Telemetry Transmitter Pin 9 is normally a single bit input that turns on or off the RF output power. This pin is pulled high internally. Refer to the RF and RZ commands in Table 19. Pin 10 is the ground connection to the DC power source. This pin is connected internally to pin 1, pin 8, and pins 11 and 12, making the transmitter the central ground connection for the control device, the data/clock source, and power.

Telemetry Transmitter While this command incorporates the functionality of nine (9) or more commands, those commands are still usable. For example, if the unit has the -VR option then the BT command can still be used by itself to switch between TTL and RS-422 inputs for clock and data.
Telemetry Transmitter With the LD6 option, use LD 0 or 1 to disable or enable LDPC, then use 0-5 to indicate the desired LDPC code. A space is required between the disable/enable code and the desired LDPC selection, as shown in the examples.
Examples are auto-carrier (-AC option), clock free (-CF option) and recall-holdoff (-RH option). If the procedure below does not demonstrate the working RF output on the transmitter, please contact Quasonix technical support for further help in resolving the issue.
