visa config. problem

[Patrick0418]

Hi, everyone

I connect my device at COM1, but I cannot find that com port in serial config.

It means I cannot find any connection with my device in system manager.

I only want to use labview to control my device, even not use dll.

Anybody can figure out what problems in my situation ?

# I use vb.net to do the same thing, and it works. So I think my deivce have no problems.

What exactly to you mean?

Does com1 show up in Windows Device manager?  Does com1 show up in Measurement and Automation Explorer?

You are going to see anything more than that.  Nothing about either thing will tell you anything about what may or may not be connected to the serial port.

Hi, RavensFan

Com1 shows in windows device manager, but it not show my device name.

Like this picture.

So visa resource name not show "Com1".

I didn't install MAX, and I will try later and reinstall my visa driver.

thank for your reply.

Does the VISA control show ASRL1:  or something like that?   Does it show any of the other com ports such as 2 or 4?

Definitely reinstall the VISA drivers.
