This section describes how to add an EHS PDSS pass-thru packet to a TReK Database. If your packet is defined as a pass-thru packet, you can use the TReK API to retrieve the header parameters or the data zone portion of the packet, but not any of the individual parameters in the data zone of the packet. Once you have added a pass-thru packet to a TReK Database, you can use capabilities on the Metadata application’s Database tab to export the packet definition to a TReK metadata file.

1.	Go to the Options menu and select ‘Add EHS PDSS Payload Pass-Thru Packet to TReK Database’.
2.	In the ‘Add EHS PDSS Payload Pass-Thru Packet to TReK Database’ dialog, enter the database information. You can use an existing database or create a new database.
3.	In the Packet Information area, enter the APID for your packet.
4.	Push the Apply button. The results will be displayed in the Results area.
