I'm planning to use an XD1230 for emergency/disaster status information and during certain scenarios Internet access might not be available. I see a lot of posts regarding the use of a GPS connected to USB port 2 for determining location and geofencing. I also see a lot of posts regarding setting the internal clock using NTP with an Internet connection. I haven't found any mention of using the GPS NEMA 0183 data stream to set the internal clock to display accurate time. A received GPS time signal is as good as NTP and maybe better for any scenario I can envision involving Brightsign, if the GPS can be properly positioned to receive signals..
Since there is a designated GPS USB port, is there a provision in the firmware for setting the internal clock from a NEMA 0183 data stream?
