Hello.
I am using a PCIe-6363 with a BNC-2110 board. We are reading two digital inputs simultaneously via User1 and User2. Works great!
Now, I want to add two digital (counter?) outputs with two different frequency for modulation purpose where I can alter frequency and duty cycle.
Is this possible with the BNC-2110 board and the USER-I/O already in use?
If yes, which outputs can I use?
If no, is it possible with a different board? I think the PCIe-6363 is able to provide that.
Thanks in advance!

I managed to add 1 (one!) digital counter output to ctr2 (which is the F OUT on the BNC-2110). Of course, I am not sure, if this is a good/correct output but so far it works.
But I do not know where to find output ctr3 on the BNC-2110 to use as the second digital counter output.

I believe the 2110 seems to be one of those accessories that depending how old it is, it could have different labels in some terminals. Please refer to the following:
What Digital Lines Are Accessible for M Series Devices with BNC-2110?
X Series User Manual - Default Counter Pinouts
X Series and M Series pinouts should be equivalent. The F Out terminal is equivalent to PFI 14, which is the default output of Counter 2. The default output for Counter 3 is PFI 15, which is unfortunately inaccessible with the BNC-2110:
BNC-2110 Installation Guide - Connecting Digital and Timing I/O Signals
However, as long as you use LabVIEW (or LabWindows / CVI), you are not forced to use the default terminal. You can use the Counter Output > Pulse > Terminal with a DAQmx Channel Property Node to explicitly chose any unused PFI (refer to the M Series / BNC-2110n article).
If you don't use LabVIEW (or LabWindows / CVI) you'll need to use a different accessory that gives you access to all the pins like a SCB-68A.
