Port 2 is working in RS-422 mode. BIASing resistor and Tx , Rx termination resistors are enabled.
Port 3: RS485 auto, 2-wire with Echo (none)
Port 3 is working in RS-485 half duplex mode with automatic data receive and transmit control. BIASing resistors and
termination resistors are disabled.
Port 4: RS485 by RTS, 2-wire no Echo (BIAS, TxTerm)
Port 4 is working in RS-485 half duplex mode. BIASing resistors and Tx termination resistors are enabled. The data
receive and transmit control is by RTS signal.
