Fingerprint scans fail in cold weather. Fix: Ver 485L includes a "cold mode" hidden menu. Press Menu > System > Temp Comp > High Sensitivity. This boosts infrared gain.
RS-485 devices show "Bus collision" error. Fix: Ensure terminating resistors (120 ohm) are installed on the first and last device only. Ver 485L has an auto-termination dip switch #4 – set it to ON on the last device. zktime 50 attendance managment system ver 485l better
