I have a Panasonic Toughbook CF-53SALP8LM and it has this odd connector on the back that I cannot figure out.Normally I can find what I need on google, but I have no idea where to start with this there's nothing in the device manager or the Panasonic manual that came with it that gives any hint to what this connector is.
Garry is right. You probably will never use those.
According to the manufacturer's datasheet, these are dual pass antenna connectors, for adding external wi-fi aerials, for example if being mounted in a vehicle to a roof mounted aerial.
