The KTD-405 can be programmed to operate in either of two modes: standard Digiplex
®
or zone
(DVMRe/multiplexer/PTZ control). See
Appendix C. Sample System Configurations
.
Be aware that the addressing between domes and multiplexers is offset. When setting up and controlling
your cameras in zone mode, refer to Appendix A (
Zone Receiver Site Addressing
).

In
standard Digiplex mode
, the system’s main switching device is a standard matrix switcher. The keypad
can address and control 512 PTZ receiver sites, operate a matrix switcher with 64 monitor outputs, address
and select views from 32 multiplexers, operate up to 32 recorders, and manage access control points.
You can also operate a DVMRe/multiplexer when operating in a
hybrid Digiplex mode
. This enables the
DVMRe or multiplexer to provide multi-screen views by connecting the output of the unit to an input on the
matrix switcher. Digiplex mode (standard or hybrid) does not require that the DVMRe’s have dedicated
monitors. If you are using Calibur
TM
units, they must be connected to the keypad’s RS485 control signal;
other brands must be connected to the keypad’s RS422 control signal using a KTD-93 interface. When you
press the zone key, the keypad switches to the zone-mode style of operation (hybrid Digiplex mode), which
enables it to control the DVMRe/multiplexer. See Figure 4. If the zone is assigned to a camera input on the
matrix switcher (done in programming), when you select the zone, the keypad sends a command to the
matrix switcher to call up the assigned input on the active monitor. While in the hybrid Digiplex mode, key
functions are the same as those used during normal zone mode operation, except the
esc
key, which
returns the keypad to the standard Digiplex mode of operation.
Note:
Camera control (PTZ) is disabled while in the hybrid zone mode.

A zone is a remote switching device (multiplexer or DVMRe) that serves a group of cameras. A system
can be divided into as many as 32 zones, and each zone can have from 1 to 32 cameras.
The outputs from the zone’s switching device connect to dedicated monitors directly. Each zone is
assigned a device type (multiplexer or DVMRe) and a size (1 to 32 cameras) and can be assigned a
15-character name.
To call up a camera in a zone you must know the zone number (or name) and the camera number. See
Figure 5 and refer to Appendix A (
Zone Receiver Site Addressing
).
