9.3 Addressing the antenna port
The reader LFM 4x is equipped with 4 antenna ports. Each of these ports has its own
antenna tuning with which the connected antenna is tuned to the ambient conditions.
In the set protocol, the read or write commands are always executed by port. The 4 antenna
ports from 1 to 4 are numbered consecutively and are addressed accordingly in the logging
command.
In the ASCII protocol, the reader ID decides on the selection of the antenna port.
The reader ID
(„1“ to „4“) responds to the respective antenna port 1 to 4. Depending on the
Factoryparameterset
, it is possible to select the value range of the reader ID from „0“ to „3“ or
from „1“ to „4“.
In the SECS protocol, the target ID is used to select the antenna port: Target ID
„01“ to „04“
responds to the respective antenna port 1 to 4.
For customer-specific solutions, another reader (eg HFS ESN) can be connected to the
RS232 interface. This reader is then used to communicate via the Target ID
„05“ or Reader
ID
„05“.
