Jasper, I was trying with or without checkmarks - no luck.
I believe, they are not for COM2 but for COM1 (PLC connection).
I agree that they should be checked in order to communicate with
PLC (at least that's how it looks to me) but this should not
affect downloading of application to the touchscreen.
I didn't try to use CF card yet (I always have one on me)
but that's not the point, I have to make the RS232 connection.
About auto-deceting port settings of Protool, that's fine but
I don't like that I cannot select port settings if I want to.
For example, On the TP270 it is possible to select parity, stop bit
and handshaking while Protool doesn't have such options.
Who can convince me that this transfer didn't fail because
Protool guessed it's port settings wrong?
But I'll follow your advice and try to load the software on
another machine just to try it out.
BTW:
I see quite often that serial ports do not work with this or
that device. This is just not acceptable. I don't care if the
COM port of some laptop is saving energy. If the lower power
still meets the spec, it must work.
If some device DOESN'T work because of "low power COM port",
it is not the PC to be blamed for (or the USB<>RS232 converter).
It's the designers of the picky device that didn't do proper job.
Hacking port to obtain power (like in dreaded PIC for AB PLCs
just to name one) is just not professional design.
Dragging 6-8 year old desktop or tower PC with monitor, keyboard,
UPS and power bar is NOT what I call mobile computing.
