BR20 Magnetic Card Reader
Installation and Maintenance
1. General:
The BR20 magnetic stripe card reader is designed for reading standard or high-coercivity magnetic stripe cards. The
BR20 also provides a 12-key keypad for PIN entry and provides a TTL interface. The following paragraphs describe
instructions for installing and maintaining the card reader. The BR20 does not support the tamper switch option.
2. Mounting the Reader:
Find a suitable location to anchor the reader mounting bracket. The reader may be mounted vertically or horizontally.
See recommended orientation. The mounting of the reader does not require a junction box. However, rigid conduit
is required for outdoor application. A single gang junction box may be used to provide a transition to rigid conduit.
If a single gang junction box is used, a wall plate (optional) may be used to cover the junction box. The reader is then
secured to the mounting bracket using a screw. Refer to figures for reader dimensions and typical junction box usage.
3. Reader Wiring:
The reader has a RJ-11 modular jack for easy field connection. A short piece of pre-terminated cable is supplied with
each standard reader for field wiring. The pre-terminated cable has nonstandard color. Refer to pin number if the pre-
terminated cable is not used. Cable with wires of 24AWG or larger are recommended for field wiring.
4. Connecting the Keypad:
The BR20 provides a 12-key keypad for PIN entry. The flex tail of the keypad is connected to the electronic board via
a ZIF (zero insertion force) connector. The contacts are engaged/disengaged by a moving slide. Care must be
exercised when connecting and disconnecting the keypad. When connecting the keypad to the board, open the slide
as shown. Insert the electronics into the housing and insert flex tail in the ZIF connector. Then, close the slide to engage
the contacts. To disconnect the keypad, follow the previously described steps in reverse.
5. Weather Proofing the Reader:
CONFIDENTIAL: For installation and maintenance use only. DO NOT distribute.

8. DIP Switch Setting: The DIP switch on the BR20 reader is used to select a preset format, the functions for the LED and buzzer, and the output signal format, etc. The preset format determines how the card is interpreted. Refer to the format specification for detail. - Page 3 9. BR20 Standard Format Code Summary: The following formats are supported in standard models (31002-8000/31012-8000). Unless otherwise indicated, the LED input line controls both LEDs (low=green, high=red); the BUZZER input controls the buzzer (low = activate); a good read is signaled by a flash of the green LED; a bad read is signaled by a flash of the red LED and a double beep of the buzzer.
