The wireless serial over IP device server lets you remotely access and manage an industrial serial device over a WiFi or wired network, with the added benefit of redundant power inputs to prevent downtime in the event of a power surge or failure.
For more control options, the device server is compatible with the free, StarTech.com (NETRSAPP). When coupled with the NETRS232485W, this handy application for iOS, Android, and Chrome Browser lets you build a custom serial control interface that’s tailored to your specific application.
To eliminate the hassle of laying additional Ethernet cable, this wireless device server lets you connect your RS232/422/485 serial device in a location where a wired network connection is unavailable, with support for 802.11 B/G WiFi connections and a 10/100Mbps wired network port for added flexibility.
Ideal for industrial environments, the serial to Ethernet device server accepts wide-range 12-48V DC power input via a terminal block or an optional DC jack, enabling you to add redundant power with a secondary adapter (e.g. 12V DC 1.5A Power Adapter SKU: IM12D1500P - sold separately).
This device server supports baud rates up to 230.4Kbps which provides a smooth connection to your serial devices. The server also offers support for HTTPS, SSH and SSL to ensure secure communication, while integrating remote Telnet configuration and support for IP, HTTP, ICMP, DHCP, TCP and UDP protocols. You can customize the serial device server to suit your application with versatile browser-based or virtual com port software configuration.
Ensuring performance in harsh environments, this serial device server offers 8KV air, and 4KV contact ESD (Electrostatic Discharge) protection and features a rugged, IP-30 case design that is both DIN rail and wall-mountable.

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 192.168.10.2.
To perform a factory reset, hold down the Reset button for 5 seconds. The LEDs will blink red, to indicate that the device has been reset.
You should not upgrade your device's firmware if you do not have any issues with the functionality of your device. The only time you should consider an upgrade is if you are experiencing a problem with the device, and you have confirmed that the firmware addresses this problem. You can confirm this is the case by reviewing the documentation included with the firmware or by consulting with our Technical Support team. Incorrectly upgrading firmware can result in diminished performance so it is best to contact StarTech.com if you would like to perform this operation.
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.
One of the most common applications of a network serial device is to use it to make a standard serial device accessible on a network. To do this, you need to connect a standard serial device to the DB-9 port on the network serial device. Next you need to connect the network serial device to a TCP/IP network using an Ethernet connection, and then install software on a client machine in order to access the network serial device. The software on the client machine communicates with the network serial device and creates (maps) a virtual COM port on your computer system. The virtual COM port is identical to a physical COM port and can be used in the same way.
You can use two network serial devices to extend a serial connection over a TCP/IP network. To do this, you need to configure one serial device as a client and the other as a server. The client and server are configured to transmit and receive data to their respective IP addresses and TCP ports. The serial settings must match for all connected serial devices, including the UART on both units. Depending on the serial device that you are using, you can use the provided software or the web interface to set the configurations.
You can use a network serial device to translate UDP data to a standard serial connection. The serial device is configured to listen for UDP traffic from specific IP addresses and ports, and will asynchronously transmit the data out of the serial port on the device. To do this, you need to configure UART on the network serial device to match the specifications of the serial receiver.
