Hardware Installation

(Optional) Configure DB-9 Pin 9 Power

By default, the Serial Device Server is configured with the Ring Indicator (RI) on Pin 9 , but it can be changed to 5V DC. To change the DB9 Connector Pin 9 to 5V DC output, please follow these steps:

WARNING! Static Electricity can severely damage electronics. Ensure that you are adequately Grounded before you open the device housing or touch the change the jumper. You should wear an Anti-Static Strap or use an Anti-Static Mat when opening the housing or changing the jumper. If an Anti-Static Strap isn’t available, discharge any built-up static electricity by touching a large Grounded Metal Surface for several seconds.

1. Ensure the Power Adapter and all Peripheral Cables are disconnected from the Serial Device Server.

2. Using a Phillips Screwdriver , remove the Screws from the Housing.
   Note: Save these to re-assemble the housing after changing the jumper.

3. Using both hands, carefully open the Housing to expose the Circuit Board inside.

4. Identify Jumper #4 (JP4) , located inside the Housing next to the DB9 Connector.

5. Using a pair of fine-point tweezers or a small flat-head screwdriver, carefully move the jumper to the 5V position.

6. Re-assemble the Housing , ensuring the Housing Screw Holes align.

7. Replace the Housing Screws removed in Step 3.

(Optional) Mounting The Serial Device Server With DIN Rail

1. Align the DIN Rail Bracket with the DIN Rail Mounting Holes on the bottom of the Serial Device Server.
2. Using the included DIN Rail Mounting Screws and a Phillips Head Screwdriver , secure the DIN Rail Kit to the Serial Device Server.
3. Insert the DIN Rail Mounting Plate at an angle starting from the Top , then Push it against the DIN Rail.

(Optional) Mounting The Serial Device Server To A Wall Or Other Surface

1. Secure the Serial Device Server to the desired Mounting Surface using the appropriate Mounting Hardware (i.e., wood screws) through the Wall Mounting Bracket Holes.

Install the Serial Device Server

1. Connect the included Power Supply or a 5V~24V DC Power Source to the Serial Device Server.
   Note: The Serial Device Server can take up to 80 seconds to startup.

2. Connect an Ethernet Cable from the RJ-45 Port of the Serial Device Server to a Network Router , Switch , or Hub.

3. Connect an RS-232 Serial Device to the DB-9 Port on the Serial Device Server.

Software Installation

1. Navigate to:
   www.StarTech.com/I23-SERIAL-ETHERNET
   or
   www.StarTech.com/I43-SERIAL-ETHERNET

2. Click the Drivers/Downloads tab.

3. Under Driver(s ), download the Software Package for Windows Operating System.

4. Extract the contents of the downloaded .zip file.

5. Run the extracted executable file to start the software installation.

6. Follow the on screen prompts to complete the installation.

Operation

Note: The devices support features which secure and protect the devices and its configuration using standard/best practices but as these are intended to be used in controlled environments using proprietary software (virtual COM port) and open communication standards (Telnet, RFC2217) which do not encrypt the data they should not be exposed to an unsecure connection.

Telnet

Using Telnet to send or receive data works with any operating system or host device that supports the Telnet protocol. The software for the connected serial peripheral device may require a COM Port or mapped hardware address. To configure this, the StarTech.com Device Server Manager is required, which is only supported on Windows operating systems.

To communicate with the connected Serial Peripheral Device via Telnet, perform the following:

1. Open a terminal, command prompt, or third-party software that connects to a Telnet server.

2. Type the IP Address of the Serial Device Server.
   Note: This can be found using the StarTech.com Device Server Manager for Windows, or by viewing the connected devices on the local network router.

3. Connect to the Serial Device Server.

4. Type in the terminal, command prompt, or third-party software to send commands/data to the Serial Peripheral Device.

Use the Software to Discover the Serial Device Server

1. Launch the StarTech.com Device Server Manager.

2. Click Auto Search to initiate the process of discovering Serial Device Servers on the local network.
3. Discovered Serial Device Servers will appear in the “Remote Server(s)” list in the right pane.

4. Select “Add Selected Server” to add a specific Serial Device Server or “Add All Servers” to add all discovered Serial Device Servers.

5. The Serial Device Servers will be mounted in Device Manager as “SDS Virtual Serial Port” with an associated COM port number.

In the Software

1. Open the StarTech.com Device Server Manager.

2. Select “Configure in App” or double click the Serial Device Server in the list.

3. When the Settings Window opens, use the drop down menus to change Baud Rate, Data Bits, COM Port Number, and more.
   Note: If changing the COM Port Number, see “Changing COM Port or Baud Rate in Windows” on Page 15.

4. Select “Apply Changes” to save the settings.

In the Web Interface

1. Open a web browser.
2. Type the IP address of the Serial Device Server into the address bar.
3. Enter the password and select “Login”. See Default Password on Page 6.
4. Select the “Serial Settings” to expand the options.
5. Use the drop down menus to change Baud Rate, Data Bits, COM Port Number, and more.

6. Under “Set”, select “OK” to set the serial settings to the port.

7. Select “Save Changes” to save the settings to the Serial Device Server.

Changing COM Port or Baud Rate in Windows

To change the COM Port number or Baud Rate in Windows , the device must be deleted and re-created in the StarTech.com Device Server Manager.

Note: This is not necessary when using macOS or Linux which use Telnet to communicate with the Serial Device Server and do not map the device to a COM port or hardware address.

1. Open a web browser and navigate to the IP address of the Serial Device Server or click “Configure in Browser” in the StarTech.com Device Server Manager.

2. Enter the Serial Device Server password.

3. Under “COM No.”, change it to the desired COM Port number or change the Baud Rate to match the Baud Rate of the connected Serial Peripheral Device.
   Note: Ensure the COM port number you assign is not already in use by the system, otherwise it will cause a conflict.

4. Click Save Changes.

5. In the StarTech.com Device Server Manager, click the Serial Device Server which should still have the old COM Port number, then click Delete.

6. Re-add the Serial Device Server using “Add Selected Server” to add a specific Serial Device Server or “Add All Servers” to add all discovered Serial Device Servers.

7. The Serial Device Server should now be mapped to the new COM Port number.
