RS-232 Port Protection
Problem: Short-circuit overload
RS-232 cable can be mis-connected or a foreign metal object placed into the connector can cause an overcurrent event, which could damage internal electronics.
|
| |
|
Solution: PolySwitch devices.
PolySwitch devices help limit the flow of dangerously high currents during fault conditions and reset back to normal operating mode once the fault condition is removed.

Problem: Transient Surge Voltages and Electrostatic Discharge (ESD)
Transient surge voltages caused by lightning strikes and equipment switching operations and also electrostatic discharge (ESD) can damage the equipment.
|
| |
|
Solution: Gas Discharge Tubes (GDTs).
Gas Discharge Tubes (GDTs) help protect the sensitive data transmission lines equipment by switching to a low impedance state, and diverting energy away from the equipment. Due to their low capacitance, the GDTs introduce much less signal distortion than other overvoltage protection technologies.
