If the Ethernet interface is connected to the Internet it enables you to add remote locations like your holiday home to your Home Automation system or control and check the home of your grandmother.
All existing Home Automation software that runs on a Windows platform and has interfacing software for the W800RF receiver or the RFXCOM receiver can use the RFXCOM Ethernet interface without any modification in the HA software thanks to the CPR (COM Port Redirector) software. This CPR software emulates a standard COM port in Windows.
On other platforms like Mac and Linux, the communication protocol is via TCP/IP with the receivers and transmitter. Of course, TCP/IP communication is also possible on the Windows platforms.
All RFXCOM receivers have a W800RF compatible receiving mode and the RFXCOM receivers translate all received non-X10 RF packets (like Visonic, SecureLinc, KlikOn-KlikOff, Domia Lite) to an equivalent X10 packet. This makes it possible to process those non-X10 sensors and remotes by all X10 oriented Home Automation software without any modification in this Home Automation software.
There are 4 different types of RFXCOM Ethernet interfaces.
1. LAN with 1 COM port and connections for 1 or 2 receivers OR 1 transmitter,
2. WLAN with 2 COM ports and connections for 1 or 2 receivers AND 1 transmitter,
3. LAN with 2 COM ports and connections for 1 or 2 receivers AND 1 transmitter,
4. WLAN+LAN with 2 COM ports and connections for 1 or 2 receivers AND 1 transmitter.
