Abstract

Electrical equipment is provided with an upgradable communication converter module in the form of a printed circuit board. The module is plugged into a communication converter module receptacle on the equipment for providing communication exchange between the equipment internal communication system and an external communication network. The communication converter module printed circuit board contains a network protocol interface, an isolated interface, a protocol converter, and an internal protocol interface.

Claims

1. A communications converter module comprising:

an edge connection having contacts at one end for securely and removably mounting and coupling the communications converter module into a socket of an electrical equipment apparatus adapted to receive the communications converter module the electrical equipment apparatus having an internal communications system electrically-coupled to said socket, said socket being electrically-coupled to a network communications system;

a network protocol interface circuit on said module electrically-connecting with said contacts and arranged for electrical connection with the network communication system via the socket when the communication converter module is mounted in the socket;

a protocol converter circuit;

an isolated interface circuit on said module electrically-connecting between said network protocol interface circuit and said protocol converter circuit; and

an internal protocol interface circuit connecting with said protocol converter circuit and with the internal communication system via the socket when the communication converter module is mounted in the socket, whereby said network communication system and said internal communication system exchange communication therebetween.

2. The communication converter module of claim 1 wherein said module comprises a printed circuit board.

3. The communication converter module of claim 1 wherein said contacts are adapted to be received within a single in-line memory module connector.

4. The communication converter module of claim 3 wherein said memory module connector is attached to electrical equipment.

5. The communication converter module of claim 4 wherein said memory module connector has a U-shaped configuration defining receptacle means within a front part thereof for receiving said contacts thereby providing electrical and mechanical connection with said communication converter module.

6. The communication converter module of claim 4 wherein said memory module connector includes a plurality of pin connectors extending from a bottom surface, said pin connectors providing electrical connection between said communication converter module and associated electrical equipment.

7. Electrical equipment coupled to an external network communication system having a network protocol, the electrical equipment comprising:

an internal communication system having an internal protocol; and

a socket electrically coupled to the external network communication system and to the internal communication system and for receiving a communications converter module comprising;

an edge connection having contacts at one end for securely and removably mounting and coupling the communications converter module into the socket;

a network protocol interface circuit electrically coupled with said contacts and arranged for electrical connection with the network communication system via the socket when the communication converter module is mounted in the socket;

an isolated interface circuit electrically coupled with said network protocol interface circuit;

a protocol converter circuit electrically coupled with said isolated interface circuit; and

an internal protocol interface circuit electrically coupled with said protocol converter circuit, and with the internal communication system via the socket when the communication converter module is mounted in the socket, whereby said network communication system and said internal communication system exchange communication therebetween.
