ntroduction
This manual covers installation and operation instructions for a KTD-404 series keypad.
NOTE: This product was originally called the KTD-304. It has been updated to the KTD-404;
although the look of the KTD-404 has been modified, the functionality of both versions
remains the same. All instructions in this manual referring to the KTD-404 are also applicable
to the KTD-304 version.
Designed for use in a DIGIPLEX system, the KTD-404 can address and control 512 Pan/
Tilt/Zoom receiver sites, operate a matrix switcher with 64 monitor outputs, and address and
select views from as many as 64 multiplexers. The KTD-404 series is also available with
an audio option (designated KTD-404A) or rack-mounted (KTD-304RA) in which the
keypad contains a 2.5 watt audio amplifier for 2-way voice communication. To operate and
control multiplexers, a KTD-93 is required to interface with each device in a Digiplex system.
A DIGIPLEX system's RS422 control signal originates from the controller keypad located
at the head end 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. Figures 1-4 show typical system configurations.
