Low profile - low cost networking solution with minimal or no hardware.
To summarise :
- connect up to 256 Arduino's in a (ring) network
- meant for dispatching commands and status messages at a "low" rate (e.g. home automation, 10 - 100 messages/s)
- works with normal Arduino's and should work (not verified) with Mega on all 4 ports (concurrently ?)
Although I did my best to make this as easy as possible (only initialisation, transmit and receive commands), this is probably not for the "faint of heart".
So I suggest :
- try to get a single Arduino example running (bridging RX and TX as required) to get a feel of the protocol
- try the NodeX 3 Arduino example (can be changed to 2 Arduino's)
- and, to put it (im)polite RTFM
Electrically (when connecting multiple bare Arduino's), make sure to connect RX, TX and ground on all (e.g. for NodeX example with 3 Arduino : TX1 to RX2, TX2 to RX3, TX3 to RX1 and GND1 to GND2 to GND3 for respectively Arduino 1, 2 and 3).

ps.: the NodeX example might shed some more light on the intended use
pps.: the Timing example holds some (my) measurement data on throughput
