9. Configuring Your RC Switch

9.1. General Configuration Procedure
9.2. Restoring the Default Settings
9.3. Enabling Inversion

The RC switch has two user-settable configuration parameters, threshold and inversion, which are described in Section 7. This section and the following sections explain how to set both parameters.

To configure the device, you will need to be able to connect and disconnect the two parts of the learning mode jumper. This will be required at several points by the instructions in the following sections.

Pololu RC Switch with Digital Output, labeled top view.

For the Pololu RC Switch with Digital Output, the learning mode jumper consists of a pair of exposed pads on the component side of the board. To connect the two pads, you can use a wire, screwdriver, or some other conductive tool.

Pololu RC Switch with Small Low-Side MOSFET, top labeled view.

For the Pololu RC Switch with Small Low-Side MOSFET, the learning mode jumper consists of a pair of exposed pads on the component side of the board. An alternate learning mode jumper is available on the other side of the board and is labeled “LRN”; you can use whichever jumper is more convenient. To connect the two pads, you can use a wire, screwdriver, or some other conductive tool.

Pololu RC Switch with Medium Low-Side MOSFET, labeled top view.

For the Pololu RC Switch with Medium Low-Side MOSFET, the learning mode jumper consists of a pair of exposed pads on the component side of the board. An alternate learning mode jumper is available on the other side of the board and is labeled “LRN”; you can use whichever jumper is more convenient. To connect the two pads, you can use a wire, screwdriver, or some other conductive tool.

Connecting a 1×2-pin male header to a blue shorting block makes a tool that can be used to activate the learning mode on the Pololu RC Switch with Relay.

Pololu RC Switch with Relay, labeled top view.

For the Pololu RC Switch with Relay, the learning mode jumper consists of two holes. You could use a wire to connect the two holes, but we recommend inserting a 1×2-pin male header into the included blue shorting block and using that as a tool to connect the two holes. The assembled version of the switch comes with a 1×2-pin male header. If you have the partial kit version, you can break two pins off of the included male header to get a 1×2-pin piece. To make the contact, stick the two exposed pins into the two holes of the learning mode jumper and then tilt the tool towards the side and press on it to ensure a good connection with the inside edge of each hole. It is not sufficient to just rest the tool on the learning mode jumper; you must tilt it and apply some force.

Pololu 4-Channel RC Servo Multiplexer (Assembled), labeled pinout.

For the Pololu 4-Channel RC Servo Multiplexer, the learning mode jumper consists of a pair of exposed pads on the component side of the board. An alternate learning mode jumper is available on the other side of the board and is labeled “LEARN”; you can use whichever jumper is more convenient. To connect the two pads, you can use a wire, screwdriver, or some other conductive tool.
