Patent Images
1. A fuel transaction tracking system at a first location having a fuel transaction data system with a four wire legacy configuration, a four wire remote station at a second location, and two underground communication wires positioned between the first and second location in a current loop comprising:
- a) an active multiplexing/demultiplexing unit having active power and two data inputs and two data outputs actively connected to the four wires of the fuel transaction data system and a two wire output for connection to an end of the two underground communication wires;
b) a passive multiplexing/demultiplexing unit having a two wire input for connection to an opposite end of the two underground communication wires and a four wire data output for connection to the four wire remote station comprising a first and second bidirectional current loop connected to the four wire remote station;
c) wherein the active and passive units are actively connected from the two wire output to the two wire input via the two communication wires; and
d) wherein the system is capable of multiplexing/demultiplexing four wire data to and from the fuel transaction data system and the four wire remote station via the two underground communication wires set up as a current loop.
