For Testing Purposes PEARL62 is used:

The Programming will begin, wait until “Re-booting to Application Code” is displayed before you begin testing

Using Monex seet up the level transmit controls as shown below:

The received Level value should be 57.08% (red bar on the right of Monex)

The top left and top middle LED's should be flashing green every 2.5 seconds, and the blue LED should also be flashing every 2.5 seconds.

Change the level values to the ones shown below:

The received Level value should be 51.29% (red bar on the right of Monex)

Go to the Device Info tab and change the Hex switch value on the PCB, monitor Device Inst Upper/Lower to make sure it matches the switch value.

Use a RPT112 box and a 200374 insert
