Power supply for the reach RS2

Ah, so I can use the serial port to provide power OR to receive data, BUT NOT BOTH. That’s not very clear from the documentation.

Actually, this whole issue could be much better documented.

There’s a response from Emlid in this thread: RS2 external power - #4 by noel

The response says: " To charge the receiver 5 watts is required. For operating 7,5 watts on average is required (10 watts maximum)."

12V at 15A is 180 Watts. Is it safe to provide 180 Watts? If so, what does “10W maximum mean?”

Obviously I don’t want to spend more on electricity than i need to, so I need to understand the ideal working supply specification.

DB9 is a data-transport connector

Is it wired as standard RS/232? If I run the RS2 from a battery and connect the DB9 cable to a serial port on a PC, will the PC be able to pick up the data? That would be useful to know.

Usually, you just need to pull the ring attached to a cable

that worked. Thank you. I was wondering what that ring is for! Again, it’s not awfully clear.

Thanks for the information so far.

Regards

Simon
