E120 classic

Welcome to the Raymarine Forum Eirinnrose,

Q1. I also have a broken pin on my 2005 E120 MFD. I have two E120's interfaced with Sea Talk, with one being the master. Do I need to assign the other 120 as the master to utilize the chart card reader on the second MFD?
A1. Should the two MFDs be interfaced to one another via Ethernet (SeaTalkhs) networking, then these two MFDs will share Navionics cartography data read from the reader of either MFD. However, before attempting to use the chart card in the second MFD it is strongly recommended that the chart card be inspected to ensure that the broken pin from the MFD's memory card reader is not lodged within the female pin(s) of the chart card.

Q2. In assigning the second one as the master, do I need to switch any wiring from one FMD to the second?
A2. There is no need to change the Data Master setting of the MFDs. However, should you at some point in the future elect to change the Data Master setting, then the Data Master MFD will need to be interfaced to the SeaTalk bus and/or SeaTalkng/NMEA 2000 backbone.
