Digiplex mode

Digiplex mode can be divided into two categories: standard Digiplex mode and hybrid Digiplex mode.
Standard Digiplex mode. 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.
Hybrid Digiplex mode. You can also operate a DVMRe/multiplexer when operating in a hybrid
Digiplex mode. This enables the DVMRe or multiplexer to provide multiscreen 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 DVMRes have dedicated monitors. If you are using Calibur
units, they must be connected to the keypad's RS-485 control signal; other brands must be
connected to the keypad's RS-422 control signal using a KTD-93 interface. When you press the
zone key, the keypad switches to zone mode operation (hybrid Digiplex mode), which enables it to
control the DVMRe/multiplexer (right display in Figure 3). 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 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 standard Digiplex mode of
operation.
Note: Camera control (PTZ) is disabled while in hybrid mode
