Interface Descriptions
Wiegand Output: Common data interface in an access control system consisting of D0 and D1 Wiegand communication
lines. For more information see this basic reference: https://en.wikipedia.org/wiki/Wiegand_interface
TTL: Serial interface to enable bi-directional communication between the OEM 200 and the host device. For more
information see this basic reference: https://en.wikipedia.org/wiki/Universal_asynchronous_receiver/transmitter. The OEM
200 internally utilizes 1kΩ pull-ups on the TTL interface.
General Output: Digital output that is normally low and goes high indicating that the OEM 200 successfully read a card. The
Host device can use this signal to sound a buzzer or turn on a light.
