RFID EM4095 VS RFID ID-12 ID help!!

well hello, i wish you could help me, i bought one of the Mikroe RFID reader and the ID innovations ID-12 RFID Reader, i used both with the same TAG and when i read the TAG with the Mikroe One, i watch like it's obviously that it's encoding is Manchester type.
then i got the 64 bits:

111111111
11111 ;f
00000 ;0
10001 ;8
00100 ;2
00010 ;1
11011 ;D
10010 ;9
01000 ;4
00000 ;0
01100 ;6
10000 ;8

i know the first 9 bit are set, then it comes 2 nibbles with the fabricant id, later the 32 bits for the card ID, then the row parity bits, then the column parity bits... and bla bla...

well i got this code from the TAG: 0002021288

and when i read it with the ID-12 i got this code I KNOW It's ASCII, and i know about the Check Sum bytes.

i got this:

3F-001ED7A8-5E

and when i convert: 001ED7A8 to decimal i got the TAG 0002021288, then the ID-12 is correct, the em4095 reads in manchester, also de ID-12, but ID-12 converts to serial 9600 bps,1sb,none, i wish to know if someone know's

HOW DID I CAN CONVERT THIS...


111111111
11111 ;f
00000 ;0
10001 ;8
00100 ;2
00010 ;1
11011 ;D
10010 ;9
01000 ;4
00000 ;0
01100 ;6
10000 ;8


INTO THIS!!!
