Ordering Information
This compact device quickly converts USB port connections to RS-422/485 so you can connect legacy serial devices to a newer PC or laptop. Continue to use legacy commercial and industrial RS-422/485 devices without making any changes to the applications written for them.

Plus, because it features 2000-volt optical isolation, you can protect your PC and other equipment from dangerous spikes and surges on the RS-485/RS-422 network.
