Default value is 30dBm (1W).
2.2.2 Setting RF Spectrum
Specific frequency and channel usage dictated by regulations of each country
There are two methods to set RF spectrum.
Method 1: Use the default carrier frequency of the reader.
The default carrier frequency can refer to Frequency parameter tablet in Communication
protocol.
Frequency range which the reader supports is
902.5MHz~927.5MHz
. You can set the
reader in
System Default Frequencies
, as illustrate below:
Note the following when you set RF Spectrum:
◆
The start frequency and the end frequency must not exceed the scope of RF spectrum
norm.
◆
Start frequency must be less than or equal end frequency.
◆
Set start frequency and end frequency to the same carrier frequency, the reader will
work under fixed-frequency.
When the parameter setting completes, RF carrier frequency of reader will be randomly
hopping in the scope of limited range.
The default RF spectrum norm is FCC (
902.5MHz~927.5MHz
).
Method 2: Setting the RF spectrum manually.
Users can set RF spectrum via these three parameters: Start Frequency, Frequency
Interval, The number of Frequency points.
2.2.3 Antenna Connection Detector
Function of
Antenna Connection Detector
is: Checking whether the port is connected to
the antenna before the reader work. If not, users will be notified to connect the antenna.
Please open this function before you use it, as illustrated bellow:
Sensitivity of Antenna Connection Detector is setted by users. Sensitivity of Antenna
Connection Detector is the Return Loss of antenna port, the unit is dB. The larger the
value, the impedance matching requirements between antenna and port must be better. To
ordinary antennas, you can set the threshold to 3-6dB. Sensitivity of Ceramic Antenna
and Handset could be more lower.
Note: 1. Reader detects antenna connections by measuring the Return Loss of RF ports.
2. Reader stops tag operation if Return Loss is above the threshold.
