Operation
I - Set tuning of the
RF module
Depending on the surroundings of the antenna it might be necessary to tune the
RF module to get the optimal reading/writing range for this special installation
environment. The RF module therefore has 3 capacitors which can be switched
ON or OFF.
Each capacitor has one reserved bit which shows its status.
The tuning can be set manually (not recommended) or automatic tuning can be
performed (recommended).
0 - OFF
1 - ON
Bit 2
0
corresponds to capacitor C
0
.
To start the automatic tuning, use value 08 (I008).
If no reasonable calibration was found, the error "5 - Invalid" is sent instead of
the confirmation, and all capacitors are switched ON.
