Shared, Switched RF Link Enables Multifunction Remote Control For Different Roles

摘要

In many industrial and commercial situations, there is often a need to energize or de-energize equipment that is remotely located or select one of two modes of operation for the equipment. This can be done via a hard-wired, RF, or even audio link, each with advantages and disadvantages in cost, reliability, maintenance, ease of installation, and longevity. For this application, a physical link was possible but difficult, so a wireless system was chosen.
