Configuring Pin H to be Shield or Ground

Determine if the channel is already configured as a ground or a driven shield. Using

a multimeter, set the meter to check for resistance. Measure between pin H and the front

panel ground connector. If the resistance is under 10 ohms, that channel's pin H is set to

ground.

To convert the channel so that the braid is a ground, rather than a shield, remove

the cover, and look for two large capacitors on rear of the channel board. Near the

capacitors is a black jumper (J100). The jumper spans 2 of 3 pins on the connector on the

board. If the jumper is near the side marked GND, it is set to ground. If it is over to the

other side, it is a shield.
