E120 Classic MFD with DSM300
I am unable to select the proper speed/temp transducer (ST800) in the Sounder Configuration menu on the E120 MFD. The ST800 appears in the menu but when I select it, the choice changes to "UNKNOWN" as soon as I press enter. For now, I select the ST600 and adjust the speed calibration to 130% to get accurate speed data displayed.I am using a Y-Cable with the DSM-300 and have the B260 Depth Transducer and the ST800 Speed/Temperature Transducer.Does anyone know a fix for this issue?See More
