I have a problem with Passpoint plus access control system. I have two access points on a single DCM that will not respond to any cards. One day it worked and the next they didn't. The only event that happened between that time was a Card EXP Counts Back UP. I can manually grant access to the door from the computer, but when I try any access card the access point beeps, but nothing happens and no log entry is created in the event log. All the settings for the DCM and the access points are setup the same as the others on the system. I have deleted the DCM and re-enrolled it but still the same problem. Is there a process to reload all the cards for that DCM. I noticed there is an upload command for the cards. Should I try to upload the cards back to the MLB? Will that erase any information?Any advice would be greatly appreciated. Thanks
