I have Labview 7.1 which means I'll have the most updated Ni-switch. A 421 PCI card is controlling my chassis either through traditional Ni-DAQ or Ni-DAQmx.
My computer has the following: 1. 488.2 GPIB controller 2. PXI - not related for this particular problem 3. NI 421 PCI card 4. SCXI - 1000 chassis 5. SCXI - 1127 Mechanical relay switch that will need to be set up in 16x1 4-wire mux 6. SCXI - 1331 module
- Use the chassis created in DAQmx. - In MAX (SCXI-1127 property) select the SCXI-1331 as the terminal block for the SCXI-1127. - Use the shiping NI-SWITCH example found in: F:\Program Files\National Instruments\LabVIEW 7.1\examples\instr\niSwitch called niSwitch Making Connection on a Switch.vi. - Delete the second connect vi and wait for debounce - Point to your SCXI-1127 (SC1Mod4 for example) - Change the topology to "1127/4-Wire 16x1 Mux" - Check the NI-SWITCH help file (Start>>Programs>>National Instruments>>NI-SWITCH>>Documentation>>NI Switches help) for valid channel names under: NI Switch Help>>Devices>>SCXI-1127/1128>>4-wire 16x1 Topology
