5 Video ma nagement
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 Descriptio n of the display
If the keyboard is set to control an Everfocus DVR please read § 5.2.3 - Everfocus DVR Controlat page 26.
The EKR-KB1 keyboard display shows all the information required by the operator.

5.2 Video: fun damental concepts
The EKR-KB1 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.
