EKI-1121L 1-port risc-based communication controller ? eki-1122l 2-port risc-based communication controller introduction EKI-1121L and eki-1122l are risc-based embedded communication controllers which provide dual auto-sensing 10/100 mbps ethernet ports for network redundancy and one or two software-selectable rs-232/422/485 serial ports. the EKI-1121L and eki-1122l use the arm7 risc cpu which is a powerful computing engine to fulfll data compression or protocol conversion requirements. the built-in 8 mb fash rom and 16 mb sdram provide user enough storage to run their specifc applications. 1-port risc-based industrial communication controller 2-port risc-based industrial communication controller EKI-1121L eki-1122l rohs compliant 2002/95/ec new
