11.4 Parameter
Since software revision V1.5 some parameters are implemented
for each antenna port (
parameter array).
Addressing of the
parameter takes place via the reader ID of the message. In this
realisation, the parameter is present once per antenna port.
If no parameter arrays should be used, please ask the manufacturer
(parameter 63)!
Since software revision V1.5, the reader is always started with the
default baud rate 19200Bd because of the protocol recognition.
Please ask manufacturer HERMOS if other baud rate is required!
