UID Output Pattern Configure
Command to configure: E0 00 00 40 02 AB XX
Parameter Detail:
A – Read Mode Configure
= 1xxxb -> Reserved
= 00x0b -> No CapsLock before and after output
= 00x1b -> CapsLock before and after output
= 000xb -> Only Support 4 bytes UID
= 001xb -> Support 4, 7, 10 bytes UID
B – Output Format
= 0000b -> Hex Bytes
= 0001b -> Dec Bytes
= 0010b -> Dec Word
XX – Output Format
= 00h -> ascending order (UID Byte 0, UID Byte 1 … UID Byte N)
= 01h -> descending order (UID Byte N, UID Byte N-1 … UID Byte 0)
Character insert between each UID bytes and after the output Configure
Command to configure: E0 00 00 41 02 YY ZZ
Parameter Detail:
YY - the character between each UID
= FFh mean no character between or
= other character table refer to "HID Usage Table.pdf" p53 - p59
ZZ - the character end of output
= FFh mean no character follow or
= character table refer to "HID Usage Table.pdf"
Example
Example 1:
Set the output as Hex Bytes, support 4,7,10 bytes UID, with no CapsLock before, ascending order
"Spacing" between UID, "Enter" later all the UID
A = 0010b
B = 0000b
XX = 00h
