Legacy Programming

If you have an existing application and your switches are configured under Traditional NI-DAQ (Legacy) Devices in MAX, the resource name suffixes remain valid. This book covers each switch compatible with this extended resource name syntax and lists the valid channels for each operation mode.

Note  This information is intended for those who are modifying existing applications that use this extended resource name. These suffixes will be rendered obsolete in a future release of NI-SWITCH.

SCXI Switch Modules

The syntax for the resource name of an SCXI switch module that uses a suffix is:

SCXI[chassis ID]::slot number::[suffix]

where the possible suffixes are INDEP, MATRIX, SCANNER, and INSTR.

PXI Switch Modules

The syntax for the resource name of an SCXI switch module that uses a suffix is:

PXI[bus number]::[device number]

where the only suffix is INSTR.
