Serial port not shown in MAX

[grimmy123]

In my case this is not consistent, some times NI RS485 USB cable is not detected as I posted earlier.

Is there any solutions for that? I ensured that my device manager is up and running, and it was.

Also to add up, I stated my PXI system this morning and there was nothing fishy with the startup programs or system connection.

Today when I was running the application the USB 485 port lost it's reference and I have to unplug and plug it back again?

I need to fix this, because the production might not like this behaviour.

Hello @grimmy123,

I think at this point since the original issue of 'serial port not shown' has been resolved, and now you are finding your serial port then losing your serial port, you will get more exposure to the rest of the NI community if you start a new thread under the title 'Serial Port Disappearing.' I would recommend starting a new thread in order to get more exposure to this issue to get it resolved in the most timely manner.

I might recommend resetting your MAX database to reconfigure your serial port, but again, you will get more exposure if you create a new thread:
