An interesting thought - the mux would usually expect the USB to be connected to a computer with drivers and software but maybe this would work. I assume that power is not supplied out of the multiplexer as it is normally expected to be connected to a computer . additionally power to the multiplexer is not through the USB either.
There is GPS NMEA software capable of doing the filtering/versioning to different NMEA versions but would need to have the computer available at all times to act as the multiplexer. Cheaper ( assuming you had a computer already aboard ) and workable if you continuously have it on for other navigation purposes. In my case I have a Shipmodul wifi mux with NMEA inputs from my GPS and AIS receiver and outputs to the VHF ( wired ), USB if I wanted, and wireless to my iPad with iNavx and some AIS apps and laptops where I happen to run NavMonPC and other tools to look at the NMEA sentences and such. I'm working on getting the instruments ( older Comnav/Nexus ) into the entire ecosystem - I think I might have problems being successful with this. The ShipModul multiplexer doesn't have NMEA version conversion but supports your typical functions found on most of these devices. ed _____ From: [email protected] [mailto:[email protected]] On Behalf Of Dennis C.

Would a Globalsat BU-353 USB GPS adaptor connected to a Brookhouse multiplexer through its USB port work? Would the sentences be sent through the multiplexer to the users? Does the multiplexer USB port have power for the BU-353 like my laptop? Not sure why one would want to do this but curious if it would work.

I had a similar problem trying to get gps sentences working from an older fixed gps to a new Uniden VHF. I took a cheaper option and bought a small handheld Garmin and connected to the VHF NMEA wiring. Were I to do it again I might get a standalone GPS receiver ( maybe a globalsat BR355 or similar ) which would power up with the VHF. A $60 solution but needs a 5v power supply.

Has anyone ever done this, or know of a place that sells these?
