Advantech EKI-1224 / CI / I

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-1224 feature two independent Ethernet ports and MAC addresses to provide a redundant networking mechanism.
