Data bus for a plurality of nodes
First Claim
1. A data bus arrangement for a plurality of nodes connected to each other, said arrangement comprising:
- a logical decision gate having a plurality of inputs corresponding to said plurality of nodes;
at least one converter module connected between said plurality of nodes and said logical decision gate, each convertor module converting an optical output from one of said nodes to an electrical signal which is fed to one of said inputs of said logical decision gate;
a plurality of switching means, each switching means connected between an output of said logical decision gate and an input of one of said convertor modules for controlling said convertor module independent of an output signal on the output of said decision gate.

Abstract
A data bus arrangement for a plurality of nodes connected to each other including a logical decision gate having a plurality of inputs corresponding to the number of nodes. A converter module is connected between each node and the logical decision gate. Each convertor module converts an optical output from one of the nodes to an electrical signal which is fed to one of the inputs of the logical decision gate. A separate switch is connected between an output of the logical decision gate and an input of each one of said convertor modules for controlling the convertor module independent of an output signal on the output of the decision gate.

3. A method for controlling communication among a plurality of data nodes, comprising the steps of:
-
providing a decision gate having a plurality of inputs corresponding to said plurality of nodes;
providing at least one convertor module connected between said plurality of nodes and said logical decision gate, each convertor module converting an optical out from one of said nodes to an electrical signal which is fed to one of said inputs of said logical decision gate;
outputting a signal from said logical decision gate to an input of each of said convertor modules;
providing a plurality of switchable control means, each of said plurality of switchable control means connected to one of said convertor modules for controlling said convertor module independent of an output signal on the output of said decision gate.
