Issue Details

I need to create a very large multiplexer switch, but no module exists that is big enough. Can I cascade multiple switches or somehow combine multiple switches into one large switch?


NI's recommendation for large switching applications is NI Switchblock. This hardware is very scalable and simple to implement in software. If your application requires a switch larger than a single module can provide, this will be the best solution.

While this functionality may be achievable by cascading multiple switches, this solution would be unreliable and far more complex than using SwitchBlock hardware.
