Description
Activation/deactivation of the A/B flip function
This function ensures that with every read operation, two read steps are per-
formed. With the first read step, all transponders in status. "A" (default status)
located in the antenna field are identified. With the second read step all tran-
sponders in status "B" located in the antenna field are identified. This increas-
es the probability that all transponders will be identified.
Normally transponders are in status "A". If a transponder is identified, depend-
ing on the set session. it changes briefly to status "B" before it automatically
changes back to status "A". This distinction between these statuses allows
large transponder populations to be identified quickly and reliably.
Specifies the data transfer rate, radio, profile and coding:
Tx: Data transfer rate from reader to transponder
•
Rx: Data transfer rate from transponder to reader
•
Miller/FM0: Coding of the transponder signal
•
Miller is used with the "Dense Reader Mode". The "Dense Reader Mode"
allows the operation of neighboring reader systems on an identical fre-
quency channel. If an FM0 profile is selected, neighboring readers can
have greater influence on each other.
ISO 18000-6B: Changeover of the transponder standard
•
When using transponders of the ISO 18000-6B standard (U code HSL),
this scheme must be used. Note that mixed operation with transponders of
the ISO 18000-6B and ISO 18000-6C standard is not possible.
Off delay of the carrier frequency in seconds. This mechanism can reduce the
time required to access transponders that are accessed more than once in
succession. This time specifies how long the reader remains active after tran-
sponder access. During the off delay time, the reader is quicker when re-
accessing transponders that have already been accessed.
Value range
Increment
Number of inventories to be taken without being interrupted by a send pause
(intermission).

Value range
Increment
Maximum duration of the intermission in milliseconds between the "inventories
without intermission". The length of time of the individual send pauses vary
randomly within the range of values you have specified.
Value range
Increment
Activating/deactivating the cyclic antenna test.
If the cyclic antenna test is active, the reader checks whether or not the anten-
nas are plugged in and connected to the reader. To do this, the antennas are
accessed with minimum power. To make sure that antennas radiate power
only when this is specifically required, you can disable the antenna test.
Without the cyclic antenna test, an interrupted connection can only be detect-
ed when the antenna is accessed.
