Answer:
The KR500 E reads standard 125KHz EM proximity cards and key fobs and transmits data using the industry-standard 26-bit Wiegand format. It is compatible with any third-party or ZKTeco access control panel or standalone attendance terminal with a Wiegand input.
The KR500 E serves as a slave reader across various access control architectures:
- Card Compatibility: 125KHz EM proximity RFID cards, tags, and key fobs.
- Controller Compatibility: Interfaces with any ZKTeco multi-door controller (such as InBio or C3 series) or third-party access control panel supporting standard 26-bit Wiegand protocol.
- Wiring Lines: Connects power (DC 6–14V), ground, Wiegand Data0, Wiegand Data1, External LED control line, and External Beeper control line.
