The FT-857's
System allows the transceiver to be controlled by a personal computer.
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 communicate
with the FT-857 without (redundant) operator intervention.
The Optional CAT Interface Cable CT-62 is a connection cable for the FT-857 and your
computer. The CT-62 has a built-in level converter, allowing direct connection from the rear
CAT
/LINEAR jack to the serial port of your computer, without the need for an exter-
panel
nal RS-232C level converter box.
CAT
Vertex Standard does not produce System operating software, due to the wide variety
