Nmea2000 software cable to upgrade

[winb377]

I hope someone can point me in the right direction. I need to install 2.5 software onto our NEW SMIS Gauges that came with the 2.6 software which is giving me codes flashing up on the gauges "keyless error" etc... I have downloaded the Emulator software etc and now just require the cable that connects from the laptop to the system. Does anyone have a link or a place I can buy this from and is there anything else I need. Thanks dealer has quoted silly money to do this. Thanks very much

Google usb to nmea 2000, you will get many options. None of them cheap!
