OPERATION
OVERVIEW
The CAT (Computer Aided Transceiver) System in the
FT-450 provides control of frequency, VFO, memory, and
other settings such as dual-channel memories and diver-
sity reception using an external personal computer. This
allows multiple control operations to be fully automated
as single mouse clicks or keystroke operations on the com-
puter keyboard.
The FT-450 has a built-in level converter, allowing di-
rect connection from the rear-panel CAT jack to the serial
port of your computer without the need of any external
boxes. You will need a serial cable for connection to the
RS-232C (serial or COM port) connector on your com-
puter. Purchase a standard serial cable (not the so-called
“null modem” type), ensuring it has the correct gender
and number of pins (some serial COM port connectors
use a 9-pin rather than 25-pin configuration). If your com-
puter uses a custom connector, you may have to construct
the cable. In this case, refer to the technical documenta-
tion supplied with your computer for correct data connec-
tion.
Vertex Standard does not produce CAT System operating
software due to the wide variety of personal computers
and operating systems in use today. However, the infor-
mation provided in this chapter explains the serial data
structure and opcodes used by the CAT system. This in-
formation, along with the short programming examples,
is intended to help you start writing programs on your
own. As you become more familiar with CAT operation,
you can customize programs later on for your operating
needs and discover the true operating potential of this sys-
tem.
