For more information, refer to the section "Configuration parameters (CFG) (Page 21)".
Note
Error code 0x15
A read configuration from the EEPROM with reserved configuration blocks causes error
code 0x15.
6.2
[0x81] Write Configuration
With the "Write configuration" command, you change the configuration of the reader. To do
this, you write 14 byte long blocks to the configuration memory. For addressing you use
CFGn in the CFG-ADR byte. You will find a description of the parameters in the section
"Configuration parameters (CFG) (Page 21)".
