I tried usb:/dev/ttyUSB0 and usb:ttyUSB0 and same result.
No. I mean a direct USB cable - no RS-2332 anything. Just pure USB.
And then specify usb: for the device (nothing after the colon).
I've attached a photo how the connection looks like. I've got only
the RS-232 cable bundled. I have no clue, where I could get a direct
USB cable. If You know by chance, let me know please.
hello mr Jakub.
i think you have the same baum display as one of mine.
I would like to try to help you, and for that I need to learn a
couple of things.
1. Are you using the original COM cable that came with the display
from the factory?
it looks like a flat wire with two female plugs on the ends.
I'm not quite sure, whether it's the original cable, since I bought
everything in used condition. It has a female rectangular plug with 10
pins for the Vario and an RS-232 9 pin for the PC on the other end.
it is very important to use the original wire as its pinout differs
from the usual internal pinout of the rs232 connector. several of
these wires were made for me.
If You have the pin layout, I could check, if it's correct, and
eventually solder it myself correctly. If this would be the solution,
I'll be very happy!
2. have you checked the two connection pins? they are equivalent, but
I managed to burn one on one of my displays.
You mean the connection ports? There are two and both have same
symptoms. No reaction.
you should also be careful with your com to usb converter.
for me, one of these broke after a week of use.
I'll be happy to get it running through a regular RS-232 port on a
commodity PC. I've bought the USB connector, because the seller
claimed, that it would work with that.
for a start, look either in the kernel logs, or in / dev /, or better
both whether the adapter is detected when connected.
and specify the path to its device in brltty.conf. most likely it
will be / dev / ttys0-usb
Yes, the adapter is connected as / dev / ttyUSB0 and configured so.
Yet, same symptoms. No reaction.
I'd be really happy about the pin layout of the original serial
connector.
Thanks so much,
hello Jakub. sorry for the long silence.
I asked the person who made the wire for me, he said that there is a
usual rs232 pinout.
so it turns out that I was wrong.
Jakub
