Jumper Installation
1-Wire Indoor Sensor/Interface Kit

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.


Push-On Shunts

Install a push-on shunt in the following positions. Additional shunts will be installed later during the testing phase.

Ok
Procedure
  Vad to Cal at P14
  In to Sensor at P13

Wire Jumpers

Stop! If you are using the board with the RM-60 or RM-70 radiation monitor, proceed to the RM-60 installation page and complete Section 3: Jumpers. Otherwise, continue here.

As with the ferrite bead installation, use clipped resistor leads for jumpers. Form a narrow “U” with the clipped lead and pass the two ends through the PC board. Pull the leads down snug and spread them slightly. The jumper doesn't have to lie flat - just snug.

Ok
Procedure
  Jump Vin to +12 at P19
  Jump A to RG at P1
  Solder and clip four leads. Wear safety glasses and observe proper precautions!

Rain Gauge Jumpers

At this point you will need to determine which of the active pins are connected to the rain gauge reed switch. Both Davis and Rain-Wise gauges parallel two conductors for one signal lead (four conductors total). The following procedure will determine which pins should be used. It is assumed that a RJ11 6-4p plug is on the end of the cable coming from the rain gauge. If not, one will need to be placed on the end of the cable before proceeding.

As before, you may use clipped component leads. If the clearance between the jumper and other pads or components is too close, insulated wire can be used instead. As each jumper is installed, solder and clip the leads.

Ok
Procedure
  Jump one of the selected pins (W, X, Y, or Z) to A at JMP2
  Jump the remaining selected pin (W, X, Y, or Z) to B at JMP2
