EKI-1221 EKI-1222 1-port Modbus Gateway 2-port Modbus Gateway Features NEW Provides 2 x 10/100 Mbps Ethernet ports for LAN redundancy Integration of Modbus TCP and Modbus RTU/ASCII networks Supports baud rates up to 921.6 kbps Supports up to 16 connections and 32 requests simultaneously Supports 31 slaves per serial port Easy-managing Advantech Serial Device Server Configuration Utility for Windows 2000/XP/Vista (x86) Auto searching slave ID over configuration utility Software selectable RS-232/422/485 communication Mounts on DIN-rail, wall or panel Built-in 15 KV ESD protection for all serial signals Automatic RS-485 data flow control EKI-1221 EKI-1222 RoHS COMPLIANT 2002/95/EC 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 and EKI-1222 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 and EKI-1222 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.
