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.

ON
MONITOR
DIGITAL RECORDER
VK-1 KEYBOARD

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.

POWER SUPPLY
In this configuration, with video being transmitter via twisted pair, you will need an adapter PCB (order code:
T25A) and a video balun (order code: VX-2)
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. In this
case, only one twisted pair core is actually used (for the data), and cable runs up to 1000m are possible.
To make sure the VK-1 keyboard only controls the spot monitor, set the configuration switch on the
underside of the unit ON, as shown in this diagram:

1.3 Connecting more than one keyboard
Another keyboard can simply be added by connecting it to the “Loop In” RJ45 connector on the master VK-1
keyboard.

Note that the first monitor should be un-terminated (set to high impedance), and the second monitor should

1.4 Connecting to more than one Digital Recorder
Digital Recorders can be daisy-chained as illustrated in the diagram below. This configuration allows one or
more keyboards to control multiple Digital Recorders. It also ensures that the clocks of the Digital Recorders
are kept exactly in step (within a second). If the time and date needs adjusting, adjust clock of the “Master”.
The “Slave” will be updated automatically (every minute).

slide switch on the rear of the VDM. Do not turn both termination switches ON.

2.1 Configuring VDM Digital Recorder
The keyboard port of the VDM Digital recorder must be enabled (usually as a clock master) in order to
accept command from a keyboard. An Engineer menu option is provided for this purpose. Refer to the VDM
manual for details.
2.2 Full Control
The switch on the underside of the unit must be “OFF” in order to enable the VK-1 to have full control of a
VDM recorder, subject to password access restrictions (refer to section 2.3 for diagram).
The keys have the same layout and function as the keys build into the VDM recorder itself. Refer to the VDM
operating manual for details.
2.3 Spot Monitor Only Control
The keyboard may be configured to provide control of the spot monitor only. The switch on the underside of
the unit should be “ON” to select this option (refer to section 2.3 for diagram). In this mode, the only keys
that have a function are the cameras keys 1,2,3…16 which directly select camera for display on a spot
monitor. The spot monitor auto-sequencing key is the only other key that has a function in this mode.
2.4 Addressing more than one VDM Digital Recorder
If more than one VDM Digital Recorder is connected to a single keyboard, each one must be configured with
a different address (01, 02, 03 etc).
Before a particular VDM Digital Recorder can be controlled by the VK-1, it must first be selected. To do this,
simultaneously press the ALT key, the
Í
(left arrow) key and one of the camera select keys
1,2,3,4,5,6,7 or 8.
The VDM recorder which has the address corresponding to the camera key pressed will be selected and
ready to be controlled. The address remains until another one is selected or if power has been removed
from the keyboard, in which case it will default to address 01.

The RS232 input may be used instead of the RS485 “Loop-In” where control from a computer is required.
The software “VDM Remote” runs on a PC and allows one or more Digital Recorders to be controlled via a
mouse and virtual keyboard on the PC. If display is also required on the PC’s monitor, a USB-to-video
converter may be connected the VK-1’s video output BNC (order code: VDM/USB).
