| VIA EPIA COM2 Not Working |

I was setting up the OBD2 reader on my Carputer and when I attached the serial header to the motherboard to make COM2 (Second Serial Port) that is internal active, I could not send any data or receive data... I had everything enabled, and there are many posts on the VIA forums about this problem. Well it's not really a problem, more like a different specification of pin ordering. Depending on where you got your serial header, it may, or may not work correctly with the serial header on the VPA EPIA motherboards. All you have to do it rewire the pins going to your header device, or to the serial device you are trying to use. I rigged together a small box that moves around the ports off my 'incorrect' serial header into a correct serial port for the device I was using. If you look into the PDF manual for the motherboard, it will give you a chart with the exact pinout of the serial header. Use this, along with the pinout on a 9 pin D sub serial port to find the correct pins that you need to move. Set as Favorite Bookmark Create PDF
