KTD-405/405A/405-2D overview

Operating modes

The KTD-405 can be programmed to operate in two modes: standard Digiplex

or zone (DVMR/multiplexer/

PTZ control). (See Appendix A, Sample configurations and charts for layout samples of these modes.)

Note: Be aware that the addressing between domes and multiplexers is offset. When setting up and controlling your cameras in

zone mode, refer to Receiver site addressing on page 65.

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

™

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
