Analog Output Multiple Square Waveforms on NI cDAQ-9174 with two NI 9264

[InfraredLaser]

Hello, 

I am trying to create a program that will allow me to output single square waveforms across multiple analog outputs similar to the Simple FGEN.gvi file given as a tutorial example within DAQExpress. Below is an image of the diagram of the tutorial example:

When I try to add multiple channels (second image below) in the Function Generator.task file i get the following error:

When I remove Output 1 the program runs but it will only output a single waveform to Output 0 where my goal is to utilize all 36 outputs of my two NI 9264.

Here is my hardware specs:

• Windows 10 
• DAQExpress
• NI cDAQ-9174
• 2x NI 9264

Thanks in advance!
