If you plan to distribute your decoder to the general public, or to a large group of people within your own company, contact your protocol analyzer supplier for a Publisher ID. Publisher IDs are the first two hex digits of the decoder ID. Be sure to use a different number for each decoder file. Since no one else will have your Publisher ID, your decoder IDs will be unique.
For example, if your Publisher ID is 0x3045, your first decoder might be 0x30450000, your second 0x30450001, etc.
If you need to encrypt your decoders, you MUST have a Publisher ID. Contact Teledyne LeCroy to create encrypted decoder filesets.
