commMode is the Communication mode that will be used when the driver communicates
with the SCXI chassis and modules.
0: Communication mode is disabled. In effect, the chassis is disabled.
1: Serial communication is enabled through a digital port of a DAQ device that is
cabled to a module in the chassis.
2: Serial communication is enabled over the PC parallel port that is cabled to the
SCXI-1200 module.
3: Serial communication is enabled over the PC serial port that is cabled to one or
more SCXI-2000 chassis or SCXI-2400 modules.
4: Serial communication is enabled over the VXI backplane.
5: Serial communication is enabled through a digital port of a DAQ device internally
connected to the SCXIbus of a PXI-1010 chassis.
commPath is the communication path that will be used when the driver communicates with
the SCXI chassis and modules. If commMode = 1, 2, 4, or 5, commPath should be the device
number of the DAQ device that is the designated communicator for the chassis. If
commMode = 3, commPath is the serial port for this chassis. When commMode = 0,
commPath is meaningless.
numSlots is the number of plug-in module slots in the SCXI chassis.
4: For the SCXI-1000, SCXI-2000, and PXI-1010 chassis.
12: For the SCXI-1001 chassis.
24: For the VXI-SC-1000 carrier module.
Note C Programmers—chassisType, chassisAddress, commMode, commPath, and
numSlots are pass-by-reference parameters.
