The main function of the CI-V Transceive Switch is to allow any changes in IC-7300 status to be sent from the rig to the PC as unsolicited CI-V Responses. When the switch is set to ON, any changes in band, frequency, mode, filter, split setting or VFO A/B selection will immediately be sent to the PC. Note also that any changes in status are sent to external devices connected to the REMOTE port, using the broadcast address 00 hexadecimal.
