The only info I found about the use of the PicoLog 1216 Digital Outputs was in the Programmers Guide manual.
Let me know if there is more offered somewhere hidden in the Support part of your website.
Is there no way for PicoTech to include this in the PicoLog data logging software?
It could be in the same style as the existing Trigger menu: choose trigger source (channel #), threshold etc. Can't be that difficult and it would absolutely enhance the versatility of the product.
