XBee to RS-485

Post by dbrouwer »

I want to build as simple a board as possible to connect an XBee module to an RS-485 device. I've done a bit of experimenting around using a NOR gate and an RS-485 transceiver, and utilizing the TXD, RXD and RTS pins of the XBee, but with traffic coming over the XBee network I'm not seeing the RTS pin toggle, and the RS-485 device doesn't respond.

Any thoughts or ideas on this will be appreciated.

I thought I might use the Adafruit XBee adapter kit as the basis for connecting an Xbee module to an RS-485 device. What else will I need, and how do I connect things up?

Thanks

Doug
