I haven't posted here in a while, my RCXs having been on a hiatus. Well, after breaking them out again, I discovered that I had foolishly left alkaline batteries in some of them and of course some of the batteries had started to leak. This caused (...) (17 years ago, 9-Jan-08, to lugnet.robotics)

(...) 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 (...) (17 years ago, 5-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 (...) (17 years ago, 5-Jan-08, to lugnet.robotics.nxt)
