power supply to 522iGPS

[goose89]

Gonna try to keep this as simple as possible.

I'm going to install a 522i on the rear portside of my 175 Alumacraft TP console boat. I've got a 38 and 520 networked together on the console and bow from a GPS "puck" on the rear starboard side.

I got the 522i (rather than networking another 520 in) so I could use it as a "portable" unit if I wanted in the future.

Question is, do I need to supply power to the NMEA 2000 wires?? The manual has 2 different diagrams / ways to supply power to the units. It states the NMEA 2000 bus MUST be connected to a power source to operate NMEA 2000 devices, including GPS modules, which draw their power from the network bus.

I hooked up just the power cable and it fired up and GPS aquired position after initializing. ??? Seems like I may not have to power up the NMEA wires. But manual seems to say something different.

Maybe I'm reading it wrong, and they mean a "puck" or remote antenna. I don't know. The manual is a 522i / 527i which are both INTERNAL antenna models. I'm confused, which is normal.

Any help appreciated in advance.

If you're not going to network the unit then I don't believe you will need to connect power to the NEMA wires. If you decided to create another network which is standalone from the other network (the 38/520 is network #1) then you would have to. If it's working then you should be good to go. As long as you don't connect to the other graphs you could hook it up but I don't think it'll matter.

You probably already are aware of this, but if you were to network the 522 with the other two units that are already networked, you definitely don't want to power the 522 NEMA wires since the NEMA power is already being picked up by either your 38 or 520.

Dan,

Yeah, that makes sense. Thanks for the reply.
