EKI-1121L 1-port RISC-based Industrial Communication Controller
Overview
The EKI-1121L is a RISC-based embedded communication controller which provides dual auto-sensing 10/100 Mbps Ethernet ports for network redundancy and one software-selectable RS-232/422/485 serial ports. The EKI-1121L 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.
