Long Range Ethernet Extenders
CopperLink CL2320R Long Range Ethernet and RS-232 Extender | up to 4 miles (6.5 km) over copper

This Ruggedized Extender offers Ethernet and Async. RS-232 extension over a single copper pair. Supporting point-to-point, multi-point, daisy-chain, or ring topologies, delivers low-latency links for industrial control, metering and signaling applications.

• Ethernet and Serial - Ethernet and RS232 Extension and Distribution. Two 10/100 Ethernet Ports and One RS232 Async Port.
• High Speed Transport - Achieves 15Mbps over 1 twisted pair. Symmetrical rates are automatically adapted to the copper line conditions (noise environment, wire gauge/type and length).
• All Topologies - Supports point-to-point, multi-point, daisy-chain, and ring topologies.
• Long Range - Supports distances of 4 miles (6.5 km) for each span. The number of remote sites and total distance is almost unlimited based on the bridging and repeating capabilities.
• Serial Device Server - It has an asynchronous serial to IP converter function (encapsulation) over UDP and TCP plus Telnet, Raw-IP, Message/Bloc, HNZ and MODBUS adaptation suitable for industrial data acquisition and control. Serial Master/Slave multipoint modem emulation.
• QoS Traffic Prioritization - Rate Limiting and Priority Queuing functions enable prioritization of traffic types, such as time sensitive signaling or video streams. IP/DSCP, VLAN 802.1Q, Priority Queuing.
• Packet Forwarding - A store and forward engine performs optimal packet forwarding, delivering the lowest latency for end-to-end transfer.
• Highly Secure - Network access is secured by various standards for authentication and access control. STP, RSTP Secured Ring, 802.1X, and Radius.
• Management - via local USB port (Host/Device), via SSH, HTTP, HTTPS, SNMP, FTP and intuitive Web User Interface.
• Ruggedized - Built into sturdy metal enclosure offering operating temperatures from -20 to +70�C, without fans, so it works in industrial environments with hot, cold, or humid conditions.
• Flexible Mounting - It comes with DIN rail mounting kit for panel builds and can also be installed in a 19� rack.

The CL2320 Series Ethernet Extenders deliver point-to-point, multi-drop (bus) or ring topologies.  With Northbound and Southbound composite (extension) interfaces, the device allows Ethernet and RS-232 to be dropped at remote locations at distance over copper twisted pair.   A built-in Device Server delivers serial RS-232 extension and/or connectivity to IP.
