The I-7188XG is an embedded controller and powered by an 80188-40 processor with 512K bytes of static RAM, and 512K bytes of Flash memory. It provides one serial RS-232/RS-485 port(Jumper Selectable) and one RS-485 port. The I-7188XG also supports an optional battery back-up SRAM expansion board and Flash-Rom board, providing non-volatile mass storage from 2 megabytes to 64 megabytes.
