Advantech EKI-1211
1-Port RS-232/422/485 Modbus Gateway





- 1 x 10/100 Mbps Ethernet port
- Integrates Modbus TCP and Modbus RTU/ASCII networks
- Baud rate: supports up to 230.4 Kbps
- Supports up to 16 connections per serial port under Modbus client mode and 32 sessions under Modbus server mode
- Built-in 8-kV ESD protection for all serial signals
- Software-selectable RS-232/422/485-2w/485-4w communication
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-1211 feature one independent Ethernet ports and MAC address. It provides 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-1200 series allow users to select client or server operation mode for each serial port. In addition to allowing an Ethernet client to control serial servers, they also allow serial client to control Ethernet servers.
