ZigBee vs. 6LoWPAN
It seems that you're describing a tree topology network so RUM may be an option indeed, especially if your nodes do not require sleeping capabilities. Quote: IMO, 6LoWPAN hasn't...

RS422 standard connector?
Actually there is supposed to be a "industry standard" pinout for RS422/485 DB9 connectors, you may find the pinout at the datasheet of the FTDI USB to RS422 converter modules,...

RUM: timer problem
OK, so what you need to do is to disable sleeping when a request is sent by the coordinator so you'll have enough time to get your sensor readings and send them. When you receive...
