How it works: X10 home automation has been around for many years and it's very popular due to easy to install and maintenance. X10 utilize house power lines to send and receive signals so no more wires are needed to install basic X10 system. With popularity of cellphone texting message services, we offer X10 modem which has capability of receiving and sending X10 signals from and to any cellphone anywhere. X10 GSM modem need to use GSM networks. In United states, AT&T and T-Mobile has offered a prepaid plan as low as $15/month for unlimited texting. They will provide SIM card which has to be activated before using with X10 modem. To receive X10 data, we can use any cellphone regardless the networks such as Verizon, Sprint, Metro PCS beside AT&T and T-Mobile.
(SEE PICTURE ABOVE) When X10 wireless motion dectector such as MS16A detects moving object, it will send X10 radio signals to X10 transceiver (TM755). Assuming that MS16A already been set/programmed as House code A Unit code 4.
The signal propagate through power lines and received by Powerlinc 2413S serial interface and then converted to serial data to X10 GSM modem. The X10 serial data decoded by modem then will be transmitted using SMS/texting services. The recepient will see "A*4_ON" on his/her phone.
To activate X10 module such as AM466 ( for example it was programmed as House code A and Unit code 7) we send text as follows "A7TON). This command will be received by X10 GSM modem and converted to standard X10 signals by 2413S then distributed throughout power lines. This signal will activate a relay inside AM466 module to turn on a light bulb.
