Information subject to change without notice.
1. General:
The MR-10/20 family of magnetic stripe card readers are designed for reading standard or high-coercivity magnetic
stripe cards. The MR-20 also provides a 12-key keypad for PIN entry. The MR-10/20 provides a TTL interface. 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 MR-20 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.
