Frequently Asked Questions - NETRS2322P StarTech.com

How do I connect the NETRS2322P to my network?

Connect the RJ45 Ethernet port to your network switch or router using a standard Cat5e/6 cable. Then power the device via USB or the included 5V adapter. The device will obtain an IP address via DHCP by default.

Can I use this server with a virtual COM port on Windows?

Yes, the NETRS2322P supports virtual COM port (VCP) drivers. Download and install the appropriate driver from StarTech.com's support page, then configure the serial port settings in the device's web interface to match your application.

What is the maximum baud rate supported?

The NETRS2322P supports a baud rate range from 300 bps up to 230.4 kbps. Ensure your serial device also supports the chosen rate for proper communication.

How do I reset the device to factory defaults?

Locate the reset button on the device (usually a pinhole). Press and hold it for about 10 seconds while the device is powered on. The LEDs will blink to confirm reset. After release, the server will reboot with default settings.

Can I mount this device on a DIN rail?

The NETRS2322P does not include a DIN rail clip by default. However, you can purchase a separate DIN rail mounting kit compatible with StarTech.com serial servers if needed.

What operating systems are compatible?

The NETRS2322P is compatible with Windows (7/8/10/11), Linux (with or without built-in drivers), and macOS. For optimal performance, use the latest drivers from the StarTech.com website.

How can I check if the device is working?

After powering up, observe the Power LED (should be solid green) and the Ethernet LED (should blink if link is established). Try pinging the device’s IP address from your computer. If successful, you can access the web interface via a browser.

What is the default IP address?

The default IP address is 192.168.0.100, assuming a DHCP server is not present on the network. If DHCP is available, the device will obtain an automatic IP. You can find it using the included utility software or by checking your router's DHCP client list.

Can I use the device in a daisy-chain configuration?

No, the NETRS2322P is a single-port server (or two-port, each acting independently) and does not support daisy-chaining. Each serial port connects directly to a serial device.

What should I do if the serial port is not communicating?

First, verify that the baud rate, data bits, parity, and stop bits match between the server and the serial device. Check cable connections (straight-through vs. null modem). Use a terminal program to test. Also ensure no IP conflicts or firewall blocking the port.

Install the device server

The device server can be powered using the provided power adapter, or using the terminal block power input (9\~36V DC). You can also use redundant power input by connecting both the power adapter and terminal block power.

If one of your power sources fails, the device server will switch to the secondary power source.

Install the device server using the power adapter

1. Turn off any equipment that will be connected to the device server.
2. Connect up to two RS232 serial devices to the device server's DB9 RS232 ports, using a straight-through serial cable (not provided).
3. Connect your network equipment to the device server's 10/100Mbps RJ45 port, using RJ45 Cat5e (or higher) Ethernet cable (not provided).
4. Select the appropriate power clip for your region and connect it to the power adapter.
5. Connect the power adapter to an AC electrical outlet and to the device server's DC power input port. The Status LED (power) will light up solid (green), and the device server will beep once.
6. Turn any equipment that was turned off in step 1 back on (networking and serial devices).

Install the device server using the terminal block

1. Repeat steps 1 through 3 from the Install using the power adapter section.
2. If already inserted, remove the terminal block connector from the device server. The two screws located on the left and right side of the terminal block connector may need to be loosened using a small, flat-head screwdriver (not provided).
3. Loosen the two screws on the top of the terminal block connector using a small, flat-head screwdriver.
4. Connect the positive and negative wires from your DC power source to the proper terminal block connectors and tighten the screws. The terminals are marked on the device server's casing.

Note: Ensure that the polarity of the input power — positive (+) and negative (-) — is correctly matched with the terminal block pins to ensure proper function.

1. Reinsert the terminal block into the device server and tighten the screws that were loosened in step 2. The Status LED (power) will light up solid (green), and the device server will beep once.

Configure the device server

You can configure the device server by using the EMT Connection Wizard software or by using a web browser to access the GUI (Graphical User Interface).

Install and configure the EMT Connection Wizard (Windows only)

1. To download the latest software, use a web browser and navigate to http://www.startech.com/NETRS2322P.
2. Click the Support tab.
3. Download the software.
4. When the download is complete, extract the contents of the compressed file(s) that you downloaded.

Note: Alternatively, you may use the provided software CD to install the software. However, it is highly recommended that you download the latest software from the StarTech.com website.

1. Double-click the appropriate software .exe file for the version of Windows that you're running. For 64-bit operating systems, run the file in the x64 folder. For 32-bit operating systems, run the file in the x86 folder.

2. Follow the on-screen instructions to complete the installation.

Note: You may be asked to restart your computer to complete the installation.

1. Once installed, launch the EMT Connection Wizard by selecting the icon on your Windows desktop or Start menu.

2. Follow the on-screen instructions to configure the device server and your connected serial device(s).

Use the EMT software

Before using the EMT software, ensure the device server and your computer are on the same network.

1. Once the software is installed, launch the EMT Connection Wizard by selecting the icon on your Windows desktop or Start menu.
2. Click the Elevate button to run the wizard in Administrator mode, then click Next.
3. Select the kind of link you want to create. The type of link you want to create depends entirely on the application you are using the device server for. In most cases you should select the first option, Create a link between a Virtual Serial Port and a Device.
4. Create a new VSP (Virtual Serial Port) by selecting the Create new VSP option, then select a port name (for example, COM1). Then click Next.

5. Click Select from the list. The device server should show in the Auto-Discovery list. Double click it to select it.

6. On the following screen, click Next.

7. Select a Channel and click Next. Channel 1 is for the device server's serial port 1, Channel 2 is for the device server's serial port 2.
8. Select which side will need to send the data first (for example, setting the device server as a client or as a host). Click Next.
9. Continue to follow the on-screen instructions, entering any further settings (for example, gateway and netmask settings, serial settings, and so on) that are referenced. Click Next to navigate to the next screen.
10. Click Configure, then click Finish.

Notes:

• You can use the EMT DS Manager to manage settings without having to use the web interface and to make sure that the computer can see the device server on the network.
• The EMT DS Manager software is used for configuration of the device server itself, while the VSP Manager can be used for configuration of the serial port(s).

Configure using the web GUI (Windows, Mac, and Linux)

1. Use a web browser, and type the following in the address bar: http://192.168.1.40
   Note: You must be on the same subnet (192.168.1.xxx) in order to use the address referenced in step #1. If you are having problems connecting to the device, check your network infrastructure to ensure the device server is on the same subnet.
2. Leave the password field blank, and then click Login.
3. Set up and customize the device server's settings as needed.

Web GUI Defaults:

Default IP: 192.168.1.40
