MR10/20 Magnetic Card Reader
Installation and Specifications
1. General:
The MR10/20 family of magnetic stripe card readers are designed for reading standard or high-coercivity
magnetic stripe cards. The MR10/20 provides a TTL interface to an access control panel and the MR20
also provides a 12-key keypad for PIN entry. The following paragraphs describe instructions for installing
and maintaining the card reader.
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 small 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 MR20 reader 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.
CAUTION: DO NOT DISCONNECT KEYPAD WITHOUT DISENGAGING THE CONNECTOR!
COFIDENTIAL: For installation and maintenance use only. DONOT distribute.

Dip Switch Settings: The DIP switches (S1 & S3) on the MR10/20 readers are used to select a preset format. This preset format determines how the card is interpreted, the functions for the LED and buzzer, and the output signal format, etc.
