1.1.3 Frequently Asked Questions
Can I Operate PowerVista/312 with the Unit Closed ?
Yes. As long as your unit is configured for your acquisition, has the signal connections correctly made, and has
been properly powered-up, you can close the unit, lock it, and allow the acquisition to take place automatically.
Note: It is important to keep PowerVista/312’s openings free of obstruction to ensure adequate airflow. Also
see the following question, How Do I Keep the System Cool?
How Do I Keep the System Cool ?
The unit is self-cooled by its own fan, providing the flow-holes for air circulation are not obstructed. The fan
draws air into the right-side of the lower casing. Air flows beneath the cover plate, then up through holes in the
right-side of the plate. When the case cover is closed, air then flows across the laptop and back out through the
flow-holes in right side of the upper casing.
Note: It is important that you keep PowerVista/312’s openings free of obstruction to ensure adequate airflow.
Also keep the fan intake away from dirt and dust to avoid the intake of foreign material.
What Does the UPS Option Do?
The UPS (uninterruptable power supply) is a system option. The UPS is a power distributor and a rechargeable
power source. When fully charged, the UPS option ensures the PowerVista/312 acquisition device will receive
power for up to three hours when there is no AC available, or when there are periods of bad AC. In the first
case the UPS device is functioning simply as a battery.
Note: PowerVista/312’s UPS option is intended only for use with the acquisition device. It is not intended
for use with the laptop and the system receptacles do not have UPS protection.
Where Should I Plug In the Laptop’s Adapter ?
PowerVista/312 contains two 110 VAC outlets that are intended for use by your laptop’s power adapter. If the
power adapter is mounted on the cover plate, you can use the cover plate’s outlet. If you mount the adapter
beneath the cover plate, you can use the internal outlet that is clearly visible near the right side of the device,
once the cover plate is removed.
Note that the system’s 110 VAC power outlets will have power available as long as the PowerVista/312 is
plugged into a live power source. The cover plate switch and LED do not pertain to PowerVista/312’s AC
outlets.
