STEP FOUR: Configure your ICOM Radios
Consult your ICOM radio manual to discover how to configure the CI-V settings. Most ICOM
radios have three setting for the CI-V bus:
1. Baud Rate
2. Address
3. Transceive
4. CI-V with IC-731
Make sure the baud rate matches the baud rate as configured for the CI-V router. Recommend 9600
baud. Note the address. If there is more than one radio, make sure the addresses are different. The
address will be required when configuring PC client software.
Lastly, Transceive, should be ON.
Note: DO NOT SET THE RADIO BAUD RATE TO AUTO!
Note: The K9JM Router does not support the IC-731 CI-V frequency syntax
radios provide the option to operate "transceive" with the IC-731. This radio uses 4 bytes of
frequency data, as compared to the standard 5 bytes of frequency data. If your radio has a setting,
that is anything like "CI-V with IC-731", make sure this feature is turned off.
If you had to change any of these setting, you may need to re-sync your PW-1 with the radio.
STEP FIVE: Configure your PC Host Software
Unfortunately, there are nearly an infinite number of programs that run on the PC that can control
the CI-V bus. Fundamentally, the goal is to configure with the following parameters:
1. Baud Rate = Computer baud rate as configured on the CI-V router
2. RTS and DTR = OFF
3. Icom Address / Radio Type = Radio Configuration
4. If required, number of stop bits = 2, No Parity, No Flow Control
The Arduino board will reset whenever DTR is brought high. This is how the PC signals the
Arduino for a sofware download. If the DTR line can not be controlled, this can be defeated by
pulling up the Arduino "RESET" line with a 120 ohm resistor. This can be done easily by putting a
resistor between "5V" and "RESET" on the "POWER" pin head. If used the resistor MUST be
removed if a software upgrade is to be performed.
N1MM (Classic) Configuration:
N1MM configuration is done much like normal, except make sure the baud rate is set correctly and
that RTS and DTR are set to "Always OFF". N1MM does not require the pull up resistor on the
Arduino "RESET" line.
