track data will be in the following format:
WD%….?<cr>[;|
@ ]….?<cr>[+|!|#|&]….?<cr>
where:
% = 7-bit Track 1
; = ISO/ABA 5-bit Track 2
@ = 7-bit Track 2
+ = ISO/ABA Track 3
! = CA Driver License Track 3
# = AAMVA Track 3
& = 7-bit Track 3
Any unrecognized command will respond with an error message:
W?<P025>
Note
The MiniWedge monitors the Caps Lock state for the keyboard. If the Caps
Lock is off, it will not send any shift-key scan codes. If the Caps Lock is on,
the MiniWedge sends shift-key scan codes to capitalize all alpha characters.
MAGWEDGE COMPATIBILITY
There are a number of single-byte parameters that uniquely define the operation of the MiniWedge device
when operating in the MagWedge compatibility mode. These parameters are listed in Table 3-3. The
parameters (or properties) are stored in EEPROM and should not be updated unless the value is incorrect
for the operation. It is suggested that the parameter be interrogated prior to writing to a particular address.
If the value is correct, there is no need to write to that address. The parameters and their attributes are
shown in the table below. Only the Start Sentinel Character parameters are used when operating in the
Windows Driver mode.
When a parameter is modified, it may take about 50 milliseconds before the response will be returned.
Other responses will be returned in about 5 ms.
Note
If two or more devices are active at the same time, the PC cannot tell if the
data came from the keyboard or the Reader.
