Low threshold value channel A
Decimal
Default : 0
For a 4-20mA sensor:
• Unit: x 10nA
• Min/Max values: 400 000 to 2 000 000
E.g.: if S326=600 000, the low threshold will have a
value of 600000x10=6 000 000nA i.e. 6mA
For a 0-10V sensor:
• Unit: x 1µV
• Min/Max values: 0 to 10 000 000
E.g.: if S326=1 000 000, the high threshold will have
a value of 1 000 000µV i.e. 1V
S327
4
Value of the low threshold hysteresis of
channel A:
Decimal
Default : 0
For a 4-20mA sensor:
• Units : x 10nA
• Min/Max values: 0 to 1 600 000
E.g.: if S327=200 000, the value of the low threshold
hysteresis will be 200000x10=2 000 000nA i.e.2mA
For a 0-10V sensor:
• Unit: x 1µV
• Min/Max values: 0 to 10 000 000
E.g.: if S327=3 000 000, the value of the low thresh-
old hysteresis will be 3 000 000µV i.e. 3V

3.4.2 Network registers
The list of registers below allows you to change the behavior of the product application. This list is accessible in Provider mode following execu-
tion of the ATT63 Provider command.
These registers must be handled with caution because they could cause problems of communication or of non-compliance with the legislation in
force.

Decimal
Default : 24
Min/max : 0 à 33
Unit : /
See Note 1
S201
Frame format
Decimal
Default : 1
Possibles values:
• 0 : format A
• 1 : format B (minimize frame duration)
• 2 : ‘Universal’ (TX=B, RX=A+B)
S221
AES Mode
Hexadecimal
Default : 0x0000 (no AES)
Possibles values:
• 0x0000 : no AES
• 0x0001 : AES128 with CBC. Using the key defined in registers S222 to S225
Note : encoding the totality of the payload bytes. The encoding is done by bloc
of 16 bytes. If one the bloc is under 16 bytes, the buffer is completed by 0xFF
before AES calculation. In those cases, there are additional bytes.
