2 Multi-Station Control Installation Guide MSCS OVERVIEW ETP is an optional component The ETP controls trolling operations through an electrical signal to the trolling valve Calculates shaft speed with shaft speed sensor J1939 Communications to and from ETP, ECU, and displays Drive circuit to Port gear for Ahead, Neutral, or Astern positions 2 Primary and 2 Secondary positive and minus battery inputs to the PCP When the Backup Panel activates, the PCP sends the throttle signal to the ECU on the ECU Secondary Throttle input Anti-stall strategy is disabled The ICH or CSP reads in the movement (desired engine speed) from the control head levers or button actuation The ICH or CSP then sends a data link message via the proprietary CAN data link, to the PCP This is a data link message, not a PWM signal or a switched input The ICH could be replaced with a CSP, control head and a button panel Switched inputs and throttle PWM signal to Port ECU MJB is used to route the various signals and data link communications to their destinations J1939 Displays Not used with MSCS II The Multi Station Control System (MSCS) is available in two versions The full version MSCS and reduced component version MSCS II This document covers the installation of both versions with most examples being of MSCS MSCS II has the same functionality as MSCS with these exceptions: 1 No backup panel capability 5 Smaller diameter cabling 2 No Marine Junction Box (MJB) 6 Installer must provide power, ground, and keyswitch 3 Two control station limit distribution to the 70-pin customer connection and PCP 4 Three display station limit

4 Multi-Station Control Installation Guide J1939 CAN NETWORK A J1939 CAN network is required for each engine to operate the MSCS These J1939 CAN networks must conform to the J1939-71 standard for installation and topology Improper installation can cause intermittent or complete failure of the MSCS See typical J1939 CAN network layouts The J1939 CAN networks must be installed in a trunk conﬁguration of 40 meters or less with 120 ohm terminating resistor installed at the far ends Drops off of this trunk must be 1 meter or less

6 Multi-Station Control Installation Guide The Powertrain Control Processor (PCP) is the main control processor of the Multi-Station Control System (MSCS) The PCP is responsible for the interface between the control stations, the engine Electronic Control Unit (ECU), and the transmission solenoids POWERTRAIN CONTROL PROCESSOR 219-8020 MSCS II 311-8400 POWERTRAIN CONTROL PROCESSOR

Multi-Station Control Installation Guide 7 The master station and control station CAN data links are used to communicate with the control stations, either Integrated Control Head or Control Station Processor utilizing the proprietary communication data link There may be only one control station on the master control station data link and up to seven control stations on the control station data link MSCS II may have only one control station on the control station data link The control stations will communicate with the PCP the throttle position (0 – 100%), gear select (ahead, neutral, astern), and button states, via the proprietary CAN data link There are five buttons available at the control station; Station Active, Throttle Sync, Slow Vessel Mode, Gear Lockout, and Troll The Troll feature is an optional feature depending upon the presence of an Electronic Troll Processor (ETP) Each button has a corresponding indicator lamp; the PCP will turn on each lamp via the proprietary data link when the button function is active The port and starboard SAE J1939 communication links are the public data links used for serial data communications with the engine ECU, Marine Power Displays, Electronic Troll Processor, and Cat ® ET or WinFlash service tools Each data link is separate and independent from the other POWERTRAIN CONTROL PROCESSOR

8 Multi-Station Control Installation Guide Engine speed is controlled via a PWM signal from the PCP to the ECU throttle input Speed is controlled linearly from low idle at 0% throttle to max engine speed or Wide Open Throttle (WOT) at 100% throttle The “Backup System Active” is a digital signal from the backup processor that indicates throttle and gear shift control by the PCP is no longer active When the backup system is active a diagnostic alarm will be activated The alarm can be acknowledged and silenced by pressing the Marine Power Display (MPD) alarm silence button Each control station provides engine throttle control and transmission gear control through the use of a mechanical lever (this may be separate throttle and gear levers or a combined throttle/gear lever) Additional operator control/feedback is accomplished via input buttons and indicator lamps for station activation, engine throttle sync, slow vessel mode, troll activation (optional), and gear lockout This data is transmitted to the PCP by the active station via the master control station CAN data link or the control station CAN data link POWERTRAIN CONTROL PROCESSOR

Multi-Station Control Installation Guide 9 The PCP must be mounted in a location that is free from direct exposure to moisture such as an inside bulkhead wall in the engine room For ease of installation and to reduce wire lengths the PCP should be mounted close to the Marine Junction Box (MJB) Mount the PCP on the bulkhead wall so that the Throttle/J1939 and transmission connectors are pointing down MOUNTING DIMENSIONS MOUNTING INSTRUCTIONS PCP Power 12-pin connector STBD Transmission 8-pin connector Port ECM/ETP 12-pin connector STBD ECM/ETP 12-pin connector Port Transmission 8-pin connector POWERTRAIN CONTROL PROCESSOR
