You can engage the DM-20 with BioStar 2 and control the Wiegand reader’s LED, Buzzer, Tamper, and more. The DM-20 can detect 4 states such as ON, OFF, Open, and Short Circuit by using the Supervised Input port. With the ‘Trigger and Action’ function from BioStar 2, you can preset the operation to perform when the DM-20 detects a state of Open or Short-Circuit.

Supervised Input Principal and Connection The Supervised Input detects the voltage flow on the circuit and supervises the input device based on 4 states (Open, Short-Circuit, ON, OFF).
BioStar 2 and DM-20 DM-20 added to the BioStar 2 can monitor the device or switch’s open and short-circuit sates. You can configure the ‘Trigger and Action’ and send out a preset signal or send an e-mail to the administrator when the DM-20 detects a certain state.
System Diagram The DM-20 can configure doors in numerous ways. You can connect 2 Wiegand readers to 1 DM-20 and easily control many doors by connecting the slave device and the DM-20 in daisy chain via RS- 485. Knowledge Center - http://kb.supremainc.com/knowledge/...
