The MINI MICR USB With Optional 3-Track MSR is both a MICR (Magnetic Ink Character
Recognition) Check Reader and an MSR (Magnetic Stripe Reader).
The MICR Reader, in a typical application, reads the magnetic data encoded on the bottom of
checks or magnetic stripe cards and transmits this data to a Host device. The Host device then
uses a specific authorization or verification process to validate a business transaction.
The use of the MICR Reader improves accuracy and speed because there is no manual data
entry; therefore there are no keying errors or unwanted delays.
The MICR Reader will communicate with the Host system using a standard USB interface. The
driver will emulate a serial port on the host PC. All data is transmitted as ASCII characters (See
Appendix D).
FEATURES
• Available with MICR Reader only or with 3-Track or 2-Track MSR.
• Three track MSR autodiscriminates different card formats: ISO (International Standards
Organization), CDL (California Drivers License), or AAMVA (American Association of
Motor Vehicle Administrators).
• Small footprint.
• Automatic parsing of MICR fields: transit, account, etc.
• Extensive list of formats to transmit MICR data.
• Optional error/status reporting for check reading.
• Reads E13-B and CMC-7 MICR fonts.

MINI MICR USB with 3-Track MSR
USB DRIVER INSTALLATION
When using the USB version of the Mini MICR, you must install the appropriate files on your
computer. The USB devices will only operate on computers with Windows 98/ME/2000/XP
operating systems.
The USB driver files are available in two forms:
- On a CD (p/n 30035077)
- From the MagTek web site (www.magtek.com) (p/n 99510038). (The files on the
web site are provided in a self-extracting zip file. Run the application and unzip the
files to a temporary folder on your local disk drive.)
If you have the CD or after you have extracted all the files, proceed with installation steps below.
These steps will only have to be performed the first time you attach the device.
1) After the USB cable and the power adapter have been connected to the device and to the
PC, Windows will indicate that it found new hardware and will show the Mini MICR
device has been attached.
2) You will then be prompted to use the USB Wizard to install the device driver and other
appropriate files.
3) When prompted, ask the Wizard to search for a suitable device driver.
4) If you have the MagTek USB drivers on a CD, specify the CD drive as the location of the
driver. If you used the web installation, you many use the Browse button to specify the
location to where the files were extracted.
5) After you locate the requested INF file, click Open.
6) After all of the files have been installed, click Finish.
After the files have been installed, any application program can communicate with the Mini
MICR just as if it is attached to a regular RS-232 COM port. If your application can
automatically detect the available COM ports, the newly installed USB device will be shown as
one of the available COM ports (e.g., COM5).
If your application does not support COM port selection, you can determine the COM port
number by using the device manager. This can be done by right-clicking on the My Computer
icon on the desktop; then select Properties. In Windows 98/ME, click the Device Manager tab;
in Windows 2000/XP, click the Hardware tab, then Device Properties. When the Device
Manager window opens, click on the plus sign next to Ports (COM & LPT). The new device
will be shown in the list with its COM port identified.

SECTION 3. OPERATION
This section contains check and card reading procedures and LED indicator states.
CHECK READING PROCEDURE
1. Orient the check so the MICR line is down and the printed side faces the center on the MICR
Reader as shown in Figure 3-1.
Figure 3-1. Check Orientation
2. Drop the check so the leading edge is in the open slot.
3. When the MICR Reader detects the presence of the check, the motor will turn on. At this time
gently urge the check forward until the unit grabs the check. When this happens, release the
check. The check will then be transported around the check path and will exit through the other
side.
4. After the check is read, the MICR Reader will transmit the data as specified by the parameters
described in Section 4, Commands.
CARD SWIPE PROCEDURE
The card may be swiped through the MSR in either direction, but the magnetic stripe must be oriented in
only one direction as shown in Figure 1-1. The MSR will transmit raw card data (“as is” on the card) for
all tracks that have been enabled using the HW (Hardware) command (Section 4, Commands).
The MSR is capable of reading ISO, AAMVA, and CDL encoded cards. The MSR will autodiscriminate
all the card formats when the ID Card Decoding option is enabled using the HW (Hardware) command
(Section 4, Commands).

