MAUI Oscilloscopes Remote Control and Automation Manual
Configuring DCOM Connections
The Windows Distributed Component Object Model (DCOM) permits the distribution of different
components of a single application across two or more networked computers and the remote display and
control of applications. Accessing a networked oscilloscope remotely via DCOM is equivalent to logging on
to the oscilloscope itself and executing programs "locally."
In order to access the oscilloscope's object hierarchy without ActiveDSO or a VISA driver, or to use
XStreamBrowser remotely, Windows DCOM settings must be configured to permit the controller and
oscilloscope to control applications residing on the other.
Note: DCOM is pre-configured on WaveSurfer 3000 oscilloscopes, which run the Windows CE
platform and do not allow access to a desktop. Install the WaveStudio software, which displays the
COM hierarchy of a connected device when Automation Browser is selected.
To complete this process, you will:
1. Configure the remote PC to permit DCOM connections.
2. Configure the oscilloscope DCOM settings, including creating user accounts (if required).
3. Test the connection.
Note: You must have Administrator privileges on both the PC and the oscilloscope to complete
DCOM configuration.
A. Determine Windows OS
If you do not know the operating system running on the controller or the oscilloscope, go to the Windows
desktop, right-click on the My Computer icon and choose Properties. Follow the procedures below
indicated for your operating system.
B. Determine Network Domain and User Accounts
If the oscilloscope is not on the same NT domain as the controller PC, you will need to set up an account
for the PC user in the oscilloscope domain using the exact same user name and password as on the PC. That
same user must also be allowed into the oscilloscope DCOM section. Before proceeding, consult your
Network Administrator regarding your network configuration.
If the machines are on different domains, verify the user name and password for each user account that
will be used to send Automation commands to the oscilloscope. You will need this information to complete
the configuration on the oscilloscope.
C. Install XStreamBrowser
Download and install the XStreamBrowser on the controller PC.
Note: XStreamBrowser is installed by default on the oscilloscope.
