try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio / TV technician for help.

PREFACE
This manual provides detailed information relating to the overall operational, electrical, mechanical, environmental and
functional aspects of the MSR120D. This document should be read and understood prior to initial operation of the
product.
For ease of installation and programming use, we have addressed everything from its attractive features to its various
configurations.
When designing the MSR120D, we selected what we feel are the most useful features and functions. If in some cases
you find that your specific needs differ from our existing products, we welcome your comments and suggestions.
Custom-designed models are also available.
If further questions do arise, please call for technical support, our FAE will assist you in any way we can.

Section 1 -- General Description 2005/2/23
Section 1 General Description
This section presents general information about the basic characters of the MSR120D.
¾Features
The MSR120D provides the following features:
1 Light weight: 120g
2 Compact size: 100L*34W*28H (mm)
3 LED and Buzzer indicators indicate card status
4 Low power consumption
5 Single, dual, or triple track versions allow for reading all types of magnetic cards, including credit cards and
drivers licenses.
6 Firmware download (refer to section 6)
¾Application
This Magnetic Stripe Reader is design to read high or low coercive magnetic cards. It can decode/verify up to 3
tracks of data simultaneously. This product communicates with a host computer or other terminal using a standard
USB interface. Because of the transmitting protocol of MSR120D is more precise, it is suitable for using in
financial industry.
¾Function
Self Test
Whenever the reader experiences a reset cycle, a self-test is performed. The reader will respond with “:” and the
LED will turn green if the entire test is successful. Otherwise, the LED will turn orange and no response will be
generated.
Table 1-1. Self Test
Indication
LED Buzzer Cause Post Condition
Green 1 Beep Test Success Responds with “:”
Orange EEPROM Failed Hang
Orange Internal ROM Failed Hang
Transmission Reset by Hardware
When the reader cannot communicate with the host, user can set the switch S1-1 on and power on the reader. The
reader will beep twice and response the baud rate, parity, CTS and RTS default setting, but the data inside
EEPROM will not be changed.

Section 1 -- General Description 2005/2/23
Reading
The reader can read magnetic data form any available track encoded per ISO 7810, 7811, AAMVA, CA old DMV,
JIS. The host can request the read data from the reader with commands. For details and examples of commands
and responses, refer to section 4.
Reading Customized Data
The interface can read customized encoded magnetic data. Data integrity is not verified when reading customized
data. Customized data is not formatted into ASCII characters prior to transmission to the host.
Self –Arm Mode
The default reader configuration is the “Self-Arm Mode”, which allows the magstripe functions to run
automatically, reporting magstripe activity to the host without instruction from the host. In the Self-Arm mode, the
reader also can accept commands from host. However, the reader can be configured to only “Host Polled Mode”
by disabling Self-Arm mode. The “Host Polled Mode” allows the magstripe functions to run by commands. The
conditions of indicators when the reader is in Self-Arm mode are shown below.
Table 1-2. Self-Arm Mode
Indication
LED Buzzer Cause
Off Card Swipe
Orange 2 Beeps 1 or 2 Tracks Read Miss
Red 3 Beeps Read Error
Green 1 Beep Read Success
When the reader is in the Self-Arm mode, the green LED indicates the reader is waiting for accepting card. While
card is moving, the LED will turn off. When one or two tracks read miss, the LED shows orange for 1 second and
the buzzer beeps twice. If tracks read error, the LED turns red and beeps thrice. When the reader is in the Host
Polled mode, the green LED keeps flashing.
Transmitting Data Block of Tracks
Each track could divide into 1-3 channels (blocks) for transmission. For example, user could set “Channel A” of
track1 format as: ISO standard card track1 15th-30th characters. If the set data is different from the data after
swiping, the reader will transmit completed data without limitation. The commands of setting channels are shown
in section 5.

