Standard Horizon DS41 - Manual (Page 17)

DS41 Owner’s Manual 16
The DS41 can be configured to operate as a
NMEA repeater. In this mode it will display depth
information from any depth sounder outputing
DPT or DBT NMEA depth data (no other NMEA
depth sentences are supported).
Notes:
1) The only information displayed from
the DPT and DBT sentence is depth
below the transducer. The user must
enter keel offset values and alarm
settings as required.
2) When a slave has no depth
information, the display will alternate
between -- and -SL. This will occur if
the master unit has no depth reading
or if the data link from the master is
inadvertently broken.
