The EKI-1221/1222/1224 feature two independent Ethernet ports and MAC addresses to provide a redundant networking mechanism to guarantee Ethernet networking reliability. 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-1221/1222/1224 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. 1-port Modbus Gateway 2-port Modbus Gateway 4-port Modbus Gateway EKI-1221 EKI-1222 EKI-1224 Power & Energy Automation 8 5 4 4 10 Panel PCs 9 iDoor Technology Modules 8 Industrial monitors 7 Industrial IoT Gateways 6 Control Cabinet PCs High-Performance Control Panels Industrial Operator Panels 3 2 IntelligentMotionControl andMachineVision 1 11 Control IPCs 12 Remote DA&C Systems 13 Wireless IoT Sensing Devices 14 15 RS-485 I/O Modules 16 Thin-Client Terminals Industrial Ethernet Solutions 17 IP Gateway and Serial Device Servers iNetworking 18 19 WebAccess+ Solution Ethernet I/O Modules Chapter 18 Table of Contents Table of Contents
