(...) Hi all, the physical connection of NXTs via RS485 is just the first half of the solution... Remeber, at 2-wire RS485 you can have one master only and up to 31 slaves. To address each slave, you need to implement a special protocol which (...) (16 years ago, 5-Jan-08, to lugnet.robotics.nxt)

Hi Ross, (...) it should be possible to use RS-485 as a bus, i.e. connect several NXTs with one cable. You need to make the cable yourself, though, and you may need some termination on the ends. Jürgen (16 years ago, 4-Jan-08, to lugnet.robotics.nxt)

(...) Thanks John. I agree that from the electrical point of view, just connecting one port 4 to another port 4 should just work with no hardware other than the cable (for short lengths, like the cables that come with the NXT). For longer cables, a (...) (16 years ago, 5-Jan-08, to lugnet.robotics.nxt)
