serial TTL pins on Bullet boards ?

Hi,

I've spotted that NS/NS-Loco products have serial communication pins available on their
boards. .
Does happen the same with Bullet series boards ? (any schematic link ?)

thanks in advance!

Ubiquiti doesn't provide any schematics.

Why not pop one open and let us know
what can be hacked? Dave

Hello,

The pins are labeled on the PCB.

Thanks,

Dimis, do you know how to connect to
those pins? You do know they are TTL? Dave

Hello,

Yes you will need to get a TTL converter (i prefer the MAX232RS)

Re: serial TTL pins on Bullet boards ?

If they haven't changed the order of the pins, here's a picture with labels:
www.ubnt.com/wiki/FileMan TongueicoStation2_-_RS232_Pinout.jpg
Pin 1 3.3V
Pin 2 Sin
Pin 3 Sout
Pin 4 Gnd
You may have to cross your fingers and experiment a bit
And a little bit on the level converter hookup you should be using:

Set a Frequency! Don't leave it on Auto!
Disable Uplink Connectivity Monitor
Always set-inform a Second time after Adopting

Only Sin, Sout, and Gnd, like in the picture:

Your converter is not powered by the Pico...

Re: serial TTL pins on Bullet boards ?

hi Flipper:

I've tried to use the TTL port,

but it seems the system won't be able to boot.(stuck at the Booting procedure)

Have you ever met this problem b4?

 

Best,

Jacky
