Such an orientation minimizes the risk for water leaking through the connector seal.Ĭonnector placement is a tight fit. That allows the enclosure to be mounted on a wall connectors facing down. I prefer having the connectors both on the same short edge. You need to decide where to place the connectors on the enclosure. The end result is a bit hacky but good enough for government work! Drilling holes To make the big PG9 cable gland grip on the thin USB cable, I wrapped a few rounds of PVC tape over the cable. I had to drill out the internal collar on the cable gland and enlarge the hole on the gland cap nut.
Using a cable gland with a ready-made cable is a fiddly process, though.
That’s the option I chose, mainly because I hadn’t yet received the panel connector shipment I was waiting for. For NMEA 2000, a standard M12 micro connector is used.įor the USB connector, the preferred option is to use a ready-made micro USB panel connector:Īnother option would be to use a cable gland to route a micro USB cable to the enclosure. We need to connect the device to both NMEA 2000 and USB. We’ll use the standard waterproof SH-ESP32 enclosure for this project. OLED display (optional) Hardware assembly Required accessories.USB panel connector (soon to be available at hatlabs.fi) or a PG9 cable gland.To complete this tutorial, you need the following parts: If you have any suggestions, corrections, improvement ideas, or other feedback about this tutorial, I’d love to hear about them at Parts needed
HOW TO TEST NMEA 2000 NETWORK SOFTWARE
The NMEA 2000 gateway could be used to interface any major PC based navigational software with your NMEA 2000 network, or to connect a Raspberry Pi based Signal K server to the NMEA 2000 bus, or even to diagnose NMEA 2000 issues with suitable software. The resulting device is an isolated NMEA 2000 gateway that will both read and write NMEA 2000 packets and allow your computer to interface with your boat electronics. Thanks to the SH-ESP32’s integrated CAN interface, no external hardware is required.

In this tutorial, I’ll show how to build an Actisense™ 1 NGT-1 compatible NMEA 2000 USB gateway with an SH-ESP32 and a couple of connectors.
