### Device wiring

#### Network (PoE) / RJ45 (Non-standard PoE) <a href="#toc228262228" id="toc228262228"></a>

Standard RJ45 interface is for the connection with PoE switch or another network switch. PSE shall comply with IEEE 802.3af (PoE) and its output power not less than 15.4W and its output voltage is not less than 50V.<br>

#### Power / Custom input configuration interface / Wiegand <a href="#toc228262229" id="toc228262229"></a>

The power interface of Door Station connects to 12V DC power.

The interface can be connected to one IC/ID card reader or be used for reading the information of built-in card reader.

{% hint style="info" %}
Note: Door Station can only be connected to one card reader or management device at a time.
{% endhint %}

#### RS485 / Switching Value Output

Enable to connect equipment with RS485 interface.

Connect to the lock module (an independent power supply is necessary for the lock).

{% hint style="danger" %}
Warning!

1\. When connecting to an inductive load device such as a relay or electromagnetic lock, you are recommended to use a diode 1A/400V (included in the accessories) in anti-parallel with the load device to absorb inductive load voltage peaks. The intercom will be better protected in this way.

2.The load current of the relay cannot be greater than 2A. See attached picture for more details.
