In addition there is an optional interface slot that allows you to install different communications cards. It can be used parallel with either the RS232 or USB ports.
Currently there are two cards available for the optional interface slot. An SNMP/WEB card allows management and monitoring over a network or internet, and the AS/400 card allows voltage free relay contacts. Your local dealer will have more information about these option cards.
