0 DAQman Posted January 12, 2023 Share Posted January 12, 2023 I suspect there's a problem with your device. Close TracerDAQ Pro and run InstaCal. Select the device and then choose Test->Digital. Run the test and make sure the ports pass. If they do, try Tracer DAQ Pro once more. An alternative solution is to use the DAQami program to test the device. https://www.mccdaq.com/downloads/DAQami/daqamisetup.exe Best regards, John Link to comment Share on other sites More sharing options...
0 Rod Dewey Posted January 26, 2023 Author Share Posted January 26, 2023 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?

0 Fausto Posted January 26, 2023 Share Posted January 26, 2023 Hello @Rod Dewey. Please test your USB-1024LS with InstaCal again and remove all wired connections from the screw terminals. Do all four ports pass on the Internal DIO test? With regards to TracerDAQ Pro, I was unable to reproduce your issue. I connected a USB-1024LS to my Windows 11 system and then launched InstaCal first. Once the device was detected in InstaCal, I closed InstaCal and then opened TracerDAQ Pro. I selected eight digital input channels from '1stPortA'. I set the scan rate to 10 Hz. I started the acquisition and toggled the digital input channels. TracerDAQ Pro ran without an issue. I manually stopped the strip chart just under 4 minutes. If your USB-1024LS fails InstaCal's digital test and you are unable to run TracerDAQ Pro for 4 minutes at a scan rate of 10 Hz, then you may have an issue with your device.

0 Rod Dewey Posted January 27, 2023 Author Share Posted January 27, 2023 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 Link to comment Share on other sites More sharing options...

Also, test the module with a different PC. What is the module's factory serial number, either shown in InstaCal or a label on the backside?

0 Rod Dewey Posted January 30, 2023 Author Share Posted January 30, 2023 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 Link to comment Share on other sites More sharing options...
0 Fausto Posted January 30, 2023 Share Posted January 30, 2023 Hello @Rod Dewey. Thank you for the serial number. I am unable to find an invoice date for that serial number, which indicates that the module is out of warranty. Please disconnect all of your wiring to the USB-1024LS module and run the DAQami application again, with the eight digital inputs enabled and the 4 Hz sampling rate or faster. Does DAQami crash without any connections to the module? If it does, then your module is damaged and should be replaced. MCC does not repair the USB-1024LS modules. If DAQami does not crash, then you should examine your wiring and test one digital input at a time. Regards, Fausto Link to comment Share on other sites More sharing options...

0 Fausto Posted February 3, 2023 Share Posted February 3, 2023 Hello @Rod Dewey. With all signal wires removed from the screw terminals, the USB-1024LS should not crash a software, if functioning correctly. Which version of Windows OS are you running? Which version of InstaCal and DAQami are you using? Recommend using the current versions. https://www.mccdaq.com/Software-Downloads Please test your USB-1024LS module with another Windows OS system (version 10 or 11) and without any signal connections. This module is not repairable by MCC, so if it continues to fail, then you should consider replacing the module. Regards, Fausto Link to comment Share on other sites More sharing options...

0 Fausto Posted February 7, 2023 Share Posted February 7, 2023 Reference the following tech note link for a low pass filter schematic. https://www.mccdaq.com/TechTips/TechTip-2.aspx Link to comment Share on other sites More sharing options...
0 Rod Dewey Posted February 9, 2023 Author Share Posted February 9, 2023 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 Link to comment Share on other sites More sharing options...
