This setting is equivalent to the ANTTRIES BRI attribute.

Antenna Timeout

Sets the antenna timeout value (in ms) when Timeout Configuration

mode is enabled. Range is 0 to 65534 (default is 50). This setting is

visible only if Timeout Configuration mode has been enabled. For

help, see “Timeout Configuration Mode” in this section.

This setting is equivalent to the ANTTIMEOUT BRI attribute.

Dense Reader Mode

Check this check box to enable dense reader mode, which is only

supported by EPC Class 1 Gen 2 tags. When dense reader mode is

enabled, these tags respond with Miller Sub carrier encoded data

instead of FM0 encoded data.

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.

Note: LBT scanning is permanently disabled in ETSI 4 channel mode

in accordance with 302-208 v1.2.1.
