C120 and DSM 30 software downloads

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Hydra Sport 25,

The subject software update is not applicable to DSM30/300 Sounder Modules which have been interfaced to C-Series Classic MFDs. Do not update the software of your DSM.

The B117 Transducer is designed to support depth alone. Raymarine offers the E66071 (Plastic) and E66072 (Bronze) ST800 / P120 Speed/Temperature Transducers to add speed and temperature data to a system such as yours. These transducers feature a Y-Cable to permit them to be installed between the DSM and the B117's plug.
