Xbee to Rs232

0 votes
Hi,
I want to connect my xbee (1mw 802.15.4) module to PC to receive data wirelessly from the co-ordinator xbee that transmits data.


Xbee outputs 3.3v @45mA and how do i connect it to max 232 to connect to PC? It requires 5v data ip. How can I connect my xbee to PC thro RS232. What other ways than max232? What ways to convert 3.3v to rs232 logic.

Thanks.

You can download the schematic for the RS-232 development board from the Digi web site. That has the circuitry you need, and to the best of my belief Digi are happy for people to make use of it.

I'm sure you could find ways other than MAX232, though that seems to be the convenient solution that most people go for.

Your first post mentions that the PC requires 5V data input. I'm assuming that it's a standard PC with RS-232 levels. If it really does want 5V, then a different level shifting circuit would be needed.

you also can use voltage regulator to give you 3.3V from 5V....

Hi thanks, for the kind reply.

I actually meant that the Tx and Rx input to Max232 require 5V, which it converts to the RS-232 standard to communicate with PC.

Sorry for the unclear wordings.

And can I use the same RS232 development board for both firmware updating and for communication of the received data from xbee to PC.

If am silly, sorry. Am new to this.

Thank-you.

ANd

Connecting the xbee to my microcontroller, 8051 with internal UART,
IS IT ENOUGH THAT I CONNECT THE DOUT pin (Xbee) to RX(of 8051) & DIN to TX?
what else sholud I do to setup connection between 8051 and xbee.

Thank-you.

Here's a hint bro
Google voltage level shifters

Also, in d datasheet, search for "minimum pins to connect to flash firmware"

Look at the development board schematic sheet as well

Yes, the RS232 development board works great for both of those purposes. You can download and use the X-CTU tool to perform firmware upgrades and configuration , and it even has terminal functionality so that you can see your data in it before you write your application to talk to the XBee yourself.
