DeviceMaster RTS 4-Port RJ45

Key Features:

The DeviceMaster RTS 4-Port RJ45 is an eight-port device server designed to enable serial devices to be placed anywhere on the Ethernet. The DeviceMaster RTS 4-Port RJ45 is used in applications where connecting legacy serial devices to a PC without software changes is a requirement
A pair of device master RTS can be used to create a point-to-point serial tunnel across the network that seamlessly transfers serial data via TCP or UDP socket connections.

• 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
• Temperature rated for extreme conditions (-37° to 74°C)
• Rugged stainless steel housing enables DIN rail or panel mounting
• PortVision® DX monitoring and management software automatically monitors devices on the network and enables user to view status, update firmware and resolve issues remotely
• Software developer kit available for users interested in writing custom applications to run on the DeviceMaster platform
• NEMA TS2 compliant
• RoHS2 compliant under CE
• IPV6 support
