113FT-857D Operating Manual
CAT OPERATION
The FT-857D’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-857D without (redundant) operator intervention.
The Optional CAT Interface Cable CT-62 is a connection cable for the FT-857D and your
computer. The CT-62 has a built-in level converter, allowing direct connection from the
rear panel CAT/LINEAR 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 variety
of personal computers, operating systems, and applications in use today.
The information presented in this section will allow the programmer to understand the
command structure and opcodes used in the FT-857D’s CAT System.
