Dual port connector
The serial port is a dual-port RJ45 connector. The two ports have identical pinouts and
are interchangeable. Two ports are provided to support daisy chain connection of a CAN
bus or RS485. It can be also used to connect two types of communication channels at the
same time, instead of splitting a cable from a single RJ45 connector.
