How to use VISA + USB001 instead of COM1

[Pierre_F]

hello

I need to communicate programmatically to a printer that was first installed via COM1 RS232 and configured with VISA functions

(document joined, LV2012, sorry for the old bad code)

now it's not working anymore and I would like to use the USB input instead. in the printer properties, the printer is defined as USB006

When I change my VISA initialisation node from COM1 to USB006? if not is there another way?

regards

You could try communicating with it using USB RAW mode.  However, a lot of devices use different communication over USB than they do serial, so the chances that this will work aren't super great.

Hi Pierre,

Why don't you replace the PC COM port by a simple USB-to-RS232 converter? They are cheap (in the order of ~10€)…

I will try the converter and keep you informed

thanks
