Opto-coupler Design Notes

Hello, In this article I explain the design methodology in the opto-coupler inputs of the NMEA2WIFI multiplexer. This type of input is not strictly necessary but it is very useful when the talker and the listener(the multiplexer) do not share the same ground or when due to noise, a voltage differenc...

Re: Using with Nasa Clipper Instruments

Hello Stuart, As you can imagine I have not the possibility of testing the multiplexer with all possible instruments. I have a Nasa AIS on my boat whose Nmea183 output was connected to my chartplotter. When I connected the AIS simultaneously to the chartplotter and to the P2 input of the multiplexer...

Re: Interface with Standard Horizon CP180

I have set port 1 as an input to the CP180 on port 1 input - this doesn't give much as the CP180 will only allow limited NMEA sentences. Hello, I am a bit confused on what you mean. You said before that your aim was to send way points to the CP180. Before you got the multiplexer, were you able to d...

Re: Interface with Standard Horizon CP180

Hello Michael, I just read the CP180 manual. The information about Nmea183 ports is scarce. But looking to examples and because each port (be it input or output) has only one line, I assume that the CP180 Nmea outputs and inputs are single ended (like RS232). And your post confirms that, since you h...

Re: Connecting a JGTech Autonnic Wind Sensor and App to Use with it.

Hello, I am glad you get it working and thank you for the recommendation. I use SeaWi for Android which can show different data including AIS. I am not sure if are looking for an App to show only wind data. Unfortunately SeaWi can not be set to show wind data only. I hope you find a good App! Regard...

Nmea2Wifi in Kit Form

Hello, From mid February, it is available a version of the Nmea2Wifi multiplexer as an electronic kit. It is available in Ebay for a price of 30 euros, including worldwide shipping postage. The Assembling Manual is available here: The front page of the manual The back page of the manual Regards, Luis

Re: Connecting a JGTech Autonnic Wind Sensor and App to Use with it.

Hello, Sorry for not answering sooner but I had not the NMea2Wifi forum subscribed :oops: I read the datasheet and the manual of the wind sensor. I must say that I have no idea how you can change the settings of the wind sensor by writing into its input nmea port. I see a diagram to connect it to a ...

Re: Bidirectional Multiplexer

Hello John, Thank you very much for your post! My first comment is that I thought I had changed the forum settings to allow posts by registered users (registration accepted by me) without my previous approval. In fact I come here from time to time to delete "new registered users" waiting from my app...

Re: Bidirectional Multiplexer

Hello John, Thank you for the suggestion which is most appreciated. Yes it can be done as it is only software. The easier way for me to do that is to add a check box in the main (and single) web page interface . It could be called "Simulation Mode". If the box is checked, the multiplexer would ignor...

Using the NMEA2WIFI multiplexer to test a talker!

Hello, I was asked how the Nmea2Wifi multiplexer could be used to display NMEA sentences coming from a talker device. Here is a possibility using the free Windows programme called "Packet Sender". If you google it you will find the link to download. This is a powerful program to send/receive packets...
