Parts Required
The installation requires the use of an Electronic Service Tool equipped with the proper software for the installed engine.
NOTE: The use of appropriate Engine Troubleshooting Guides and Schematics (from Service Manual) is recommended to aid OEM customer installation of electronic components and systems.
Operator Station Grounding Connections
| NOTICE |
|---|
Improper grounding will cause uncontrolled and unreliable circuit paths. This can result in damage to the engine crankshaft main bearings, crankshaft journal surfaces or other engine components. This may also cause electrical activity which may degrade vessel electronics and communication equipment. |
All engine ECMs must be connected to the Engine Room -Battery Bus Bar. Caterpillar recommends a separate Engine Room -Battery Bus Bar for all engine ECM connected electronics. This ensures that the ECM and all associated components, including switches, sensors and electronic display modules have a common reference point. All -Battery connections should begin at -Battery connection of the component being wired and terminate at the -Battery Bus Bar.
The connection from the Engine Room -Battery Bus Bar to the bridge display Station -Battery Bus Bar should be made with a minimum of 12 AWG wire. Each Station -Battery Bus Bar is for the display modules only and should not have any other electrical components connected to it.
1. Connect from the Engine Room -Battery Bus Bar to the minus battery pin on the ECM Customer Connector using 14 AWG wire.
NOTE: Refer to the table for the proper pin numbers for your engine arrangement.
2. Connect from the Engine Room -Battery Bus Bar to the Display -Battery Bus Bar at Station 1 using 12 AWG wire minimum.
3. Connect from the Engine Room -Battery Bus Bar to the Display -Battery Bus Bar at Station 2 using 12 AWG wire minimum.

CAT Data Link Connections
NOTE: Avoid splicing or soldering wire connections. All connections should be terminated at terminal strips to ensure engine and communication systems reliability.
NOTE: Refer to the table below for the proper pin numbers for your engine arrangement.
Engine Room Connections
1. Connect STBD and PORT Customer Connector CAT Data Link+ to the Engine Room Data Bus Terminal Strip #1 using 143-5018 CAT Data Link cable.
2. Connect the STBD and PORT Customer Connector CAT Data Link- to the Engine Room Data Bus Terminal Strip #1 using 143-5018 CAT Data Link cable.
NOTE: The Engine Room Data Bus Terminal Strip #1 should be located as close as possible to the J3 Customer Connector to minimize the length of the data cable.
Figure 13 - Engine Room Connections
Engine Room To Bridge Connections
3. Connect CAT Data Link- from the Engine Room Data Bus Terminal Strip #1 to the Bridge Data Bus Terminal Strip #2 using 143-5018 Cat Data Link cable.
4. Connect CAT Data Link+ from the Engine Room Data Bus Terminal Strip #1 to the Bridge Data Bus Terminal Strip #2 using 143-5018 CAT Data Link cable.
Figure 14 - Engine Room To Bridge Connections
NOTE: Proper wiring of the Cat Data Link System is essential for proper display operation. The CAT Data Link System should use 143-5018 CAT Data Link cable. The installation should use a dedicated terminal strip for the CAT Data Link connections. This terminal strip should be located to minimize the length of the CAT Data Link data wire run. There should be only one set of twisted pair data wires that run to the bridge displays. If a second station is to utilize a Caterpillar display group, then data wires should be installed from the engine room terminal strip to the first station and continued from the first station to the second station.
Data Loop
Improper wiring of the Cat Data Link System will result in a Data Loop that will cause the CAT Data Link system to function improperly.
Remote Service Tool Connector
NOTE: The optional Electronic Service Tool Connection is not recommended on 3400C High Performance Marine Engines.
NOTE: An Electronic Service Tool will operate with the engine running, or with the engine OFF, keyswitch ON.
