2.
Set the antenna number:
Press PB1 to increase in increment by 1.
Press PB2 to decrease in increments of 1.
Indication: The display alternates between the antenna number and the Tx power level (-8 to
8).
3.
Enable continuous transmission: Press
PB1
and
PB2
simultaneously. Hold them down for 3
seconds. The selected antenna starts transmitting.
Indication: Sound is emitted for 4 seconds. The display shows 'PWR 00X' as shown above
(where '00X' is the current power level)
4.
Hold a passive ID tag in front of the antenna in the location and distance where the ID is
required and use
PB1
and
PB2
to adjust the Tx power level (ID range). Make sure to check the
peripheral range of the ID to avoid overlaps between the stalls.
Indication: The RX LED turns on and sound is emitted (if the buzzer is enabled) while the tag is
within the ID range of the antenna.
Note: The AfiPass II Controller has a built-in safety mechanism that limits the transmission
power, so that it doesn't exceed the permitted power levels. If the power level is too high the
display will show error message 'ERR 06' and the power level must be decreased.
5.
Once the required range has been achieved, press and hold
PB1
and
PB2
simultaneously for 3
seconds to set the power level.
Indication: Sound is emitted for 4 seconds and the display alternates between the antenna
number and the selected power level (as shown in section 2).
6.
Repeat the power level setting process for all the antennas.
