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 noise-pickup by the transceiver.

HF/ 50 MHz LINEAR AMPLIFIER
Connect an external transmission power amplifier to the REMOTE connector (1 male, 8-pin mini DIN connector
(E57-0405-XX) is supplied). Switch ON the linear amplifier control relay via Menu Nos. 28 (HF) and 29 (50 MHz).
Select “2” or “3” if you use the internal relay to control the linear amplifier status.
The TX/ RX relay response time is 10 ms when you have selected CW Full Break-in and 25 ms when you have
selected CW Semi Break-in.
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 8-pin mini DIN connector and the
DATA
connector is a 6-pin mini DIN connector.
