Use the Stream ID field on the Radio tab to specify the SID code that is to be included in the header of the messages transmitted to and from this radio.
This field only applies if the Send SID check box is selected on the configuration Form of the Simple Trio Diagnostics Channel that is used for communications with the radio (see Specify Whether to Include the Stream Identifier in each Data Packet).
In many cases, you can leave the Stream ID at the default of 0 (zero).
If the configuration in the radio has been modified to enable multistream functionality, use the Stream ID field to specify the SID code address that is configured in the radio unit.
For information on SID codes and multistream functionality, see the documentation supplied with your Trio radio equipment.
