Issue Details

How can I find out how many counters are there in my DAQ device?

Solution

The type of DAQ device varies the number of counters, and how they can be configured.

cDAQ Device

The counters in cDAQ devices can be found in the device specifications under the title: General-Purpose Counters/ Timers. An example of this can be seen below for the 9171 Chassis:

 The maximum a chassis or individual card can hold is four counters for the cDAQ product line. To add more counters, you would need a specific counter card such as the NI-9361. To look at all of the counter modules and devices see the following page: Counters and Timers

USB DAQ Device

The counters in USB DAQ devices can also be found in the device specifications under the title: Counter or Counters. An example of this can be seen below for the USB-6001 Device:
