Connect to a computer for amateur radio data communication
The G90 transceiver can be connected to a computer to perform various data communication with the corresponding computer
software.
Operation connection method:
1. Go to the Xiegu website and download the data cable driver. Install it on your PC. Then Insert the provided data cable into the
(communication) port on the left side of the machine head and then plug it into the computer's USB port. This provides your CAT
control line.
2. Connect the G90's audio output signal (AF_OUT pin of the ACC port) to the computer's audio input port. The #6 item of the system
menu can adjust the volume of the output signal.
3. Connect the audio output signal of the computer to the audio input port of the G90 (AF_IN pin of the ACC port). The #5 item of the
system menu can adjust the volume of the input signal. (*see below)
4. Set the G90 to line input mode (see "Line Input, Output" setting).
5. Set your USB port's speed and bits to match the G90 using the Device Manager.
6. Set your PC software (Fldigi, WSJTX etc) to match the same bits and speed.
*Please use good grounding on the radio and PC. It's good practice to install a clamp-on ferrite choke to the data and audio cables
and install it as close as possible to the radio. The level of the output signal of the radio and the level of the output signal of the
computer should be adjusted to avoid overloading. For TX audio in, a good method is to set the radio to 20W output power and then
adjust your PC's audio output level for just under 10 watts out (mid-scale). Most digital modes are 100% duty-cycle. This method will
avoid over-heating the final transistors and provide the cleanest digital signal. The finals are thermally protected, but use good
operating procedure shown above.
