2 Technical TD E 1 System description The Eaton esm hardware system is designed with a master module that connects to other ECUs via SAE J1939 CAN 2.0b. The master communicates with Eaton expansion modules using LIN 2.0. Each master can support up to seven expansion modules. Features Center indicator has up to four colors for status information Long life switches: 500,000+ cycles Easy address assignment Immune to SAE J1455 and J1113 power disturbances Emissions to CISPR 25 Class 4 J1939 CAN 2.0b messaging LIN 2.0/SAE J2602 communication between expansion modules Keypad and rocker modules can be mixed in a single system 2.1 Lighting All lighting is controlled by CANbus message. Off On Slow flash 1 Hz Fast flash 2 Hz Short flash 200 ms On/800 ms Off Long flash 800 ms On/200 ms Off Wake/Sleep flash 250 ms On/4000 ms Off Indicator lighting Indicator lighting is controlled by CANbus message (see 12.7 Indicator lighting on page 10). Icon lighting Icon lighting is controlled by CANbus message (see 12.8 Icon LED control on page 10). Night mode lighting Night mode turns all icon backlights On and Off with a single message. The master and all expansion connected to it respond to the single message. Standard icon lighting commands will override the Night Mode command (see 12.2 System message on page 8). Wake/sleep flash This command will flash the indicator during wake and sleep modes. It can be used to indicate that a vehicle theft system is active on a parked vehicle. Byte 8 must equal 10h when turning this On or Off (see 12.2 System message on page 8). 2 Rocker switch modules Rocker switch modules have two laser etched icons and one indicator for each switch. Icons have one backlight color and indicators can have up to four colors. The rockers have 11 combinations of momentary and sustained action. Indicators and icons do not retain their state during power off or sleep mode and must be commanded On when the module enters wake mode. 2.2 Rocker circuits The following circuits are available: Three- Position On On On Double On On On On Top Sustain Sustain Middle Sustain Sustain Sustain Sustain Bottom Sustain Sustain Part # Two- Position On On Up Down Top Sustain Sustain Middle None None None Bottom Sustain Sustain Part # Half Action Half Up Half Down Half Up Half Down Top Sustain None None Middle Sustain Sustain Sustain Sustain Bottom None Sustain None Part # No Action Indicator Dummy Plug Part #

The modules are put into sleep mode by CAN message. Sleep mode reduces current draw on the battery. During sleep mode: The master monitors the CANbus for wake from sleep message The master monitors itself and expansion modules for switch press The lighting on all modules is off except Indicators that are in alarm flash mode No CAN messages are broadcast 3.3 Wake on CAN message A Wake Command on the CANbus will Wake the system from sleep (see 12.2 System message on page 8). 3.4 Wake on switch press Switches can be individually programmed to wake the system when they are pressed. This lets the system designer choose specific functions that are allowed to wake the system (see 12.6 Wake system on switch press on page 10). Example: Headlight switch can wake the system to ensure that they could be turned on without the key but the mirror heat could not be enabled because the function should only be active if the vehicle is running. The master module has a digital output that can be programmed to turn on for four seconds when the wake on switch press occurs (see 6 Master module digital output on page 5). 4 Switch reporting The master module broadcasts the status of its switches and the expansion switch modules on the CANbus. When a switch is pressed the master will send an immediate CANbus message. When no switch has been pressed for one second the master will broadcast the switch state of each module at one second intervals (see 12.5 Switch press messages on page 9). 5 Module address Each module has an address that is used to identify it on the data bus. Master modules have a CAN address that the other controllers on the vehicle use to communicate with it. Expansion modules have a local address that the master uses to communicate with them. Expansion modules do not have a CAN address. 5.1 Master address Master switch modules can have one of eight addresses. Master addresses are in the proprietary space of J1939 and have the following possible header values. Eaton Master Message Header Eaton Master Message Header 1 18h FFh A1h A1h 5 18h FFh A5h A5h 2 18h FFh A2h A2h 6 18h FFh A6h A6h 3 18h FFh A3h A3h 7 18h FFh A7h A7h 4 18h FFh A4h A4h 8 18h FFh A8h A8h 5.2 Master addressing Jumpers in the wire harness set the address as follows. Terminal Pins Connected Address Terminal Pins Connected 6-7 A1h 7-9 A5h 6-8 A2h 8-9 A6h 6-9 A3h 6-7, 8-9 A7h 7-8 A4h 6-8, 7-9 A8h 5.3 Expansion module address Address Expansion modules can have an address between 1 and 7. The module can be purchased with an address or it can be assigned by the customer. The factory default address is FFh. With this address the module LEDs will be flashing, it will not broadcast any messages or respond to LED commands until it is assigned an address between 1 and Expansion switch press addressing This assigns an address to a module by pressing a switch on each module. First the master is put into Address Assignment mode and then given the configuration of types of expansion modules that will be connected to it. A button on the master is pressed. Expansion modules are pressed in order of their addresses. First expansion pressed is address 1, second module pressed is address 2 and so on. If there are gaps in the configuration such as (exp 1) (exp 2) (exp4) the master will automatically skip from (exp 2) to (exp 4). The master stores this configuration in permanent memory. It is used to check that all expansions are active during operation and report a fault if a module is missing. The master must go through this process or it will report that no modules are connected to it. Steps of address claim process All steps must be followed. If there is no expansion 7 in the system, Step 3 must still be completed. 1. Send start of address claim CAN message (see 12.2 System message on page 8). 2. Send first configuration message (see 12.4 Module types on master on page 9). 4

