Hi I try to connect my Delta by the serial nmea output to com port 1. I connected the white cable Out TX+ to pin 2 and Blue Out Tx- to pin 5. But i don't get any nmea input on com port 1. When i use my older GPS with the same cable it works fine. Is there anything to configure on the Delta beside the NMEA Protocol? It should send the signal even if it does not have a gps connection nether it has to be connected to a 12v source?

Best Regards Roger
