TOR
TOR – Timeout Reading
After a read is triggered by GT, TOR is a time during which ARE i9 continuously tries to read a transponder UID without
the need to be triggered by the host again. This limits bus traffic considerably. Once a successful read is performed,
continuous reading stops immediately regardless of time and the transponder UID is transmitted to the host. If reading
is not successful, a no read (XXXXXXXX) is sent to the host after TOR time has expired.
The chosen parameter for TOR is sent as acknowledgement.

PARAMETER
FUNCTION
0
limits the reading process duration to exactly one reading cycle
1
limits the reading process duration to maximum 1 times 100ms
2
limits the reading process duration to maximum 2 times 100ms
...
255
limits the reading process duration to maximum 255 times 100ms
A TOR value of 50 equals 50 x 100ms = 5000ms = 5 sec.
It is recommended to set TOR value to the amount of time it takes in a dynamic situation for the transponder to travel over
ARE i9. This maximizes the number of possible reads, in order to compensate for EMV noise in the vicinity.
