I found that I have a VMSpc model JR500 J1708 Interface Board, v.2.01 software v1.10 in my motorhome. I would like to use this with my HP dv6-1245dx laptop, running Windows 8.1 Pro 64 bit, which has no serial ports. Will this VMSpc unit work with my laptop with the proper Serial-to-USB adapter? If so, then is there a recommended adapter that works well with Windows 8.1 Pro, 64 bit? I am anxious to use VMSpc, and would like to us this unit, if it will work well, instead of purchasing an entirely new cable assembly. Thanks!
