DESCRIPTION
The GS-P8-A and GS-P8-E are Bidirectional Data
Line Protection systems against EOS (Electrical
Over Stress) and ESD (Electrical Static Discharge).
These subminiature male/female connector, de-
signed both for EIA RS232C and V24 with 8 lines,
shunts to ground hazardous overvoltages induced
on an EIA cable.
