Figure 1-1. MICR Plus
SECTION 1. OVERVIEW
The MICR Plus is both a MICR (Magnetic Ink Character Recognition) Check Reader and an
MSR (Magnetic Stripe Reader).
The MICR Plus, 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 Plus improves accuracy and speed because there is no manual data entry;
therefore there are no keying errors or unwanted delays.
The MICR Plus will communicate with the Host system using a standard RS-232 interface. All
data is transmitted as ASCII characters (See Appendix G). The MICR Plus has the capability of
supporting some hardware handshaking signals. (See Section 4, Commands.)
The MICR Plus also has an auxiliary RS-232 port for connection to another RS-232 device, such
as a PINPad or bar code reader.
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 or CMC-7 MICR fonts.

MICR PLUS, RS-232
The ports are for the following connections:
• The RS-232 Host port is used when connecting to an RS-232 Host.
• The ECR port is used when connecting to an ECR Host.
• The RS-232 Auxiliary Port is used to attach an external RS-232 device to the MICR Plus.
The MICR Plus in turn, acts as a communication bridge between the external device and the
Host device.
• The Power plug connects to an adapter and wall power.
To Install the MICR Plus, perform the following steps:
1. On the interface cable connect the DB25/DB9 connector to the PC. The pin lists for
these connectors are shown in Appendix F.
2. On the interface cable connect the 8-pin RJ plug to the RS-232 Host port.
3. If an external RS-232 device is to be used, connect the cable from the RS-232 device to
the RS-232 auxiliary port. An example is shown in Figure 2-2.
Note
The RS-232 auxiliary port will be set with the same communication
parameters as the RS-232 Host Port.

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 Plus 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 unit 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 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 Magnetic Stripe Reader (MSR) in either direction, but the
magnetic stripe must be oriented in only one direction as shown in Figure 1-1. The reader 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 command (Section 4, Commands).

SECTION 4. COMMANDS
This section describes the use of commands and programmable options available for the MICR Plus.
Note
All options described below can be factory set as specified by the user
when ordering.
To execute the MICR Plus commands, either one of two methods is required: Insta-Change Checks or a
PC with a program that provides access to a serial communications (COMM) port.
INSTA-CHANGE CHECKS
The first method is the use of Insta-Change checks, which is a more practical way of setting up
the MICR Plus for most applications. The Insta-Change check is an E13-B MICR encoded
document that contains commands and options used to reset the parameters of the MICR Plus.
Multiple commands and options may be contained on one Insta-Change check. When used, the
Insta-Change checks are run through the MICR Plus 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 Plus as described in Section 2, and watch the LED indicator. When the Insta-Change
check is run through the MICR Plus 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.
PC PROGRAM
The second method, the PC program, may be MagTek’s SET-MICR Demo program (Rev P or
higher), or any other PC program that provides access to the COMM port. With the SET-MICR
program, commands may be selected from menus, but with any other program the command data
is entered manually (typed) into the system. Whether SET-MICR, or any other program is used,
the PC and the MICR Plus must be set to the same communication parameters (baud rate, parity,
stop bits, etc.)
COMMAND FORMAT
When the commands are entered manually, they must use the following format:
[COMMAND][DATA]<CR>
Where:
9
MICR PLUS, RS-232
• [COMMAND] is 2 or 3 alpha characters.
• [Data] is optional as described below for each command.
• <CR> is always required.
• All characters are ASCII
• No spaces, brackets, or angle brackets required.
SWA - SWITCH A COMMAND
The SWA command, shown in Table 4-1, controls the communication parameters for the RS-232
Host port. The data for this command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
Note
The RS-232 auxiliary port will be set with the same communication
parameters as the RS-232 Host Port.
To execute, send the SWA command as follows:
SWA 01010101<CR> (with data)
or
SWA <CR> (without data)
When sending data, all 8 bits must be provided. The MICR Plus will execute the command but
it will not reply. To make this command permanent, use the SA command described below.
If no data is sent, the MICR Plus responds with the current settings for SWA.
Note
The new settings for the serial port will not become
The SWA functions are listed in Table 4-1 and described below.
Baud Rate
The baud rate is one of seven speeds at which the MICR Plus communicates with the host. The
lowest speed is 300 baud, and the highest is 19200.
Data, Stop Bits, and Parity
Data refers to the number of data bits used to transmit every character; the options available are
7 or 8. Stop Bits refer to the number of bits used to indicate the end of transmission for every
character; the options available are 1 or 2. Parity refers to a means of detecting bit-level
transmission errors for every character; the options available are None, Even or Odd.
11
MICR PLUS, RS-232
CTS/DSR
When CTS/DSR (Clear to Send/Data Set Ready) is set to Ignore, the MICR Plus sends data to
the host without waiting for the CTS and DSR signals to be active. When CTS/DTS is set to
Use, the MICR Plus waits for the CTS and DSR signals to be active before sending data.
Intercharacter Delay
The intercharacter delay is used to increase the time between characters transmitted from the
MICR Plus. The delay is equivalent to the transmission of one character. This parameter affects
character rate but not baud rate (i.e., each character takes the same time to transmit but the time
between characters is increased).
SWB - SWITCH B COMMAND
The SWB command controls the message format, shown in Table 4-2. The data for this
command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
To execute, send the SWB command as follows:
SWB 01010101<CR> (with data)
or
SWB <CR> (without data)
When sending data, all 8 bits must be provided. The MICR Plus will execute the command but
it will not reply. The new settings become effective immediately.
If no data is sent, the MICR Plus responds with the current settings for SWB. To make this
command permanent, use the SA command described below.

