The Jumper W1 on the PXI-6508 is used to select pullup to 5V or pulldown to GND. However the HI and LO positions for the Jumper W1 are not labeled on the PXI-6508 card, nor is there any picture or drawing or diagram in the manual (320938c: "PCI-DIO-96/PXI™-6508/PCI-6503 User Manual"). Can somebody point me to some type of documentaion that indicates which position is the HI position and which position is the LO position? Thanks, Kevin.
