14 CONNECTING PERIPHERAL EQUIPMENT
RTTY OPERATION
Use the REMOTE and DATA connectors to interface with your MCP. 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. Keep as wide a separation as possible between the transceiver and the RTTY equipment to reduce

Power supply for the
HF/ 50 MHz LINEAR AMPLIFIER
Connect an external transmission power amplifier to the REMOTE connector (1 male,
The TX/ RX relay response time is 10 ms when you have selected CW Full
Note:
◆The TX/ RX control method differs, depending on external amplifier models. Some amplifiers enter the TX mode when the control terminal is grounded. For those amplifiers, connect pin 2 of the REMOTE connector to the GND terminal of the amplifier and connect pin 4 of the connector to the control terminal of the amplifier.
◆The mini DIN connectors (DATA and REMOTE connectors) look alike. Confirm the number of pins before plugging into the transceiver connectors. The REMOTE connector is an
Linear Amp.
