another pair, and the 12V DC power from the Digital Recorder to the
Keyboard uses another pair.

The above configuration is satisfactory for cable runs up to 200 metres. Above this distance, the video
quality will degrade and it is recommended that a coax video cable be run directly to the monitor.
Additionally, the 12V power supply provided should be plugged into the VK-1 as voltage loss along the
twisted pair cable may be too great. With this alternative connection configuration, only one twisted pair core
is actually used, and cable runs up to 1000m are possible.

If display of the Spot monitor output is also required, a separate video cable will be needed, running from the
Spot monitor output of the VDM Digital Recorder to another monitor.

Note:
CAT5 cables are standard computer network cables that have four twisted pairs and are terminated with

RJ45 connectors. Because they are readily available, pre-terminated with connectors and can be patching
into existing structured cabling in many buildings, they are very easy to use. However, other high quality
twisted pair cables can be used – refer to section 3 to see which pins need to be connected.
