No correction required

I have not seen that documented either - very interesting reading, as you suggest, Paul would seem to be the ideal person to comment,

Hi Mark, Aah, OK, thanks - I see. As you say, there's a lot more to designing an RS232 link than one might first think - cable considerations alone is a topic in itself. Although we can speculate and could even design a modern day serial port to coax interface that would probably work better than th...

Hi Mark, I agree with what you say about cable length vs. baud rate, I should have put the 9600 baud at 15m on the web page, but as Node is running at 9600, then the accepted norm of 15m is applicable in this case (without line drivers). As I intimated, the limiting factor is cable quality, the real...

Hi Mark,

no more actual testing done, I have been spending a bit of time trying to understand how the card works. Your previous post helped and with a bit of "googling" and more reading of the datasheet, I'm getting there

For discussion . . . . . . Recently, I have been trying to get a Node system running, unfortunately, the ROMs that I am trying to use have a problem and won't let the MTX boot. However, as part of the effort to get a ring running, I have tried to work out how the nodes should be physically connected...

Well done !

That looks like a really good design, wherever did you find it?

Interesting !

It looks like you're putting DC out?

Hi Martin, results as shown - perhaps you meant a blue A on a white background? (It is the foreground attribute that seems to be playing up.) The Attribute reads all read "6" for the higher numbers (>20), so the code changed as shown to fit the frist 20 reads on the screen. You won't see m...
