Computer control instruction
G1M uses the standard CIV instruction set. You can use the standard
instructions of this instruction set to remotely control the transceiver.
You can also configure the control instructions of other software to control
the G1M.
Band voltage data
G1M's ACC port provides band data for four bands. The band data can control the peripheral device to automatically switch the band or
share the band information with other devices.
Band Voltage Band Voltage Band Voltage Band Voltage
3.5MHz 460mV 7MHz 920mV 14MHz 1380mV 21MHz 1840mV
In the other frequency bands except the above four amateur bands, the band voltage is uniformly outputted at a high level, 5V.
