Important! - Read and follow the instructions below even if you are not using this kit with an AAG anemometer.
Refer to the layout diagram for clarification of parts placement. All references to up, down, left, and right assume that you are looking at the PCB with the silkscreen TAPR logo oriented up on the board. Unless noted otherwise, all components are mounted on the top of the PC board.
The external 5V jumper, located at P1, determines which lines are used to supply 5V to the X1W-2 and AAG 1-Wire anemomoeter. When AAG released "Version 3.0" they changed the lead in the 1-Wire cable that carries the 5V supply. The wire they switched to will cause a direct short to ground for the supply line if using previous versions of the T-238, X1W-2 (original release) and the betas of the X1W-1 and X1W-2 (rev 2). The addition of another position for P1 solves this problem.
If you have "Version 3.0" of the anemometer, then P and 2 should be jumped. If you have an older model or you are not using the AAG 1-Wire anemometer, then jump P and 1.
Install a push-on shunt in the position as determined above at P1.
|P to 2 if AAG Ver 3.0 attached|
|P to 1 if earlier or no AAG attached|
Testing with the anemometer assembly connected will take place during the testing phase later.
