# Configure OSDP on Access Controller A094/A095

Open Supervised Device Protocol(OSDP) is a communication protocol designed for security and access control systems. Akuvox access controller A094 and A095 can be connected to OSDP card readers for door opening.

> [!NOTE]
> Note
> 
> - A094’s firmware should be 92.30.10.208 or higher.
> - Tested card reader models: HID Signo20 OSDP reader and STid OSDP reader.

## Wiring

Please refer to the [A094’s](https://knowledge.akuvox.com/docs/akuvox-a094-quick-guide-v10) or A095’s quick guides.

For A094, the OSDP card reader should be connected via its **RS485A/B** interfaces.

For A095, it is connected via the **READER** interfaces.

Before getting started, ensure the devices are installed properly and powered on.

> [!NOTE]
> Note
> 
> For A094, one interface supports up to 4 card readers.

## Configuration on the Device Web Interface

Take A094 as an example.

### Set up RS485

1. Use the [IP scanner](/v1/docs/akuvox-ip-scanner) to scan the device’s IP address and enter it in a browser.
2. Enter the username and password to log in. The initials are admin.
3. Go to **Device > RS485** interface. Set **RS485A/B** to **OSDP**.

1. If the OSDP reader is encrypted, enable **Encryption** and enter the **Encryption Key**. Please confirm the key with the card reader service provider.
2. Click **Scan**. A094 will detect the reader and display it after processing is finished.
3. Check the relay to be opened.

1. Click Submit.

After connection, you can click ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-LH66QVKP.png) to view the reader’s information, including device name, address, serial number, firmware, and status.

Then, scroll to the bottom to set up the **Virtual Door Mode**.

- It is disabled by default. In this case, users can ONLY open relays that are checked on both the OSDP setting and [Access Setting](/v1/docs/configure-osdp-on-access-controller-a094#assign-credentials-to-users) interfaces.
- If it is enabled, users can open relays that are checked on the OSDP Setting interface with their credentials, regardless of whether they are checked on the [Access Setting](/v1/docs/configure-osdp-on-access-controller-a094#assign-credentials-to-users) interface.

### Assign Credentials to Users

1. Go to **Directory > User** interface.
2. Click **Add** to add a user or click ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-HLHV9RF4.png) to modify an existing one.
3. Set the private PIN code and/or RF card for the user.

1. Scroll to the **Access Settings** part. Check the relay to be opened by the user.

1. Click Submit.

After configuration, users can use their credentials on the OSDP reader to open the door.

- **Successful door opening**: The card reader shows a green light for 5 seconds, and the buzzer sounds continuously for 3 seconds.
- **Failed door opening**: The card reader shows a red light for 5 seconds, and the buzzer sounds 3 times.
- **Successful connection between A094 and the card reader**: The card reader keeps a blue light.

## Configuration on the Smart Access Cloud

When A095 is connected to the SmartPlus Cloud, you can set the reader on the cloud portal.

> [!NOTE]
> Note
> 
> - The setting is currently only available in **Commercial Projects**.
> - The cloud settings will overwrite the local ones.

1. Log in to the cloud platform with an installer or a property manager account.
2. Navigate to where the device is installed.
3. Click![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-MWFU6Q00.png).
4. Click **Door** and set **Entry/Exit Reader** to **RS485**.
5. Select the RS485 address ranging from 0 to 127 if multiple readers are connected in a daisy chain state.
