NN- a character position in the ID-Code counting from 1 in Hex form (range:
01H-25H), cc- checksum
From Character, together with Number of characters setting allows you to
extract and store into the database a portion of code from the User UD-Card
instead of the entire ID-Card code. This way you can adjust the format of the
data generated by the TR510E to the requirements of some specific PC
software. You can also use this setting to "hide" a certain portion of the ID-
Cards code. This is useful for simple access control function implementation.
From Character defines a character position in the ID-Code (counting from
1), starting from which the portion of an ID-code will be extracted. The valid
range for this setting is from 1 to 37. The TR510E will reject any User Card with
the ID-code with the number of characters in it smaller than current From
Character value.
Example: Supposing that From Character=3 and Number of characters=2.
Then, ID-code "123456" will be truncated to "34", ID-code "123" will become "3",
and ID-code "12" will be rejected.
Default value for this setting is 1.
