The ADAM-4561 allows PC users to connect their serial devices to systems that use USB interface. To attach the ADAM-4561 to a PC, you never need to open the chassis or power down your PC to install the hub. This provides one extra high-speed RS-232/422/485 port. The power is derived from the USB port, so there are no power adapters to deal with. This makes ADAM-4561 especially suited for modems, printers, POS systems and industrial control devices.
