Thanks Erik,
For such a prompt and quick reply. as always anyone attempting RS-485 without reading "ten ways to bulletproof RS485" first is making trouble for himself it can be found under 'best serial appnotes' in <--- links By the way, that is the first thing I do, lots and lots of downloading, including the above, I think I have printed out more than 500 pages of stuff on RS485. Ironically, the more you download, the more confusing it gets... Regards, John. |
