Welcome to HTH's PLM-24 section. Our mission is to develop products thats can be used in
the home
automation field as well as other control systems. The products currently available
is aimed at electronics
and HA enthusiasts looking for inexpensive and easy-to-use tools to turn
their own ideas into reality. Our
products are also well suited for educational purpose in above mentioned fields.
Take your time around our web-site and you will find lots of ideas and examples you can
download and
there is more to come so if you are into this field bookmark this page

The USB EasyTap module is a generic USB < > serial converter and provides a painless way to get your
project interfaced to the otherwise complex USB port on your PC. No need to worry about writing your own
device drivers since they are included. Can be used to interface our PLM-24 and lots of other things.

PLM-24 is a low cost and easy to build power line modem
that let you send and receive serial data up to
2400 bps over the mains as easy as 1,2,3! Designed as a small plug-in module to be used in new or existing
designs. Can easily be interfaced to any PC or microcontroller and doesn't need any special or expensive
development tools.

PLM-24 DevBoard will get your PLM-24 applications up and running in a shorter time. Includes power
supply and a large prototype area for your own applications. The PCB is designed to fit in a standard plastic
case available from several different manufacturers with or without AC plugs according to the standards of
different countries.

This gateway will let you branch your PLM-24 network to twisted pair cables and this way keep the node
cost down to a minimum! The average cost of a simple RS-485 node is very small so you will be able to
expand your network even if you are on a budget!
