When you construct BioStar 2 with 1st generation entry level devices and 2nd generation devices together, you can meet a sync error issue and cannot operate the system correctly.




As you know, 1st generation entry level devices and 2nd generation devices have different capacity in number of users, access group, access level, floor level and other features.

Note: From BioStar 2 v2.7.3, max access group, max access level, max floor group, and max floor level support up to 2048.


If you enroll and create more than maximum number of entry level devices’ capacity, BioStar 2 cannot get in sync with entry level devices because the current setting exceeds the ability of device.


In this case, you have two options to resolve the issue.

Option 1. Reduce current usage of users, access group, access level, floor level as your entry level devices’ limitation.

Option 2. Replace all your current 1st generation entry level devices to 2nd generation devices to keep your maximum usage.
