MagTek MAG-WEDGE READER - Manual (Page 7)

SECTION 1. FEATURES AND SPECIFICATIONS
The Mag-Wedge Reader connects in-line between a PC and its keyboard. It is intended to
remain virtually invisible to both the keyboard and the PC until a card is read. When a card is
read, the Mag-Wedge Reader takes over the interface to the PC and sends card data using the
same scan codes used by the keyboard. The PC cannot distinguish between data from the
keyboard and data from the Reader. Mag-Wedge Readers are available for connection to PS/2
and XT/AT type PC's.
The Mag-Wedge Reader also supports the operation of an optional encrypting PINPad that can
be programmed for encrypting or non-encrypting operation. Commands are passed from the PC
to the PINPad, and data from the PINpad to the PC. (XT/AT part numbers 21080005, 21080006
and 21080007 do not support the operation of a PINPad.)
Power is supplied to the Reader by the PC. The Mag-Wedge standard Reader sends card data,
including start sentinel and end sentinel, followed by a carriage return. Units are available which
do not send a carriage return or the start and end sentinel.
The Mag-Wedge Reader also recognizes commands from the PC to enable or disable the
PINPad, the keyboard, or the card reading. When powered up, all devices will be active. The
Reader also initializes the optional PINPad to the non-encrypting mode.
Part numbers and descriptions for the Readers are listed in Table 1-1. Part numbers and
descriptions for models used on older PS/2 Computers are listed in Table 1-2. These models are
available but are not used on modern PS/2 Computers. Configurations other than those in the
two tables are available; call the factory for options.
