SUPREX® II Remote Unit Dip Switch Setting
Switch #2 - On = Door Strike Relay does NOT follow LED status.
Off = Door Strike Relay follows status of LED.
Switch #6* - On = Bit mode (Noise filter off) for keypad applications.
Off = Noise filter mode, standard reader applications
(Default setting)
SUPREX® II Central Unit Dip Switch Setting
Switch #3 - On = Inverts idle on MagStripe version
Off = Normal operation of MagStripe version
Switch #4 - On = Inverts Aux 2 Relay Status
Off = Normal operation
*Not active on versions earlier than 2-1-2003
When wired and powered up corectly, LEDs on
Remote and Centrol will blink 5 to 10 times per
second. When there is a problem with
communication between the Remote and
Central, the LED on the Central will blink 2
times per second and the Remote LED
will not light at all.

Weigand Controller
• The Controller's LED signal changes the state of the Door Strike relay.
• The Controller's Supervised Alarm Input monitors the state of the End-of-Line Device.
• If loss of power or communication occurs, the Supervised Trouble Input will activate.
• The Programming Resistor 1 is used to calibrate the Remote Unit's Alarm Input 1 Sensor.
(Any End-of-Line value from 100 Ω to 20KΩ can be monitored by using the same value for the Programming Resistor.)
