PC Software Operation

Setting up

The Citronic DSM26 can be operated individually from a PC via USB and can also be linked in multiples over a wider, long-distance network via LAN connection. A maximum of 250 units may be linked together by this method. If connecting via LAN, refer to the "LAN Setup" section.

Before connecting a DSM26 via USB, install the software from the supplied disc (also available to download from www.avsl.com). Locate the driver file “PL2303_Driver" and double click to install (this will usually require a re-start once installed). Connect the DSM26 via USB or LAN as shown below and double click the file named "DSP Ver 3.9".

Image Description: A diagram illustrates PC connectivity. A single DSM26 unit connects to a Laptop/PC via USB. Multiple DSM26 units can connect via LAN to a Router, which then connects to the Laptop/PC. The diagram shows two DSM26 units connected via LAN, labeled "DSM26 unit #1" and "DSM26 unit #2", with a third placeholder "DSM26 unit #250". Each DSM26 connected to the network should be set up with a different IP address (via USB) first.

Connection

In order for the PC to communicate with the DSM26, it is necessary to establish a connection. Click on the "Connection" button.

The following menu will be displayed:

Image Description: A "Connect" dialog box is shown. It features a "Com Connect" section with a dropdown for "Com Select" (e.g., COM4) and an OK/Cancel button. Below it is a "Network" section with fields for IP address (e.g., 10.10.100.254) and an OK/Cancel button. The "Com Select" field is for USB connections, while the "Network" field is for LAN connections.

The software will normally detect the correct COM port. Click OK to confirm the USB connection. If unsuccessful, try a different COM port. If the COM port is not detected automatically, open the PC's Hardware Device Manager (e.g., "Start > Settings > Control Panel > System > Hardware > Device Manager") and look in "Ports" to identify the correct port for the DSM26. For LAN connections, enter a workable IP address into the "Network" field.

Program Menu

Clicking the "Program" button opens a window for managing programs:

• Load/Delete programs: Load or delete user data or effect data from the device or PC.
• Save/Load all programs: Save or load all programs from/to the PC.

To load a program, select it and click "Load". To delete, select and click "Delete". To save after editing, select a program slot, enter a name, and click "Save". Programs can be saved to or loaded from PC by checking the relevant PC buttons (C, D, E, or F) and clicking "OK".

Channel Setup

Clicking the "Ch Setup" button opens a window to rename each input and output channel by typing in the respective field and pressing Enter.

Copy Function

Clicking the "Copy" button opens a window to copy all settings across inputs or outputs from a source to a target, then click OK.

System Menu

Clicking the "System" button opens a window for system settings:

• Backlight: Select constant on or auto-off after 25 seconds.
• Interface Information: View and edit interface details.
• Temperature: Adjust maximum temperature before cut-out.
• Filter Display: Select filter bandwidth or Q parameter display.
• Scene Change/Setup: Assign buttons 1, 2, and 3 as hotkeys for favorite programs.

LAN Setup

To connect the DSM26 via LAN, configure your PC's network adapter properties. In Windows 10, navigate to Settings > Network & Internet > Ethernet, then select "Change Adapter Options". Right-click the relevant connection, select "Properties", then right-click "Internet Protocol (TCP/IP)" and select "Properties". Ensure "Obtain an IP address automatically" is selected to connect the PC to the DSM26 as a LAN host.

Connect the PC to the DSM26 unit directly via LAN cable. In the DSM26 software, click the "Connection" button. Select the COM port for USB or enter the IP address for LAN. Click OK.

Once connected via LAN cable, you can access the DSM26 network adaptor from your PC by opening a web browser (e.g., IE, MS Edge, Chrome) and typing the DSM26's IP address (e.g., `http://10.10.100.254`). A security window will appear; log in with the default username and password "admin".

If the display is not in English, click the "English" button. For network settings, click on the "AP Interface Setting" link. Here you can edit the IP address, SSID, and other network parameters. After applying changes, a message will confirm successful setup and prompt a restart. Click "Device Management" to access user name/password settings and the "Restart" button.

To log back in, use the new IP address in the browser address bar. The unit can now be connected to the main LAN network and accessed by its IP address in the DSP Ver3.9 application.
