The following schematic shows the Recommended Yaesu FT-950 Interconnection Diagram. This connection made by mounting the board with metal standoffs or connecting the interface board mounting hole to the metal interface enclosure. You may also ground shields directly to the metal enclosure, if desired. Make sure FT-950 RTTY menu items 060 (Transmit Polarity), 062 (RTTY Shift), and 063 (RTTY Tone) are set properly. Recommend settings are 060 = Normal, 062 = 170, and 063 = 1275 or 2125. The 1275 setting provides a more pleasant listening experience.
