3.4.5.1 Controlling telemetry receivers via the matrix
Set the protocol and baud rate for the Aux lines. When using Eneo PTH and Pelco D protocols it is also
necessary to select the receiver speed curve.
Speed curves for the Eneo PTH and Pelco D protocols
The Eneo PTH and Pelco D protocols are used by a considerable range of telemetry receivers, with quite different
properties in terms of speed and movement. If dome/P&T Head movement is not smooth (too fast at the least shift
of the joystick or considerable differences between adjacent speeds) we advise experimenting with each of the 4
possible speed curves and choosing the best.
3.4.5.1.1 Setting up the DCJ keyboard for telemetry control
• in the Communications\Telemetry Line X \Protocol menu select the protocol corresponding to the setting
for the matrix
• in the Communications\Telemetry Line X \Connector menu select Video
• in the Telemetry Lines menu assign all the receivers that are directly controlled by the matrix to line X
3.4.5.1.2 Setting up the DCT keyboard for telemetry control
For the choice of telemetry protocol, see the chapter on System data area / Communications / Telemetry
in the DCT keyboard manual.
To assign the telemetry lines see the chapter on System data area / Accepted values / Locally connected
cameras matrix and multiplexer / Cameras with matrix connection.
3.4.5.2 Controlling the video multiplexer via the matrix
Set the protocol and baud rate for the Aux lines,
3.4.5.2.1 Setting up the DCJ keyboard for controlling multiplexers
No settings are required for the keyboards: see the respective manual for a complete list of functions that
can be activated, depending on the type of protocol.

3.4.6 Open and closed periods
(Should matrix operation be differentiated between day and night?)
Sometimes matrix operation differs during the day (the period when the building under surveillance is
open) and at night (the period when the building closed). Holidays and holiday periods are considered
closed periods.
This time division makes it easy to set up the system to differentiate matrix behaviour in two time bands,
day (when the building is generally occupied by staff) and night (when the staff is not present and the
surveillance system is normally used by security personnel).
Many matrix functions (alarm acknowledgement, enabled keyboards, automatic sequences etc.) depend
on the time band. Should differentiated operation be unnecessary the menus can be simplified to make
system setup easier.
3.4.7 Date
The matrix is able to display the date and time and use these parameters to vary operation depending on
the period.
For the Date it is possible to make the following settings:
• the current date
• the format (international year/month/day, European day/month/year, American month/day/year); this
setting modifies the format of the date displayed in subsequent menus
• position and display (or not)
