The W800 (full name W800RF32A) is an X10 wireless receiver from WGl Designs

• The W800 is a serial device and requires a USB Serial adaptor.
• Since it is a serial device you can connect multiple devices to XTension at the same time to improve reception or coverage.
• The W800 receives standard X10 devices, remotes and motion sensors as well as the security devices, door sensors, motion sensors and security remotes.
• The W800 has a coax connection for the antenna and so a higher quality antenna can be used.
• The picture shows the W800 as attached to my board in my data closet via cable tie on a pegboard.
