–
Template
: Selection of a predefined frequency channel list
–
Start freq
: Start frequency in MHz when using the custom template
–
End freq
: End frequency in MHz when using the custom template
–
Increment
: Frequency increment in MHz when using the custom template
–
Randomize
: If activated, the frequencies in the channel list are randomized when
“Create new List” or “Load from file” is selected
–
Append
: If activated new frequencies are appended to the current channel list. If
deactivated, the new frequencies overwrite the current channel list.
–
Create new List
: Creates a frequency channel list depending on the parameter:
“Template”, “Start Frequency”, “End Frequency” or “Increment”.
–
Load from file
: Load frequency channel list from file
–
Clear list
: Clear current list
–
Save to file
: Save current list to file
Note:
The frequency channel list is applied only when “OK” is pressed.

Frequency hopping panel
•
Hop mode
: Selection of frequency hopping modes:
–
Wait
: Transmit on the current frequency channel until the maximum sending time
has expired.
–
Power Save
: Stop transmission if the inventory round no longer produces TAGs,
or if the user minimum sending value expires. The frequency hop happens after
the maximum sending time has expired.
Note:
This hopping mode can be used for ETSI and FCC frequencies.
–
Fast
: Perform an immediate frequency hopping if the inventory round does not
produce additional TAGs, or if the user defined min/max send time values expire.
–
Fast FCC
: Perform immediate frequency hop if inventory round no longer
produces TAGs, or if the user defined min/max send values expire. The
implementation takes care that within an interval of 20 sec each frequency
channel is used 400 ms for transmission.
•
Minimum sending time
: Minimum transmission time on a frequency channel. If no
TAG is detected for the duration of the minimum sending time, a new frequency
channel is selected.
•
Maximum sending time
: Maximum transmit time on a frequency channel. When the
maximum sending time is expired the reader hops to the next frequency channel. The
maximum sending time value must follow local radio regulation requirements.
