2. Mounting the reader:
Find a suitable location to anchor the reader mounting bracket. The reader may be mounted vertically or
horizontally.Seerecommendedorientation.Themounting ofthereaderdoesnotrequire ajunctionbox.However,

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:
TheMR-20reader providesa 12-keykeypad forPINentry. Theflex tailof thekeypadis connectedto theelectronic
boardviaaZIF(zeroinsertionforce)connector.Thecontactsareengaged/disengaged byamovingslide.Caremust
beexercised when connecting anddisconnecting the keypad. Whenconnecting the keypad tothe 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.
CONFIDENTIAL: For installation and maintenance use only. DO NOT distribute.

6. TTL Interface:
The TTL interface has the standard 5-wire interface widely
used in the access control application. In addition, an input
to control the buzzer is provided. Cable with minimum of
24AWG wires should be used.

7. Grounding the Reader:
Toavoid havingESD(electrostaticdischarge)interferingwiththeoperationofthereader,thereadercasingshallbe
grounded.Thiscanbeaccomplished bytyingthemounting brackettoearthgroundlocally (e.g.groundedconduit).
8. DIP switch/Jumper setting:
TheDIPswitch/jumperontheMR-10/20readersareusedtoselect
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. Refer to the format specification for detail. The
settingsareforSTANDARDmodelsONLY.
5. Weather Proofing the Reader:
Thereaderisratedtooperateoveranextendedtemperaturerange.
However,ifthe readerisexpected tobeexposed toweather,the
weatherized option (-OW) must be ordered. The option is imple-
mented in two parts. With the (-OW) option, the electronics is
conformalcoated againstmoisture. Atube of dielectricgrease is
suppliedfortheinstallertocoatfieldconnectionstocompletethe

9. MR-10/20 Standard Format Code Summary:
Thefollowing formats are supported instandard models (300x2-0000/310x2-0000).
Unlessotherwiseindicated, theLED inputlinecontrols bothLEDs (low=green,high=red);the BUZZERinput
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.

10. Keypad Data and Tamper Monitor Signalling:
Keypad data and tamper monitor status are transmitted on the data lines as 8-bit blocks. They are encoded and
sentusingthesame signalingmethodas selectedforthe carddataoutput(clock/data ordata1/data 0). Carddata,
tamper status data, and keypad data blocks are separated by a minimum of 100 milliseconds. See following for
codes: 10110000 - 0 (ASCII '0', odd parity, MSB first) 00110001 - 1 (ASCII '1', ...)
00110010 - 2 (ASCII '2', ...) 10110011 - 3 (ACSII '3', ...)
00110100 - 4 (ASCII '4', ...) 10110101 - 5 (ASCII '5', ...)

00111000 - 8 (ASCII '8', ...) 10111001 - 9 (ASCII '9', ...)
00101010 - * (ASCII '*', ...) 00100011 - # (ASCII '#', ...)
11010011 - SAFE (ASCII 'S', ...) 01010100 - ALARM (ASCII 'T', ...)
11. Reader Verification:
The reader performs a self-test when power is first applied to the unit. If power-on test is successfully completed,
ThereaderwillturnonbothLEDsforapproximately1secondandsoundthebuzzerfor1shortbeep.Thenthereader
is ready for normal operation.
If further verification of the reader hardware is needed, the reader may be temporarily set to format T. With this
format selected, the reader will read and verify standard ANSI track 2 encoded card. If no read error is detected,
the green LED will flash. Otherwise, the red LED will flash and the buzzer will sound two short beeps to indicate an
error.TheLEDinputcanbeusedtoverifytheLEDfunction;andthebuzzerinputforthebuzzerfunction.FortheMR-

12. Maintenance:
Thereadersaredesignedtoprovidecontinuousservicewithminimalroutinemaintenance.However,contaminants
(such as magnetic oxides from badges and dirt) tend to accumulate on the read head. Without regular cleaning,
these contaminants will shorten the read head life and increase the probability of card read error. A maintenance
scheduleshouldbedevelopedbase onthecardreader environment (dirtyorclean)and theusagefrequency(light
traffic or heavy traffic). Extreme case may require daily cleaning.
