on the WJ200. Do you know were I can find a pin out of the cable or instructions on what
I need to make?
You need an RS232 to RS485 converter if using com port. You can also USB to RS485 converter. A cheap converter from ebay didn't work for me with WJ200 I had to go with a B&B converter http://www.bb-elec.com/product11.asp?sku=485ldrc9
