Do we need to install RS485 card when using NI USB-485?

Hi everyone,

Just a quick question. I use a NI USB-485 adapter to connect RS485 to the computer USB port. Do I still need install things like RS485 card reader?

Thanks

Zheng

I don't know what you mean by a card reader. You need to install the drivers - NI-Serial and NI-VISA.

What I mean is: usually for RS485, people use a PCI card reader; but in our case, we use NI USB-485 adapter. I am not sure if this adapter always works well for every RS485-based meters.

Thanks

I don't agree that ' usually' people use a pci card. Pci slots are disappearing and of course you don't have any with a laptop. RS-485 is RS-485 so use the USB version with confidence.
