You should see information in both GUI windows indicating the transmission and reception of data.
After the specified number of bytes have been transmitted, you can terminate Tx and Rx scripts.
Please contact CML Technical Support if you have any questions or require further assistance.

The PE0003 GUI allows you to give a name to the PE0003 that will be displayed in the GUI Title Bar.
It may help to name one PE0003
Transmitter
and name the other
Receiver
. Click the Options button
in the GUI to access the Name feature.
If the Tx board is positioned to the left and the Rx board is positioned to the right, arrange the GUI
windows on your desktop in the same manner as a reminder of which GUI controls which board.
Keep a reasonable space between RF evaluation boards to avoid RF coupling issues.
Keep RF leads routed away from the boards and each other when making precise measurements.
This will avoid signal coupling affecting the results.
The PE0003 generates high spurious noise typical of high speed processors and this may be coupled
into the RF circuits. While every care has been taken to avoid issues, optimum performance will be
achieved with a production design that includes overall shielding and consideration of the layout with
respect to the processor speed and proximity.
Do not use antennas as RF energy will couple into unscreened areas and degrade performance.
