EST gateway installation for Yamaha DEC
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 (EG1820) is required at each control station equipped with a joystick.
It should be installed underneath the dash and as close as practical to the
control head. Before installation, test fit with harness CM20023 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
7-6. 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 7-7.
