ABSTRACT:
A central control system that monitors and remotely controls one or more terminal devices which may be part of an apparatus such as an imaging machine. Each terminal device communicates with the central control system at a predetermined time and relays the operational conditions of the apparatus to which it is associated. Relayed conditions may include information such as the number of imaging operations performed in a period of time. The central control system controls each of the terminal devices in accordance with the information transmitted from each of the terminal devices. The central control system supervises incoming transmissions from the terminal devices and detects when a terminal device has not communicated at its predetermined time. When this condition arises, the identity of the non-reporting terminal, as well as the predetermined time it was to have contacted the central control system, are displayed at the central control system.
