Data Sheet

3. Now the device is in the pulse-measuring phase of learning mode. This is where you can

choose what threshold to use.

◦ If you want to use the default threshold, you should not send RC pulses to the

device. The device will indicate that the RC input signal is not recognized by blinking

the LED with a 50% duty cycle and a period of 0.5 s.

◦ If you want to use a custom threshold, you should send RC pulses to the device. The

device will indicate that it recognizes the RC input signal by blinking the LED with

a special pattern that consists of a fade in followed by a blink, with a period of 2 s.

The device will calculate the minimum and maximum pulse widths seen during this

phase of learning mode, and set the threshold equal to the point midway between

them (the average). In general, we recommend moving your input to both the off

position and the on position during this phase of learning mode, and not moving it

anywhere outside of that range. However, if you are using a servo controller to send

pulses, you might want to simply send pulses equal to the desired threshold. If you

accidentally send incorrect pulses, you will have to power off the device and start

over at step 1.

4. Tap the learning mode jumper again to save the chosen threshold. If the threshold you chose

was not within the allowed range of 900 to 2100 μs, then the device will indicate an error by

blinking the LED rapidly eight times per second. If that error happens, the threshold will not

be saved and you should power off the device and try the procedure again with a different

threshold. If the threshold you chose was within the allowed range, then it will be saved to

non-volatile memory and you will see the LED fade in repeatedly with a period of 1 s.

5. You can now chose whether to enable inversion. If you do not want to enable inversion,

simply power off the device now to exit learning mode. If you do want to enable inversion, tap

the learning mode jumper again. The LED will start fading out repeatedly with a period of 1 s.

6. Power off the device to exit learning mode. Your learning mode jumper connection should be

removed at this point. The settings you chose have been saved in non-volatile memory of the

device and you can power it on to use the new settings.

9.2. Restoring the Default Settings

This section gives steps for restoring the switch to its default settings. This is a good thing to try if you

have any trouble using the switch. The general configuration procedure is documented in Section 9.1,

but the instructions here are easier to follow if you just want to restore the device to its default settings.

To follow these instructions, you will need to know how to connect and disconnect the learning mode

jumper, as described in Section 9.

1. Get the device into learning mode. In order to do this, power off the device, connect the

learning mode jumper, and then power it on. After it is powered on, you should disconnect
