4.1.4 Cellular Center Pin Short To Ground or Open Protection
The Asset-Link cellular Center Pin has protection for application of a connection to
“Ground” or a “Open”without damage to the cellular transmitter electronics. For this
test, the shell of the connector is ground.
4.1.5 Cellular Center Pin Over Current Protection
The Asset-Link cellular Center Pin has a high impedance to ground. This pin should
not conduct current for application of normal vehicular voltages.
4.1.6 Cellular Center Pin ESD Protection
The Center Pin will withstand an Electrostatic Discharge (ESD) of ±15Kv. The
discharge network of 150pf/150ohm with a low impedance ground return follows the
standard IEC 1000-4-2. This ESD is of greater energy than the requirement of
Electrostatic Discharge per SAE J1211 section 4.11, and ensures operation after ESD
testing. The Asset-Link ESD test pass/fail is a functional test at the completion of the
discharges.
