Enclosures, Cabling & Connectors
The ADAM-4561 allows PC users to connect a serial device to systems that use an USB interface. To attach the ADAM-4561 to a PC, there is no need to open the chassis or power down the PC. One or two extra high-speed RS232/422/485 ports can be had instantly. The power is derived from the USB port, so there are no power adapters to deal with. This makes the ADAM-4561 especially suited for modems, printers. POS systems and industrial control devices.
Compliant with USB v1.1, the ADAM-4561 features several powerful functions such as high-speed 115.2 Kbps transmission, support for various O.S., independent RS232/422/485 ports, etc. By simply plugging in a USB hub, the ADAM-4561 eliminates the configuration issues associated with high-priced, older card solutions. One only has to install the drivers, no need to set cards, IRQ addresses, DMA channels, or device addresses. This reduces a lot of programming effort.
USB, now standard on all new PCs, offers significant advantages over earlier bus types. A single USB interface can connect up to 127 devices at data rates up to 12 Mbps. This kind of easy and convenient connectivity means that networks can grow with users' requirements.
