Configuring Switch Terminal Blocks and Topologies

Switch terminal blocks delivered with NI systems are configured to associate with the switch modules specified in the system design. Some NI switch terminal blocks used with NI PXI switches cannot be detected by software. For example, the TB-2640B switch terminal block used with the PXIe-2532B switch module cannot be detected by software. Test System Maintenance Software may not operate correctly if you alter the configurations of these undetectable switch terminal blocks in NI MAX. Enabling Configuring Switch Terminal Blocks and Topologies ensures that the configuration of these switch terminal blocks matches the original system design.

Note This setting only applies to the following switch terminal blocks that cannot be detected by software, which are associated with the PXIe-2532B device. If your system does not contain any of the following switch terminal blocks, you do not need to enable this setting,
  • TB-2640B
  • TB-2641B
  • TB-2642B
  • TB-2643B
  • TB-2644B
  • TB-2645B
  • TB-2646B
Note Continuity tests for the PXIe-2532B will result in a failure when the topology of the switch terminal block does not match that of the switch terminal block specified in the original system design.

When you enable the Configuring Switch Terminal Blocks and Topologies setting, Test System Maintenance Software restores the switch terminal block to the configuration originally specified in the system design in NI MAX. To enable this setting, complete the following steps.

  1. Go to the Settings page in Test System Maintenance Software and click the Configuring Switch Terminal Blocks and Topologies checkbox.
  2. Run the Verify Components operation to verify that Test System Maintenance Software detects the terminal switch block.
Note You must run the Verify Components operation after enabling this setting for the changes to take effect.
