Read times from
data carrier to
processor in
static mode
(parametering:
2nd byte, bit 5 = 0)
The indicated times apply after the data carrier has been recognized. If the data carrier is not
yet recognized, an additional 45 ms for building the required energy field until the data carrier is
recognized must be added.
For double read and compare:
Data carrier with 32 byte blocksData carrier with 64 byte blocks

n = number of contiguous bytes to write
y = number of blocks to be processed
Example: 17 bytes from address 187 have to be written. Data carrier with 32 bytes per block.
The blocks 5 and 6 will be processed since the start address 187 is in block 5 and the end
address 203 in block 6.
t = 2 * 120 + 17 * 10 = 410 ms
