The Wiegand Interface Module (WIM) is an add-on device available from ISONAS.


  • It allows connecting an external, Wiegand-only reader to the serial port on an RC-03.
  • A credential presented on the Wiegand-only reader is treated like a presentation on the RC-03.
    • Allows for in/out style doors.
  • Allows for two-factor authentication on an RC-03 using 3rd party devices.
    • Factor 1 can be a read from a credential on RC-03.
    • Factor 2 could be a read from a Wiegand fingerprint sensor.
    • Factor 2 could be a read from a Wiegand license plate reader.

The main function it is used for is in/out style doors. The door remains locked at all times, a valid badge on either the interior reader (RC-03) or exterior reader (Wiegand device) unlocks the door.

To enable this functionality:

  1. Put the RC-03 in server mode.
  2. Open the Reader Commander tool and connect to the device.
  3. Issue a “Set Wiegand” command .
    1. Disable (no WIM support).
    2. Wiegand Raw (WIM support, no bitmasking).
    3. Wiegand w/ HID processing (WIM support, bitmasking applied) – most common setting when using a WIM.
  4. Close Reader Commander and point your reader back to Pure Access (set it into Client Mode).

Once the above is complete your device will support the WIM in Pure Access.
