Grounding jumper X1
The Grounding jumper X1 on the OPTC8 is used for grounding selection. If position ON is selected it
means that the D-sub connector PIN1 is connected directly to ground. Selection of position OFF
means that PIN1 is connected to ground via an RC-filter. Jumper X1 has no effect on OPTC2.
