I’m trying to build a wireless remote control, and settled on the ES Tx/Rx pair from Linx. All I want is to feed a “high” to the data in on the Tx, and get a corresponding “high” on the Rx, simple OOK on and off. The goal is to have a single pushbutton on the Tx, which, when pressed, will cause a transistor to turn “on” in the Rx (effectively pressing the “hacked” pushbutton on the device to be controlled).
Looking at the Rx datasheet (http://www.linxtechnologies.com/resourc … xxx-es.pdf), it states that in the absence of a valid signal, the Data output can switch randomly. This is obviously not acceptable. Page 9 in the datasheet show a squelch/hysteresis circuit that should take care of that, but it appears to get its “data” from the audio pin, not the data pin. Is this correct? Will this work for the simple on/off that I want? Or should I just use the data pin instead? Or some other circuit entirely?
Thanks,
Juliean.
