Operation
F – Parameter
query
The F command is used to query individual parameters of the device. The number
of the parameter is transmitted in "Parameter No.". The response contains the
parameter number and value. The parameter number and the value should be
specified in HEX format: for example, parameter 11  0x0B.
1) If a parameter number is not specified, the reader will provide all reader
parameters. A single response telegram is then sent for each parameter. The
parameter value can be multi-digit (N>=1)!
Example:
>> F02A (request parameter 0x2A)
<< f02A0F
>> F0 (request all parameters)
<< f000A2
<< f001C9
……
<< f07905
