Hello,

If it works when powered by USB, then it looks that it is the 12V to 5V regulator is not working. Are you able to measure a DC voltage with a multimeter?

I wait for your feedback. Please send me by email the model (TH or SMD) and date of purchase.

Regards, Luis

Hello Stephane,

As far as I know WiFish uses WiFi but does not sends Nmea0183 data. The multiplexer only can receive or transmit Nmea0183 data. You should use the Raymarine app to see the sonar data.

Hello Fab,

I assume you connected the black (noir) wire to screw terminal B2. You did not confirmed this.

Also I see 19200 as the baud rate on port P2. This is very strange. Normally chartplotters use 4800 or 38400. Did you setup your charplotter to send data at a speed of 19200?

Hello Fab, J'ai besoin de lire les manuels... I need to read the manuals of your instruments/equipment to understand your setup. Also a screenshot of the multiplexer webpage would help. I understand that you want the Garmin plotter to send data to the multiplexer on port P2. So you need to connect b...

Hello, I was reading the VHF manual and it is a bit confused. As far as I could understand AIS data is sent on Yellow/White wires. Assuming you want to receive AIS data on the P1 input port of the multiplexer, you should connect Yellow to A1 and White to B1. You should set P1 baud rate to 38400. And...

Hello Pascal, I follow your link and then went to the manual of your VHF/AIS. It is a very poor manual in my modest opinion. As far as I could understand there is a "cable" with 2 ends. One end connects (or is it fixed to the back of the radio?) to a socket on the back of the radio. The other end ha...

Hello Loic,

Thank you for your review. I have decided to flash the ESP32 modules that I include in the kits to avoid what you describe. Still if you want to use the USB port as an input or output of the multiplexer you need to install the CH340 driver.

Hello,

This is a description of the ESP32 Development Board used in the KIT and TH versions of the NMEA3WIFI and NMEA4WIFI multiplexers.

Hello, I created this forum so that you can write a review and express your satisfaction (or not) with my work. The forums dedicated to the existing 3 multiplexers are related to support. The topics mainly describe problems that the users face when they install or operate their multiplexers. If pros...

Hello, I really suggest that you test your multiplexer before installing it on your boat. You will learn about it and you will make a more confident installation. The 1st thing you can do when you receive a multiplexer (this is general for all the models) is to use a USB cable and power the multiple...
