I tried DBT and DPT, and never had any luck getting depth to show on my SC-1000.
I will look at the boat tonight and tell you exactly what sentences I enabled as output. (Incidentally, I am in the process of pulling my SC-1000's and going only w/ VVL and an MFD for gauges, curious why you want to still run the MercMonitor w/ a VVL; I thought VVL also gave fault decodes in full text).
Be sure you set Baud Rate to 4800.
Set merc-monitor to use GPS speed,
Minimize the number of sentences you use, again, not sure you need much past RMB and RMC.
Found this info on the web, I think it is a list of all the NEMA-0183 sentences.
