Pinout Diagram
The Comtrol DeviceMaster RTS 1-Port VDC DB9 is a single-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. DeviceMaster RTS VDC products are designed specifically for use where an existing power source from 5-30 VDC will be used. This product is fully compliant with the European RoHS Directive 2002/95/EC.
