-====== NB3710 Extension Ports ======
-The NB3710 has an M12 extension connector with 8 pins. The 8 pins are split into two logical ports: Pins 1 to 4 represent Extension Port 1 (EP1) and pin 5 to 8 represent Extension Port 2 (EP2). In common, EP1 host the serial line of the router, which is a 3-wire RS-232.
-Some NB3700 variants use the Digital I/O connector as extension connector. The same pin assignment applies for these variants.
