CSC-187 Industrial Ethernet Switch is the industrial real-time Ethernet switch and its anti-jamming capacity conforms to the highest EMC/EMI standards of IEC, which enable it to be suitable for the application requirements of various harsh industrial conditions. Viewing from the temperature design, CSC-187 adopts advanced heat dissipation technology and low power consumption technology to ensure that the device can normally operate at wide temperatures (-40~+85°C) with the optical fiber connection opening configuration. CSC-187 possesses 28 totally configurable ports, where 4 of them can be configured to be Gbit port. It is integrated with SNMP network management protocol, Modbus and other industrial protocols. CSC-187 supports 1588 STP, RSTP, MSTP and other international standard ring protocols as well as private RING protocols. It has private RING protocols that have independent intellectual property, which not only reduce “ring opening” recovery time and improve real-time performance, but also support such topology structures as Star Topology, Ring Network Topology and Tree Topology etc.
