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-1221D/1222D feature two Ethernet ports with one
IP address for easier network wiring. One port can be used to connect to the
network, and the other port can be used to connect to another Ethernet device or
another EKI-1221D/1222D. 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-1221D/1222D 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.
