If your MCP supports RTTY keying output, connect the output to pin 8 of the REMOTE connector. Connect the demodulation input line of the MCP to pin 5 of the DATA connector {page 78}. Also, connect the transmission control line of the MCP to pin 3 of the REMOTE terminal. Select "FSK" or "FSR" when you operate the RTTY mode. Note: Do not share a single power supply between the transceiver and the RTTY equipment.
