will always send a “CR” (carriage return) signal to end of each track data for
separation if this item is unchecked.
MSR TRACK 1 LEADING CODE
MSR TRACK 2 LEADING CODE
MSR TRACK 3 LEADING CODE
MSR ENDING CODE
Once the codes for the sentinels of each tracks are defined to be sent to the
system, the leading codes for each start sentinels and the ending code for the common
end sentinel can be selected from a table of displayable characters with ASCII code
from 20h to 7Eh. Clicking on each left/right button selects each code. The default
track 1 leading code is “%”; the default track 2 and track 3 leading code is “;”; the
default ending code is “?”.
TRANSMISSION INTERCHARACTER DELAY
Usually, the processing algorithm and the keyboard data input buffer in an
operating system are arranged in such a way that the system resources are preserved as
much as possible while data input from the USB keyboard port presents no problem.
However, as we know that the amount of data read from one single swipe of MSR can
be very much larger than any possibly fastest keyboard entry in same duration. Some
operating system may be unable to handle such a bunch of data in so short time.
Therefore, a so-called intercharacter delay is introduced to allow the system to digest
the input data. When data read from the MSR is marching to the system, a
programmable time delay is inserted between any two characters. The value to define
this intercharacter delay ranges from 0 to 32. The correspondent delay time ranges
from 2 ms to 66 ms.
SEND LRC
When the check box is ticked, the MSR sends LRC to the host as part of data
for Application Program to double check.