5 Technical TD E 3. Send second configuration message (see 12.4 Module types on master on page 9). Note: Above three CAN messages must be received in order and with a delay between 20 ms < delay < 1 sec (500 ms is recommended). 4. Indicators on master will start flashing. 5. Press a switch on master, indicators on master stop flashing and remain continuous On. Indicators on all expansion switch modules start flashing. 6. Press a switch on the module that is to have address 1. Indicators on this module stop flashing and remain continuous On, while Indicators on all other expansion switch modules keep flashing. 7. Press a switch on the module that is to have next address, Indicators on this module will stop flashing and remain continuous On, while all other expansion switch modules keeps flashing their indicators. 8. Repeat above procedure until all modules in the network are assigned an address. After switch press on last module, master will send Address Assignment Complete message (12h 00h 00h 00h 00h 00h 00h 00h) and indicators on all modules will flash for 5 seconds. 9. If a fault occurs: Master will flash indicators and broadcast a message indicating cause of the fault (see 12.1 Diagnostic fault messages on page 8) All expansion switch modules will be assigned address FFh The master must complete a successful expansion address claim to clear the fault 5.5 Address assignment faults When the master has a fault during Set Expansion Address by Switch Press it will send a fault message on the CANbus (see 12.1 Diagnostic fault messages on page 8). Once in fault mode the master will flash indicator LEDs. It will need to complete a correct expansion switch press addressing cycle to clear the fault. The master will enter fault mode for any of the following reasons. Exceed 5 minutes between start of address assignment and the press of a rocker on the master. This is done to signal that the process was properly started but the operator never pressed any switch Exceed 1 minute to press a rocker on all modules Missing expansion modules Too many expansion modules Mismatch between received configuration and types of expansion modules connected to master 5.6 Expansion address by CAN message The expansion address can be set by sending a single command on the CANbus. All expansions connected to the master will take this address (see Special function messages on page 11). 5.7 Indicator module address assignment Indicator rockers that do not move up and down are available. If an expansion module has indicator rockers in all positions it will need to have the address assigned using a CAN message because no switch can be pressed for a switch press address assignment cycle (see Special function messages on page 11). 5.8 Master service swap Master service swap allows a master to be swapped into a fully configured system and automatically set a correct expansion module configuration. When power is first applied to the master it automatically sends a request for configuration on the CANbus. If another ECU on the CANbus provides a complete configuration the master will overwrite the configuration it had with the configuration that it just received. To use this feature the following must occur at cold boot: At power up of the module, the master automatically sends a Request for System Configuration (see 12.3 Status message on page 9) Master must receive system configuration within 500 ms of the request Vehicle ECU Send First Configuration Message (see 12.4 Module types on master on page 9) Vehicle ECU Send Second Configuration Message (see 12.4 Module types on master on page 9) This is useful for swapping masters between vehicles without the need to run an address assignment cycle. 5.9 Expansion service swap A single expansion module can be swapped into a system and the master will automatically give the proper address to that module. The master will do this without CANbus command. The module that is being swapped in must have address FFh. Only one module can be swapped. All other modules must be properly configured and connected for the master to set the address. If the master had three expansions connected to it and the second module in the chain was removed the master would see that two expansions are missing. If a factory default module were now connected to the first module the master would do nothing. When the third module is connected the second the master will now check to see if the expansions have two valid addresses and one factory default. If that is the case address FFh will automatically be assigned the address of the device that is missing. Only one module can be replaced at a time. If two modules were replaced the master would not know which address to give to the FFh modules. This is useful in a service setting where a module can be replaced without the need to run a complete address assignment cycle. To reset an expansion module address to FFh use Set Expansion Address by CAN Message (see Special function messages on page 11). 6 Master module digital output The master module has a digital output that can be configured two ways. This is set using the 12.2 System message on page 8. Active for four seconds when Wake on button press occurs Active when commanded by CAN message (see Digital output control on page 11) When configured for control by CAN message use the digital output control (see Digital output control on page 11). 5

