Having got the Audio interfacing to the V5 sorted it was time to look at the serial data. The V5 has no RS232 connectors and only 2 USB ports. Normally I have one serial connection to the radio (9 pin), one to the GPS (9 pin for timing) but now I needed an extra one for the winkey usb (true USB), having recently discovered my WinkeyUSB in a drawer along with the V3 chip which I installed. I could have used a USB hub but past experience has found them unreliable in RF environments. Searching my goodies box I found my Edgeport /4 USB serial converter (bought off Ebayusa for $10) that I used to use on my old Win XP contest computer. This box has one USB connector and four 9 pin serial sockets. I could connect the Radio and the GPS to the Edgeport box and the Winkey USB directly to the computer, leaving 2 spare com ports.
Configuration software and drivers were available for Windows 7. Comports can be allocated as desired, I used COM3, COM4, COM5 and COM6. WINKEY USB has COM2
