  1. Hi,nt I noticed this circuit in your guide but could not see how-to implement this in my circuit. i am going to try to debounce the contacts using a Schmitt trigger chip
  2. Hi, The serial number is 153DF7C I logged with DAQami at 4Hz and it crashed after 8723 readings Perhaps the test Hardware- wiring enclose is cause a spike from the switching . Should I add a capacitor across the supply pins 29-30 Or are there any other recommendations Thought I sent the above, but I have now run the unit logging at 4Hz and with no switching of the relays it ran for over 4 hours 588800 only stooping on the time out set So i need to de-bounce the contacts Your signal connection guide suggest a low pass filter but not sure how to apply this to my circuit

  5. I have tested the board with no connections and it passes., The only difference with by logging set up is I selected Digital in only With 4Hz it logged 1861 samples before error with 2 Hz 7439 samples with 1Hz 1051 samples
  6. I tried the test but port A fails the test with the hardware connected as this ground all 8 digital inputs of the port . I have not disconnected the inputs to check if it still fails. When logging it works fine for a while then crashes Am I exceeding the sampling speed of the 1024LS?
  7. usb-1024LS fails with error " Error: 2 Dev0 Error: Digital device is not responding." logging on TracerDAQpro - 8 channnels digital in montoring relay switches wired as figure 3.3 of User guide logging at 4 Hz, also fails on 2 and 1Hz
