Abstract of the Disclosure The invention relates to a method and an apparatus for remotely controlling device, more particularly to a system and method for controlling locomotives in a railway environment using radio frequency signals. This invention makes use of a remote operator programming unit (OPP) to set address information in the transmitter unit via a communication channel such as an infrared link. The use of the operator programming unit allows eliminating the need to open the casing of the transmitter during programming thereby reducing the probability of damaging the electrical components of the transmitter. The invention also allows assigning a unique address to a transmitter/receiver pair in a remote control system. The invention further provides an apparatus for remotely programming a transmitter unit.
