14 CONNECTING PERIPHERAL EQUIPMENT
ANTENNA TUNER
Use the ANT 1 and
AT
connectors to connect an AT-300 external antenna tuner. If you connect the external
antenna tuner to the ANT 2 connector, it will not function.
Note:
When the AT-300 is used with the TS-480HX transceiver, the TX output power is automatically reduced to 100 W (AM mode: 25 W).
Also, the AT-300 cannot be used for 50 MHz operation.

MCP AND TNC
Use the
DATA
connector to connect the AF input/ output lines from a Terminal Node Controller (TNC) for Packet
operation, a Multimode Communications Processor (MCP) for operation on AFSK, Packet, PacTOR, AMTOR,
G-TOR
TM
, PSK31, or FAX, or a Clover interface. Also use the
DATA
connector to connect SSTV and phone patch
equipment (1 male, 6-pin mini DIN connector (E57-0404-XX) is supplied).
•
Connect the TNC or MCP to the
DATA
connector using a cable equipped with a 6-pin mini DIN plug.
•
Connecting the TNC or MCP to a personal computer or dumb terminal requires an RS-232C cable.
•
Select LSB or USB mode (it depends on the communication mode) when you operate the MCP/ TNC.
Note:
◆
Do not share a single power supply between the transceiver and the TNC or MCP. Keep as wide a separation as possible between the
transceiver and the computer to reduce noise-pickup by the transceiver.
◆
The mini DIN connectors (
REMOTE
and
DATA
connectors) look alike. Confirm the number of pins before plugging into the transceiver
connectors. The
DATA
connector is a 6-pin mini DIN connector and the
REMOTE
connector is an 8-pin mini DIN connector.
