This innovative device offers a simple way to utilize serial devices using an available USB port, and stores settings that are unique to the connected device in nonvolatile memory (COM Port Retention), allowing you to retain the desired settings - even in the event that the adapter is connected to a different USB Port.


A cost-effective solution, ICUSB2321X is ideal for connecting a serial modem, barcode scanner, PDA or any other device with serial sync to a host computer USB port, saving the expense of having to upgrade the peripheral device to USB compliance.
