Note that

What you need to know before starting "Wireless Door Lock Integration" of CoreStation:


1) Only CSN Cards that types of MIFARE or DESFire can be supported for this function.

2) This feature operates on the basis of related license activation.

3) The supported OSDP version is v2.2 for now.


Below the v.2.9.3 or lower version of BioStar 2, the configuration of the door lock was possible only through physical wiring. Accordingly, for aesthetic reasons or security reasons, the need to introduce a door lock capable of wireless connection has been raised.

To satisfy this market need, Suprema has launched the "Wireless Door Lock" integrated with U&Z.

Basic Concepts

  • Configuration
  • Data Processing Order 
    1) Scan the enrolled card on the Wireless Door Lock 

           2) Send the card data to the OSDP antenna via wireless communication(BLE)

           3) Send the card data to the CoreStation via OSDP

           4) CoreStation compares the received card data and stored card data in it and sends the results to the OSDP                antenna via OSDP

           5) OSDP antenna sends the result to the Wireless Door Lock via wireless communication(BLE)

           6) Wireless door lock displays the results of either Green LED or Red LED depending on the results from                      CoreStation

Note that

When adding the OSDP antenna and Wireless Door Lock in BioStar 2, you can see the icon on each product as below.

  • OSDP Antenna
  • Wireless Door Lock

1) Knob type

2) Handle type

<Feature 4>

When using this new feature, you can use the below functions by setting in BioStar 2 

A. Use the Wireless Door Lock as Entry device or Exit device when configuring the door

Note that 

  • If you select the Wireless Door Lock as Entry device, you SHOULD select the Wireless Door Lock as Exit device.
  • If you select the Wireless Door Lock as Entry device or Exit device, there is NO POPUP for relay settings

B. Set and use Trigger & Action (How to configure Trigger and Action on Setting)

C. Set and use APB function in Zone (How to configure an Anti-Passback)

D. Can use for Access Control 

Note that 

  • Only CSN Cards that types of MIFARE or DESFire can be supported for this function
  • You CAN set the schedule about the set Access Group

<Feature 5>

When using the Wireless Door Lock, the user's card data is encrypted by SCB key and then, the encrypted data is sent to the OSDP antenna. The key is generated automatically when adding the CoreStation in BioStar 2.

Note that

If adding the OSDP antenna on CoreStation normally, the popup for setting SCB KEY in CoreStation is inactivated.

<Feature 6>

When trying to authenticate at the Wireless Door Lock using the CSN card, you can get the below results.

  • If the authentication SUCCEEDS, the Green LED is turned on the Wireless Door Lock 
  • If the authentication FAILS, the Red LED is turned on the Wireless Door Lock 

When receiving New fresh U&Z Devices

1. You should remove the power sticker for cylinders or add battery for the handle,

2. You should Teach :

    - For the handle only the service key, to do it just present the Service Key card in front of the handle,

    - For the cylinder, you will need to teach the service key then the Battery change then the dismount card.

3. On the Module OSDP or WIEGAND or Switching module, you will see a rotary switch, we recomend you to set it on 0 (Home position). Other position could be used for manual setting.


1. You should select the Baud Rate of CoreStation as 115200 about the connected port with the OSDP antenna, if the product set including OSDP antenna and wireless door lock is purchased through Suprema.

Note that

However, if the above product set has been purchased through other roots but not Suprema, you should set the Baud Rate of CoreStation as 9600 about the connected port with the OSDP antenna.


2. You can set the OSDP ID from 0 to 119 per ONE OSDP antenna module.

Note that 

You CAN NOT change the OSDP ID on the OSDP antenna after you add the OSDP antenna to the CoreStation normally.

3. You CAN NOT directly enroll the card to be used by reading the card on the Wireless Door Lock. So you need to enroll the card to be used on the other added device in BioStar 2 in advance and then, synchronize the enrolled card to the CoreStation. 

4. You can check the BATTERY Status of the Wireless Door Lock in the Wireless Door Lock Status of MONITORING in BioStar 2.

Note that 

You can get the changed battery status of Wireless Door Lock whenever the battery status has been changed by selecting options among the 3 types of battery status(Low battery level, Critical battery level and Empty battery) and setting the alert with it at Alert in Settings of BioStar 2.

5. The license purchase unit is based on ONE Wireless Door Lock.
