C Series, M Series, and TIO Counter Internal Routing Diagram

The following figure shows the routing for DAQ devices that use the TIO counter/timer such as 66XX devices or for devices that use the STC2 timer, which is on M Series devices and the CompactDAQ chassis.

You can use any PFI line on your device. However, there are preferred PFI lines that do not require extra internal resources when used. Refer to Routing Considerations for Timing I/O Devices for additional information.
