Computer Control Commands - Kenwood TS-590S Reference Manual

COMPUTER CONTROL COMMANDS

A computer control command is composed of
a 2 letter alphabetical command name, a set of
parameters, and the terminator that signals the end of
the command.
Example: Command to set VFO A to 7 MHz
FA 00007000000
Parameters
Alphabetical command
Commands can be classified as shown below:
Input command
(input to the
transceiver)
Computer
control
commands
Output command
(from the
transceiver)
For example, note the following in the case of the
above FA command (Frequency of VFO A):
• To set the frequency to 7 MHz, the following
command is sent from the computer to the
transceiver:
"FA00007000000;"
• To read the frequency of VFO A, the following
command is sent from the computer to the
transceiver:
"FA;"
• When the Read command above has been sent,
the following command is returned to the computer:
"FA00007000000;"
Note:
Do not use the control characters 00 to 1Fh since they are
◆
either ignored or cause a "?" answer.
Program execution may be delayed while turning the Tuning
◆
control rapidly.
Receive data is not processed if the frequency is entered
◆
from the keypad.

Command
■
A command consists of 2 or 3 characters. You may
use either lower or upper case characters. The
commands available for this transceiver are listed
in the PC Control Command Tables, beginning on
page 3.
Parameters
■
Parameters are used to specify information
necessary to implement the desired command.
The parameters to be used for each command are
predetermined. The number of digits assigned
to each parameter is also predetermined. Refer
to the PC Control Command Tables {page 3} to
configure the appropriate parameters.
When configuring parameters, be careful not to
make the following mistakes.
Correct parameter example: "IS+1000;"
IS1000; Not enough parameters specified
(No direction given for the IF shift)
IS+100; Not enough digits
(Only three frequency digits given)
IS_+_1000; Unnecessary characters (spaces)
between parameters
IS+10000; Too many digits
(Five frequency digits given)
Note: If a particular parameter is not applicable to this
transceiver, the parameter digits should be filled using any
character 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.
Error Messages
■
In addition to the Answer command, the transceiver
can send the error messages listed below.
Error
Message
• Command syntax was incorrect.
• Command was not executed due to
the current status of the transceiver
(even though the command syntax
?;
was correct).
Note: Occasionally, this message may not
appear due to microprocessor transients in
the transceiver.
A communication error occurred, such
E; as an overrun or framing error during a
serial data transmission.
Receive data was sent but processing
O;
was not completed.
