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.
