Comtrol's DeviceMaster PRO 10/100Base-T device server provides bus-independent serial port expansion, a platform for hosting and running application-specific programs, and the ability to remotely monitor and manage serial devices. Providing support for Linux and Microsoft Windows environments, it delivers quick and easy peripheral connectivity utilizing the Ethernet LAN. The DeviceMaster PRO also supports RS-232/422/485 software-selectable interfaces on each DB9 or RJ45 port and is ideally suited for applications where multiple interface formats are required to connect peripherals that are located long distances from the server and when programmability and enhanced surge protection is desired. Serial ports can reside outside the server anywhere on the LAN - so the server can be kept in a secure back-office location while serial devices conveniently reside anywhere they are needed! To address the needs of customers installing device servers in harsh conditions such as electrically noisy industrial, factory, and retail environments, the DeviceMaster PRO delivers enhanced surge protection of 25KV. This is ideal for situations involving motors, power lines, high-power equipment, and short-circuits, which are common sources of high-voltage, short-duration transient electrical currents that can lead to the failure of equipment lacking proper over-voltage protection. DeviceMaster PRO provides sustained, reliable operation under electrically noisy conditions to help keep your mission-critical systems running smoothly. When you have multiple device servers installed, Comtrol's PortVision port management software enables efficient configuring, monitoring, and managing of multiple DeviceMasters from one centralized PC-based application, delivering a graphical, customizable, comprehensive, and powerful management interface.
