Device master RTS 1-port DB9

Key Features:

The 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.

• No serial cable distance limitations enables communication between a host PC and serial devices located anywhere across an Ethernet network
• RS-232/422/485 software selectable
• Supports native COM, TTY, or TCP/IP Socket communication modes
• Web-based configuration makes setup and management changes quick and easy
• Rugged stainless steel housing enables DIN rail or panel mounting
• Temperature rated for extreme conditions (-37° to 74°C)
• PortVision® DX remote monitoring and management software
• Software Developer Kit available for users interested in writing custom applications to run on the DeviceMaster platform
• NEMA TS2 Certified
• RoHS2 compliant under CE
• IPV6 support
