Your first switching setup.

Find the part number on your module and open the matching product page. Switching includes general-purpose relays, multiplexers and matrices; identify which type you have before planning your signal path.

• Locate the manual and connection diagram for your exact model and revision.
• List the signals and test points you need to connect.
• Check the module specifications against your application, including voltage, current and switching limits.

Plan the route from your instrument, through the switching module, to the device under test. Use the module connection diagram to identify the terminals and channels involved.

• Follow the module documentation for mounting, power and connection requirements.
• Match the pin-to-pin or wired arrangement to your fixture design.
• Check the completed wiring against your planned signal path before applying power.

Choose the software workflow for your setup: Brygga, ASCII commands or a programming API. Use the instructions and command reference supplied for your module.

• Confirm that the software can communicate with the intended module.
• Match the channel identifiers in the software to your connection plan.
• Check the documented initial relay state and how to return to it.

Start with one documented switching operation and a controlled test setup. Verify the resulting connection before adding it to a larger test sequence.

• Check that the intended path changes as expected.
• Check that unrelated paths remain in their expected state.
• Return the module to the documented initial state and record the result.
