The OPC-478 cable interconnects your IC-R5, your Icom IC-A22E and your Icom IC-A3 to your PC. The OPC-478 cable has a 9-pin D-sub connector on one end, and a 3,5 mm jack plug on the other. The D-sub connector connects to a 9-pin serial port on your PC whereas the jack plug goes (originally) into the earphone socket of your IC-R10. Inside the D-sub connector a small circuit is built that converts the TTL-level data on the IC-R10's side to the RS232C-levels on the PC's side.

• Please note that the 3,5 mm jack plug and the earphone socket are stereo versions. One channel is used for audio and one for cloning data transfer.

The ICOM OPC-478U is a special USB serial interface cable kit that transfers data from your Icom IC-R5, A24 and A6 to your computer via your PC's USB Socket. The kit includes the OPC-478U interface box, the OPC-1045 USB cable and a driver diskette. The OPC-478U can also be connected to a USB 2.0 port, however it will be transferring data in the USB 1.1 format. It is recommended that the OPC-478U not be used with a USB extension cable as data errors may result.

• When using the OPC-478U for the first time, while Windows is running, the "New Hardware is found" dialog box appears. In this case, the USB driver installation is necessary. Icom provides these drivers on a 3.5 inch diskette that is included with your OPC-478U. It features drivers for: Windows XP, Windows 2000 and Windows 98/ME environments.
