Set a bus address with BALTECH AdrCard

To activate a bus protocolcall_made on the readers, you need to assign a bus address to each of them. Typically, you need to do this when switching ACCESS2xx readers from Wiegand protocol to OSDP.

The easiest approach is to use a BALTECH AdrCard that you can order from us.

AdrCard vs. device settings

Alternatively, you can enable OSDP by creating device settings. This is the way to go if you want to change the default parameters or want to set a fixed bus address on all your readers.

Set address and activate bus protocol

Do this before deploying a configuration with project settings. As soon as a reader has project settings (and thus a Config Security Code) deployed, you need to open the reader housing (i.e. open the tamper switch) to set a bus address.

Here's a short video showing the process. Below, you'll also find a textual description.

  1. Connect the reader to your computer. The red LED turns on.
  2. You can assign an address between 0 and 16.
    Start the process by placing BALTECH AdrCard on the reader. The reader emits the following:

    • 1 long beep/yellow LED flash as a start signal
    • 3 short beeps/3 short yellow LED flashes, representing address 0.
    • Up to 16 long beeps/yellow LED flashes, representing addresses 1-16.

    Remove the card after the signal for the desired address.

  3. The reader will repeat the entire signal sequence to confirm the address.

The address is now active, and the reader switches to communication via bus protocol (OSDP by default).

Delete address and switch back to default protocol

This step is needed if you want to change the bus address or switch back from OSDP to the default protocol.

If the reader has project settings (and thus a Config Security Code) deployed, you need to open the reader housing (i.e. open the tamper switch) to delete the bus address.

Here's a short video showing the process. Below, you'll also find a textual description.

  1. Connect the reader to your computer. The red LED turns on.
  2. Place BALTECH AdrCard in front of the reader.
  3. Wait for the start signal and the signals for all 16 addresses.
  4. The reader emits a long dissonant beep/quick yellow LED flashes, representing that the address has been deleted.
  5. Remove the card from the reader.
  6. The reader will repeat the start signal and the dissonant beep to confirm address deletion.

You can now set a new address or use the reader without an address to communicate with the host system via the Wiegand protocol.

Check address

With BALTECH AdrCard, you can check the bus address of any reader in your project.

You can do this at any time, no matter if the reader housing (i.e. the tamper switch) is opened or closed.

Here's a short video showing the process. Below, you'll also find a textual description.

  1. Place BALTECH AdrCard in front of the reader for less than 1 second.
  2. The reader will emit signals indicating its address:

    • 3 short beeps/3 short yellow LED flashes indicate address 0.
    • Up to 16 long beeps/yellow LED flashes indicate addresses 1-16.
    • A long dissonant beep/quick yellow LED flashes indicate that the reader doesn't have an address.
