Interface Of Packet Tncs; Reset - Vertex Standard VX-110 Operating Manual

Interface of Packet TNCs & Reset
The VX-110 may be used for Packet operation, using the optional CT-44 microphone
adapter (available from your Yaesu dealer) for easy interconnection to commonly-avail-
able connectors wired to your TNC. You may also build your own cable using a four-
conductor miniature phone plug, per the diagram below.
The audio level from the receiver to
the TNC may be adjusted by using the
VOL knob, as with voice operation.
The input level to the VX-110 from the
TNC should be adjusted at the TNC
side; the optimum input voltage is ap-
proximately 5 mV at 2 k-Ohms.
Be sure to turn the transceiver and TNC
off before connecting the cables, so as
to prevent voltage spikes from possi-
bly damaging your transceiver. Also,
be certain to turn off the Receiver Bat-
tery Saver, if activated (see page 10).
In the event that erratic, unpredictable transceiver operation is encountered, it is possible
that the microprocessor has sustained a static burst or other condition that has caused
corruption of some of its data. If this should happen, resetting of the microprocessor should
clear up the problem. Here is the procedure for resetting the microprocessor (this will
restore all factory defaults, and will erase all memories):
Turn the radio off.
Press and hold the [ PTT ] and [ LAMP ] key while turning the radio on.
Rotate the DIAL to select "
Press the [ F ] key momentarily to initialize the radio.
This "Reset" procedure restores the Menu ("Set mode") settins to their factory defaults,
without affecting your regular memories.
Turn the radio off.
Press and hold the [ PTT ] and [ LAMP ] key while turning the radio on.
Rotate the DIAL to select "
Press the [ F ] key momentarily to initialize the Set mode.
