RR501

From HomeSeer

The X10 RR501 (and equivalent OEM versions such as the IBM HD501) combine an X10 Applicance (relay) Module and an X10-RF to X10-PLC bridge. The integrated relay module responds to both RF and PLC commands. The RR501 contains no memory or logic; the X10 device for that is the CM11A.

The RR501 operates on a single housecode, and itself uses one of the device codes on that house code - either 1 or 9 depending on a slide-switch. Even when the RR501 is the target of the code (e.g. G1), it will still also broadcast that same signal on the powerline.

The TM751 serves a similar purpose with some limitations.
