How do I reset the SSC200 to send the factory default NMEA 2000 messages (or PGNs)?

You reset the SSC200 to transmit the factory default messages using Maretron’s DSM150 or DSM250 display in the following way:

1. Enter menu mode, scroll to "Configuration:" and press
2. Scroll to "Device Configuration:" and press 
3. Scroll to the row containing the SSC200 and press 
4. Scroll to "Reset Factory Defaults" and press  twice

Beware that resetting factory defaults resets all settings back to factory defaults, not just the transmitted messages.
