New User starting with DasyLab 2022 Full Trial and USB-1608G

Question

HI,

I want to use the USB-1608G TMR output pin 53 for some loopback testing of analog and digital inputs.

I may want to also use the pins 46/48 for A0/1 clock-out. 

MCC-DRV does not show the TMR module.

MCC-DRV does not show a module for the clock-out pins, are they programable? 

The USB-1608G does not have counter outputs, only counter inputs.

Any suggestions? Are these pins supported?

See pic below.

Hello @Gary L.

The TMR (Timer Output) terminal on the USB-1608 Series uses the MCC-DRV - Counter Output module in DASYLab.  In the example below, I wired the TMR screw terminal to CTR0 (input) and CH0H (analog input), and wired GND to CH0L (analog input in differential mode).    Usb1608_Timer_Output.DSB

The AOUT0 and AOUT1 terminals (analog outputs 0 & 1) use the MCC-DRV - Analog Output module in DASYLab.

Hi Fausto,

The example you provided is for the USB-1608GX-2A0, I have the USB-1608G. I had to modify the example you sent.

The AOUT0 and AOUT1 terminals (analog outputs 0 & 1) use the MCC-DRV - Analog Output module in DASYLab.

These pins are not supported in the USB-1608G version.

"Two analog output connections (AOUT0, AOUT1) – USB-1608GX-2AO only" See USB-1608G-Series.pdf pg. 12

For my modified example,  I wired the TMR screw terminal to CTR0 (input) and DIO0 and used the meter and chart as in your example.

I used a Digital Input in SE mode. Not sure what sampling rate to use.

I get this block error now:

To summarize, If I understand correctly the TMR pin is enabled using the Counter Output Module.

Hi @Gary L.

Sorry for the confusion with the different models in this series.  The 'USB-1608G' does not support an analog output subsystem.

With regards to your error, in my screen capture below, I have an Analog Input module connected to the Y/t Chart.  Note the Analog Input module is configured to output a block of 100 samples each time.

You will need to change the Timebase Settings for the Digital Input module.
