+==== Advanced usage in subVI ====
+If you want to access a database from a SubVI of a larger DQMH module, but you don't want to start the entire module, there's an easy way to get a DB-Connector running in the SubVI without starting the whole project:
+  - Configure DB-Connector in your project
+  - Open "Test DB-Connector.vi" and run
+    {{ code:open-source:hse-libraries:hse-core-libs:db-con1.png?nolink |}}
+  - Press "Run New Module Instance"
+    {{ code:open-source:hse-libraries:hse-core-libs:db-con2.png?nolink |}}
+  - Your SubVI should already look somewhat like this:
+    {{ code:open-source:hse-libraries:hse-core-libs:db-con3.png?nolink |}}
+  - Copy value from "Active Modules" to your SubVI "DB Module ID" front panel element and run. The DQMH request VIs send commands to the running instance of DB-Connector
+  - When done, use “Stop Module Instance” in DB-Connector and close your SubVI.
