The unit ships with a copy of Home Control Assistant (HCA) software (see HomeToys review) and set-up took only a few minutes. Just plug it into the wall and serial port ... install the software ... and test the operation. HCA has a menu option that lets you test and configure the PLC. A very nice feature allows you to adjust the transmission power and receiver sensitivity. This will be appreciated by those with less than ideal wiring situations ... i.e. everyone :-(

You can buy the LynX-10PLC with Marrick's LynX-SOFT-Lite software for $99 or the LynX-HOME (with AQT's Home Control Assistant software) for $159. Marrick has been around for many years making dependable products and I expect this will be a welcome addition to the X-10 world. Check it out at www.marrickltd.com/LynX105.htm .
