KB01412 - How to access the web-interface of an Atlona system with DHCP enabled

SKU: Any web-GUI enabled Atlona product (most devices with LAN ports)

Subject: How to access the web-interface of an Atlona system with DHCP enabled


Most Atlona hardware (with TCP/IP capabilities) come with DHCP enabled. This means that simply by connecting the unit to a DHCP enabled router will allow the Atlona device to be issued an IP address. This IP address can then be entered into any internet browser of a computer on the same network as the Atlona system, which will allow you to access the devices web graphic user interface (web-GUI).

For convenience, Atlona offers a variety of ways to find the IP address of our products:

  • Devices with on-screen displays (aka devices that display a menu on the display/projector being used) or units with a front panel display can show its unique IP address. You can also send these devices an RS232 command (IPCFG) to get their IP information.


  • Devices without on-screen displays or front panel LCD displays can be sent an RS232 command (IPCFG) and they can then report back their IP information via RS232 feedback.


  • You can also find the IP information of most devices by performing a network scan and matching the Atlona units unique MAC address (typically start with “B8:98”). The mac address can typically be found on either the bottom of an Atlona product or on the box it was packaged in.


  • Some devices also allow you to turn off DHCP or set a static IP address using a specific button press sequence. For more information, please search for your products SKU in our help center to find the unique article for this process. Otherwise, please see below for the default method of determining a units IP information using RS232.

Using RS232 to find a products IP information:

To communicate with an Atlona device via RS232, you will need:

  1. A computer
  2. USB to RS232 cable
  3. DB9 to Captive screw cable
  4. Serial communication software (Hterm is a free program for Windows, for which we have a users guide here).

Once you have the required components, you can establish an RS232 connection with your Atlona device using these steps:

  1. Open HTerm and start a connection by choosing the correct COMM port and baud rate (115200):

Please note, you will need to have a comm port selected (HTerm will try to automatically find the comm port). If you don’t have any comm ports showing up, please check your USB to RS232 cable and try another USB port. You can also check port settings and port #’s in Device Manager:

*Please note, your port #’s may change*


After establishing a connection in Hterm:

  1. You should see the following message in the bottom right corner of the program:
  2. Next, send the “IPCGF” command to the unit in order to get a response with the IP info: Please note, the command will need to be sent with a carriage return thus make sure the “send on enter” section states “CR”:               
  3. After sending the IPCFG command, you will then see RS232 feedback (in Hterm) with the Atlona units IP configuration and current IP address. If you don’t see any IP address, please confirm you have established an RS232 connection by sending the command “Type” which should reply back with the model number of the Atlona device. If it doesn’t reply with anything, check your RS232 cables and consider installing a null-modem adapter or flip your TX and RX pins on the Atlona unit.
  4. If you see all 0’s get reported back as the IP address, this means your network was unable to issue the Atlona unit a DHCP address. This might be because the network is configured to work with static IP address’ or that there is an issue with said network. To test your network, connect another DHCP enabled device and see if that it issues an address. If it issues DHCP addresses to other devices, please try factory resetting the Atlona unit by sending it the following command via Hterm: “Mreset + <carriage return>”. After that, try step 2 again.

Please note, some Atlona devices will default to a static IP of if they do not get an IP addressed issued to them using DHCP. If you see what your Atlona unit is reporting a there is a chance you don’t have DHCP capabilities on your router but you can manually set your PC to a static IP address that matches the range of the Atlona unit and establish communication in this manner.

After sending the “IPCFG + <carriage return>” command, if you see an IP address get reported from the switch such as shown above, you can type this address into any PC that is on the same network as the Atlona unit and access its web interface. Below is an example of what the web-interface looks like for an Atlona unit:


Username: root

Password: Atlona
