OpenLNS CT User’s Guide 47
If an OpenLNS CT drawing does not have a digital signature, you will see the macro warning dialog
and will have to enable macros every time the network drawing is opened, provided Visio’s macro
security is set to medium (the default). In order to change Visio’s macro security, open the Tools
menu, point to Macro and then select Security. A dialog opens allowing you to select Low, Medium,
or High security.
• If you select Low security, you will never see the macro warning.
• If you select Medium security, you will be prompted to enable macros for unsigned network
drawings or network drawings signed by companies that have not been added to the trusted
signatures list.
• If you select High security, macros will automatically be disabled (and OpenLNS CT will not
function) for unsigned network drawings, and you will be prompted to enable macros for network
drawings signed by companies that have not been added to the trusted signatures list.
Visio’s security level is persistent. When you change Visio’s security level, it will be the security level
for Visio every time it is started until you change it again.
Tip: If your drawing contains ActiveX controls, change the security setting to Low. Otherwise, Visio
will prompt you each time the drawing is opened as to whether to activate the controls.
Creating an OpenLNS CT Network from an Existing OpenLNS
Database
You can create a new OpenLNS CT network design by opening an OpenLNS network database that is
not already associated with a drawing. OpenLNS CT will then create a drawing for the database. You
can use this procedure to import an existing network into OpenLNS CT when the network was created
with an OpenLNS application other than OpenLNS CT. To create a new OpenLNS CT network from
an existing OpenLNS network database, you must use OpenLNS CT on a local client.
To create a new OpenLNS CT network design from an existing OpenLNS database, follow these steps:
1. Click Start on the taskbar, point to Programs, point to Echelon OpenLNS CT, and then select
OpenLNS CT. The OpenLNS CT Design Manager opens.
2. Under Existing Network, select which database you want to open in the Database Name list and
then select <none> in the Drawing Directory list. A Create Drawing command will appear in
place of the Open Network command.
