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 PTZ receiver sites, operate a matrix switcher with 128
monitor outputs, address and select views from 32 multiplexers, operate up to 32 recorders, and manage
access control points.
Note: The keypad can address and control 1599 PTZ's using the RS485 and 1023 PTZ's using RS422. Independent
permissions can be set for 1023 PTZ cameras.
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
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
