1-Port Modbus Gateway 2-Port Modbus Gateway 4-Port Modbus Gateway Features 2 x 10/100 Mbps Ethernet ports for LAN redundancy Integrates Modbus TCP and Modbus RTU/ASCII networks Supports up to 921.6 kbps and any baud rate setting Supports up to 16 connections per serial port under Modbus master mode and 32 sessions under Modbus slave mode Software-selectable RS-232/422/485-2w/485-4w communication Mountable via 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 DC power ports with line-to-line (1 kV) and line-to-earth (2 kV) for signal ports with 2 kV "I" models support a wide operating temperature EKI-1221 "CI" models support isolation and a 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 redundancy and reliability. They provide a simple and cost-effective way to bring remote management and data accessibility to thousands of devices that cannot otherwise connect to a network. The EKI-1221/1222/1224 allow users to select master or slave operation mode for each serial port. In addition to allowing an Ethernet master to control serial slaves, they also allow serial masters to control Ethernet slaves.
