Specifying a Default Message

To test that the default message works:

• Click the Browse icon on the toolbar. The Message Browser window appears.
• Copy the following message:

	The above ORU^R01 message is used to test the default message functionality since it does not match an ADT^A04 or ADT identity.

• Paste the above message into the top pane of the Message Browser, and click Parse. Two things occur: (1) A yellow panel appears, indicating that some segments are unrecognized; (2) Chameleon successfully ignores the message. Since you do not care about any segments besides the MSH segment, no action is required for (1).

Chameleon Successfully Ignores the Message
