Topic: Meraki MR16

The content of this topic has been archived on 31 Mar 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I've opened the case on my MR16, and I'm trying to get connected to it via a USB-to-Serial adapter using PuTTY.  I've connected the following pins on JP1:
P1 (square solder) - none
P2 - pin 2 on DB9
P3 - pin 3 on DB9
P4 (round solder) - pin 5 on DB9

I have set my baud rate to 115200, 8 data bits, 1 stop bit, no flow control or parity.

At this time, I'm getting garbage output on my serial session when I boot up the MR16, so I can tell that there's data flowing across the cabling but I'm running out of ideas on what else I could be doing wrong.  Anyone offer any help on this matter?

That looks like a RS232 adapter. Most routers requires 0 and 3.3 volt signal levels.

Aha. I'll be picking this up then. Thanks for the help! I'll report back on Monday if this resolved my problem.

Thanks!

Did you have any luck with this?  I'm stuck in the exact same spot as yourself.

You need a MAX3232 level converter chip or board between the MR16 and the 9 pin connector.

The discussion might have continued from here.
