Rear Panel
The rear panel of the Z-817H features five connectors.
•
ANT connector: Connect a 50-ohm coax antenna feedline to this standard SO-239
connector.
•
GND connector (wing nut): Connect to antenna system ground.
•
TX connector: Connect a 50-ohm coax jumper cable from this standard SO-239 connector
to the ANT (OUTPUT) jack on the back of the amplifier. If running barefoot (no amplifier),
connect to the FT-817’s ANT jack.
•
PC connector: This 8-pin mini-DIN connector connects to a personal computer via CT-62
compatible PC interface cable (not included). Use of this port is optional; it is provided for
those hams who would like to control their radio via computer. This is a pass-thru port to the
RADIO port, and is switched under software control by the Z-817H’s microprocessor. The
firmware of the Z-817H has been written such that this will seem transparent to the user -- if
using CAT to control your FT-817, just plug the PC’s CAT cable into this port instead of the
CAT jack on the back of the transceiver.
•
RADIO connector: This 8-pin mini-DIN connector is for connection to the FT-817’s ACC
jack. The Z-817H controls the PTT, power level, and operating mode via CAT commands sent
to the transceiver. The Z-817H also reads the operating frequency directly from the transceiver
so that it knows where to store tuning memory data.
