The programmable LINX III data collection and control terminals are cost-effective, rugged computers designed to collect critical data at its source. They have on-board processors and expandable non-volatile memory, which allow them to be configured and programmed to accommodate a wide variety of applications that demand error-free RS-232/485 serial network performance and connectivity. LINX III Provides Complete Control of Communications and Network Operations A powerful multitasking operating system performs host computer communications and host-independent network operation without using costly, dedicated devices such as hardware multiplexors, controllers, or concentrators. They can be managed and controlled from a central computer host using LINX's TopSail for Windows software.
