Product overview
The KTD-400 Controller Keypad is designed for use in a Digiplex system. The KTD-400 can address and
control 512 pan/tilt/zoom (PTZ) receiver sites, operate a matrix switcher with 64 monitor outputs, and address/
select views from as many as 64 multiplexers and VCRs. Several modes of multiplexers are supported.
Note:
For CyberDome control with the KTD-400, pan/tilt operation is limited to three speeds. To operate and control
multiplexers and VCRs, you must have a KTD-93 auxiliary device driver attached to each device in a Digiplex system.
Controller keypad placement
A Digiplex system’s RS-422 control signal originates from the controller keypad located at the head of the
system and travels down line via twisted-pair cable. When more than one controller keypad is used, the signal
must loop through each keypad (
) or be merged using KTD-312 signal mergers (
) before
being routed to the rest of the components in the system.
