Appendix F – Changing the NMEA0183 Identifier 
Transmitted by the SSC200 
 
The identifier for NMEA0183 sentences transmitted by the SSC200 is set by the factory to be “II”; however, some 
users may need to change this to other values.  This addendum explains how to change the NMEA 0183 identifier 
for the SSC200. 
 
Prerequisites: 
The SSC200 compass must have firmware revision 1.7 or greater. 
Instructions: 
1.  Connect the SSC200 to the PC's serial port and obtain the “cmd>” prompt per the instructions in 
Appendix C. 
2.  Type the following sentence 
 
$PMAREXE,SSC200,,DF,??,,, 
 
Where ?? is replaced by the two-character identifier you wish the SSC200 to transmit (for example, to 
change to a heading of HE, type the sentence 
 
$PMAREXE,SSC200,,DF,HE,,, 
 
*Note: For compasses with firmware revision 1.8 or greater, a NMEA 0183 checksum is optional.  For 
compasses with earlier firmware revisions, a correct NMEA 0183 checksum is required. 
 
3.  Type “exit” or simply power the SSC200 off and then on again.  You should now observe sentences being 
transmitted using the desired NMEA 0183 identifier.
