Using Delayed Pulse to Trigger External Hardware

[tystikk]

I have a Labview set up with an 8253 counter chip (PC-1200). I was wondering whether I could just use the delayed pulse example (with the inverter chip)to trigger an external 5v switch. If so, how should I set up the pinouts to achieve the trigger? I am very new to Labview, and any help would be greatly appreciated.

Hello;

the only thing you need to double check before making the counter to switch an external device is if the counter chip will be able to source the necessary current the external device needs to switch.

If counter chip can generate the necessary current, you can certainly do that with the example you mentioned. By using that example, the pulse will be generated on the counter output pin. Refer to the DAQ device Users Manual for more information on pinout.

Hope this helps.

I configured my DAQ environment with the PC1200 card and then wired an oscilloscope to pin 10 (DAC0OUT)and referenced it to pin 11. I was unable to read any voltage. Any suggestions? Thank you for the response.