SECTION 4. COMMANDS
This section describes the use of commands and programmable options available for the MICR Reader.
Note
All options described below can be factory set as specified by the user when
ordering.
To execute the MICR Reader commands, either one of two methods is required: Insta-Change checks or
the MICRbase Setup Program for Windows.
INSTA-CHANGE CHECKS
The first method is the use of Insta-Change checks, which is a more practical way of setting up the
MICR Reader for most applications. The Insta-Change check is a MICR encoded document that
contains commands and options used to reset the parameters of the MICR Reader. Multiple
commands and options may be contained on one Insta-Change check. When used, the InstaChange checks are run through the MICR Reader the same as a standard check, and the options to
be used are automatically selected. To obtain Insta-Change checks, notify a MagTek
representative and specify what options will be used. To operate Insta-Change checks, install the
MICR Reader as described in Section 2, and watch the LED indicator. When the Insta-Change
check is run through the MICR Reader and read successfully, the LED indicator will blink green.
If the LED indicator turns red, the read is not successful. Try again or use a different InstaChange check.
MICRBASE SETUP PROGRAM FOR WINDOWS
The MICRbase setup program (P/N 22000021) allows the user to control all the programmable
options available in the MICR Reader.
The program provides a graphical, user-friendly interface that hides the complexities involved in
manually entering MICR commands. The user is no longer required to know the specific commands
or the detailed data associated with each command. However, the program still allows manual entry
of commands for advanced users. For more detailed information refer to the MICRbase Setup
Program Reference Manual (P/N 99875102).
The MICRbase setup program may also be downloaded from the internet at www.magtek.com under
Software/Demo Programs.
MAGTEK DEVICE DRIVERS FOR WINDOWS
For Windows applications, the MagTek Device Drivers for Windows (P/N 30037385) are available
to simplify the programming of the MICR Reader. The drivers are easy to install, and they facilitate
the execution of MICR Reader commands. For more detailed information, refer to the MagTek
Device Driver for Windows, Programming Reference Manual (P/N 99875125).
The drivers may also be downloaded from the Internet at www.magtek.com Software/Device
Drivers.

SWB PARAMETERS
The SWB functions are listed in Table 4-2 and described below.
Control Characters and MICR Data
Control Characters may be added to the MICR data message. The characters are always in the
following locations:
<STX> <ESC> data <ETX> <CR> <LF>
The control characters, descriptions, and hex values are shown in Table 4-3.
Table 4-3. Control Characters
CONTROL

<STX> Start of Text 02
<ESC> Escape 1B
<ETX> End of Text 03
<CR> Carriage Return 0D
<LF> Line Feed 0A
DESCRIPTION
HEX VALUE
For example, if <STX> and <CR> are set to YES, the message from the MICR Reader will look
like this:
MICR Data: <STX>data<CR>
Control Characters and Card Data
The control characters are also available for card data but they are applied to each track
individually. For example, if the <STX> and <ETX> options are set to YES, the card data
message is transmitted as follows:
The selection of comm modes is a quick way of selecting multiple Control Characters. For
instance, to send a carriage return/line feed pair after the data, you can specify Comm Mode 3.
Comm Mode 7, also known as Packet Mode, calculates an LRC (Longitudinal Redundancy
Check), and appends it to the data message. Also, if a <NAK> (hex 15) character is received in
this mode, the MICR Reader will resend the last message.
10
Section 4. Commands
Send Data After Error
The request Send Data After Error specifies whether the MICR Reader will return data to the Host
after a read error. If YES is selected and the MICR Reader detects a read error, the MICR Reader
will still send the data back to the Host. If NO is selected and the MICR Reader finds an error, it
will discard the data and nothing will be sent. The error conditions are listed in Table 4-4.
Send Status After Data
The Send Status After Data option makes the MICR Reader append a two-digit error/status code
to the end of the MICR data. For most formats (See Appendix A), the error/status code will
always be preceded by a forward slash (/). The error/status codes are listed in Table 4-4.
For example, if a Canadian check (code 08) is read and had no errors, and the MICR data is
“1234567890”, then the message from the MICR Reader will look like this:
MICR Data: 1234567890/08
The status code is always at the end of the data, not the end of the message. For example, using
the above conditions, with the message format set to send <STX> and <ETX>, the message from
the MICR Reader will look like this:
MICR Data: <STX>1234567890/08<ETX>
Table 4-4. Error and Status Codes
PRIORITY CODE TYPE DESCRIPTION
9 01 Error No MICR data: no transit and no account found
8 09 Status Mexican check
7 08 Status Canadian check
6 05 Error Transit error: No transit, bad character, bad
length, bad check digit
5 07 Error Account error: No account, bad character
4 04 Error Check # error: Bad character in check number
4 04 Status No check number
3 03 Status Low MICR signal, good read
2 10 Status Business check
1 11 Status Amount field present
0 00 Status Good read
Notes:
• The LED indicator will turn red on all error conditions.
• The absence of a check number is not considered and error.
• If a multiple error condition occurs, the error or status code with the highest priority is reported.
• All unreadable MICR characters are transmitted as an “?” ASCII character (hex 3F), except for
Format 00xx (See Appendix A).

