5. Protocols for Reader Control
5.1. [0x52] Baud Rate Detection
This protocol serves to determine the actual baud rate of the Reader’s asynchronous interface.
Host → Reader
1 2 3 4 5,6
6 COM-ADR [0x52] 0x00 CRC16
Host ← Reader
1 2 3 4 5,6
6 COM-ADR [0x52] 0x00 CRC16
Note:
• The return protocol will only be sent if the inquiry is executed with the baud rate and actual
parity of the Reader.
5.2. [0x55] Start Flash Loader
This protocol starts the internal Flash Loader in the Reader to perform a firmware update.
Please read the corresponding update description.
Host → Reader
1 2 3 4,5
5 0x00 [0x55] CRC16
Host ← Reader
1 2 3 4 5,6
6 0x00 [0x55] 0x00 CRC16
Note:
• This command is only available if the correct COM-ADR of the Reader is used.
• All COM-addresses except 255 [0xFF] will be accept.
