Configuration parameters (CFG)
5.2 CFG1: COM interface
Name
Description
COM-
Bus address of the reader (0 .. 254) for communication via the asynchronous interface.
ADR
Notes:
When this parameter is saved on the reader, a plausibility test is run. If an error occurs, the reader replies
•
with STATUS = {0x11}.
The address 255 must not be configured.
•
The reader can be addressed at any time using the COM address 255 in the transmit protocol. It then
•
replies with the set address.
BAUD
Here you set the baud rate of the asynchronous interface.
BAUD
0x05
0x06
0x07
0x08
0x09
0x0A
Notes:
When this parameter is saved on the reader, a plausibility test is run. If an error occurs, the reader replies
•
with STATUS = {0x11}.
A change to the baud rate only takes effect after writing/saving the configuration block CFG1 in the
•
EEPROM and resetting the reader.
If the user sets an invalid baud rate, the reader sets the baud rate to 38,400 Bd.
•
TRANS-
With this byte, you define various parameters of the data transfer format of the asynchronous interface.
