Frequently Asked Questions

Before You Buy

Virtual COM port

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.

Serial IP extender

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.

UDP to serial adapter

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.

Troubleshooting

This device's default static IP address is 192.168.0.35.

When experiencing either issue, complete the following:

  1. Close the IP-Extender Manager software.
  2. Right-click on the IP-Extender Manager icon and click Properties.
  3. Click the Compatibility tab.
  4. Select the Run this program as an administrator check box.
  5. Click Apply and OK.
  6. Relaunch the software.

There are several different ways that you can reset these devices to the factory settings. The following steps list the methods in order of easiest to hardest to perform.

Use the included software

  1. Open IP-Extender Manager.
  2. Right-click the serial over IP device and click Advanced.
  3. Click Restore Defaults.

Use the web interface

  1. To log into the web interface for the unit, type its IP address into a web browser and enter the password. By default, the password is admin.
  2. Click Network Settings.
  3. Click Restore factory defaults and reboot device.

Note: You can reset individual ports by going into Port Configuration and clicking the Reset button underneath Port Reset.

Reset the hardware

  1. Disconnect all of the cables from the serial over IP device. There should not be anything plugged into it.
  2. Remove the four screws from the bottom of the unit.
  3. Remove the cover.
  4. Short J15 (located near the Ethernet connection) with a jumper.
  5. Reconnect the Ethernet cable.
  6. Reconnect the power cable.
  7. The orange light on the Ethernet connection will illuminate and the green light will stay dark.
  8. When the green light comes on, the hard reset procedure is complete.
  9. Disconnect both cables from the serial over IP device.
  10. Remove the jumper from J15.
  11. Replace the cover.
  12. Replace the four screws.
  1. Make sure that the serial device is on the same network as your computer.
  2. In an Internet browser, enter the IP address of the unit. The default IP address is 192.168.0.35.
  3. In the password field, enter the password. The default password is admin.
  4. Click Configure.

This is normal behavior. The software says connecting when data is being transferred. When data is not being transferred, the software says disconnected. The disconnected message does not mean that the device is not working.

If you are experiencing any issues in Windows 8 with the IP-Extender Manager software, complete the following:

  1. Right-click on the IP-Extender Manager software and click Properties.
  2. Click the Compatibility tab.
  3. Choose to Run this software in compatibility mode for Windows 7.
  4. Select the Run this program as an administrator check box.
  5. Click Apply and OK.

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.
