No More Fights over the COM Ports Unlike other home automation interfaces, which use the slower RS-232 communication protocol, the PowerLinc Controller transfers data at much higher speeds. Best of all, it plugs into any USB port or expansion hub so there's no need to plug and unplug other peripherals like PDAs, scanners or printers when you need to update the programming. In fact, many new computers, in particular laptops, don't include serial ports any longer, which will make using serial-based interfaces expensive and difficult to use. Don't Block your Outlets PowerLinc Controller includes Smarthome's innovative pass-through AC outlet on the front of the unit. This outlet that allows you to plug in additional AC devices. While the outlet doesn't have any control features, it really helps against "power strip buildup". Safety Tested and Factory Certification The PowerLinc Controller is safety tested and approved.
