Communication problem - COM error
#1
For communication errors try this:

- Install IC7300BKT latest version from http://www.maniaradio.it.

- check these settings in Icom IC-7300 Set-Mode->Connectors->CI-V:
CI-V Baud Rate = Auto ( in some cases you need to select the speed set in the program ex. 19200 or 9600 )
CI-V Address = 88h
CI-V Transceive = OFF

- Install USB drivers Icom (download from: http://www.icom.co.jp/world/support/down...index.html)

- From SerialPort drop-down list select the COM port with the description "SILICON LABS..."

- try to change Serial Port Mode from MODE 1 to MODE 2

- try to switch ON/OFF the RTS and DTR signal

- try to change BAUD speed

- Verify that there are not running other programs that use the same COM port
