Hardware: Sensor Wiring
The Developers Kit uses RJ14 (6p4c) connectors for most of the sensors. The Registered Jack (RJ) series connectors install using an inexpensive crimping tool.
Load Cells
- Remove any heat shrink from the load cell cable.
- Cut off the drain wire.
- Spread out the four wires and arrange them in Red, White, Green, Black order.
- Gently flatten the cable with a pair of pliers.
- Evenly trim the wires so they extend approximately 1/4 inch past the jacket.
- Orient the RJ14 connector so the latch tab is up.
- Insert the wires all the way into the RJ14 connector, making sure that the wires are in the right order.
- Inspect the wires and connector. Make sure the outer jacket is past the strain relief and each wire is all the way to the end of the connector.
- Crimp the connector.
