Single Module Scanning

NI-SWITCH supports single module scanning for both PXI and SCXI switches in NI-SWITCH and NI-DAQmx.

NI-SWITCH

To scan individual switches using NI-SWITCH, you can write a scan list or use the programming examples.

NI-DAQmx

For information about developing a single switch scanning application using NI-DAQmx, refer to the NI-DAQmx Help.

Determining the Scanning Setup

The scanning setup is dependent on your hardware and triggering scheme. Based on your hardware and triggering scheme requirements, choose one of the following scanning setups:

PXI Scanning—Synchronous

• Setup 1—Using Internal PXI Trigger Lines
• Setup 2—Using AUX Trigger Cable Connected to Front of PXI Switch

PXI Scanning—Handshaking

• Setup 3—Using Internal PXI Trigger Lines
• Setup 4—Using AUX Trigger Cable Connected to Front of PXI Switch

SCXI Scanning—Synchronous

• Setup 5—Using SH9MD-AUX Cable
• Setup 6—Using AUX Trigger Cable Connected to the Front of the SCXI Switch
• Setup 7—Using Internal PXI/SCXI Trigger lines

SCXI Scanning—Handshaking

• Setup 8—Using SH9MD-AUX Cable
• Setup 9—Using AUX Trigger Cable Connected to the Front of the SCXI Switch
• Setup 10—Using Internal PXI/SCXI Trigger lines
