Read times in
static mode
(configuration 3rd byte,
bit 5 = 0, without
CRC_16 data check)
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 recog-
nized must be added.
For double read and compare:
Data carrier with 32 byte blocks Data carrier with 64 byte blocks
No. of bytes Read time [ms] No. of bytes Read time [ms]
from 0 to 31 110 from 0 to 63 220
for each additional
32 bytes add 120
for each additional
64 bytes add 230
from 0 to 255 = 950 from 0 to 2047 = 7350
Including readback and compare:
Data carrier with 32 byte blocks Data carrier with 64 byte blocks
No. of bytes Write time [ms] No. of bytes Write time [ms]
from 0 to 31 110 + n * 10 from 0 to 63 220 + n * 10
for 32 bytes or more y * 120 + n * 10 for 64 bytes or more y * 230 + n * 10
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

CRC_16 data check)
Read times within the 1st block for dual read and compare:
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 recog-
nized must be added.
Formula: t = (m + 1) * 3.5 ms
Example: Read 11 bytes starting at address 9, i.e. the highest address to be read is 19.
This corresponds to 70 ms.
