Tripp Lite DRS232 Network Dataline Surge Protector/Suppressor RJ45 100 BaseT-4 RS-232

Tripp Lite\'s DRS232 offers data-line surge suppression for the protection of POS equipment, serial printer spoolers, multiplexers and other network devices using RS232 ports running on unshielded twisted pair (UTP). Convenient RJ45 input and output connections with included 5 inch Ethernet patch cable allows convenient in-line placement at the protected device network connection. Surge suppression is handled with balanced arrays of high-speed avalanche diodes that divert excess energies created by electrostatic discharges, faulty wiring or lightning away from network interface connections. Tripp Lite network surge suppressors reduce blown interface cards, garbled transmissions, system lock-ups and hard equipment failure by safely shunting data-line surges to ground. Six-inch heavy guage grounding lead connects to designated grounding lugs available on the back panel of most network workstations and pieces of internetworking equipment. Suppression: 1 set RJ45 in/out jacks, protects wires 1-8, 18V clamping. (Amazon)
