INSTALLATION
The Z-817 tuner is designed for indoor operation only; it is not water resistant. If you use it
outdoors (Field Day, for example), you must protect it from the rain. The Z-817 is designed for use
with coax-fed antennas. If use with longwires or ladder-line-fed antennas is desired, an external
balun is required. The LDG RBA-4:1 or RBA-1:1 is ideal, depending on the antenna and
transmission line used.
Always turn your radio off
before plugging or unplugging anything. The radio may be damaged
if cables are connected or disconnected while the power is on.
Connect the rear antenna jack on the FT-817 to the TX jack on the back of the Z-817, using a
50 ohm coax cable rated 20 watts or greater.
FT-817 Installation
Connect the supplied radio interface cable to the mini-DIN 8-pin jack on the rear of the Z-817,
marked “Radio”. Connect the other end of this cable to the “ACC” port on the rear of the FT-817.
On the FT-817, press and hold the “F” button on the front panel for one second, to enter the
extended menu. Rotate the SEL knob until menu # 14, “CAT RATE” is showing. Rotate the tuning
dial until “38400” is displayed. Now press and hold the “F” button again to resume normal
operation.
If it is desired to operate the FT-817 via computer control, connect the Yaesu CT-62 CAT
interface cable to the Z-817 port labelled “Computer”. The Z-817 will automatically feed through
any CAT commands coming in over this port to the FT-817 and vice versa. Note that any software
used to control the FT-817 will have to be set for 38,400 baud while connected through the Z-817.
Non-FT-817 Installation
As above, but do not connect the supplied CAT cable, and no radio menu settings are required.
