32 DSM300 Operation with PLUS Series DisplaysThe changes do not take effect until after ENTER is pressed. Consult your NMEAinstrumentation documentation to determine which strings should remain ON.Note:The DSM300 outputs the same depth value for DBT and DPT, regardless of theDepth Offset value in Sonar Setup.Cursor EchoYou can set up an integrated system so that radar and chartplotter displaysconnected via SeaTalk can display each other’s cursors.Cursor echo functions so that you can display a chart cursor on the radar picture,or a radar cursor on the chart picture (you cannot display a remote radar cursor ina radar window nor can you display a remote chart cursor in a chart window).When the appropriate options are switched on, each display shows its own cursor,plus the cursor of the other display with appropriate cursor text (RDR or CHRT) toindicate its origin. This means that you could move the cursor over a target on theradar display and check the identity of the target by looking at the radar cursorposition on the chartplotter.Press the CURSOR ECHO soft key to display the cursor transfer soft keys.
