Installation and Configuration
Inhibit Mode Switch
On the rear panel of the chassis there is an Inhibit Mode switch. Refer to Figure 1-2,
, for the location. The Inhibit Mode switch is recessed to prevent
it from accidentally being switched.
The Inhibit Mode switch should be in the
Default
position when normal power inhibit switch
functionality is desired. If the user needs to power on a chassis without a system controller
installed the switch should be in the
Manual
position.
When the Inhibit Mode switch is set to the
Manual
position, the power supplies are enabled, and
you can use the Inhibit signal (active low) on pin 5 of the Remote Inhibit and Voltage Monitoring
connector to power off the chassis. To remotely power off the chassis, connect the Inhibit pin
(pin 5) to a Logic Ground pin (pin 1 or 9). As long as this connection exists, the chassis will
remain off (standby); when you remove this connection, the chassis turns on.
Note
For the Remote Inhibit signal to control the On/Off (standby) state of the
chassis, the Inhibit Mode switch must be in the
Manual
position.
PXI_CLK10 Rear Connectors
There are two BNC connectors on the rear of the NI PXIe-1082DC chassis for PXI_CLK10. The
connectors are labeled IN and OUT. You can use them for supplying the backplane with
PXI_CLK10 or routing the backplane’s PXI_CLK10 to another chassis. Refer to the
section of Chapter 1,
, for details about these signals.
PXI Express System Configuration with MAX
The PXI Platform Services software included with your chassis automatically identifies your
PXI Express system components to generate a
pxiesys.ini
file. You can configure your
entire PXI system and identify PXI-1 chassis through Measurement & Automation Explorer
(MAX), included with your system controller. MAX creates the
pxiesys.ini
and
pxisys.ini
file, which define your PXI system parameters. MAX also provides an interface
to route and reserve triggers so dynamic routing, through drivers such as DAQmx, avoids
double-driving and potentially damaging trigger lines. For more information about routing and
reserving PXI triggers, refer to KnowledgeBase 3TJDOND8 at

.
The configuration steps for single or multiple-chassis systems are the same.
