Error Numbers
The BIS S-810 always outputs an error number. The meaning of these error numbers is indi-
cated in the following table.
Reading / Writing over the serial interface

Read/Write Times

For double read and compare:
Including readback and compare:
n = number of contiguous bytes to write
y = number of blocks to be written
Example:
Read 17 bytes starting at address 187. data carrier with 64 byte blocks. Blocks 2 and 3 have to be ac-
cessed, because start address 187 is in block 2 and end address 203 is in block 3.
t = 2 * 220 + 17 * 10 = 610
The indicated times apply after the data carrier has been recognized. Otherwise an additional 45 ms
must be added to allow for the energy field to be established until the data carrier is recognized.
Times for sending the data over the interface must also be added.
