The Comtrol DeviceMaster RTS 4-Port DB9 is a four-port device server designed for network-enabling serial communications devices. When used with the included NS-Link driver software and a host PC the DeviceMaster RTS 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.
