Comtrol DeviceMaster RTS 32-Port RJ45

Key Features:

Comtrol Device master RTS 32-Port RJ45 Rack Mount is a 32 port device server designed to enable placing serial devices on Ethernet network especially in applications where connecting legacy devices to pc is required without software change.
A pair of DeviceMaster RTS units 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
• RS-232/422/485 software selectable
• Native COM, TTY, or TCP/IP socket communication modes
• Provides 32 serial ports in a 1U rack mount space
• 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
• Rugged metal housing enables rack mounting
• Wide operating temperature (-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
• SSL & SSH management, SSL serial data stream encryption
• RoHS2 compliance under CE
• IPv6 support
