Frequency Agility
In exceptionally noisy environments or in case of a high concentration of
radio devices, Star system performance may be improved by configuring
Frequency Agility. Frequency Agility parameters change the way the radio
frequencies are used in a Star communication system.
As when changing the System Speed, use the following procedure:
1. Link the PM9501-AR with a BC9xxx Base.
2. With the PM9501-AR, read one of the “Frequency Agility” programming
la
bels below.
3. Place the PM9501-AR into the BC9xxx.
Reader and Base will then be linked and the new frequencies handling will
be
operational.
DEFAULT
Use default fixed channel
Enable frequency hopping
The channel is changed automatically
it is possible to select a fixed channel with a frequency different
from the default; please contact Datalogic Technical Support for
information about this feature.
For the 910 models, the radio range can change depending on the
Frequency Agility parameter value; in particular, at low speed, the
radio range is shorter when a fixed channel is programmed. See
the Radio Range values in
"Radio Features"
on page 316 of
Technical Specifications.
The frequency agility features are not equally supported for all model
speeds. Please refer to the following table:
