B.5.0 Interfacing to the Magnetic Card Reader
This section details the software steps required to access the MC reader from a
•
computer or a terminal.
The Host Selects the printer by activating the RTS input line or sending wake-up
•
characters to the printer.
The Printer Sends the XON command to the host to indicate that it is ready to
•
receive data from host.
Once XON is received the host sends ASCII serial command string to enablethe
•
magnetic card reader (e.g. Esc-m004-cr). The printer turns on the GREEN
<READY> LED.
Once the operator swipes the magnetic card, the printer transmits in ASCII format
•
the tracks information found on the magnetic card.
A good read automatically turns off the MC reader and the <READY> LED.
•
The <READY> LED illuminates RED if an error is encountered, while reading the
•
magnetic card.
Printer transmits timeout error message if the operator fails to swipe a card in the
•
time period set by the host application.
