Figure 1-1. MINI MICR RS232 with 3-Track MSR
SECTION 1. OVERVIEW
The MINI MICR RS232 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 RS-232 interface.
All data is transmitted as ASCII characters (See Appendix F). The MICR Reader has the
capability of supporting some hardware handshaking signals. (See Section 4, Commands.)
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.
• EMF noise detection
• In addition to the RS-232 interface, the MICR Reader is also available with other interfaces.

• MINI MICR RS232 With Optional 3-Track or 2-Track MSR
• Interface Cable, DB25 female, Part Number 22517507 or
Interface Cable, DB9, female, Part Number 22517509
• AC Power Adapter with Cable, 120VAC to 12 VAC, 1 Amp, Part Number 64300050
PROCEDURE
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 E.
2. On the interface cable connect the 9-pin male DIN connector to the MICR Reader.
3. On the AC power adapter, connect the jack to the plug on the MICR Reader.
4. On the AC power adapter, connect the plug to the wall outlet.
5. The LED indicator on the MICR Reader should turn on to a steady green. The LED
indicator is located below the slot where the check is first inserted for reading.
Caution
Do not place the MICR Reader within 6 inches of a computer
monitor or power supply. These devices may cause undesirable
interference with the check reading operation.

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 Insta-Change checks are run through the MICR Reader the same as a
standard check, and the options to be used are automatically selected. To obtain InstaChange 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 Insta-Change 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
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

MINI MICR RS232 with 3-Track MSR
COMMAND FORMAT
When the commands are entered manually, they must use the following format:
[COMMAND][DATA]<CR>
where:
• [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 controls the communication parameters, shown in Table 4-1. The
data for this command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
Table 4-1. SWA Command

To execute, send the SWA command as follows:
SWA 01010101<CR> (with data)
or
SWA <CR> (without data)
8
Section 4. Commands
When sending data, all 8 bits must be provided. The MICR Reader will execute the
command but it will not reply. 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 SWA.
Note
The new settings for the serial port will not become
effective until the RS (Reset) command is executed.
The Reset command is described at the end of this
section.
SWA PARAMETERS
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 Reader communicates with the
Host. The lowest speed is 300 baud, and the highest is 19200.
Data and Parity
The number of data bits and the parity bit are interrelated. If even, odd, or mark parity is
selected, the MICR Reader will use seven data bits per byte with one parity bit. If a
parity of none is selected, the MICR Reader will use eight data bits per byte.
CTS/DSR
When CTS/DSR (Clear to Send/Data Set Ready) is set to IGNORE, the MICR Reader
sends data to the Host without waiting for the CTS and DSR signals to be active. When
CTS/DSR is set to USE, the MICR Reader waits for the CTS and DSR signals to be
active before sending data.
Number of Stop Bits
The number of stop bits is either 1 or 2. Normally, one stop bit is used for most
applications.
Two stop bits are used to allow extra time for slower Host equipment.
Intercharacter Delay
The intercharacter delay is used to increase the time between characters transmitted from
the MICR Reader. The time is increased to 13 milliseconds. 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 Reader will execute the
command but it will not reply. The new settings become effective immediately. To make
this command permanent, use the command SA (Save) described at the end of this
section.
If no data is sent, the MICR Reader responds with the current settings for SWB.
