ADAM-4561 ModuleThe ADAM-4561 allows PC users to connect a serial device to a system that uses a USB interface. To attach the ADAM-4561 to a PC, you don’t need to open the chassis or power down your PC. Instantly get one 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 the ADAM-4561 especially suitable for modems, printers, POS systems and industrial control devices. The discerning feature of the ADAM-4561 is the galvanic isolation between the USB port and the RS-232/422/485 port. This makes the device especially suited to use in harsh industrial environments.
