User-configurable jumpers

- Jumpers W1 through W8 ground the negative inputs of each input through 100 kΩ resistors for floating sources and transducers. 

- Jumper W9 allows the module to connect to a single-ended data acquisition board instead of a full differential board. 

- Jumper W12 determines the connections between the SCXIbus guard, chassis ground,  and the data acquisition board analog ground. 

- Jumper W14 carries the SCXIbus MISO line, after buffering, to the SERDATOUT signal on the rear signal connector. 

- On Revision C and later modules, jumper W13 connects a pullup resistor to the  SERDATOUT signal on the rear signal connector.
