Controlling Via a Control System
You can control the receiver and/or a connected sink device via a control system that is
connected to the CONTROL port on the
KIT-400T
.
Controlling the Receiver
To control the receiver via a control system at the transmitter, connect the control system to
the CONTROL RS-232 port
and send a device protocol command via the TUNNEL-CTRL
command. For example, to open the relay contacts (RELAY-STATE 1,0), send the #TUNNEL-
CTRL 1,1,”RELAY-STATE 1,0”<CR> command from the control system, via HDBT to the
KIT-400R
.

Controlling a Sink Device Connected to the Receiver
For applications where the control system controls a device at the
KIT-400R
sink, connect the
control system to the CONTROL RS-232 port
and send a device protocol command via
the TUNNEL-CTRL command.
For example, to turn the display off (DISPLAY OFF), send the #TUNNEL-CTRL
1,1,”TUNNEL-232 ‘DISPLAY OFF’9600”<CR> command from the control system, via HDBT
to the
KIT-400R
.
