Advantech EKI-1222 / 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-1222 provides a feature that can allow users to select client or servers operation mode for each serial port.
