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

SECTION 1. OVERVIEW

The MINI MICR WEDGE 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 connect between the PC and the keyboard using the split wedge interface cable. The original connection between the PC and the keyboard is maintained. The MICR Reader will transmit all data as scan codes and the PC will receive it as if it was entered using the keyboard.

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.

• Ability to create custom formats to transmit MICR data, plus an extensive list of built-in

formats.

• Optional error/status reporting for check reading.

• Reads E13-B and CMC-7 MICR fonts.

• EMF noise detection

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

3. On the interface cable, connect the 9-pin male DIN connector to the MICR Reader.

MINI MICR WEDGE with 3-Track MSR

4. On the interface cable, connect female DIN connector to the keyboard cable. Pin lists

and connector illustrations are shown in Appendix E.

5. On the interface cable, connect the male DIN connector to the PC.

6. On the AC power adapter, connect the jack to the plug on the MICR Reader.

7. On the AC power adapter, connect the plug to the wall outlet.

8. Power the PC on. 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 MICR 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 (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.

The following methods are available to execute MICR commands:

• Insta-change checks

• MICRbase setup program for Windows

• MagTek Device Drivers for Windows

• User application without drivers

INSTA-CHANGE CHECKS

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 under Software/Demo Programs.

MINI MICR WEDGE with 3-Track MSR

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.

USER APPLICATIONS WITHOUT MAGTEK DEVICE DRIVERS

For applications that communicate directly with the MICR Reader, the following programming procedures must be considered:

PC Commands To Enable and Disable Keyboard Wedge

Because the system is connected from the PC to the MICR Reader to the PC keyboard, the user must cut the communication between the MICR Reader and the keyboard. This is accomplished by sending a Disable Keyboard (DK) command. This command permits the PC to send commands to the MICR Reader. After the commands have been sent to the MICR Reader, the PC must send an Enable Keyboard (EK) command to reestablish communication between the PC and the keyboard.

PC Timing

The timing between each character sent to the MICR Reader must be in the range of 5 milliseconds to 150 milliseconds.

The timing between the last key pressed (from the keyboard) and the first character of the MICR Reader command should be 500 milliseconds.

Keyboard Wedge Port IO Addresses

For the PC program, the keyboard port IO address is 60 HEX for AT and PS/2 model 50. The address for all other PS/2 models is 68 HEX.

Section 4. Commands

COMMAND FORMAT

When the commands are entered manually, they must use the following format:

[COMMAND][DATA] <ENTER>

• [COMMAND] is 2 or 3 alpha characters.

• [Data] is optional as described below for each command.

• <ENTER> is always required.

• All characters are ASCII

• No spaces, brackets, or angle brackets required.

DK – DISABLE KEYBOARD

When a PC program is used, the keyboard must be disabled to allow programming of the MICR Reader. Commands used for programming the MICR Reader are described below. The command to disable the keyboard is:

DK <ENTER>

The MICR Reader will execute the command and will reply with lower case 'k'.

EK – ENABLE KEYBOARD

After all commands have been sent to the MICR Reader, communication between the PC and the

keyboard must be established. The command to enable the keyboard is:

EK <ENTER>

The MICR Reader will execute the command and will reply with lower case 'k'.

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).

To execute, send the SWA command as follows:

SWA 01010101<ENTER> (with data) or SWA <ENTER> (without data)

MINI MICR WEDGE with 3-Track MSR

When sending data, all 8 bits must be provided. The MICR Reader will execute the command but it will not reply. The SWA options are saved immediately.

If no data is sent, the MICR Reader responds with the current settings for SWA.
