I was puzzled at first by the word 'inferred', until I realized you meant 'infra-red', or IR. Okay, now there is something I need to explain to you:
Except for the modules that are designed to work with RF transmitters (hand-held palm controllers, key-chain transmitters, etc), X-10 is not an RF system.
X-10 controllers actually send specially-coded signals (
not RF) over the power circuits in your home. Table-top controllers, some wall-mounted keypads, etc. are examples.
The modules and wall switches/dimmers receive these signals and respond by switching or dimming your loads. Only the modules with antennas receive RF signals.
The IR-543 is a table-top controller that also receives IR commands and 'translates' them into the same X-10 signals (again, not RF), and sends them over the power wires.
If the RC-5000 is an IR remote, the IR-543 will suffice. If it's an RF remote, you need an RF-receiving module, with an antenna. (Some remotes do both IR and RF.)
