Overview

EKI-1122LThe EKI-1122L is a RISC-based embedded communication controller which provides dual auto-sensing 10/100 Mbps Ethernet ports for network redundancy and two software-selectable RS-232/422/485 serial ports. The EKI-1122L uses the ARM7 RISC CPU which is a powerful computing engine to fulfill data compression or protocol conversion requirements. The built-in 8 MB flash ROM and 16 MB SDRAM provide user enough storage to run their specific applications.
