For more information, refer to the Analog Input and Timing Circuits section in Chapter 3, Theory
of Operation.
To install either the capacitors or the resistors, perform the following steps before installing your
module in the SCXI chassis:
1.
Take off the module cover by removing the grounding screw at the rear of the module.
2.
Take off the rear panel by removing the two other screws.
3.
Slide the module out of its enclosure.
4.
Insert the capacitor(s) and/or resistor(s) into their appropriate pads.
5.
Solder the leads to the pads on the solder side of the board.
6.
Trim the leads to 0.06 in. maximum.
7.
Slide the module back into its enclosure.
8.
Reinstall the rear panel.
9.
Reinstall the top cover and grounding screw.
Your module is ready to be installed into the chassis.
Hardware Installation
You can install the SCXI-1100 in any available SCXI chassis. After you have made any
necessary changes and have verified and recorded the jumper settings (a form is included in
Appendix G, Customer Communication), you are ready to install the SCXI-1100. The following
are general installation instructions. Consult your SCXI chassis user manual for specific
instructions and warnings.
1. Turn off the computer that contains the data acquisition board or disconnect the data
acquisition board from your SCXI chassis.
2. Turn off the SCXI chassis. Do not insert the SCXI-1100 into a chassis that is turned on.
