EST gateway installation for Yamaha EX
NOTICE!
The Yamaha EX EST gateway harness does not have ignition/wake-up
lines for the PCM.
Ignition lines for the PCM should remain connected to the Yamaha key
accessory switch.
The EST gateway is an electronic interface device that connects the Optimus
control system to the OEM shift and throttle control system. It passes shift
and throttle commands from the joystick to the engine manufacturer's EST
system, and monitors station selection, network status and ignition state.
Location
A gateway (EG1860) and joystick may only be installed at the main station
control head of the vessel. The gateway should be installed underneath
the dash and as close as practical to the control head. Before installation,
test fit with harness CM20046 to ensure that the harness connects to the
remote control and the gateway without strain.
Installation
Install the gateway with the strain relief plate and screws as shown in figure
7-15. The preferred orientation is vertical with connections facing down,
but it may also be installed horizontally. Avoid mounting the gateway with
the connections facing upwards.
Use cable ties to secure the harness cables to the strain relief plate as shown
in figure 7-16.
