User Manual
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 (Figure 1) or be merged using KTD-312 signal mergers (Figure 2) before
being routed to the rest of the components in the system.

Installation
To install a KTD-400 keypad, you will need to set the DIP switches, mount the unit (KTD-300R only), and
wire the device.
CAUTION: Do not connect power to the unit before all installation steps have been completed. Do not connect directly to
a telecommunication network.

User Manual
Mounting the KTD-300R
The KTD-300R is designed to fit into a standard EIA 19-inch rack and uses one unit (1.75 in.) of rack space.
Mount the unit using the four holes in its front panel and hardware provided from the rack manufacturer.
Wiring connections
The KTD-400 comes with a 6 ft. (1.8 m) cable that attaches to a modular phone box (Figure 4). All external
connections are made in the phone box. KTD-300R connections are made to the removable terminal strip
located on the back of the unit (Figure 5 on page 4). Wiring the KTD-400 and 300R to control a standard
Digiplex system involves connecting the RS-422 input cable (if used), the RS-422 output cable, and the
12 VDC wall transformer.
Note: Figure 4, Figure5, and Figure6 on page 5 show connection points for an RS-422 input cable and an RS-422 output
cable. Do not confuse the two. The input is used only if other keypads, alarm chassis, or time/date generators are
located ahead of the unit that is being wired.

Wiring the KTD-300R to control a KTS-41A system involves connecting the RS-422 input cable (if used), the
RS-422 output cable (if used), the DTMF output cable (to the KTS-41A), and the 12 VDC wall transformer
(Figure 6).

Power-up
After you make all the connections, the KTD-400 or KTD-300R will be ready for operation. Plug the 12 VDC
wall transformer into a power outlet. The LCD window will briefly display keypad setting information
(Figure 7 on page 6), then it will enter the operating mode.
