RS485 serial
port expansion
● Output voltage: 13–15 V DC (rated voltage: 14.5 V DC)
● Four RS485 ports with the default communications rate of
9600 bit/s.
● COM1–COM3 ports provide 12 V DC power.
● The power supply can be switched on or o and is on by
default.
POE expansion Supports two POE (GE) ports for expansion of the POE bus,
and supports network isolation and ring network.
