OE I-Command Digital User's Guide (3.5-Inch) Instruments (P-N 354598) Installation [Oe I-Command Digital User's Guide (3.5-Inch)]
The I-Command™ Digital Integrated Performance System uses “plug and play” networking technology based on NMEA 2000† data communications standards (National Marine Electronics Association). These standards provide communications through a serial data network utilizing a Controller Area Network (CAN) integrated circuit (IC). This network operates at 250 kb/second and allows multiple electronic devices to be connected together on a common channel for easy information sharing. Multiple digital displays can be used to monitor and broadcast equipment and engine data.
Spacing of Instruments
The minimum distances between instruments on a panel should be as follows:
•3 13/16 (112 mm) center to center for 3 1/2 in. instruments
•3 1/4 in. (95.5 mm) center to center for 3 1/2 in. instruments to 2 in. instruments
•2 5/8 in. (77 mm) center to center for 2 in. instruments
Instruments can be mounted in panels up to 1 in. thick.
IMPORTANT: Check space behind panel to be sure adequate clearance for instruments exists before drilling panel.
3 1/2 in. Multifunction Gauge
Cut 3 3/8 in. (99 mm) diameter hole in panel for 3 1/2 in. instruments.
Fastening to Panel
Insert instrument into panel hole. Install bracket and tighten nuts finger tight.
Connect the yellow wire from the instrument to the black wire of the warning horn. Connect the blue wire from the instrument to the red wire of the warning horn. Each instrument should be installed with a warning horn. Mount each warning horn in a protected area and so horn is audible for operator.
Navigation Lights (Optional)
Connecting the light wiring for the I-Command instrument to the boat’s navigation lights will provide instrument lighting if the instrument backlight setting is set to lowest setting and the boat’s navigation lights are turned ON.
If desired, connect the white wire from the instrument to the switched positive (B+) of the boat’s navigation lights and the black wire from the instrument to ground (GND).
Single Engine Power Supply Harness:
Connect the red wire of the power supply harness to the purple switched B+ accessory wire of the ignition and trim/tilt wire harness. Connect the black wire of the power harness to the black ground wire of the ignition and trim/tilt harness.
Multiple Engine Power Supply Harness:
Connect the purple wire(s) of the power supply harness to the purple switched B+ accessory wire of the ignition and trim/tilt wire harness(s). Connect the black wire of the power harness to a black ground wire of the ignition and trim/tilt harness. (Optional: connect the red wire of the power harness to a switched B+ power supply of the boat.)
Also see the “Network Specification Diagram” on page 10.
The distance between any two points on the network must not exceed 100 meters (328 ft.). Measure the distance from the Tee-connector to the last device at each end of the network. Device cable lengths at the ends of the network must be included in the total network buss length calculation.
Devices may be installed in any order. When installing temperature, pressure and fluid level sensors, install one device at a time. Configure the device, see “Advanced Setup and Operation” on page 57, then repeat this process for each sensor device being installed.
Device Cable Lengths
•Must not exceed 6 meters (19 ft.) for single device cable lengths
•Must not exceed 78 meters (256 ft.) for total device cable lengths
Maximum Number of Devices
A maximum of 50 devices can be attached to a network.
IMPORTANT: There should be no “open” or unused network device connectors. Remove unused network device connectors.
Network Specification Diagram
Device Net-style Connectors
I-Command and NMEA 2000 networks use DeviceNet Micro-C type connectors. These connectors use 12 mm threaded locking rings and are waterproof when assembled properly. All DeviceNet Micro-C connectors are compatible with the I-Command red network connectors.
Connectors with slighty different appearances supplied with I-Command or NMEA 2000 devices should NOT affect network operation. Always check pin and socket and locking ring configurations when installing connectors on a network.
Use the I-Command Product Guide, P/N 764677, or a current Accessories Parts Catalog (2008 or newer) to look up part numbers for I-Command network connectors. See your dealer.
Connectors have two configurations – Male (pins) and Female (sockets). Lubricate all connector gaskets with Electrical Grease before assembly.
Connectors should assemble easily. Do not force connectors or locking rings together.
If connectors do not match, an adapter cable may be available. See your dealer.
I-Command Network Connectors
DeviceNet Micro-C connectors offered by other suppliers.
Terminating resistors are required for accurate network transmissions. Networks must be assembled with one terminator installed at each end of the I-Command network. See the “Network Specification Diagram” on page 10.
Tee-Connectors and Buss Cables
Tee-connectors provide each device access to the network. Single Tee-connectors have two buss connectors and one device connector. Double Tee-connectors have two buss connectors and two device connectors. Network devices must be connected to the device connector of the Tee-connector.
Tee-connectors can be installed at the end of a network. Connect a network buss cable to one side and a terminator into the other.
Multiple Tee-connectors can be installed in the middle or the end of a network. Use network buss cables to connect Tee connectors or multiple Tee-connectors. See the “Network Specification Diagram” on page 10.
- Female terminating resistor (sockets)
- Male terminating resistor (pins)
- Device connector
- Buss connector
When mounting connectors, pay attention to connector alignment. Some connectors may have different mounting boss dimensions. If necessary, use an appropriate spacer behind the connector.
Mount connectors to a flat mounting surface with screws. Tighten screws by hand. Using a power driver can over tighten screws and damage connectors.
Incorrect connector mounting can bend and damage the connectors resulting in a broken network connection.
IMPORTANT: Set “ENGINE OPTIONS” on Evinrude E-TEC outboards
before power is applied to the I-Command Network.
Use Evinrude Diagnostics software to set “ENGINE OPTIONS”. Settings include:
•Set multi engine identity (engine count and engine position)
•Calibrate trim sensor
•Water pressure transducer (ONLY if equipped with water pressure transducer that is installed on engine block, P/N 5006214)
See your dealer if set “ENGINE OPTIONS” has not been completed.
