Up-The-Coax telemetry control
Commands to control the position of the dome can be
transmitted up the same coax cable used to transmit
the video signal to the recorder station. Different
controllers require different protocols and two switches
are provided to select the desired protocol.
The switches are colour coded, blue and yellow and
located inside the dome camera housing. To access
them rotate the unit until the switch is available through
the access hole at the top of the case
(see Fig.6)
.
Configure the switches for the controller being used as
shown in table below.
The switches are factory set to 253 Den Panel.
