(2) Custom Interface Cable: As noted above, the transceiver pods connect to the
StationPro controller unit using a 25–conductor computer cable. For most situations,
users will be able to use inexpensive “off the shelf” serial cables. However, for a few
situations, specifically when amateurs want to control two transceivers with a computer
that has only
one
serial port, while
also
operating SSB or AM, then it
may
be necessary
to prepare a custom interface cable. The purpose of the custom cable would be to prevent
coupling of computer noise from the RS-232 data into the transceivers’ microphone
circuits. Please refer to
Supplementary Assembly Manual: Preparing Custom
Transceiver Interface Cables
for a complete discussion of this topic, as well as
assembly instructions for making a custom interface cable if you should need one. Most
builders will not need to make a custom cable.
