Sorry to jump in on this topic.
I'm currently on the look out for a RF product from Xbee that can transmit modbus rs485, spec pretty much identical to Sams post above.
Over the last 2 weeks i have been passed around the Xbee organisation, America, France, India, Australia. and no body has given me clear feedback on what product to choose.
Last week one technician from Australia contradicted technical advice from another technician from India. Safe to say my head exploded with confusion.
I'm really hoping someone on here can help point me in the right path.
Ideally i'm chasing the module only device, Bare bones, no enclosure, so that rules out the Digi Xbee RF modem.
The product would be great if it was out of the box, meaning minimal configuration is fine, coding would be an issue.
I was liking the Xbee 900HP pro. but only just found out that it cannot transmit modbus on its own, i'm told it requires a MCU to convert the modbus to Uart ? ?
Reading this post you talked about the Xtend. is this a possibility.I looked up the Xtend and there has been some little talk of modbus affiliated with it.
I'm drawing blanks with this guys. I cannot believe that Digi as big as it is cannot actually provide technical support on its products.
Any help would be so so so appreciated.
Thanks in advance