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.
13
MICR PLUS, RS-232
Table 4-3. Control Characters
CONTROL
CHARACTER
<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 Plus will look
like this:
MICR Data: <STX>data<CR>
Control Characters and Card Data
The control characters are also available for card data but their position on the message is
controlled by the Card Data Message parameter (see SWC Command, below). For example, if
the <STX> and <ETX> options are set to YES, the message may be transmitted as follows:
If Multiple Message: <STX>[TK1]<ETX><STX>[TK2]<ETX><STX>[TK3]<ETX>
If Single Message: <STX>[TK1] [TK2] [TK3]<ETX>
Communication Modes
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 Plus will resend the last message.
Send Data After Error
The request Send Data After Error specifies whether the MICR Plus will return data to the host
after a read error. If YES is selected and the MICR Plus reads a check with an error, the MICR
Plus will send the data back to the host. If NO is selected and the MICR Plus finds an error, it
will discard the data and nothing will be sent. The error conditions are listed in Table 4-4.
14
Section 4. Commands
Send Status After Data
The Send Status After Data option makes the MICR Plus 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 Plus 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 Plus 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
6 05 Error No transit, bad character, bad length, bad check digit
5 07 Error No account, bad character
4 04 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 No error, check OK
Notes:
• The LED indicator will turn red on all error conditions.
• The absence of a check number is not considered an error.
• If a multiple error 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).

MICR PLUS, RS-232
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 Plus will execute the command but
it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA command described below.
If no data is sent, the MICR Plus responds with the current settings for SWC.

16
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 Plus takes upon receipt of a command it does
not recognize. It can also be used to stop the MICR Plus from receiving any more commands.
The first option “?<CR>” is the default. If the MICR Plus receives an unrecognized command,
it will return a question mark and carriage return to the host. The MICR Plus 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 Plus will only execute commands
preceded by a GS ASCII character (hex 1D), and it will not reply to invalid commands. When
this option is selected, all messages received without a GS header will be transmitted “as
received” through the RS-232 auxiliary port.
For the third option, “no reply,” the MICR Plus will execute all valid commands, but it will not
reply to invalid commands.
The fourth option, “ignore all commands,” causes the MICR Plus to stop receiving any Host data
and 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.
Active RTS
When this function is set to YES, the MICR Plus will raise RTS and wait 5 seconds for CTS to
become active before sending any data. If the 5 seconds expire and CTS is not active, the data
message will be discarded and nothing will be sent.
17
MICR PLUS, RS-232
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>
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:
18
Section 4. Commands
HW 01010101<CR> (with data)
or
HW <CR> (without data)
When sending data, all 8 bits must be provided. The MICR Plus will execute the command but
it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA command described below.
If no data is sent, the MICR Plus responds with the current settings for HW.
Enable this option when using a Y-cable to connect an additional device on the RS-232 Host
Port. This option allows the MICR Plus and the additional device to receive/transmit data from
the Host.
One important consideration is to determine how the MICR Plus should respond to all data
received from the Host. This response is controlled by the Invalid Command Response. (See
SWC Command, above.)
Disable/Enable Tracks
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 reader will transmit TK1, TK3.
19
MICR PLUS, RS-232
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 indicated 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.
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 Fast” command is:
LE 9<Enter>
LE PARAMETERS
The codes and descriptions are shown in Table 4-7. The color cycle is four equal time periods of
0.1 second. This cycle is repeated for three seconds and then goes off. The description column
is a common expression of the state of the LED.

