Introduction Thank you for purchasing a StarTech.com Ethernet Remote Serial interface converter. With this one, two, or four port converter, your RS-232 serial devices can be placed anywhere on your Ethernet WAN/LAN and still perform as if they were right beside you.
Hardware Installation 1. Plug the power adapter into the Power port on the converter and plug the other end into an available power source. The red Power LED onthe converter should now be illuminated. 2. Connect the converter to your network by doing one of the following: •...
Configuring the Network Settings The IP Extender Manager software displays information in a format similar to Windows Explorer. Any NETRS232 devices on your network are displayed in the “IP Extenders Near Me” branch of the “My IP Extender Network” tree. Each NETRS232 device on your network will need a unique IP address.
Configuring Network Settings Using a Web Browser The NETRS232 converter contains an embedded web server that allows you to configure your device’s network settings through your web browser. To configure an NETRS232’s network settings using a web browser, open your web browser and enter the device’s IP address in the browser’s address bar.

6. Configure the device. The following network and port settings for the device can be configured in a Telnet session: Device settings (for the interface converter device): • IP address • Net mask • Gateway • NetBios name (Device Name) •...
Activating and Deactivating NETRS232 Ports NETRS232 ports that have been detected as existing on the network are not initially activated for your PC. To access a serial port, you must first activate it. You can activate a port on one computer, some computers, all computers, or none of the computers on your network.

There are two icons that depict the state of the NETRS232_x ports and devices: Icon with green square: Icon: Under “My Computer, ” this icon Device available on the network. means the port is available. Icon with red X: Under “My IP Extender Device not available on the network.
Advanced Settings Ports that have been activated on your PC can generally be used without any further configuration. There are, however, additional configuration options available through the IP Extender Manager. Port Modes The interface converter converts serial port data to and from TCP/IP packets over Ethernet.
Virtual port (driver) settings The virtual port allows a serial port on an NETRS232 device to be used in same manner as a local serial port when the port is configured in Windows Mode (described above). In this state, the driver for the virtual port converts local serial port accesses into TCP/ IP packets to be exchanged with NETRS232 port.

To prevent this difficulty, NETRS232 Links have a “discovery” mode that allows the correct NETRS232 Link port to be found even when the IP address of the associated box has changed. To use this discovery mode, a “port binding” must be created for that virtual port.
Binding to IP Address The IP address of a network device is assigned by either the system administrator or through a DHCP server. Binding a virtual port to an IP address will force that virtual port to attempt a connection to any device with that particular IP address only.
WAN Activation Activating and accessing the virtual serial port on a NETRS232 device across a WAN can be done in two different ways, depending on how the NETRS232 device is accessible. • NETRS232 device is accessible externally – is directly accessible on the Internet. •...

4. Ensure that the port(s) to use WAN activation on are configured for “Driver Mode”. 5. Record the TCP port number of the port(s) to be accessible. 6. With the IP address and TCP port number(s) of the NETRS232 device in mind, enable port forwarding on your gateway/router for each port to be made remotely accessible.
