DeviceMaster LT16
The DeviceMaster LT16 is a secure, compact device server for easy integration of serial communication devices into LAN, Internet, or cloud-based systems. The device 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 ideal for network-enabling barcode scanners, weigh scales, card readers, and POS equipment. For those with existing systems, the DeviceMaster LT16 uses serial port wiring compatible with widely deployed device server models from Digi International Inc.
