Please Help With Verifone Ruby 2 POS Integration

So, the usb into the server and then just find the right com port for the specific usb to send the data into VMS?

My customer's district managers know how to program the com ports on the back of the Ruby Terminal to a Virtual Journal. But I also work with the local POS Register Service Provider. Each Ruby Register will need this done. Then at the DVR/NVR you will need a USB to Serial Adapeter. We have been using the Trendnet. Plug 1 in at a time and see which com port Windows assigns to it by looking at the Device Manager. Verifone has a RJ45 to 9 pin NUll Modem Adapter that is RED that works or make your own. We have customer using Digiop this way. The only time that this will NOT work is if the printer at each register virtually prints a journal. The old old printers acutally had a second roll paper that printed the journal. if this is the case yoiu have T Tap by a 3 female RJ45 Adapter and still use the RJ45 to 9pin Null Modem at the DVR side. It's said that DIGIOP couldn't help you out on this.....Remember you can use hyperterminal or putty to see the raw data with your laptop and USB to serial adapter to see if you transmitting data. Have you done POS integration before?

This is the first pos for me. That's why my questions seem so elementary. I really appreciate the help.
