[CA] [CA11] DST800 power off depth

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Martin,

Analog DST800 transducers or Smart depth transducers (NMEA 2000 or NMEA 0183) will continue to ping in search of a bottom as long as power is supplied to the iTC-5 or is supplied to the Smart transducer respectively. While it is conceivable that one may be able to install an ON/OFF switch in the NMEA 2000 Smart transducer's spur cable's power lead, doing so would also disable the transducer's other functions (if any). In the case of the DST800, installing an ON/OFF switch would disable the transducer speed and temperature data as well. Raymarine's MFDs and instruments do not feature a setting to switch the ping ON/OFF for instrument depth transducers. As you have suggested those having such concerns would be advised to install individual depth and speed/temp transducers.

In systems featuring a dedicated depth instrument (ex. i50 Depth) having an analog depth transducer has been interfaced to that instrument, the dedicated depth instrument may be switched OFF to cease pinging. In systems featuring an Tridata instrument having an analog triducer interfaced to it, the instrument may be configured from a Depth Master to a Depth Repeater to support cessation of pinging.
