EPC C1G2
A byte whose bits are dedicated to manage Q value and session/target parameters:
•
Bit 7 … bit 4: Q value in fixed Q selection algorithm or starting Q value in
dynamic Q selection algorithm, as defined EPC Class 1 Generation 2 protocol
(0x0=0 … 0xF=15);
•
Bit 3 … bit 2: Session as defined in EPC Class 1 Generation 2 protocol
(00b=S0, 01b=S1, 10b=S2, 11b=S3);
•
Bit 1: Q selection algorithm (0=dynamic, 1=fixed);
•
Bit 0: Target as defined in EPC Class 1 Generation 2 protocol (0=A, 1=B).
RF Maximum
Allocation
Time
The maximum period of consecutive transmission on the same RF channel. 0 stands
for default settings of the selected region. The allowed values are:
•
Decimal 0 … 99 for time in mseconds (0.00 … 0.99 seconds);
•
Decimal 100 … 199 for time in seconds (0 … 99 seconds).
RF Minimum
Pause Time
The minimum time between two consecutive transmission in the same RF channel. 0
stands for default settings of the selected region. The allowed values are:
•
Decimal 0 … 99 for time in mseconds (0.00 … 0.99 seconds);
•
Decimal 100 … 199 for time in seconds (0 … 99 seconds).
