2. Grounding Variations

There are several possibilities for individual grounding. The following items correspond to the
drawing.

1. Standard grounding is to connect the ground terminals (marked with an "S") with the shield
of the incoming cable, individual grounds are not connected.

2. Connecting the pads beside the numbers 1 - 24 with some solder leads to a connection
between that channel and the common ground.

3. Connect the common ground with the chasis ground by setting the jumper to position
"CHASSIS-COMMON".

4. To group ground, you have to remove the small tracks between the groups of channels.
