True wind speed
Hi I just fitted the mux in replacement for a raymarine seatalk nmea bridge. I have a mixture of devices from raymarine and furuno. I have a furuno reapeater, multi function instrument. It graphs the wind speed which I find very useful. After installing the new mux this no longer works. I notice it plots the true windspeed. My question is does the mux decode the true windspeed from the sealtalk bus? (Or is it calculated). The raymarine bridge seems to present this info as Nmea, but the new mux does not. I've not fully investigated it yet but I think it is the sentence Vwt. A second question I have is when logging the nmea to a txt log file on windows where is this file saved? Thanks Johnathan.
NASA-CLIPPER-WIND to NMEA converter
Hello, a friend of mine asked me to build a converter to connect his NasaClipperWind to ST4000. First I thought it would be an easy trip ...just transform the different data formats of MVW to VWR. But it was an very old NasaClipperWind - without NMEA output. So I captured the data from the daugther display connector. Finally this little gadget updates the old NasaClipperWind to speek NMEA. Maybe it's interesting for those people still using this NASA devices... Matthias

wire converteur USB to COM Red Wire == VCC, (+5V) Black Wire ==GND Green Wire == TXD White Wire == RXD
I don't have that USB converter - but from what I read from the Internet, I think you have changed green and white. Green is TxD from USB. Here Data comming from USB are sent out. White is RxD to USB. Data received here are sent to USB. So - when the Bridge sends data on it's TxD pin, this data should be received by the converter on it's RxD pin ( White ) - when the converter sends data on it's TxD pin (green), this data should be received by the Bridge on it's RxD pin. Alltogether -> [code:1:3b3943f7b9] USB Converter <-> Bridge Red Wire <-> VCC, (+5V) Black Wire <-> GND Green Wire -> RxD White Wire <- TxD [/code:1:3b3943f7b9] Cheers Frank
bridge 2 outpout
hello i try to connect nmea outpout on the bridge with USB To RS232 TTL UART PL2303HX Auto Converter USB to COM i have connected only wire green and white on the exit nmea outpout but i receive nothing the other connection rs232 was good i receive good data but i want to have 2 output with the bridge wire converteur USB to COM Red Wire == VCC, (+5V) Black Wire ==GND Green Wire == TXD White Wire == RXD thank you
New software functionnality
Hello, Today I setup filters on my multiplexer. It's really easy to use and what a pleasure to have all data showing on my external big display. No more data congestion :!: By the way, I just think about a new function that can be include in the software. Now you can filter or rename NMEA sentences. It would be nice to be able to "calibrate" them. For exemple to add 0.45cm at the DPT sentence. Or to add few degrees at nmea sentences sent by the mast head sensor (alignement). By the way you should rename this product : 5 in/ou NMEA Multiplexer as USB works as data in and out.
oppen skipper seems to have alot of what you want, the only downfall is that it works with a 300euro interface for now, they are working on a connection with an elm327 canbus bluetooth... I'm interesed in see what happents on the nmea 2000 networks but maretron seems to be the only producer that has an analiser... since is a canbus comm it should be posible to see and decode all the messagess from a com port...
here are the service manuals and more...
Opto isolated RS232 cable
I use a pc with Opencpn as navigational software. Data stream is managed by gadgetpool mux except for AIS data. For AIS, connection is direct to the pc RS232. I just solder nmea wires directly on the RS232 plug. And today I found this http://www.actisense.com/products/nmea-0183/opto-4/opto-4.html I was ready to buy such product but not for 75 € ! It might be a good idea to add this product on the online shop. I also found a diagram on sailnet site. Composants cost less than 5 € :roll: I'd like to share it with you but I don't know how to add an image to this post.
I reply to this old post But I just installed my new mux, in replacement of a Brookhouse model. Clearly gadgetpool mux is far better than other commercial mux. And support is exceptionnal I should have bought this mux at first time !
