Abstract
The present invention concerns systems in which a plurality of device can be monitored. More particularly the invention concerns a monitoring system particularly though not exclusively for light dimmers in which requests for data are inserted into the gaps of periodic firing signals so as to trigger responses. Examples include dimming systems for use in theaters and in television and film studios.
