Data Communication - XIEGU G90 Operation Manual

AVE "average" values gradually increase from 1 to 10. The effect on the display
is to smooth out rapid changes and provide a better representation of band
activity. This setting is a matter of personal taste. It can improve usability of the
spectrum display.

Data Communication

The G90/S supports all PC-generated amateur data communication modes and
remote control via computer software when a PC is linked to the radio. Only
simple wiring is needed to enable amateur data communications. The optional
DE-19 digital interface allows one USB cable connection to your PC to handle
both audio (data) traffic and serial control and is simpler than the process
defined below.
Version 1.79b02 firmware added the L-D and U-D (LSB-DATA and USB-DATA)
modes which switch the bandpass filter and ensures audio input and output via
the ACC socket only, disabling microphone audio.
The appropriate transmission mode should be selected for the data mode in
operation. The recommended modes for common data modes are as follows:
Data mode
PSK31
RTTY
FT4/8
When an amateur radio and a computer communicate using digital data
communication, the computer is used as a "modem" in that it converts the
signals to and from digital tones. While receiving, the audio from the signal
received is sent to the computer for demodulation. When transmitting, the audio
signal created by the computer is sent to the radio for transmission. Thus, the
computer's audio output level effects the TX power output and ALC readings.
The connections required are as follows:
Receiving: Received audio from the receiver→ computer audio IN
Transmitting: The computer-generated audio signal → radio TX Audio IN
Preparation:
For CAT command control of the radio from the PC you may use the supplied
USB->3.5mm plug cable or the optional DE-19 interface unit. Before using the
cable/unit for the first time, download and install the appropriate driver from the
Radioddity website. When you then plug the cable into your Windows PC it will
use this driver and not go off to search for an (incompatible) one from the Web.
Radio mode
USB/USB-D
LSB/LSB-D
USB/USB-D
* For other data modes, set the
radio mode to what is commonly
used for that data mode.
