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 on the right-hand side of the board. Unless noted otherwise, all components are mounted on the top of the PC board.
|Attach the four 1" 6-32 threaded spacers to the sensor board at the points labeled asp_mt on the pictorial with four 6-32 x ¼" screws. The spacers should be on the top of the PC board (component side). Leave the screws somewhat loose at this point.|
|Place the fan on top of the spacers so that the manufacturer’s label is facing up. There should be an arrow on the side of the unit indicating the direction of air flow. It should point up, away from the sensor board.|
|Attach the fan to the spacers using 6-32 x ¼" round head screws.|
|Snug down all screws, both top and bottom (eight screws total).|
|If a small plug exists at the end of the fan power leads, clip it off as close as possible to the plug. While this may seem to leave more lead than is necessary, it will prove helpful should you need to remove the fan to service the components beneath.|
|Strip 1/8" insulation off both leads and tin the ends.|
|Solder the red lead to J3 pin 1 (square hole) and the black lead to the remaining hole.|
At this point, the power connector and supply leads should be assembled and connected to the board at P1. A female header with contacts is provided for this purpose.
The fan is polarity sensitive and will run on anywhere from about 8V-12V DC. 9VDC wall transformers work well and supply about 12VDC to the fan (most wall transformers normally supply several volts over their rated output).
WXN Server Users
This only applies if you are using N4XI's WXN Weather Server with the X1W-1 inside sensor/control board:
If using the aspirator under programmatic control with the WXN Weather Server, consult the server’s documentation on how to connect the aspirator to the X1W-1’s control output.
Congratulations! You have completed the assembly and initial testing of your 1-Wire® outdoor humidity and temperature sensor. Proceed to the installation.