6 Technical TD E 7 Watchdog The master and expansion modules implement a hardware watchdog. If the code stops executing properly the system will reset and report the fault using diagnostic fault message (see 12.1 Diagnostic fault messages on page 8). 8 CAN controller diagnostics The master module has a basic CAN diagnostics feature. The master module stores the counts of the CAN controller state changes. The master module sends the counts when it receives a request (see 12.2 System message on page 8). 9 Part number and revision information Each device contains manufacturing, part number and revision information. This information is available by sending a CAN message request. The information is stored in ASCII format. The following information about the manufacture of the product can be retrieved by using CAN message. Hardware part number: 12 characters Hardware version number: 2 characters Software part number: 32 characters Software version number: 2 characters Manufacturing date of PCB: 5 characters PCB serial number: 10 characters Eaton build date information (final assembly manufacture date): 5 characters Catalog number (finished assembly part number): 20 characters The data in these messages is ordered such that char1 is the left most character in the string. The undefined characters are stored as an ASCII space (20h). The request message: See 12.2 System message on page 8. The response message: See 12.3 Status message on page System faults The master will report faults in the system on the CANbus (see 12.1 Diagnostic fault messages on page 8). 11 Message structure Eaton messages are J1939 CAN messages and they follow the CAN 2.0b message specification. These messages have a 29 bit header and 8 bytes of data. The header identifies where the information is coming from and where it is going. The headers used by the Eaton system are in the proprietary space of J1939. The first byte of data defines the type of information in the other seven bytes Messages sent to Eaton master Priority PDU Format PDU Specific Source Address 18h EFh A1h A8h Not filtered 08 Message Length Transmission rate: On demand length: 8 page: 0 PDU format: 239 (EF) PDU specific: 161 = Master 1 (A1h) 162 = Master 2 (A2h) 163 = Master 3 (A3h) 164 = Master 4 (A4h) 165 = Master 5 (A5h) 166 = Master 6 (A6h) 167 = Master 7 (A7h) 168 = Master 8 (A8h) Default priority: 6 PGN: 61,345 = Master 1 (EFh A1h) 61,346 = Master 2 (EFh A2h) 61,347 = Master 3 (EFh A3h) 61,348 = Master 4 (EFh A4h) 61,349 = Master 5 (EFh A5h) 61,350 = Master 6 (EFh A6h) 61,351 = Master 7 (EFh A7h) 61,352 = Master 8 (EFh A8h) Source address: Not filtered Example: A controller sending information to an Eaton master with PDU specific address = A1h it should use the following CAN header: 18h EFh A1h XXh 08h Messages sent by Eaton master Priority PDU Format PDU Specific Source Address 18h FFh A1h A8h Same as PDU Specific Transmission rate: On demand or on switch press length: 8 page: 0 PDU format: 255 (FFh) PDU specific: 161 = Master 1 (A1h) 162 = Master 2 (A2h) 163 = Master 3 (A3h) 164 = Master 4 (A4h) 165 = Master 5 (A5h) 166 = Master 6 (A6h) 167 = Master 7 (A7h) 168 = Master 8 (A8h) Default priority: 6 PGN: 65,445 = Master 1 (FFh A1h) 65,446 = Master 2 (FFh A2h) 65,447 = Master 3 (FFh A3h) 65,448 = Master 4 (FFh A4h) 65,449 = Master 5 (FFh A5h) 65,450 = Master 6 (FFh A6h) 65,451 = Master 7 (FFh A7h) 65,452 = Master 8 (FFh A8h) Source address: Same as PDU specific Message Length 08 6

This number typically is 8. J1939 uses a Parameter Group Number (PGN). This is comprised of the: byte 1: PDU format byte 2: PDU specific It does not include the priority or source address The PGN for messages sent to Eaton master 1 is 61,345 (EFh A1h) The PGN for messages from the Eaton master 1 is 65,441 (FFh A1h) The 29-bit identifier comprises the following sub-fields: Priority (3 bits), extended data page (EDP, 1 bit), data page (DP, 1 bit), PDU format (PF, 8 bits), PDU specific (PS, 8 bits), and source address (SA, 8 bits). The source address field ensures unique CAN identifiers, so no two nodes can ever transmit the same CAN identifier. In the beginning, J1939 grouped several parameters (signals) together into a Parameter Group (PG). Each PG was then assigned a Parameter Group Number its PGN. The PGN identifier contains the EDP, DP PF and PS fields. This structure has since caused some confusion with regard to PDU1-type (destination-specific) messages. Since the PDU-specific (group extension) field becomes the destination address in a PDU1 message, the question arose if the PGN changes, it does not. The PGN is a static number referring to the data being transmitted and should be considered independently of the CAN identifier portion of message The data portion of the message is broken into two pieces; the data descriptor and the message data. Byte 1 is the data descriptor which identifies the type of data the message carries. The 7 remaining data bytes carry the information. Using the data descriptor allows a single J1939 address to handle all of the message needs for a master and its expansion modules. This is very important for devices in the proprietary address range of J1939 because the number of addresses is limited and the more addresses a single device uses the greater the chance it will have an address conflict with another device. Bytes descriptor The following table describes the type of data carried by each value of the data descriptor byte.

