  • Send X10 signals
  • Develop your own X10-compatible products for sale without the cost of UL approval

Essential Info

If you know how to send and read RS232-type serial communication with your computer or from any other electronic device, you can develop and market your own software and/or hardware for use with X10-compatible systems without having to develop your own X10 communications hardware or having to go through costly UL approval. This module is optically isolated and UL approved. The timing-critical nature of communication with this device requires low-level hardware programming experience. It may also require dedicated microprocessor time. Thus, it is not recommended for casual programmers.


What's Included

  • X10 TW523 Interface Module Transmitter PL513/PSC04
  • More Info

    You can even make this device a wireless interface! The All-Housecode RF Transceiver (sold separately) contains everything you'll need to add wireless capabilities to the X10 TW523 Two-Way Interface Module.

    For X10 two-way only applications: If your application needs to send and receive X10 signals and does not need to read X10 signals, then order the X10 TW523 Two-Way Interface Module.

    Make sure to add a 10K pull-up resistor to the zero crossing signal - spent hours of debugging before figuring this out. If using an Arduino, do this in setup() to turn on internal pull-up resistors: pinMode(zcPin, INPUT); digitalWrite(zcPin, HIGH);

    Item received quickly and works as expected.
    ELFADIL -- hawthorne, CA   8/15/2010
    Easy to instal and drive with a BS2sx MCU. Work well with PRO X10 16-Device Plug-In RF Base, However not with my pre-existing X10 Powerhouse on 120 VAC/ 50 Hz electrical supply.