MINI MICR USB with 3-Track MSR
SWC - SWITCH C COMMAND
The SWC command controls miscellaneous functions, shown in Table 4-5. The data for this
command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
To execute, send the SWC command as follows:
SWC 01010101<CR> (with data)
or
SWC <CR> (without data)
When sending data, all 8 bits must be provided. The MICR Reader will execute the command but
it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA (Save) command described at the end of this section.
If no data is sent, the MICR Reader responds with the current settings for SWC.

12
Section 4. Commands
SWC PARAMETERS
The SWC functions are listed in Table 4-5 and described below.
CMC-7 Character Set
If NO is selected the MICR Reader will only read E13-B characters. When YES is selected, the
MICR Reader will read both CMC-7 and E13-B characters (see Appendix B). However, the
MICR Reader will only output raw data ("as is" on the check) for checks with CMC-7 characters.
Invalid Command Response
Invalid command response is the action the MICR Reader takes upon receipt of a command it
does not recognize. It can also be used to stop the MICR Reader from receiving any more
commands.
The first option “?<CR>” is the default. If the MICR Reader receives an unrecognized
command, it will return a question mark and carriage return to the Host. The MICR Reader will
then return to an idle state and wait for further commands or check/credit card reads.
For the second option, “no reply - header required,” the MICR Reader will only execute
commands preceded by a GS ASCII character (hex 1D). All other commands will be ignored.
Also, the MICR Reader will not reply to invalid commands.
For the third option, “no reply,” the MICR Reader will execute all valid commands, but it will not
reply to invalid commands.
The fourth option, “ignore all commands,” causes the MICR Reader to ignore any further
commands. Even the SA (Save) command is ignored and therefore this fourth option is only
temporary. To make this option permanent or to reset it, you must use an Insta-Change check.
13
MINI MICR USB with 3-Track MSR
Data Header
If YES is selected, a single character header precedes the data. For MICR data, the message is
transmitted as follows:
MICR data: ‘C’[data]
For card data, the header position on the message is controlled by the Card Data Message
parameter (see below). Therefore, the message may be transmitted as follows:
If Multiple Message: ‘M’[TK1]‘M’[TK2]’M’[TK3]
If Single Message: ‘M’[TK1] [TK2] [TK3]
It is important to note that the Data Header precedes the data and not the message. For example, if
<STX>, <ETX> and Data Header are set to YES, a MICR data message will be transmitted as
follows:
MICR data: <STX>‘C’[data]<ETX>
Card Data Message
This option determines the structure of the output message for the individual tracks when a credit
card is read. If Multiple is selected, the Control Characters (see SWB, below) and Data Header
(see Data Header, above) are added to each track individually. On the other hand, if Single is
selected, all available tracks are lumped together into a single message. For example, if <STX>,
<ETX> and Data Header are set to YES, the output message may be transmitted as follows:
If Multiple Message: <STX>‘M’[TK1]<ETX><STX>‘M’[TK2]<ETX><STX>‘M’[TK3]<ETX>
If Single Message: <STX>‘M’[TK1] [TK2] [TK3]<ETX>
14
Section 4. Commands
HW - HARDWARE COMMAND
This command controls miscellaneous hardware options, shown in Table 4-6. The data for this
command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
To execute, send the HW command as follows:
HW 01010101<CR> (with data)
or
HW <CR> (without data)
When sending data, all 8 bits must be provided. The MICR Reader will execute the command but
it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA (Save) command described at the end of this section.
If no data is sent, the MICR Reader responds with the current settings for HW.
Each Track can be enabled or disabled individually. The tracks are always transmitted in
ascending order: TK1, TK2, TK3. For example, if TK1 and TK3 are enabled and TK2 is disabled,
the MSR will transmit TK1, TK3.
ID Card Decoding
The MSR has two modes of operation. In the first mode, ID Card decoding disabled, the MSR will
only read ISO encoded cards. In the second mode, ID Card decoding enabled, the MSR will read
and autodiscriminate ISO, AAMVA, and CDL encoded cards. When a card is swiped, the LED
indicator will turn red and indicate an error if any of the enabled tracks read is incompatible with
the selected mode of operation. TK2 is a standard track for all types of cards.
EMF Detect
The EMF Detect option allows the MICR Reader, when idle, to monitor EMF interference in its
immediate environment. If YES is selected, the LED indicator will blink red/green when the
MICR Reader detects a signal with amplitude large enough to affect check reading. If NO is
selected, the MICR Reader will not monitor nor indicate the presence of EMF interference.
FC - FORMAT CHANGE COMMAND
Formats are used by the MICR Reader to process and transmit the MICR fields. The format
command allows the selection of a format from the Format List, Appendix A. The data for this
command consists of 4 digits (ASCII characters 0-9). To execute, send the command as follows:
FC 6600<CR> (with data)
or
FC <CR> (without data)
When sending data, all 4 digits must be provided. The MICR Reader will execute the command
but it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA (Save) command described below.
If no data is provided, the MICR Reader will respond with the current format number.

