Hello everybody!

I have a problem with data transfer at Norte with the 820 controller.
We’ve changed to the mobile solution of a notebook.
Since then data transfer has worked only from the machine to the notebook (download). With the old computer it works in both directions.
The error #28 ring buffer overflow V24 occurs after the start of upload.

Preset values:

Baudrate : 9600
Data Bits : 7
Stop bits : 1
Parity : even
Flow Control : XON/XOFF

Thanks in advance!

Hello!
I’ve had the same problem with a new computer.
Reduce baud rate to 2000. If many programs work, then the error occurs.

Hello,
Thanks for you suggestion!
Unfortunately I don’t have bit settings for another baud rate at the machine. It isn’t a problem at the PC, but the values have to be the same at both sides.

Allocation RTS-LINE
Should it be 5018-5020 or am I wrong?
Our manual suggests only 9600.

Hello!

I know it only for the 810 controller. It’s 5019 and 5021 there.

The baud rate for 2400 would be 0101
And for 1200 = 0100

Maybe it helps.

P.S. RTS-Line?
You have to use either Xon/Xoff or RTS/CTS, but not a mix of both of them!

5019 and 5021 is right.
But your problem is that you use DOS-Software with windows XP.
Suggestion:
1. Reduce baud rate
2. Boot DOS
3. Use Windows-program. It works even with HyperTerminal.

Thanks for your help!

@ Meister

Controller has RTS-LINE, program - XON/XOFF.
But it works.

@ HaDi

I’ve tried thta with 4800 and 2400, but it doesn’t work 100%.
I took a look at the settings of NC-linc and found "LINE DELAY". It stands at 50 milliseconds and it works with baud rate 9600.

Thanks for your help once again!
