RSL AND GND CONNECTORS ON IDU
The RSL (Received Signal Level) and GND (Ground) front panel test points are both single connection female
test points that permit insertion of a 0.062” test probe pin from a VOM (Volt Ohm Meter). The test point is
located on the IDU just below the “Proxim” logo and the radio type on the unit.
