PC Data Comm. Connections

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.

Computer Control Instructions

The G90 uses the standard CIV instruction set. You can use the standard commands
of this instruction set to remotely control the transceiver. It can also be used to
configure the control instructions of other software to control the G90. To get
going rapidly, you can use the configuration file for another radio that uses the
standard instruction set. Check the Xiegu forum for the latest suggested compatible
radio configuration files to try. (IE: IC-817 / IC-7000)

Band/Voltage Output for Ext. Amp

The G90's ACC port provides a band data voltage output for each band. The band
data can control peripheral to automatically switch the band or share the band
information with other devices. (IE: the XPA-125 amp)
Band Voltage
1.8MHz 230mV
3.5MHz 460mV
5.0MHz 690mV
