This is the general procedure for configuring the device. To follow these instructions, you will need to know how to connect and disconnect the learning mode jumper, as described in Section 9.
- 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, disconnect the learning mode jumper. At this point, you will see the indicator LED fading in and out with a period of 1 second. Your device is now in learning mode, and will be until you next turn off the power. In learning mode, it will not turn on the relay. If you want to abort learning mode, you can power off the device at this point and none of your settings will change.
- Tap the learning mode jumper (connect it and then disconnect it). This restores all of the settings in the device to their default values; the threshold will be 1696 μs and inversion will be disabled. The indicator LED should be blinking a different pattern now. If you want to use the default settings and exit learning mode, you can power off the device at this point and skip the instructions below.
- 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.
- 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.
- 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.
- 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.
