Abstract

This disclosure relates to a converter/multiplexer and associated method of use therefor or converting and multiplexing parallel inputs, a modem, a GPS, or even modem information into a single multimaster broadcast serial bus standard for connecting electronic control units, and more specifically, to a multiplexer for transforming analog, digital, frequency, GPS, or modem inputs into a CAN bus data transmittal over LAN and/or PAN and interrelation with a similarly equipped receiving module. Further, the converter/multiplexer is used alone or in a group as part of a larger system for multiplexing and demultiplexing signals for serial bus processing and also for guidance when the converters are cabled by operators using stored configurations.

Claims

1. A method of converting a plurality of parallel inputs to a plurality of buses, the method comprising the steps of:

collecting a plurality of parallel inputs at a first multiplexer/converter;

converting the plurality of parallel inputs into a first serial bus output;

converting the plurality of parallel inputs into a second serial bus output;

transmitting using a first transceiver the first serial bus output to a serial bus; and

transmitting using a second transceiver the second serial bus output to a CAN bus over either of a local area network protocol, a personal area network protocol, a low-power digital radio protocol, or a hypertext transfer protocol either over a hardwire or a wireless connection.

2. The method of claim 1, further comprising the steps of:

receiving at a second multiplexer/converter the first serial bus output; and

converting the first serial bus output back to multiple parallel inputs.

3. The method of claim 2, wherein the step of transmitting the first serial bus output includes a step of selecting the mode of transmission based on an existence of a hardwire connection.

4. The method of claim 1, wherein the plurality of parallel inputs are further converted by the first multiplexer/converter into other formats using drivers.

5. The method of claim 2, wherein the step of converting the first serial bus output back to multiple parallel inputs includes a step of further converting the inputs into other formats using drivers.

6. The method of claim 2, wherein between the first multiplexer/converter and the second multiplexer/converter is a hardware connection and a wireless connection for the transmission step, and the method further includes the step of selecting the mode of transmission based on a programmed default configuration.
