KB01209 - How to access the web interface of an UHD-SW switch

SKU: AT-UHD-SW-51, AT-UHD-SW-52, AT-UHD-SW-52ED

Subject: How to access the web interface of a UHD-SW switch

Troubleshooting:

  • Confirm you have a router with the ability to issue IP addresses (DHCP enabled)
  • If no DHCP enabled router is available, please see steps below for how to access UHD-SW switch via a static IP address
  • Confirm the port to which the UHD-SW is being connected to on a router supports DHCP (try connecting another device such as a computer to this port and see if it gets an IP address issued)

Steps: The UHD-SW switches come with DHCP enabled by default. This means the devices can be connected to a DHCP enabled router and have an IP address issued to each switch.

To access the unit’s web interface, you can:

  1. Send an RS232 command to the UHD-SW to get its current IP info. This command is “IPCFG” followed by a carriage return. (see below for more info)
  2. You can also perform a network scan on your network/access the routers web-GUI and see what devices are attached to it. Some routers also have their own web interfaces that show the IP info of devices that are connected to it.
  3. To send a command to the UHD-SW via RS232, connect to the unit using a captive screw to DB9 cable coupled with a USB to DB9 cable. For an article on how to create such a cable, see here.
  4. After creating this cable, use your favorite serial program to communicate with the switch. Htermis a great program for Windows and CoolTerm is a great program for MAC’s. Below are the steps to use HTerm:
  5. 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 already 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, 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 the units IP configuration and current IP address. If you don’t see any IP address or see all 0’s, 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 is, please try factory resetting the Atlona unit by sending it the following command via Hterm: “Mreset + <carriage return>”. After that, try step 3 again.

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 UHD-SW and access its web interface. Login credentials are:

       

Login credentials are:

Username = root  

Password = Atlona (case sensitive)

Alternatively, some routers have their own web interfaces you can access to see what devices are currently connected to that unit.

  1. If you want to scan your network or are able to see a list of devices currently connected to the router, you can use the MAC address’ for Atlona devices which starts with “B8”. Therefore, it’s a good sign that devices with that MAC address’ beginning with B8 on your network are Atlona devices and you can try acceding those IP address’ via your web browser.
  2. You can also use a free IP scanner such as those you can download from the Google Play Store and iTunes App store. Please note, for the network scan to work correctly, your phone/pc will need to be connected to the same network as the Atlona device.
