RANDOM PAN – Rx300
The Rx300 telemetry receivers provide a random pan feature. During Random Pan operation, the camera is
randomly panned left or right for a random duration, paused for a random duration and then panned again.
This adds the affect that the camera is manually controlled. During random pan, the camera can be tilted to
the desired angle using the up/down buttons. Random pan is disabled by pressing either the pan right or
the pan left button.
TWISTED PAIR OUTPUT
The TWISTED PAIR output sends telemetry signals from the transmitter to the receiver. A video cable
connection is still required. The normal reason for using a twisted pair option is to connect to a non-cable
transmission system, fibre, microwave etc.
The twisted pair output option provides a 20mA compatible output. 1200 baud 8 data bits 1 stop bit, Even
parity.

If RF/Laser/Microwave etc. used
to extend link, 20mA input may

Section of Rx
Simple twisted pair telemetry when not practical to use up-
A coaxial cable is required to carry the video from the camera to the control
If the Rx is over driven from the RF/
Laser/Microwave equipment, the error
LED will light. Connecting a 470R
resistor across Pin 1/2 cures
