DIAGNOSTIC AIDS

A 7 segment LED display is mounted on the top PCB this gives system status information. The meanings
of the values are as follows:
The value Description
. All OK
L. Sending a pan left to the dome
r. Sending a pan right to the dome
.u Sending a tilt up to the dome
.d Sending a down up to the dome
*NB Not all transmitters provide a constant telemetry signal, therefore seeing error 9.1 until telemetry is sent is
normal.
This error will be seen if using a CTI/1, TX1500 and will also occur if the camera is not selected on a TX1000.
During the operation of the unit you will see a red flashing dot in the middle of the 7 segment LED display this
means the unit is working.
The Rx10X is designed to auto-tune and compensate for any discrepancies in the transmitted telemetry
signal; there are no further adjustments that need to be made.
The Rx10X has an in built facility that enables you to test the communications between the Rx10X& the
dome. This is done by pressing SW1 and the dome will pan left or press SW3 and the dome will pan right,
on releasing the button the dome will stop.

VIDEO LAUNCH AMPLIFIER AND CABLE LENGTH COMPENSATION
The interface features a video launch amplifier with two variable controls situated close to the BNC
connectors: Lift and Gain. These are pre-adjusted for a cable distance of 500m of CT125, and are
adjustable to compensate for video detail or signal losses if and when longer or shorter cable lengths are
used to connect the telemetry transmitter to the interface.

Default position adjusted for 500M of CT125.
For shorter cable lengths, turn the GAIN control anti-clockwise until 1V p-p is present at the telemetry
transmitter. For longer cable lengths, turn the GAIN control clockwise until 1V p-p is present at the telemetry
transmitter.
