DSM-300 s/w Update, yes or no

[Chuck - Raymarine - Moderator]

lotharjt,

Failure to apply power to the DSM quickly enough after commanding the MFD to UPGRADE REMOTE UNIT ON SEATALKHS can cause MFD to fail to update the bootloader software. Should this occur, then one would simply start the process again. Additionally, the bootloader software is very quick to install and should the operator not be viewing the screen during the entire process, then the operator may fail to note completion of the bootloader software's installation. For this reason, it can be very helpful to have a someone assist with removing and applying power to the DSM while the other person executes commands via the MFD and monitors process. Please additionally note, that should circuitry problems be responsible for NO DSM or DSM CONNECTION LOST alerts, then it may not be possible to update the DSM's software ... see my prior response specifying to send the DSM to Raymarine's Product Repair Center or replace the DSM with a CP370.
