Option I - Isolated Serial Communications
Features:
The isolated serial option board (I) provides an RS232C, RS485 or an RS422 serial interface. The port is software configurable for any of these modes.
RS485 requires a 120-Ohm terminating resistor at each end of the transmission line and RS422 requires a 100-Ohm terminating resistor at the receiver end of the transmission line only.
