KTD-404
Controller Keypad
Overview
The KTD-404 is a keypad that controls Digiplex® system components. 
It can address and manage 512 PTZ (pan/tilt/zoom) receiver sites, 
operate a matrix switcher with 64 monitor outputs, and address and 
select views from as many as 64 multiplexers. In CyberDome® 
applications, the KTD-404 offers exceptional pan/tilt maneuverability 
with its variable speed joystick. In situations where two-way, voice 
communication is desired, an audio card can be added–establishing 
correspondence through its built-in speaker and 2.5 watt audio 
amplifier.
Outstanding Features
Access control allows the user to remotely open doors and gates. 
When call-ins occur, a built-in site annunciator sounds off, alerting the 
user when attention is needed. The KTD-404 is capable of stacking as 
many as 32 call-in requests in the order in which they were received.
Authorized personnel may program the KTD-404 and other Digiplex 
components through confidential access codes. Programmable 
components include CyberDomes, PTZ receivers, matrix video 
switchers, and alarm interfaces. All data is stored in nonvolatile 
memory.
The KTD-404’s comfortable, ergonomic keypad is housed in high 
impact, injection-molded plastic. It features large, easy-to-read 
buttons and a backlit, liquid crystal display (LCD). It communicates 
with Digiplex components through an RS422 signal over twisted-pair 
wire.
