Independent

When the PXI-2530 and SCXI-1130 are configured with software as

independent switch banks, you can control the state of any relay on

the module. Use this mode for custom applications, where the banks

of 16x1 multiplexers can be combined to form other multiplexer

sizes or operate independently.

Automatic Scanning

The PXI-2530 and SCXI-1130 are able to maximize throughput in

automated test applications by the use of scanning. Scanning

improves throughput by downloading a list of up to 32,000

connections to the switch modules and cycling through the list using

an event (trigger) without any interruption from the host processor.

Scanning is most efficiently accomplished by mating the PXI-2530 or

SCXI-1130 with an instrument, such as the NI PXI-4070 FlexDMM,

that issues a trigger after each measurement.

SCXI Module Control

Every SCXI switch system requires an external switch controller.

The switch controller uses the digital communications bus on the

SCXI chassis to control the switch circuitry. An NI 4021 Switch

Controller, available for both PCI and PXI, is the recommended

SCXI switch controller.

Signal Connections

Terminal blocks provide screw terminals, spring terminals, or ribbon

cable terminals for easy connections. The terminal blocks for the

SCXI-1130 are twice as deep as traditional SCXI terminal blocks,

such as the SCXI-1300 and SCXI-1303.

Software

All National Instruments PXI and SCXI switch modules are shipped

with NI-SWITCH, an IVI-compliant driver offering complete

functionality for all switch modules. For additional assistance in

configuring, programming, and managing higher-channel-count

switching systems, NI Switch Executive software offers an easy-to-

use, intelligent switch management and visual routing environment.
