Pin Contacts
Often the pin contacts used in cabling are not given enough attention. The ideal choice
for a pin contact uses a design similar to Molex’s or Trifurcon’s design that provides
three distinct points to maximize the contact area and improve connection integrity in
high shock and vibration applications.
Power Down
Make sure that power has been removed from the system before making or breaking
any connections.
I/O Connections OFF
—I/O Connections should also be off before connecting them to
the embedded computer modules or any I/O cards. Connecting hot signals can cause
damage whether the embedded system is powered or not.
