PIX/PDQ Server
OpenEMPI provides support for the handling of HL7v2 messages that are compliant with the IHE PIX/PDQ profiles specifications (support for HL7v3 and FHIR-based messages is provided through a web services interface which is separate from the service described here). By default, when the OpenEMPI instance starts it also automatically start the PIX/PDQ server that listens for incoming HL7v2 messages but this setting may be changed. In such cases you can use the buttons offered by this page to manually start and stop the PIX/PDQ server.
