The first step is to create the channel that accepts HL7 messages as input and uses the VMD file to transform the HL7 messages. To create this channel:

• In Iguana, click the Dashboard tab.
• In the Dashboard Control Panel, click Add Channel. The Add Channel screen appears.
• From the Source list box, select LLP Listener.
• From the Destination list box, select To Channel. The Add Channel screen now looks like this:

• Click Configure Channel. The Configure New Channel screen appears:

• In the Channel name field, type tutorial.
• Click the Source tab. The Source: LLP Listener panel appears:

• In the Port field, type 5346. (If this port is already in use, specify any unused port.)
• Click the Filter tab. The Filter panel appears.
• Select the Use filter check box. Fields appear that allow you to configure filtering for this channel:

• In the Full filter VMD path field, specify the path of the VMD file you created in step 2.
• From the Transformation mode list box, select Scripted transformation. The Configuration name field appears; its value can be left as default.
• Click Add Channel to create the channel.

When the destination component is To Channel, you do not need to supply any information:

The other channels that you define will specify this channel as their source.
