Set bus address with BALTECH AdrCard

To switch the host interface of an ACCESS200 reader from Wiegand to the bus protocol OSDP (or a custom bus protocol), you need to assign a bus address to each reader. One way of doing this is BALTECH AdrCard, available in our online shop.

AdrCard vs. configuration

AdrCard enables the bus protocol and lets you set an individual bus address. Deleting the address will reenable the Wiegand protocol.

The bus protocol can also be enabled via the reader configuration. In this case, the following applies:

  • The address set with AdrCard always overrides the address from the configuration.
  • Deleting the address set with AdrCard will reactivate the address from the configuration.

Set bus address

Set the address before deploying the configuration. If the reader is already configured, the reader housing must be open (i.e. trigger a tamper alarm).

  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. To confirm, the reader repeats the entire signal sequence.

Delete address

If the reader is already configured, the reader housing must be open (i.e. trigger a tamper alarm).

  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, indicating that the address has been deleted.
  5. Remove the card from the reader.
  6. To confirm, the reader will repeat the start signal and the dissonant beep.

Check address

You can do this at any time, no matter if the reader housing is open (i.e. triggers a tamper alarm) or closed.

  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.
