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.
