The Comtrol DeviceMaster RTS 32-Port RJ45 Rack Mount is a device server designed for network-enabling serial communications devices. It enables placement of COM or TTY ports anywhere on an Ethernet network or across the internet. In applications where connecting legacy serial devices to a PC without software changes is a requirement, 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. The device possesses a wide operating temperature (-37° to 74°C), as well as a feature that provides an administrator with real-time e-mail notification of potential connection and security issues.
