Establishing the ground
The ground wire (1.25 sq or more, local
supply) should be as short as possible. The
signal line ground is isolated from the chassis
ground, however the power line is not insu-
lated. Therefore, when connecting eternal
equipment having positive ground, do not
ground the signal line to the chassis. If exces-
sive noise shows on the screen, the ground
may be inadequate. In this case, attach a
steel plate measuring 20 cm by 30 cm on the
outside of the hull to provide a ground point.
Connect the ground wire there. Use a
"closed" type lug (
tion at the display unit. Do not use an "open"
type lug (
).
Optional equipment
Power connector
The power supply port is commonly used for
connection of external equipment such as a
GPS receiver or wind indicator. Refer to the
interconnection diagram to connect cables.