Section 4. Commands
FC - FORMAT CHANGE COMMAND
Formats are used by the MICR Plus 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 Plus will execute the command but
it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA command described below.
If no data is provided, the MICR Plus will respond with the current setting.
VR - VERSION COMMAND
The Version command gives the current firmware revision in the MICR Plus. To execute, send
the VR command followed by a carriage return as follows:
VR<CR>
The MICR Plus responds as follows:
MICR data: [firmware revision]<CR>
SA - SAVE COMMAND
All changes are considered temporary until the Save command is executed. The Save command
saves all changes to the MICR Plus memory and makes them permanent. The MICR Plus will
execute the command but it will not reply. To execute, send the SA command followed by a
carriage return as follows:
SA<CR>
RS - RESET COMMAND
The Reset command resets the MICR program, and it resets the serial port to the most recent
settings provided by the SWA command. To execute, send the RS command followed by a
carriage return as follows:
RS<CR>

APPENDIX A. FORMAT LIST
For check reading, the MICR Plus 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
MICR Plus 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
• [acct #]: - maximum of N characters (N is on quick-init check)
- remove spaces and dashes
Fmt 73:

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
Dash Symbol
On-Us Symbol
Amount Symbol
CMC-7 CHARACTER SET
The numbers and symbols of the CMC-7 character set are as follows:
SI SIISIIISIVSV

APPENDIX D. RS-232 AUXILIARY PORT
In addition to the RS-232 Host port, the MICR Plus offers the added benefit of an RS-232
auxiliary port. This port allows the user to attach an additional RS-232 device to the Host
through the MICR Plus. For example, Figure D-1 shows Mag-Tek’s IntelliPIN device attached
the RS-232 auxiliary port.

Figure D-1. IntelliPIN on Auxiliary RS-232 Port
In this setup, the MICR Plus serves as a communication bridge between the Host and the RS-232
device, directing the data flow between the Host and the RS-232 device. It should be noted that
at all times, the Host is responsible for the control and operation of the RS-232 device.
COMMUNICATION PARAMETERS
The RS-232 auxiliary port is set to the same communication parameters used by the RS-232 Host
port.
HOST DATA TO AUXILIARY PORT
The MICR Plus will not automatically direct Host data to the auxiliary port. There are two
methods available to direct data to the auxiliary port.
The first method involves bracketing the data with <STX> and <ETX> as follows:
<STX>[Host data]<ETX>
The MICR Plus will automatically remove <STX> and <ETX> from the message, and will
transmit the Host data through the auxiliary port.
53
MICR PLUS, RS-232
The second method requires selecting the “No Reply, Header Required” option for the Invalid
Command Response parameter (See SWC Command, Section 4). When this is selected, any
Host message intended for the MICR Plus must be preceded with a GS (hex 1D) and terminated
with a CR (hex 0D). Any Host message received by the MICR Plus without the GS header will
be transmitted, as received, through the auxiliary port. For example:
Message for MICR Plus: <GS>[Host data]<CR>
Message for Auxiliary port: [Host data]
54
APPENDIX E. DOWNLOADING
The MICR Plus uses flash memory to store all of its firmware. This technical feature allows
firmware changes to be downloaded to the MICR Plus through the RS-232 Host port. The
firmware changes are implemented by MagTek and they are distributed in the form of a special
file called the BIN file (a file with the .BIN extension). This file can then be downloaded to the
MICR Plus with some tools provided by MagTek. The downloading procedure is described
below.
REQUIREMENTS
• Laptop or PC
• MICR Plus, RS-232 interface
• Interface cable, DB25, female, Part Number 22617504 or
Interface cable, DB9, female, part Number 22617506

• Program Mode Insta-Change check for MICR Plus, Part Number 96530022
• Software Utility for Downloading , PROGMICR.EXE, Part Number 22596805
• The BIN file to be downloaded, provided by MagTek
PROCEDURE
1. On the interface cable, connect the DB25/DB9 connector to serial communications port on
the PC. Make a note of the port you are using.
2. On the interface cable, connect the 8-pin RJ connector to the RS-232 Host port.
3. On the AC power adapter, connect the jack to the plug on the MICR Plus.
4. On the AC power adapter, connect the plug to the wall outlet.
5. On the PC, create a directory or folder for the MICR Plus. Copy the PROGMICR.EXE
program and the BIN file to this directory or folder.
6. Read the Program Mode Insta-Change check through the MICR Plus. The LED indicator
will blink red/green fast.
7. On the PC, download the BIN file to the MICR Plus by typing:
PROGMICR xxxxxxxx.BIN (for COMM1)
PROGMICR xxxxxxxx.BIN /2 (for COMM2)
While the BIN file is being downloaded to the MICR Plus, there will be a series of dots on the
screen and the LED indicator will blink red/green slow. When the download is complete, the
LED indicator will be a steady green and there will be a 4-digit CRC number on the screen.
Please make a note of this number for verification.
