CI-V Scout - A Quick Tutorial
This article will give a very short tutorial on how to use the CI-V Scout
command builder to send a command to a CI-V capable radio. The command I
will use for this tutorial is the "set operating frequency" command since
some variant of it is probably available in any CI-V capable radio.
The radio I am using for this tutorial is an ICOM IC-7300. The frequency data
format may be different for your radio.
The first thing you must do when you run CI-V Scout is to set the serial
port parameters for connecting to your radio. This will depend on
your particular hardware configuration. At a minimum you will need
to select the port and baud rate. The COM port must be the serial port
that your computer uses to communicate with your radio. The baud rate must match the
baud rate set in your radio settings.
Once you have entered all of the appropriate settings press the
"Start" button to initiate serial communications with your radio. If your
radio's CI-V communications have Transceive enabled, turning the main tuning
knob should cause data to appear in the lower section of the CI-V Scout
Once you have confirmed that communications with the radio are working
you can build the command to set the operating frequency. For the source address
we will use the default address of E0. The destination address must be the
CI-V address of your radio. In the case of the IC7300 the default address
is 94, so I enter that for the destination address. If your radio is not an ICOM IC7300
the address will be different. You will need to check with the documentation for your radio
or check the settings in the radio's menu to determine the correct address.
According to the
documentation for the IC7300 the command to set the operating frequency has a value of
05, so I enter that value for the command. In this case there is no sub-command
so that field must be left blank. The data field requires a bit more
The IC7300 documentation shows the format for operating frequency as
IC7300 Operating Frequency Format
|10 Hz digit
|1 Hz digit
|1 KHz digit
|100 Hz digit
|100 KHz digit
|10 KHz digit
|10 MHz digit
|1 MHz digit
|1000 MHz digit
|100 MHz digit
Note: Your radio may use a different format for representing the
frequency. Check the documentation for your radio model for more
If we want to set the frequency to 14.175 MHz, we would need to send the
data sequence 00 50 17 14 00. You will need to enter those values in the
data builder in that specific order for the radio to be able to process
them. Once you have entered all of that your window should look like this:
Now press the send button. If everything is entered correctly and the
radio and computer are communicating properly the operating frequency will change to 14.175 MHz.
Congratulations on building the command and have fun.
