BAROMETRIC REFERENCE (BARO) MODULE INSTRUCTIONS
Installation of the BARO module in the power bay allows you to convert your gauge pressure measurement to the absolute scale if so
desired. You may also view the barometric reference reading directly on a dedicated numerical screen. When the BARO module is installed, it may also be
disabled in CrystalControl to conserve battery power, however your nVision will not be able to display absolute readings unless it is active.
Installation
The BARO module is located in the power bay of the nVision. As with the traditional modules, installation of the BARO module should be done in a ESD
compliant, dry, clean environment, using the instructions below.
!
CAUTION:
The BARO module requires CPLD version 6 or greater to operate properly. If you have CPLD 5 or earlier the nVision must return to the
factory for updating. You may determine your CPLD version in the Chassis Summary screen or in CrystalControl.
1
Place the nVision face down on clean stable work surface.
2
Remove USB power connection and power pack from the nVision.
3
Remove your BARO module from factory packaging, grasp the cover, and orient as shown.
4
Slide the BARO module into the connector system.
5
Insert screw through cover and into the nVision, and tighten to 16 in-oz (0.11 newton meter (N-m)) torque to secure BARO module properly.
Note:
Remember to enable the module in CrystalControl if module is a new installation.
Note:
Reset the nVision chassis after enabling or disabling the BARO.