Refer to customer drawing for colors. These messages set an Indicator On, Off or flashing while in wake mode. When the system enters sleep mode these values will be cleared to Off and will only turn On when they are commanded on in wake mode. 0000b = Off 0001b = 100% On 0010b = 1 Hz 500 ms On/500 ms Off 0011b = 2 Hz 250 ms On/250 ms Off 0100b = 200 ms On/800 ms Off 0101b = 800 ms On/200 ms Off 0110b = Wake sleep flash 250 ms On/4000 ms Off Wake sleep flash This command will cause the Indicator to flash during both wake and sleep modes. It is not cleared when the system enters sleep mode as the regular flash values are. Byte 8 must be set to 0x10 to turn wake sleep flash On or Off. This could be used for an indicator that you want to have flashing when the vehicle is off to show that an alarm system is active.

12 Technical TD E 14 Troubleshooting Problem No CAN messages Expansion modules are flashing New expansion modules are flashing and they are not sending switch change messages Expansion modules do not send switch info after they were given an address using special function message Can t complete a address claim by switch press with an indicator module After using special function message to set address of one module, all the modules have that address Do I need to set up a separate software routine to start set expansion address by switch press LEDs are changing randomly Master is stuck with all LEDs on and it will not report expansion modules Possible Solution Use 29 bit CAN 2.0b messages Check CAN header is using EF: Example is 18 EF A1 A1 08 Check the resistance from CAN (+) to CAN ( ) is 60 ohms Check CAN (+) and CAN ( ) are not crossed Check that the message filter for the display will pass messages with the header for the master. Example: If there is only an acceptance filter for engine speed the Eaton switch messages would not be shown. Use extended message format. This is 29 bit. Standard message format is 11 bit and it will not work. New expansion modules do not have an address. When a module has no address it flashes to indicate that. Any time the address is set to FFh, the module will do this. New modules do not have an address. Modules that do not have an address will not send switch messages. Expansion modules that have been assigned an address by special function message can be used to replace an expansion that was already in the system. The master must know which modules on attached to it. The only way it knows the configuration is for it to go through a set expansion address by switch press one time. After it gets the configuration expansion modules that have addresses that were in the configuration can be replaced. Because modules that have 3 indicators have no button that can be pressed they must first be configured as an indicator module. Use the special function message to set the address of the module. Be sure to set byte 4 = 1. The indicator module can be the only module connected to the master when this command is sent. When the master sends a special function message to set the address of a module, all expansion modules connected to the master will take that address. If you want only one module to have the address, it can be the only device connected to the master. The timing for the three messages that the master needs to receive is not too tight. They just need to be within 1 second of each other. If you can manually send a message you should be able to send three messages with less than one second between them. Check the traffic on the CANbus to see if some other device is using the same address as the master. When a master starts a set expansion address by switch press and it faults, it will turn on an LED on each Indicator and do nothing else. You need to run it through a complete address cycle. You may want to connect just the master, send a configuration that has only the master and it will then clear the fault. Status LED set for wake/sleep flash will not stop To clear a wake sleep flash byte 8 of the message must be 10h. Messages with byte 1 = 10h keep popping up If a master has a configuration that includes a module that is not plugged in, it will send missing module fault messages to let you know it is not there. Cannot set address of indicator module Indicator modules must have their address set by special function message.
