SeaStar i7700 is an electromechanical system that replaces a
traditional cable-operated engine remote control with an electronic
control. Shift and throttle settings are sent over a serial data network
to electro-mechanical actuators, where they are converted to cable
motion. The elimination of mechanical cables to the control head
simplifies multi-station installations, especially when a station is
installed onto a flybridge or tower that is removed for shipping. The
system supports the installation of up to three control heads.
The i7700 system consists of the major components listed below.
CAN Network
CAN (controller area network) is a serial network protocol that is
widely used in marine and automotive control systems. Each device
(node) on the network can send and receive data using specially
formatted messages. The ability to reliably communicate data
between devices is what enables the functionality of i7700.
i7700 implements the high-speed CAN protocol using DeviceNet
harnesses and connectors. We refer to the network as CAN2 in the
documentation to distinguish it from other CAN protocols used on
SeaStar products.
Control Head
The control head looks much like a conventional mechanical remote
control, but it is an electromechanical device that converts lever
position into digital messages that are sent over CAN2 to the shift
and throttle actuators. The control head features adjustable lever feel,
status lights, a synchronous trim switch (optional), and control buttons
for added functionality.
Shift and Throttle Actuator
The actuators are electromechanical devices that receive digital
commands on the CAN2 network and convert these commands into
movement of a mechanical cable for gear selection and throttle control.

3.0 SYSTEM OPERATION
3.1 Before Each Use
1. Check your steering system.
If your vessel has a hydraulic steering system, ensure that the
fluid level is correct. Check that the steering responds
immediately and correctly when you turn the steering wheel(s),
and that the hydraulic hoses move freely through the range
without snags or hang-ups.
2. Inspect all and mechanical cables and electrical harnesses for
wear, kinks, or damage.
Check all electrical harnesses and mechanical cabling for
abrasion, wear, rubbing or chafing. Check that all connections
are tight and free of corrosion.
3.
Check for binding, loose or worn shift/throttle control components.
Check all shift and throttle cables and harnesses for signs of wear,
damage or chafing. Check that all linkages and cables move freely
and are not binding or corroded.
4. Verify proper shift and throttle response for all control levers.
Check that all shift and throttle levers operate freely and cause the
engines to shift accordingly. Put the engines in neutral idle mode
and confirm that the throttle responds correctly and returns to idle.
5. Verify that no faults or warnings are indicated on the Shift and
Throttle Control Head.
Rapidly flashing
LEDs on the control head indicate that there is a
Warning or Danger fault. Refer to section 4 for more information.
FAILURE TO ADHERE TO THESE WARNINGS MAY RESULT IN LOSS
OF BOAT CONTROL, LEADING TO POSSIBLE EJECTION FROM VESSEL;
CAUSING PROPERTY DAMAGE, PERSONAL INJURY AND/OR DEATH.
WARNING
IT IS RECOMMENDED THE FULL SYSTEM INSPECTION BE REVIEWED
ON A REGULAR BASIS TO RETAIN FAMILIARITY.
DO NOT OPERATE THE BOAT IF ANY COMPONENT IS NOT IN PROPER
WORKING CONDITION.
WARNING
WARNING
3.2 First Time Use
Before starting the engines for the first time, familiarize yourself with
the shift and throttle controls and the features described in section
3.3. With the engines and control system off, move the control
levers over the full range until you are familiar with the feel. The lever
feel can be adjusted if desired. See section 3.3.3.

3.3 Control Head Operation
The control head is the user interface for shift and throttle control.
There are two types of control head used with the i7700 system: single
lever (STM), used on single-engine applications, and dual lever (DTM),
used on multi-engine applications. Both types of control head are
top-mounted; a side-mount single lever control head is not available
for the i7700 system.
The i7700 Quick Reference Guide provides a summary of the control
head operation and should be kept on the vessel at all times.
BE VERY CAUTIOUS WHEN FIRST ENGAGING THE GEARS TO ESTABLISH
THAT FORWARD IS TRULY FORWARD AND REVERSE IS TRULY REVERSE.
A QUICK IN-AND-OUT OF GEAR TEST IS RECOMMENDED. ENSURE
THAT THE BOAT IS CLEAR OF ALL OBSTACLES FORWARD AND AFT
BEFORE CONDUCTING THIS TEST.
WARNING
