Operation
Parameter 169
(0xA9)
RF Interface Multiplexing Exposure Time 8
Dwell time on the antenna port, which is defined as the first list entry of the
multiplexing antenna port list (par. RF Interface Multiplexing Antenna Port 8).
The dwell time indicates how long an inventory is performed on an antenna port
(only for polling actions).
Value range: 0 to 65,535 in ms
Default: 100 ms
Parameter 170
(0xAA)
RF Interface Enable RSSI Threshold At Specific Cmds
Activates or deactivates RSSI threshold check for the specific commands URY,
UWZ, UMZ, UBZ, ULZ and UKZ.
Value range: 0; 255
Default: 0xFF (active)
Parameter 171
(0xAB)
RF Interface Flash Write Additional Power
The transponder requires more power for writing than for reading. Therefore it
needs to be closer to the antenna when writing.
If writing errors occur (Write, Lock, Kill,...) the transmission output can be
increased in steps of 1/4 dB with the Interface Flash Write Additional Power
parameter in order to bridge the gap between reading and writing distance.
Value range: 0 - 48
Default: 0x00
Parameter 172
(0xAC)
Tag Comm Force Power Off After EPC Write
When writing the EPC code, the checksum of the transponder is changed.
Therefore the transponder can not take part in the next inventory. Only by
switching the antenna field off and on will the transponder be reactivated and can
take part in the inventory process again. The parameter specifies the time in 1 ms
steps how long the UHF carrier is switched off after an EPC writing.
Value range: 0 - 255 in ms
Default: 0x00
