Figure 1-1. MINI MICR USB with 3-Track MSR

SECTION 1. OVERVIEW

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.

• EMF noise detection

• In addition to the USB interface, the MICR Reader is also available with other interfaces.

6. 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.

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).

Check or card read error Good read

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:

The control characters, descriptions, and hex values are shown in Table 4-3.

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 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:

Card Data: <STX>[TK1 data]<ETX><STX>[TK2 data]<ETX><STX>[TK3 data]<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 Reader will resend the last message.
