the format: for input channel x, the resistor is RCLx. For example, the
resistor for channel 28 is RCL28.
Caution:
Before installing the resistors in your module, make sure that there are no
signals connected to your module front connector.
Before installing your module in the SCXI chassis, you must install the
resistors by performing the following steps:
1.
Ground yourself via a grounding strap or via a ground connected to
your SCXI chassis. Properly grounding yourself prevents damage
to your SCXI module from electrostatic discharge.
2.
Remove the grounding screw of the top cover.
3.
Snap out the top cover of the shield by placing a screwdriver in the
groove at the bottom of the module and pushing down.
4.
Remove the rear panel by unscrewing the two remaining screws.
5.
Slide the module out of its enclosure.
6.
Bend and trim the resistor lead as shown in Figure 2-3. Be sure that
the resistor does not extend more than 0.65 in. above the surface of
the circuit board.

7.
Insert the resistor into the appropriate pad, labeled RCLx.
8.
Solder the leads to the pad on the bottom side of the module.
9.
Slide the module back into its enclosure.
10. Reinstall the rear panel.
11. Reinstall the top cover and grounding screw.
