CAT (COMPUTER AIDED TRANSCEIVER)OPERATION
OVERVIEW
The CAT (Computer Aided Transceiver) System in the
FT-950 transceiver provides control of frequency, VFO,
memory, and other settings such as dual-channel memo-
ries and diversity reception using an external personal
computer. This allows multiple control operations to be
fully automated as single mouse clicks or keystroke op-
erations on the computer keyboard.
The FT-950 transceiver has a built-in level converter, al-
lowing direct 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 connec-
tion to the RS-232C (serial or COM port) connector on
your computer. 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 con-
nectors use a 9-pin rather than 25-pin configuration). If
your computer uses a custom connector, you may have to
construct the cable. In this case, refer to the technical docu-
mentation supplied with your computer for correct data
connection.
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.

CONTROL COMMAND
A computer control command is composed of an alpha-
betical command, various parameters, and the terminator
that signals the end of the control command.
Example: Set the VFO-A frequency to 14.250000 MHz.
FA 14250000 ;
KKK
Command Parameter Terminator
There is three for the FT-950 Command as shown below:
Set command: Set a particular condition
(to the FT-950)
Read command: Reads an answer
(from the FT-950)
Answer command: Transmits a condition
(from the FT-950)
For example, note the following in the case of the FA com-
mand (Set the VFO-A frequency):
To set the VFO-A frequency to 14.250000 MHz, the
following command is sent from the computer to the
transceiver:
“FA14250000;” (Set command)
To read the VFO-A frequency, the following command
is sent from the computer to the transceiver:
“FA;” (Read command)
When the Read command above has been sent, the
following command is returned to the computer:
“FA14250000;” (Answer command)
Alphabetical Commands
A command consists of 2 alphabetical characters.
You may use either lower or upper case characters. The
commands available for this transceiver are listed in the
“PC Control Command Tables” on the following pages.
Page"2
Parameters
Parameters are used to specify information necessary to
implement the desired command.
The parameters to be used for each command are prede-
termined. The number of digits assigned to each param-
eter is also predetermined. Refer to the “Control Com-
mand List” and the “Control Command Tables” to con-
figure the appropriate parameters.
When configuring parameters, be careful not to make the
following mistakes.
For example, when correct parameter is “IS0+1000” (IF
SHIFT):
IS01000;
Not enough parameters specified (No direction (+)
given for the IF shift)
IS0+100;
Not enough digits (Only three frequency digits
given)
IS0_+_1000;
Unnecessary characters between parameters
IS0+10000;
Too many digits (Five frequency digits given)
Note: If a particular parameter is not applicable to the FT-
950, the parameter digits should be filled using any char-
acter except the ASCII control codes (00 to 1Fh) and the
terminator (;).
Terminator
To signal the end of a command, it is necessary to use a
semicolon (;). The digit where this special character must
appear differs depending on the command used.