¾Communication
The interface receives and transmits serial bit stream at voltage levels compatible with the USB specification.
Transmission Protocol
The user may select from three different protocols: Protocol 0, 1, and 2.
Upon reset, the reader sends the power-on response “:”, depending upon the configuration setting. The reader then
configures itself to the protocol of the first command from the host. From this point on, the protocol is
unchangeable until a reset occurs.
Protocol 0
In Protocol 0, all characters are transmitted and received using exactly the characters listed in section 4. There are
no headers and Block Check Characters (BCC). Protocol 0 presumes no transmission errors. If the host detects an
error, it may request a retransmission.
Table 3-3. Example for Protocol 0
Host Command Reader Response Comment
P Ready to read
^ Reader ACK
Protocol 1
In Protocol 1, all messages are preceded by the ASCII character <STX> and terminated with the ASCII character
<ETX>, followed by a one byte <BCC>. <BCC> is an XOR of the 7 data bits, excluding parity, of each character
in the entire message, including <STX>.
Format: <STX><MESSAGE><ETX><BCC>
where STX=02Hex and ETX=03Hex.

Host Command Reader Response Comment
02h 50h 03h 51h Ready to read
02h 5Eh 03h 5Fh Reader ACK
Protocol 2
In Protocol 2, all messages are preceded by the ASCII character <SOH>, followed by a one byte reader address,
one byte character count and terminated with a one byte <BCC>. The <BCC> is an XOR of the characters (8 bits)
in the entire message, including <SOH>.
Format: <SOH><ADDRESS><00Hex><COUNT><MESSAGE><BCC>
or
<SOH><ADDRESS><00Hex><00Hex><MESSAGE><EOT><BCC>
where STX=02Hex and ETX=03Hex.
Table 3-5. Example for Protocol 2
Host Command Reader Response Comment
01h 00h 00h 01h 50h 50h Ready to read
01h 00h 00h 01h 5Eh 5Eh Reader ACK
The <ADDRESS> field is for a multi-reader system. This function is not currently supported. The recommended
value for this field is NULL (00Hex), however, any value will work.
If the value of <COUNT> fields are zero, an <EOT>, followed by the <BCC>, completes the message. The reader
may, at its option, use NULL for COUNT when transmitting.
For Protocols 1 and 2, if the reader detects an error in an incoming transmission, it will respond with a
“Communications Error” message. If the host detects a transmission error, it may request a retransmission. Both
protocols enforce a 100mSec timeout between characters.
For all Protocols, the host may, at any time, stop/start the reader transmission by using software “handshake”
(DC3/DC1) or hardware “handshake” (if enabled in EEPROM configuration) by controlling the CTS line.

Section 4 – Commands and Responses 2005/2/23
Section 4 COMMANDS and RESPONSES
This section describes the commands and responses available for the MSR120D series. Each item includes the ASCII,
hexadecimal codes and comments paragraph. The comments paragraph provides an explanation of the command. The
letter ‘x’ indicates a variable and the letter 'h' is an abbreviation of 'hexadecimal'.
All readers are capable of communicating in 3 protocols: 0, 1 and 2. If protocol 0 is selected, all commands and
responses are as listed in this section. If protocol 1 is selected, the characters STX, ETX and BCC must be added to all
transmissions. If protocol 2 is selected, the characters SOH, ADDRESS, COUNT and BCC must be added to all
transmissions.
¾Command －Host to Reader
P (50h) ─Ready to Read
Comments
1 Clear buffers
2 Transmit "ACK"
3 Expect for card swipe
4 Transmit "ACK" after card swipe
After an "Ready to Read" command is received and acknowledged, the only valid commands that will be accepted
for execution are: "Abort" <ESC>, "Status" <$> and LED control commands. When the reader is ready for "Read
on Insert", the "ACK" after card swipe will be transmitted after the rear sensor is activated. For read on reverse
swipe, the "ACK" after card swipe will be transmitted after the front sensor is de-activated.
p (70h) ─Ready to Read
Comments
Same as 'P' command, except an extra response " ( " is reported when a media is detected through the read head.
