DeviceMaster links serial communication devices into existing Ethernet networks for remote diagnostics, management and data collection. With a low-profile design, 16 serial ports and Windows and Linux driver software, it is suitable for network-enabling bar code scanners, weigh scales, card readers and POS equipment. For existing systems, DeviceMaster uses serial port wiring compatible with widely deployed device server models. This compatibility results in a cost-effective replacement for legacy systems while maintaining investment in existing cabling and infrastructure.
