Comtrol Device Master RTS VDC 1-Port DB9

Key Features:

Comtrol DeviceMaster RTS-1 port is a single-port device server designed to enable serial devices to be placed on Ethernet especially in application where connecting serial legacy devices to Ethernet network without software changes is a requirement.
The VDC version is designed specifically for use where an existing power source from 5-30 VDC will be used.

• No serial cable distance limitations enables communication between a host PC and serial devices located anywhere across an Ethernet network
• Software selectable RS-232/422/485 serial interfaces
• Supports native COM, TTY, or TCP/IP socket communication modes
• Web-based configuration makes setup and management changes quick and easy
• Real-time e-mail event notification alerts administrator of potential connection and security issues
• Wide operating temperature range (-37° to 74°C) for harsh environments
• Rugged stainless steel housing enables DIN rail or panel mounting
• Variable power input eliminates need for power converters
• PortVision® DX monitoring and management software automatically monitors devices on the network and enables user to view status, update firmware and resolve issues remotely
• RoHS2 compliance under CE
• IPv6 support
• NEMA TS2 Certified
