37-Pin DSUB Signal Connections for Counters

The following table lists the default input terminals for various counter measurements for devices that use the 37-Pin DSUB connector such as the NI 6010, NI 6154, and NI 623X. You can use a different PFI line for any of the input terminals. To change the PFI input for a measurement, use the NI-DAQmx channel attributes/properties.
