LAN setup

On the PC that is to be connected with the DSM48 (or multiple units), navigate to the network adaptor properties.

Select Change Adapter Options , right-click the relevant connection, and select Properties.
The window opposite should appear, showing network adaptor options.
Right-click on TCP/IP and the window opposite will appear.

Ensure that the button for Obtain an IP address automatically
This will ensure that the PC will connect to the DSM48 unit as a LAN host.
The next step is to connect the PC to the DSM48 unit directly via LAN cable.
In the DSM48 software main screen, click the Connection button.
The window opposite will open, showing the COM port and IP settings.
Click OK below the auto-detected IP address and the DSM48 will connect.

Once connected directly to the PC via LAN cable, it is possible to access the DSM48 network adaptor from the PC by opening a browser window (IE, MS Edge or Chrome, etc.) Type in the (auto-detected) IP address of the DSM48 into the address bar of the browser. (e.g. as shown in the connection window opposite, this would be “http://10.10.100.254”) A security window will open as follows…

Both User name and Password are “admin” by default.
Once logged into the DSM48, an edit window will open, as shown below.

If the display is not in English, click the English button.
There are many advanced settings within this menu, which should only be edited by the network administrator but the basic LAN settings are easily set as follows.
Click on the “AP Interface Setting” link and a new window will open to edit network settings.

In the AP Interface Setting window, it is possible to edit the IP address of the DSM48 for LAN connection. Enter a new valid IP address into the top field of the “LAN Setup” section (Wireless does not apply to the DSM48 unless modified)
Click “Apply” and a message will appear advising…
“Set Successfully, Restart to use the new setting”
Click on the “Device Management” link. (the login user name and password can be edited here)
Click on the “Restart” button and the DSM48 will restart.
Note: to log back in, it will be necessary to input the new IP address into the browser address bar (and new user name and password if they have been edited)

The unit can now be connected to the main LAN network and connected by its IP address in the DSP Ver3.9 application.
