MUX-VALID-TIME-ANT_x:
(AirInter-
face.Multiplexer.HF.External.Antenna.Nox.ActiveTime)
Immediately this time has expired (value x 5ms), the next antenna output is selected.
If
MUX Switch Condition
is “no response” the Reader switches from the active antenna
to the next antenna if there is no response from any Transponder on the active antenna. If
the Transponder communication time on the active antenna exceed the MUX-VALID-
TIME-ANT_x the Transponder communication on the active antenna is stopped, and the
Reader switches to the next antenna. If „
fixed
“ is selected under Switch Condition, the
switch to the next channel is always made in this time.
INPUT-CHANNELS:
(AirInterface.Multiplexer.HF.External.InputChannelMode)
Specifies the number of inputs
b00: -
b01: 1 input (Single Mode)
b10: 2 inputs (Dual Mode)
> b10: reserved
The multiplexer has two inputs (for receiving RF power from the Reader) and eight out-
puts (which can by connected to the antenna). Each output can be assigned (by jumper in
the MUX Hardware) to one of the two inputs. Only one output per input can be active at a
time. In Single Mode only one channel is enabled, whereas in Dual Mode two channels
are enabled.
