Hi,

I stand corrected.

The 302 manual (pg 25) says pin 4 of the RJ11 is
"+5V = Device power – fuse-limited to 0.9 Amp"

pin 6 and 8 of the DB-9 connector are
"+5 volt power from 302 to connected device; fuse-limited to 0.9 Amp"

I've used the DB-9 connector on my 302 to provide +5V power to an iPAQ for
7 years now. Cambridge and others have sold connectors for that purpose
for a long time. I also have a 303 hooked up to the RJ11 plug.

Manual is available at the Cambridge website.

Hi Dan,

That is a very bad idea! The RJ connector on the back of the 302 is for
connection to the 303 LCD display. The 303 is a low voltage device. Your
Mio is not. I'm not certain, but I fear you will fry something in the
302.

Best Regards,

While I had my panel apart the other day, I noticed the RJ jack in the
back of the 302. Since I had half a Cambridge cable, I plugged it in,
powered up, and measured voltage across the red and black leads - 5v!

I took a standard USB cable that fits the Mio, cut it, and measured
the red and black leads - again, 5v! Tomorrow, I'll connect the two
cables together and run the Mio of the ship's batteries.
