#133059 - here are the actual values
Responding to: ???'s previous message
some readings with a card. data written on card: 016

0000J1@=OI000000000000000000000000000000
where J is start sentinel ( 74-48=26 = 11010 wich is start sentinel ;48='0'),
1 is 0
@ is 1
L is 7

so here are some consecutives readings with the same card:
---2 OK readings---
0000J1@=OI000000000000000000000000000000
0000J1@=OI000000000000000000000000000000
