Caution Do not hot-swap USB devices while the cRIO-9081 is in a hazardous location or connected to high voltages. If the cRIO-9081 is not in a hazardous location, you can connect and disconnect USB devices without affecting operation. Video Port (VGA) The cRIO-9081 VGA port outputs graphics using VESA standard VGA analog signaling.
RJ-45 Gigabit Ethernet Ports The cRIO-9081 has two tri-speed RJ-45 Gigabit Ethernet ports. By default, both Ethernet ports are enabled and configured to obtain an IP address automatically. The Ethernet ports can be configured in MAX. The following table shows the pinout for the RJ-45 Gigabit Ethernet ports.
If you apply power to both the V1 and V2 inputs, the cRIO-9081 operates from the V1 input. If the input voltage to V1 is insufficient, the cRIO-9081 operates from the V2 input.
The FPGA continues to run unless you select the Autoload on Any Device Reset boot option. CMOS Reset Button The cRIO-9081 has a CMOS reset button that you can use to reset the CMOS and the BIOS. LEDs The cRIO-9081 provides the following LEDs.
The DRIVE LED is lit yellow when an internal drive is being accessed. STATUS LED Indicators The STATUS LED is off during normal operation. The cRIO-9081 indicates specific software error conditions by flashing the STATUS LED yellow a certain number of times every few seconds, as shown in the following table.

If the problem persists, contact National Instruments. The cRIO-9081 indicates specific hardware error conditions by flashing the STATUS LED red a certain number of times every few seconds, as shown in the following table. Table 13. STATUS LED Hardware Indicators...
The cRIO-9081 provides a chassis grounding screw. NI cRIO-9081 1. Chassis Grounding Screw For EMC compliance, you must connect the cRIO-9081 to earth ground through the chassis ground screw. Use wire that is 1.31 mm (16 AWG) solid copper wire with a maximum length of 1.5 m (5 ft).
CMOS BATTERY IS DEAD battery is dead. The cRIO-9081 still starts, but the system clock is reset to the date and time of the BIOS release. The battery is not user-replaceable. If you need to replace the CMOS battery, contact NI.

You can also mount the cRIO-9081 in other orientations, on a nonmetallic surface, on a 35-mm DIN rail, on a desktop, or in a rack. Mounting the cRIO-9081 in these or other configurations can reduce the maximum allowable ambient temperature and can affect the typical accuracy of modules in the cRIO-9081.
Mounting Requirements Your installation must meet the following requirements for cooling and cabling clearance. Allow 50.8 mm (2.00 in.) on the top and the bottom of the cRIO-9081 for air circulation, as shown in the following figure. Figure 6. cRIO-9081 Cooling Dimensions...
Ambient Temperature Measure the ambient temperature at each side of the cRIO-9081, 63.5 mm (2.50 in.) from the side and 50.8 mm (2.00 in.) forward from the rear of the cRIO-9081, as shown in the following figure. Figure 8. cRIO-9081 Ambient Temperature Location 50.8 mm...
Fasten the cRIO-9081 to the surface using the M4 screws appropriate for the surface. Screws must not exceed 8 mm of insertion into the cRIO-9081. Tighten the screws to a maximum torque of 1.3 N · m (11.5 lb · in.).
Mounting the Device on a Panel You can use the NI panel mounting kit to mount the cRIO-9081 on a panel. What to Use • cRIO-9081 • Screwdriver, Phillips #2 • NI panel mounting kit, 781919-01 – Panel mounting plate –...

BIOS Configuration Resetting the System CMOS and BIOS Settings The cRIO-9081 BIOS configuration information is stored in a nonvolatile memory location that does not require a battery to preserve the settings. Additionally, the BIOS optimizes boot time by saving specific system information to memory backed up by a battery (CMOS).

Reset the DIP switches to their normal positions. Power-On Self Test Warning Messages The cRIO-9081 POST displays warning messages for specific issues onscreen. You can use MAX to enable Console Out to send these warning messages through the RS-232 serial port.
This warning indicates that the BIOS settings have the default values. • Warning: Recovering from CPU Overtemp—This warning indicates that the thermal protection features of the cRIO-9081 shut down the system because of a high CPU temperature. • Warning: Recovering from Ambient Overtemp—This warning indicates that the thermal protection features of the cRIO-9081 shut down the system because of a high ambient temperature.
The Advanced setup menu contains BIOS settings that do not require modification for normal operation of the cRIO-9081. If you have specific problems, such as unbootable disks or resource conflicts, you may need to examine the settings in this menu.
Hardware Prefetcher—This setting enables or disables CPU cache hardware prefetching. The default value is Enabled. • Adjacent Cache Line Prefetch—This setting enables or disables prefetching of adjacent cache lines from memory to the CPU cache. The default value is Enabled. 32 | ni.com | NI cRIO-9081 User Manual...
DC power is lost. Valid values are Stay Off and Turn On. The default value is Turn On. When set to Stay Off, the cRIO-9081 returns to the soft off power state after AC power is restored. When set to Turn On, the cRIO-9081 powers on when DC power is restored.
