Black Box RS-232 Surge Protector surge suppressor

Zap! and your data's gone. You've spent hours creating the data stored on your network, but in a split second you could lose it all. Don't let your worst nightmare come true - protect your sensitive data from surges and spikes. Power surges can enter through your AC circuits, but they can also enter through your data lines. You might already have AC surge protectors, but you still need data line protectors. The complete line of data protectors provides protection for virtually any type of interface. Choose from protectors for twinax or coax cable, RS-232 and RS-422 lines, telco, T1, CSU/DSU, or Ethernet, ARCNET, and Token Ring interfaces. All the protectors guard your data against ground-loop currents, electrostatic discharge, surges, and spikes.
