System CMOS
The NI PXI-8184/8185 contains a backed-up memory used to store
BIOS configuration information.
Complete the following steps to clear the CMOS contents.
1. Power off the chassis.
2. Remove the controller from the chassis.
3. Move the jumper on J1 from pins 1-2 to pins 2-3, as shown in
Figure 2-3.
4. Wait one second. Move the jumper back to pins 1-2.
5. Reinstall the controller in the chassis.
Caution Do not leave the jumper on pins 2-3. Doing so decreases battery life.
