SSC300 User's Manual

4.4.1 Variation Source Selection via Maretron Display

You can program the SSC300 to use a particular variation source using a Maretron display
product (e.g., DSM150, DSM250, or N2KAnalyzer software). Refer to the display product user's
manual for details on programming the SSC300 to use a specific variation source.

4.4.2 Variation Source Selection via NMEA 0183 Interface

You can program the SSC300 to use a particular variation source through the NMEA 0183
interface. Refer to Appendix A for details on programming the SSC300 to use a specific variation
source.

5 Rate of Turn

The SSC300 is capable of measuring a vessel's rate of turn and outputting the information over
both the NMEA 0183 and NMEA 2000
programmable damping period where the filter time can be increased for very slow turning
vessels such as tugs pushing barges. Also, the SSC300 rate of turn indication may be zeroed
to correct for any temperature-induced offset.
The SSC300 can be programmed with different damping periods and have the rate of turn
indication zeroed using one of two possible procedures.
1. Using a Maretron Display (Section 5.1)
2. Through the NMEA 0183 Interface (Section 5.2)

5.1 Rate of Turn Damping Period Selection with Maretron Display

You can program the SSC300 to use a particular rate of turn damping period using a Maretron
display product (e.g., DSM150, DSM250, or N2KAnalyzer software) . Refer to the display
product user's manual for details on programming the SSC300 to use a specific damping period.

5.2 Rate of Turn Damping Period Selection by NMEA 0183 Interface

You can program the SSC300 to use a particular rate of turn damping period through the NMEA
0183 interface. Refer to Appendix A for details on programming the SSC300 to use a specific
damping period.

5.3 Rate of Turn Zeroing

The SSC300 may be used as a rate of turn indicator, which should read zero when the vessel
is not turning. It is possible that the rate of turn indication has an offset; that is, it may show a
non-zero value when the vessel is at rest. This offset changes with temperature but the SSC300
has the ability to remember the offset at different temperatures. You teach the SSC300 by using
"Rate of Turn Zeroing". It is possible to do "Rate of Turn Zeroing" using a Maretron display
product, such as the DSM150, DSM250, or N2KAnalyzer software (please refer to the display
product user's manual for details).
