Modular electronic apparatus for distribution of satellite signals
The application relates to modular electronic apparatus ( 1 ) for distribution of RF communication signals. The apparatus comprises a chassis ( 2 ) arranged to removably receive plural modules ( 3 ), at least some of which are arranged to receive and process RF communication signals. A communication path ( 17 ) is provided for modules to communicate with each other and/or with the chassis. Plural modules received in the chassis. When a module is received in the chassis, it is arranged to broadcast a message over the communication path indicating its presence in the chassis and its type. At least one other module is arranged to adapt its behaviour in response to the message.
1. A modular electronic apparatus for distribution of RF communication signals, comprising:
a chassis arranged to removably receive plural modules, at least some of which are arranged to receive and process RF communication signals;
a common bus for modules to communicate with each other and with the chassis; and
plural modules received in the chassis,
wherein the chassis has a processing unit arranged to provide a user interface for the apparatus,
wherein when a module is received in the chassis, it is arranged to broadcast a message over the common bus indicating its presence in the chassis and its type and capabilities in processing RF communications signals including services providable to other modules in the chassis, wherein the processing unit is arranged to register the module in response to receiving the message over the common bus and has no prior knowledge of a module type and its capabilities, wherein at least one other module is arranged to adapt its behavior in response to receiving the message over the common bus,
wherein a module inserted into the chassis and registered is arranged to provide a sub-user interface defining which information relating to the inserted module and controls for configuring the inserted module are to be displayed, and
wherein the processing unit is arranged to request and receive the sub-user interface relating to the inserted and registered module over the common bus and to render the sub-user interface into the user interface such that a user is presented with information relating to the inserted and registered module and controls for configuring the inserted and registered module via the user interface and wherein in response to the user selecting one of the controls the processing unit communicates with the module over the common bus to cause a selected configuration of the module.
2. The apparatus of claim 1 , wherein when a module is received in a slot in the chassis, and registers with the processing unit, the received module is shown and becomes selectable in the user interface generated by the processing unit, and when the user selects the received module in the user interface, the processing unit requests the sub-user interface from the received module and renders it in the user interface.
3. The apparatus of claim 1 , wherein the user interface comprises webpages, the processing unit provides a webserver arranged to serve at least one webpage associated with the chassis, and comprises a module web proxy server to request a respective website from modules registered with the processing unit to provide sub-user interfaces for those registered modules.
4. The apparatus of claim 3 , wherein the processing unit is configured such that the processing unit renders the respective website from the modules in the user interface.
5. The apparatus of claim 4 , wherein the processing unit is configured such that the processing unit renders the respective website from the modules in the user interface as received without modification.
6. The apparatus of claim 1 , wherein at least one module has configurable capabilities as one or more of: a power supply, a cooling module, and a reference frequency generator.
7. The apparatus of claim 1 , wherein at least one module has configurable capabilities regarding at least one of: an amplifier, am attenuator, an RF filter, a signal generator/source, switches, switch matrices, frequency converters, RF over Fiber modules, couplers and RF monitors, splitters and combiners, or equalizers and slope compensation modules.
