138 Working with Blocks
Connecting B l ocks
To connect blocks and modules:
1. Move the cursor to the desired output node. The cursor changes to a
soldering iron.
2. Press and hold the mouse button.
3. Drag the soldering to the desired input node or anywhere inside the
block. As you drag, a red line representing the connection appears.
4. When the soldering iron is in the appropriate location, release the
mouse button. The red line turns green.
Important: Green lines indicate a valid connection. Therefore, if
while attempting to draw a connection, the red line does
not turn green, you are attempting an invalid operation.
