Data format (OMRON Isgus)
Each message below consists of a sequence of letters ("characters").
Each "character" is represented by a sequence of 5 bits (BCD code +
parity):
Bit 1 (LSB) Bit 2
Data structure of a message:
S BBBB M AAAA E L
Meaning:
S
B
M
A
E
L
A reduced reader range is required in some situations. The near-field option
reduces the reader range for transponders. This reduces the influence of
possible interferences and prevents the transponder from overriding.
