4relind dry contact


  • Is "inrd" command only for the opto isolated contact and not the dry contact ?  

    If I have the common and 10k open, and run "resrd" I can see the change by opening and shorting the 10k to common  (jumper is 2-3)

    Is there a command I am missing to swap it from 10k to dry contact ?  I thought for the 16universal you had to make selection to change from 10k to dry contact.  

    The opto isolated works when I have the jumper in 1-2 and get feedback with the in1 light.  

    thanks!!



  • The "inrd" command will read both opto-isolated and dry contact. The resistor selection is made with a jumper, and the 10k and dry contact have the same jumper position.

     


  • I have not been able to get inrd to work with the dry contact.  It works for the opto isolated.   I swap the jumper and try the dry, I can not get a reading on dry.  When it is jumpered for 2-3 "resrd" functions as you would expect from opening and closing.  Behavior is the same on all 4 channels  

     

    These boards are v2.0 on FW 1.1 

    Not really a big deal on these, I can use the opto instead.  I just found that when I was doing some testing for a project.   


  • Are you sure you connected the dry contacts to the right contacts on the 3-pin connector?

    The last is FW 1.5, you might consider updating the firmware: https://github.com/SequentMicrosystems/4rel4in-rpi/tree/main/update

    Make sure no one accesses the I2C port during update, and if it fails before reach 100%, rerun it until complete  


  • FW update fixed it!

     

    Thanks!
