Description of the configuration parameters of the RRU4 reader system
2.1.
The “Global” configuration group
2.1.1.
“DefaultParamset”
Characteristics:
available from firmware:
v1.30.00
Data type:
Byte (8-bit)
Unit:
–
Value range:
0-7
Description:
This parameter is the only one in its configuration group. In contrast to all the other parameters, this one is
“independent”. That means that this parameter is not held in any parameter set, it just exists on its own. The parameter
indicates which parameter set is loaded and activated when the reader is started up.
2.2.
The configuration group “RFInterface”
2.2.1.
“RFPower1...8”
Characteristics:
available from firmware:
v1.30.00
Data type:
Byte (8-bit)
Unit:
¼
dBm(erp)
Value range:
0; 68-136
Description:
This parameter allows the reader transmission power to be set for respective antenna port. More precisely: The
power which the antenna should radiate. The data is given in
dBm(erp)
. So that the power radiated by the antenna
really does correspond to the value of this parameter, the parameters for the attenuation of the antenna cable
and the antenna gain must be set correctly.
It is a precondition that the transmission power is set to a value greater than 0
dBm(erp)
, in order that an inventory
can be performed using this antenna port.
Note
The transmission power is always set in dBm(erp). If the desired transmission power is stated in dBm(eirp),
this must be converted to dBm(erp):
dBm(erp) = dBm(eirp) - 2.14
