The outer conductor of the coax cables are isolated from system
earth ground.
When using the 75-ohm interface, jumper straps JP2, JP5, JP6, and JP7
must be installed over the jumpers. The jumpers are located next to the
BNC connectors. Do the following to configure the jumpers:
1. Open the case by inserting a screwdriver into the slots and twist the
screwdriver head slightly. The top half of the case will separate from
the lower half of the case. Take caution not to damage any of the PC
board mounted components
2. Open the case and install jumper straps for JP2, JP5, JP6, and JP7.
