It can also be useful to use the Jumper settings assistant to determine the best jumper
positions. Just click the positions of the jumpers in the Current image to indicate the
current position of the jumpers on the board. Then click the Check button and the
Advised image will show the advised jumper settings for optimal performance.
Figure 49: Tuning assistant example
Be aware of the high antenna voltages! Switch the power supply to the
transceiver board off before tuning. Do not touch the backside of the
transceiver board or the metal tuning jumper pins when the board is
powered, as this might result in you receiving an electrical shock!
Tolerances in the components of the transceiver board make it possible that the actual
antenna jumper settings are different for each transceiver board and therefore the above
image might differ for each transceiver board.
When the Tuning screen is open, detection of tags is disabled. Make
sure to switch to another screen
if you want to test the detection
performance!
