4.5 Auxiliary line
The EKR-8/4 / EKR-16/4 matrix is equipped with an auxiliary line AUX which can be used to control a video
multiplexer or telemetry line with ENEO, VIDEOTEC, MACRO or Pelco ‘D’ protocol (see paragraph 4.6).
It is possible to use the AUX line by setting the MACRO protocol in both the matrix and the control keyboards.
Hence, the keyboard allowing use of the AUX line is MTC-1. When the MACRO protocol is used for
communication between the keyboards and the matrix, the matrix takes care of converting the messages
destined for the AUX line into the appropriate protocol (that of the controlled device).
4.5.1 Control key board configuration
4.5.1.1 MTC-1 Keybo ard
The MTC-1 keyboard is able to control both telemetry receivers and video multiplexers. Because the keyboard
is so flexibles, it should be configured very carefully, following the instructions in its user’s manuals. At the
keyboard level, configure the video line for the MACRO protocol.

After setting the AUX line for the matrix, depending on the type of multiplexer used (see OSM programming for
the AUX line at
Coax and Aux Line Transmission
Submenu), the matrix will take care of converting the
messages destined for the AUX line into the appropriate protocol. See the keyboard and multiplexer manuals for
instructions on using these devices.
4.5.3 Telemetry r eceiver control and domes
Only receivers (or domes) with ENEO, VIDEOTEC, MACRO or Pelco ‘D’ protocol (see paragraph 4.6) can be
controlled. After setting the AUX line for the matrix, depending on the type of protocol used (see OSM
programming for the AUX line at
Coax and Aux Line Transmission
Submenu), the matrix will take care of
converting the messages destined for the AUX line into the appropriate protocol. See the keyboard and
multiplexer manuals for instructions on using these devices.
