Converter/multiplexer for serial bus
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.
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;
transmitting using a second transceiver the second serial bus output to a Controller-Area Network (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,
receiving at a second multiplexer/converter the first serial bus output; and
converting the first serial bus output back to multiple parallel inputs,
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 a mode of transmission based on a programmed default configuration.
2. The method of claim 1 , wherein the step of transmitting the first serial bus output includes a step of selecting a mode of transmission based on an existence of a hardwire connection.
3. The method of claim 1 , wherein the plurality of parallel inputs are further converted by the first multiplexer/converter into other formats using device driver.
4. The method of claim 1 , 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 device drivers.
