Counter Signal Routing

The NI-9361 has flexible signal routing features. The input signals to the counters can be routed from any of the eight digital input terminals. You can change the signal routing by configuring the counter properties.

The software routes certain digital input signals to each of the counters by default. The following table shows the default routing for counter signals.
