Perle Systems Technical Notes
Anytime a product connects to the outside world, electrostatic discharge is a threat that can cause serious damage to electronic components.
RS232 cabling is highly susceptible to these harmful discharges.
According to the Electrostatic Discharge Association http://www.esda.org, “Industry experts have estimated average product losses due to static to range from 8-33%. Others estimate the actual cost of ESD damage to the electronics industry as running into the billions of dollars annually”
Don’t risk your operation with serial cards that do not have this protection.
All Perle serial cards include ESD protection circuitry and are tested to withstand ESD events up to ±15kV based on the Human Body Model, EN61000 4-1 ( IEC1000-4-2 ) Air-Gap Discharge standards providing the reliability needed for continuous operation.
