Step by Step instruction
In this article, we are testing Third Party access controller with some of our card reader type. DHI-ASR1200 and DHI-ASR-1100. Below are the wiring diagram to connect the card reader using Wiegand Protocol:
| Wire Color | Port |
|---|---|
| Red | 12v Power |
| Blue | Case |
| Black | GND |
| White | D1 |
| Green | D0 |
| Brown | LED |
The Operation of LED is controlled by the Access Controller, the LED operation may vary depending on the Access Controller software. The normal behavior, the LED on card reader will turn Green to indicate that card is read and privileged.
1. Wire the Access Controller to 12v DC power supply.
2. Route the interface cable from the reader to access controller device. Refer to the wire diagram above.
3. After wiring the reader and access controller, power up the access controller device.
4. Connect your access controller device to the network and access it from the computer in the local network. Follow the manufacture user guide to setup the controller, create user, assign permission, etc.
5. Once the access controller is configured properly, the reader is ready to be tested. Scan your card and you should hear the beeps. For this example, we wire a LED light indicator to connect to Alarm output interface from access controller. When the card is read and access is permitted, light turns Green.
