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