Operation Manual

70 FT-817ND Operating Manual
The FT-817ND’s CAT System allows the transceiver to be controlled by a personal com-
puter. This allows multiple control operations to be fully automated as a single mouse click,
or it allows a third-party software package (such as contest logging software) to communi-
cate with the FT-817ND without (redundant) operator intervention.
The Optional CAT Interface Cable CT-62 is a connection cable for the FT-817ND and
your computer. The CT-62 has a built-in level converter, allowing direct connection from
the rear panel ACC jack to the serial port of your computer, without the need for an external
RS-232C level converter box.
Vertex Standard does not produce CAT System operating software, due to the wide vari-
ety of personal computers, operating systems, and applications in use today. However, the
FT-817ND (and other Yaesu products) are widely supported by third-party software pack-
ages, and we recommend that you contact your dealer for advice, or check advertisements
in amateur radio journals. Most software vendors also have Home Pages on the World Wide
Web which contain a wealth of information on the features and radio support for their
software packages.
The information presented in this section will allow the programmer to understand the
command structure and opcodes used in the FT-817ND’s CAT System.
