5 Video management
The back of the keyboard has a VIDEO connector to control the video devices. It is necessary to set up both the
keyboard and the controlled device correctly, since both the chosen communication protocols and speeds (baud
rate) should be the same.
If these parameters are set up incorrectly, communication between the devices is impossible.
5.1 Description of the display
If the keyboard is set to control an Everfocus DVR please read
§ 5.2.3 - Everfocus DVR Controlat page 26.
The DCJ keyboard display shows all the information required by the operator.
A typical display is as follows:




The four rows show, respectively:

: the last camera selected by the operator.
If an icon appears, and not a number, this means that specific functions have been requested:



: next camera expected by the sequence


: active monitor; all video operations are directed to this monitor
Message line (

in the example): alarm messages and the keys pressed are shown on this line.
The

symbol stands for the joystick position at rest and changes as the joystick moves.
5.2 Video: fundamental concepts
The DCJ keyboard allows two fundamental types of operations for controlling the video signal:

selection of a camera on the active monitor

starting a preset automatic sequence on the active monitor
All operations requested by the keyboard refer to the active monitor, which is always shown on the display.
Camera selection is subject to the setup of accepted cameras. If a camera is not accepted for the request, the
selection attempt is accompanied by an error message; see § 4.5.6 -
Warning message
, page 19.
Note that not all the functions are accepted by the different video devices (switchers and matrix). When a
requested function is not allowed for a video device, an error message warns the operator that it is impossible to
carry out the command.
5.2.1 Direct selection of a camera
