USB to RS-232 Opto-Isolator (SP385A-R3)
This compact opto-isolator enables you to attach an RS-232 device to a USB port and gain isolation from voltage spikes and ground loops. It doesn't require PCI or ISA slots, or IRQs. Using an optional USB Type A - Type B cable, simply plug the opto-isolator into the USB port and Windows will configure the device as an additional COM port.
USB to RS422/485 Converter with Opto-Isolation (SP390A-R3)
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.
Simply plug it into your PC's USB port using the included USB cable (0.9m), then configure its DIP switches for 2- or 4-wire operation. The converter will show up as an additional COM port in your PC's Windows Device Manager. The serial terminal block can be removed for easy wiring.
