Two Modbus Gateways with built-in Ethernet switches, the EKI-1221D and EKI-1222D provide transparent connection between Modbus (ASCII, RTU) serial devices and Ethernet based Modbus/TCP equipment. They have built-in Ethernet switches for cascading/daisy-chain connectivity. Cascading connections support Ethernet auto-bypass to prevent accidental power failure in the event one of the Modbus Gateway’s unexpectedly shuts down. They come with Windows utilities and web-based configuration for easy set up. One port can be used to connect to the network, while the other can be used to connect to an Ethernet device or another EKI-1221D/1222D. They provide 921 kbaud speeds and they support 16 TCP masters, 16 TCP slaves, and each serial port supports up to 31 RTU/ASCII slave devices.
