Product ID: NETRS2322P
This 2-port serial device server is a cost-effective way to remotely connect to and manage two serial devices over your typical IP network. The device server integrates two RS232 ports into a rugged metal housing with an extended operating temperature range, so it’s perfect for factory and industrial settings.
If you’re looking for a reliable serial-over-IP control solution, then this device server can help. With a rugged metal housing and an extended operating temperature range, you can rest assured that the device server can deliver the reliable performance you need, even in harsh environments.
Plus, it features two integrated mounting brackets, so you can mount the device server to a surface or a wall as needed, for out-of-the-way installations.
With redundant power input, this dual-port serial device server ensures seamless operation, even in the event of power dips or failures. It features a wide-range, terminal block power input (9~36V DC), and includes a universal power adapter.
Because it features two power inputs, if you experience a power disruption the device server automatically switches to its secondary power source. With redundant power input, the device server remains operational if one of the power sources fails, so you can continue to connect to and manage your serial devices when needed.
This highly customizable device server is easy to configure to suit your application. For easy setup, Windows® users can use the provided Virtual COM port software, or the versatile Web-based interface.
The RS232 device server supports Telnet (an operating system independent communication protocol), so it can be integrated into mixed OS environments (Windows, Mac, Linux®). Plus, it supports VCOM, TCP, ICMP, IP, TCP, UDP, DHCP, and BOOTP protocols.
The NETRS2322P is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Before you continue, make sure that your computer can communicate with the network serial device over your network. For more information, refer to the following FAQ.
To set up your network serial device, you will need to install and configure the included software. To install the driver software, complete the following:
Note: Windows will typically save the files to the Downloads folder that is associated with your user account (for example, C:\Users\your_name\Downloads).
Note: To view your system type, click Start. Right-click Computer, and then click Properties.
To configure the software to add a virtual COM port to your computer, complete the following:
Note: If you have multiple servers in the list, you may use the Buzz! button to identify the unit. The unit that has been buzzed will blink the top red LED on the unit.
You will now be able to use the COM port(s) in your application. To test the COM port, refer to the following FAQ: https://www.startech.com/faq/serial_loopback_test_rs232_windows#NETRS2322P
In order for the serial device and your computer to communicate to each other, they both need to be on the same physical network and the same subnet.
To connect your serial device and your computer to the same physical network, plug both devices into the same router.
Typically, in order for devices to be on the same subnet, the first three numbers of the IP address must match. The fourth number of the IP address must be different, as two devices cannot have the same IP address. For example, if your computer’s IP address is 192.168.0.1, then the subnet is 192.168.0.XXX. You can replace the XXX with any number, as long as it is not currently in use by another device.
To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:
Note: To open a telnet session on the COM port, you need a telnet client like PuTTY or Hyper Terminal. Windows XP comes with Hyper Terminal.
If the loopback test fails, make sure that the serial cable or gender changer that you are using works and that the adapter is in the correct port.
You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session. When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is. Close the window for the port that you just tested to speed up the testing of the remaining serial ports.

This device's default static IP address is 192.168.1.40.
To reset the device server, perform the following steps:
To troubleshoot this issue, you can try the following:
Before you begin, make sure that the serial device is on the same network and subnet. For more information, see this FAQ: http://www.startech.com/faq/serial_ip_networks_and_subnets. If the device starts with an IP address that is not on your subnet, change your IP address to match the subnet being used before you continue.
Ping the serial device
If the serial device and your computer are on the same network and subnet, try pinging the device.
To ping the device using a computer that is running a version of Windows XP, do the following:
To ping the device using a computer that is running a version of Windows Vista or Windows 7, do the following:
To ping the device using a computer that is running a version of Windows 8, do the following:
To ping the device using a computer that is running a version of Mac OS, do the following:
If you receive replies from the IP address, then you can see the device on the network and the issue is with something else.
Connect the serial device directly to the computer
To connect the serial device directly to the computer that you are troubleshooting with, complete the following:
Note: The second computer will need to be on the same network and subnet as the serial over IP device.
If you still cannot ping the device, contact support.
Make sure that you are working in a secure environment
If you still cannot connect to the device's web interface or by using the included software, contact support.
If you can access the web interface or connect using the included software, one at a time turn on your firewalls, antivirus programs, and security programs. Each time that you turn on software and cannot connect to the web interface or by using the included software, add an exception for the serial device to what you last re-enabled.
