6.22.1.2Installation Description
This entry allows you to modify the NMEA 2000 installation description text strings. You can enter any information you like here, such as the date the unit was installed, or the location in which it was installed, for later reference. Tools such as Maretron N2KAnalyzer allow you to view these values later. See section 3.3.4 for details on how to enter a textual value.
6.22.1.3NMEA0183 Settings
Several characteristics of the NMEA 0183 interface of the SSC200 may be programmed using the DSM250 display. This can be used for initial programming of a SSC200 compass even if only the NMEA 0183 interface is to be used after installation is complete. Figure 166 below shows the possible programming options for the NMEA 0183 interface.

6.22.1.3.1Baud Rate
The SSC200 compass supports NMEA0183 communication at both 4800 baud and 38400 baud. All SSC200 Compasses are shipped with a baud rate of 4800 baud. This value may be changed by selecting the Baud Rate option in the menu, and pressing Enter. The use the Scroll Up and Scroll Down buttons to select the desired baud rate and press Enter to save the value.
6.22.1.3.2Sentence / Rate Selection
The NMEA 0183 interface is a very low bandwidth interface. The SSC200 is capable of transmitting a wide variety of NMEA 0183 sentences, and can exceed the bandwidth of the NMEA 0183 interface if all sentences are transmitted at maximum rates, causing lost data in NMEA 0183 multiplexers or on the SSC200 interface itself. It is important, therefore, to limit the types of NMEA 0183 sentences transmitted only to those that are necessary for other products which are connected to the NMEA 0183 interface. Figure 167 below shows the SSC200 NMEA 0183 Settings
