LBT Channel
Sets the default transmit channel of the available ETSI 302-208
channels. When you enable LBT scanning, the channel scan sequence
starts with this LBT channel. When LBT scanning is disabled, (as in
the 4 channel mode) the LBT channel is the only channel used. The
range for 10 channel mode is 4 to 13.
The default for 10 channel mode is 8, and for 4 channel mode the
default is 7.
The valid values in 4 channel mode are 4, 7, 10, 13.
This setting is equivalent to the LBTCHANNEL BRI attribute.
LBT Scan Enable
LBT scanning is enabled, by default in ETSI 10 Channel mode in
accordance with 302-208.
When LBT scanning is enabled, the algorithm scans the available
ETSI 302-208 channels for a free transmit channel.
In continuous read mode, the scan sequence begins with the channel
specified by LBTCHANNEL and every third channel is checked (for
example, 8, 11, 4, 7, 10, 13, 6, 9, 12, 5) until a free channel is found. If a
free channel is not found, LBT repeats the scan sequence.
In single-shot read mode, LBT scanning goes through all available
channels at once. If no free channel is found, the reader will report
“NOTAG” and abort the inventory operation.
When LBT scanning is disabled, the IF30 does not scan for a free
transmit channel, and the transmit channel is set by the
LBTCHANNEL BRI attribute.
This setting is equivalent to the LBTSCANENABLE BRI attribute.
Field Separator
Sets the space character to be used for separating fields in tag data.
Choose either space ( ) or comma (,). Default is space.
This setting is equivalent to the FIELDSEP BRI attribute.
Note: LBT scanning is permanently disabled in ETSI 4 channel mode
in accordance with 302-208 v1.2.1.
