We’re having issues getting GPS data from a freshly installed MAX-HD4-LTEA-WF-T that replaced an HD2. According to the installer, the GPS antenna is hooked up, re-using the old antenna, however the installer noted that there were 2 GPS ports on the back of the unit and 2 GPS antennas were in the box. I’m unable to find any documentation showing 2 GPS ports. Is one of the GPS ports ‘special’ in someway, or can we activate/use both at the same time? Are the antennas compatible between models, or does the new HD4 require the antennas that it came with?
We’re trying to get someone local to move the GPS antenna to the other port, but that may not happen for a few days.