Section 4. Commands
VR - VERSION COMMAND
The Version command gives the current software revision in the MICR Reader. To execute, send
the VR command followed by a carriage return as follows:
VR<CR>
The MICR Reader responds as follows:
MICR data: [software revision]<CR>
LE - LED COMMAND
To control the LED, the LE command is sent with a hexadecimal digit (use ASCII characters for
the hex digit):
LE X<Enter>
Where X = Hex digit 0-F.
An example of the “Blink Red” command is:
LE 9<Enter>
The codes and descriptions are shown in Table 4-7. The LE command will control the LED for three
seconds and then return it to the normal state. The description column is a common expression of the
state of the LED.

APPENDIX A. FORMAT LIST
For check reading, the MICR Reader provides the flexibility to format the MICR fields and build a
specific output string that will be transmitted to the Host. These output strings are referred to as formats.
The Reader has a built-in list of formats (described below) from which the user may select one to become
the active format every time a check is read. The formats may be selected using the FC command (Section
4, Commands) or Insta-Change checks provided by MagTek.
Each format is assigned a 4-digit number. The first two digits indicate the format number, and the last two
digits are specific parameters used for various functions by each format. For example, in format “0415”,
the “04” refers to format number 4 and the 15 refers the maximum number of characters allowed for the
account field.
Note
The formats listed in this section apply only to U.S. and Canadian checks.
The MICR line on checks from other countries will not be broken or parsed
as described in these formats.
A complete description for each format follows.
Fmt 00xx:
Xx - specify what symbol set to use. Choose from the table
Add xx + 16 - change multiple spaces to one space
Add xx + 32 - Remove all spaces
• [acct #]: - maximum of xx characters; when xx=00 all characters are sent
- remove dashes and spaces
• [check #]: - all characters in the field- remove dashes and spaces
• [raw data]: - translate MICR symbols to t,o,a,d

Fmt 7700: The Flexible Format
Select this format to activate a preloaded Flexible Format. The Flexible
Format is a feature that allows the user to create custom MICR formats. The
Flexible formats can be easily created and downloaded using the Windows based
MICRbase program provided by MagTek (P/N 22000021). For more detailed
information refer to Section 7 in the MICRbase reference manual (P/N
99875102).

APPENDIX B. CHECK READING
The characters printed on the bottom line of commercial and personal checks are special. They
are printed with magnetic ink to meet specific standards . These characters can be read by a
MICR Reader at higher speeds and with more accuracy than manual data entry. Two MICR
character sets are used world wide; they are: E13-B and CMC-7. The E13-B set is used in the
US, Canada, Australia, United Kingdom, Japan, India, Mexico, Venezuela, Colombia, and the
Far East. The CMC-7 set is used in France, Spain, other Mediterranean countries, and most
South American countries.
E13-B CHARACTER SET
The MICR font character set E13-B includes digits 0 through 9 and four symbols. The numbers
found on U.S. checks are of the E13-B character set. The numbers and symbols of E13-B are as
follows:
Transit symbol
CMC-7 CHARACTER SET
The numbers and symbols of the CMC-7 character set are as follows:
SI SIISIIISIVSV
Dash Symbol
On-Us Symbol
Amount Symbol
