Q: Serial on Edimax BR-6216Mg

Hi All!

Are you can help me to find the Serial port on BR-6216Mg?
This is my first experience...

I found 2 jumpers JP1 (with connectors) and JP2

JP1 [4][3][2][1] (3 - ground)

JP2 [6][5][4][3][2][1] (2 - ground)

Which of them is Serial? And where is TX and RX pin?

Thank you.

Re: Q: Serial on Edimax BR-6216Mg

Hi

It's difficult to say which one could be. Both of them have enough pins to be a possible alternative. In my BR-6114Wg the connector had 5 or 6 pins (not sure). Probably JP2 if they follow that standard. You should expect the following signals:

- TX
- RX
- GND
- VCC (3.3V)

When you're done figuring out which is GND and which is VCC, i followed a simple yet effective rule: TX has some voltage relative to ground, while RX has zero volts.

Hope this helps you

Hi

I had a look at your pictures and found this page
http://wiki.openwrt.org/OpenWrtDocs/Har … com/WL-153
From the info there, the serial port should be JP1 and JTAG should be JP2.
It should look like this:

JP1 [4][3][2][1]  --> [RX][GND][TX][VCC]

I hope this helps a bit...


Nothing is impossible....except that the state of your mind makes it so.

Thank you.

The [vcc] and [gnd] you can find with multimeter (V), it's very simple.
Also [gnd] usually connected to the board base with (X) contacts.
The [tx] usually connected directly to the chip, and it also can be find with multimeter (Beep).

Also to find [tx] and [rx] you can use oscillograph.

P.S.
Do not forget about RS-232 converter (+3V to +-12V)
