XBEE Regulated Explorer Board serial interface problems

Wireless & IoT

Hi there I am using a xbee 900 pro with a XBee Explorer Regulated… I am trying to wire in a rs232 plug and am not getting any communication… I have read the forums and think everything is soldered correctly but something is still wrong. This is the schematic I have used: http://www.arduino.cc/playground/upload … pinout.gif. I have made 2 different versions with the following connections:

1: VCC, GND, DIN, DOUT (wired directly to rs232 plug based on that schematic)

2: VCC, GND, DIN, DOUT, RTS, CTS, DTR (also wired based on that schematic)

The +5v VCC and GND are supplied via a usb plug

When I plug them in, my computer does not recognize the com port (ie the device manager does not update)

Any advice?

Thanks in advance

NO, NO, NO, NO.

The XBee’s data lines are 3.3V logic----RS-232 is -12V to +12V.

The XBee Explorer Regulated board is for interface an XBee to a 5V logic processor NOT RS232.

Look up the RS-232 specs!!!

You need an RS-232 level translator between the XBee (or and uController) and RS-232. The MAX232 or MAX 3232 ICs are very commonly used. Also look at the schematic for any of Sparkfun’s boards that have a processor with RS232 port.

Hope your XBees survived but there is a good possibility that the XBees UART pins are blown.

Alright, I think I have it from here, thanks for clarifying.
