2.3 Physical Interface
All 411x units provide a RS232/RS422/RS485 interface port and a 10/100 Base-T Ethernet port. Both ports are
available when the unit is installed and powered up. Commands may be sent to either port at any time and they
will be processed in the order that they are received. The RS232/RS422/RS485 signals connect via an 18-pin,
MS3112E14-18S connector. The Ethernet signals connect via a standard RJ45 connector, Part #RJF6G.
