Simplex Radio "R" throttles and receivers available for use in U.S., Canada, Australia and New Zealand only.

For LocoNet connectivity, there are 2 RJ12 connectors at the back for daisy chaining to other LocoNet devices, and one RJ12 connector at the front to provide a professional look when mounted to a panel.
