PC CONTROL COMMAND REFERENCE GUIDE
ABOUT THIS REFERENCE GUIDE
All descriptions in this reference guide are for the
user’s convenience. JVC KENWOOD Corporation
does not support nor warrant the applicability of this
documentation in any way.
CONNECTING TO A PC
You can connect the TS-590S/ TS-590SG transceiver
to a PC COM port using a traditional RS-232C
connector, or to a USB port using a USB 2.0 (AB type)
cable.
If using the COM port or USB, through the transceiver
menu, select a baud rate for communications between
the PC and the transceiver.
■ Using a RS-232C Straight Cable
Directly connect the RS-232C straight cable
between the COM port of the PC and the COM
terminal of the transceiver.
■ Using a USB Cable
When using a USB cable, you must first pre-install
a virtual COM port driver on the PC. Then, connect
the USB cable A-connector to the USB port of the
PC and the B-connector the USB terminal of the
transceiver.
Download the driver from the following URL.

Note: No warranty for the operation is granted when
connecting through a USB hub.

AI (AUTO INFORMATION) FUNCTION
The AI (Auto Information) function automatically outputs
contents of commands whenever various states of the
transceiver changes.
For example, the frequency information of the main band
is automatically output to the PC with the FA command
when you change the operating frequency of the main
band. It is not necessary to first send a read command
from the PC. Besides the frequency of the main band,
almost all changes of state of the transceiver are
automatically output with each command.
Using this function, you can see the state of the
transceiver on a PC in real time. This is useful when
making an application using log management software.
Turn this function on using the AI command (the initial
state is OFF).
PC CONTROL COMMANDS
A PC 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 ;
Alphabetical command
Parameters
Terminator
Commands can be classified as shown below:
Computer
control
commands
Input command
(input to the
transceiver)
Set command
(sets a particular
condition)
Read command
(reads an answer)
Output command
(from the
transceiver)
Answer command
(transmits a
condition)
For example, note the following in the case of the
above FA command (Frequency of VFO A):
• Tosetthefrequencyto7MHz,thefollowing
command is sent from the PC to the transceiver:
“FA00007000000;” (Set command)
• ToreadthefrequencyofVFOA,thefollowing
command is sent from the PC to the transceiver:
“FA;” (Read command)
• WhentheReadcommandabovehasbeensent,
the following command is returned to the PC:
“FA00007000000;” (Answer command)
■ 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.
