Ground Loops and Galvanic Isolation

Hello, All Vela-Navega multiplexers have Nmea0183 opto isolated inputs ports and a Nmeaa0183 differential output port. If we need to connect the Nmea0183 output port to a Nmea0183 listener, we need to know if the listener has an opto isolated input. If the listener has a single ended input we should...

Re: V6 with NMEA tool

Hello, I am sorry to say but that took is now obsolete. In order to update software present multiplexers use a process described here https://www.vela-navega.com/index.php/update Please tell me which is your present firmware so that I will check if you need any special instructions. Regards, Luis

N2K0183 Hardware Test

Hello, We describe here a test that you can make in the case that you need to be sure that all the hardware of the N2K0183 multiplexer is working without problems. This test checks the operation of the Nmea0183 output port P2, the Nmea0183 input ports P1 and PX, and the CAN bus transceiver. You can ...

Re: Can I use an NMEA2WIFI for something custom ?

Hello Boris, If you flash with a custom binary and want to return to nmea2wifi you the same problem as if you need to change the ESP32 module in a TH unit. There is a small OTA program in the forum that you can flash the "destroyed" EEPROM and then you can do a OTA flash of the nmea2wifi binary. If ...

Re: Can I use an NMEA2WIFI for something custom ?

Hello Boris,

I see no problem. You have the schematics. I do not understand why you need to use OTA. You could just flash your binary using the serial port and Arduino.

Re: Connect to External network

Hello, If you choose the multiplexer to connect to an external network (say a router with internet connection) you can on smartphone (or else) connect to: 1) the Nmea4Wifi AP but you cannot link to the Internet or 2) the router and have access to the internet. In order to to access the multiplexer f...

Re: Wave jamming

Hello,

Yes. You can run present firmware in the old hardware.

It could be useful if you could temporarily feed power from a cheap 9V battery to see if the FM interference exists. The idea was to check if the interference comes through the common 12V service battery.

Re: Wave jamming

Hello Schanpsy, Sorry for this late answer. As you probably know all multiplexer use a switching voltage regulator to bring the 12V voltage from the service battery down to 5V. Everything works from 5V directly (namely the 485 driver) or from 3V3 (reduced from the 5V through a linear AMS1117 regulat...

Re: Windows 11 Connectivity

Hello Adam,

Could you run this tool


https://vela-navega.com/forum/viewtopic ... ester#p482


and check if you receive UDP data from the multiplexer? Placing the multiplexer in simulation mode.
