EKI-1221/CI/I EKI-1222/CI/I EKI-1224/CI/I 1-port Modbus Gateway 2-port Modbus Gateway 4-port Modbus Gateway Features Provides 2 x 10/100 Mbps Ethernet ports for LAN redundancy Integration of Modbus TCP and Modbus RTU/ASCII networks Supports up to 921.6 kbps, and any baud rate setting Supports up to 16 connections and 32 requests simultaneously Auto searching slave ID over configuration utility Software selectable RS-232/422/485 communication Mounts on DIN-rail and Wall mount Built-in 15 KV ESD protection for all serial signals Automatic RS-485 data flow control Supports surge protection for D.C. power ports with line to line 2 KV, and line to earth 4 KV; for signal ports with 4 KV. 'I' models support a wide operating temperature EKI-1221 EKI-1222 EKI-1224 'CI' models support isolation and wide operating temperature Introduction The EKI-1200 series Modbus gateways are bi-directional gateways for integrating new and existing Modbus/RTU and Modbus/ASCII serial devices to newer TCP/IP networked-based devices. The EKI-1221/1222/1224 feature two independent Ethernet ports and MAC addresses to provide a redundant networking mechanism to guarantee Ethernet networking reliability. They provide a simple and cost-effective way to bring the advantage of remote management and data accessibility to thousand of devices that can not connect to a network. The EKI-1221/1222/1224 provide a feature that can allow users to select master or slave operation mode for each serial port. They not only allow an Ethernet master to control serial slaves, but also allow serial masters to control Ethernet slaves.
