Hello,
I have big problem with KNX access control on one hotel. Cards which are programmed and work fine,sometimes stop working after few days,and application then brings back year to 1890.My assumption is thae PC sends wrong date to holders and readers then.But service cards still work. Manufacturer says that they did not have problem like this before.System consists of holders,readers ,central PC where cards are made,and programmer.
When app on central PC is exited and turned on again,and new cards made,they work fine.This problem happen maybe once a month.Its really annoying.
Does anyone have any idea what can cause this type of problem?
