[CA11] Upgrade C120 to E120 Classic

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum wbdoll,

The sockets of the E-Series Classic MFDs and C-Series Classic MFDs are identical for the MFD's Power Cable, Analog Radar Cable, and NMEA 0183 Cables. The SeaTalk socket of the C-Series Classic MFDs was designed to accommodate a press-fit 3-pin SeaTalk plug. In contrast, the SeaTalk/Alarm Cable of the E-Series Classic MFD features a twist locking 6-pin connector. As such, the currently installed SeaTalk cable's leads would need to be spliced to E-Series Classic MFD's SeaTalk/Alarm Cable (red to red, yellow to yellow, and shield to black respectively).
