CAN Annunciator Software Configuration
The CAN annunciator is field-programmable using Cat ET. The annunciator is also flash programmable to update software using Cat ET.
The service tool software must be installed on a Windows PC. The communication adapter must be connected between the PC and the CAN 2 accessory data link on which the target CAN 2 annunciator is connected.
The CAN annunciator can be configured to both initiate and respond to an event acknowledge message over the CAN accessory data link. If the set point is enabled, the CAN annunciator events may be acknowledged locally on the CAN annunciator. Acknowledge by pressing the alarm acknowledge button or remotely by pressing the alarm acknowledge button on the EMCP 4. The event can also be acknowledged by pressing the acknowledge button on another CAN annunciator configured for global acknowledge that is on the same data link. Acknowledging events also silences the horn.
The default setting for the set point is "disabled", however, the set point can be enabled from the configuration tool within Cat ET.
Electronic Control Unit (ECU) Instance Number
The module description will indicate a number that identifies the CAN annunciator uniquely from any other CAN annunciator modules on the accessory CAN data link.
The number is called the ECU instance and is programmable.
The service tool configuration screen identifies the serial number of the CAN annunciator that is connected. The serial number identity is important in matching the desired ECU instance to the actual hardware.
Note: If two CAN annunciators on the same communications network are programmed for the same ECU instance number, neither will communicate.

There are three possible selections for trigger condition:
Specific event - Used to assign an LED pair to a specific data link parameter, such as oil pressure, engine speed, or coolant temperature. The desired parameter must be chosen in the "Suspect Parameter Number" column.
General event - is used to assign an LED pair as a general alarm or shutdown indicator. When configured as general event, the LED will not be assigned to a particular parameter. The LED will respond to any event with a severity level chosen in the "Severity Level" column, regardless of the suspect parameter number.
Disabled - Is used to disable the LED pair. When disabled is selected, the other three parameters cannot be changed.
Severity level defines which types of events the LED pair will react to. Selections that begin with condition exists will respond to CAN event messages for Failure Mode Identifier (FMI) 31 condition exists.
For example, LED pair #2 is configured for "Condition Exists, Red On, Other Not Used, Horn On" with SPN 190 (Emergency Stop Active). The example means that when the annunciator received a CAN message indicating emergency stop with FMI 31, the red LED will turn on and the horn will also turn on.
"Other Not Used" indicates that the other LED color in the pair is never used.
"Green Off" (for example) indicates that the green LED lights when the condition chosen for this LED pair is not active.
Most severity level selections imply CAN Failure Mode Identifier (FMI) codes:
- Condition exists that is equivalent to FMI 31
- High warning can be FMI 15 or FMI 16
- Low warning can be FMI 17 or FMI 18
- High shutdown is equivalent to FMI 0
- Low shutdown is equivalent to FMI 1
- High or low shutdown is equivalent to FMI 0 or FMI 1
Since the FMI codes are implied by this column, the FMI column is grayed out for any of these selections.
The only option that will allow an FMI to be configured is specific diagnostic. Table 5 shows all available FMI codes.

A red/green pair located at the bottom of the RS-485 annunciator, is used to report module/network status. The various states indicated are explained in Illustration 20 and Table 9.
Illustration 20 | g03515392 |
Red/green module status LEDs |
Behavior | Explanation |
---|---|
Red solid | Datalink diagnostic. For example: the module is wired wrong (data link), or no terminating resistor. |
Green solid | Data is being received from the EMCP 4 |
Green flashing | Loss of communication |
Red/Green alternating | No application software loaded, or alarm group selection mode is active |
The annunciator supports a lamp test function from a button press on the EMCP 4.
The lamp test function cycles continuously through two test modes while pressing and holding in the lamp test button. The first mode is a column test mode. The left column of LEDs will be lit for one second while the right column is off. Then the right column of LEDs will be lit for one second, while the left column is off. The procedure will occur twice. During the second run of the test mode (during the first cycle only), the horn will be on.
The second test mode is an individual LED test mode. In the second test mode, the LEDs will light one at a time. The LEDs will light starting from the top left LED, down to the left-hand module status LED. The LEDs will begin to light on the right-hand module status LED, then up to the top right LED. Each LED will be lit for 1/2 second, after which the LED will turn off and the next LED will be lit. At the completion of this test mode, the cycle will restart with the first test mode. However, on subsequent runs of the first test mode, the horn will not turn on.
The RS-485 annunciator returns to normal operation once the lamp test button is released.
The RS-485 annunciator supports an acknowledge event/silence horn function from a button press on the RS-485 annunciator or from the EMCP 4. Both cases have different behavior and are outlined below.
When an active event is received from the EMCP 4 and is acknowledged locally with a button press on the RS-485 annunciator module, any flashing LED tied to that event will stop flashing and maintain a steady illumination and the horn will be silenced.
Note: Only the local RS-485 annunciator module that acknowledges the active event will change the state of flashing LEDs and silence the horn. The acknowledge signal sent out by the RS-485 is not broadcast to any other units on the RS-485 annunciator data link.
An active event is transmitted to the RS-485 Annunciator module (or modules) when both of the following conditions exist:
- An active event is received from the EMCP 4
- An active event is acknowledged globally with a button press on the EMCP 4 controller
Any flashing LED tied to that event will stop flashing and maintain a steady illumination and the horn will be silenced.
Note: The EMCP 4 may acknowledge active events on multiple RS-485 annunciators simultaneously.
The horn silence/acknowledge function will cause the local horn to be silenced until another event causes an LED to be activated.
RS-485 Annunciator Alarm Groups
The RS-485 annunciator supports four different alarm groups. Alarm group 01, 02, 03, and alarm group 04. Two of the alarm groups, 03 and 04, are fixed, therefore cannot be configured. Two alarm groups, 01 and 02, are reserved for custom event settings. Alarm groups 01 and 02 can be configured.
Selecting which of the four alarm groups to configure the RS-485 annunciator is determined by the film that is placed on the front left panel. The alarm groups and the events that make up the films for each of the alarm groups are detailed in the tables below. Configuring the RS-485 annunciator to one of the four alarm groups is accomplished through the front panel of the RS-485 annunciator. For more information, refer to the following "Alarm Group Selection Mode (AGSM)" section.
Alarm Group Selection Mode (AGSM)
The RS-485 annunciator supports the "Alarm Group Selection Mode" (AGSM). The AGSM can configure the RS-485 annunciator to monitor a predetermined set of 32 events. The events are communicated by the EMCP 4 through the dedicated RS-485 annunciator data link.
Alarm group selection and assignment are determined by the desired functions of the RS-485 annunciator. Selection and assignment are for custom annunciators or annunciators that cannot be configured. The film that is placed on the front left panel that reflects the predefined events monitored by the RS-485 annunciator. When in AGSM, the top first four rows of LEDs will indicate which alarm group the RS-485 annunciator has been assigned to. The annunciator is indicated by powering on both LEDs in each row. Row 1 is for alarm group 01, row 2 is for alarm group 02, row 3 is for alarm group 03, and row 4 is for alarm group 04.
Note: The RS-485 annunciator will be pre-programmed to alarm group 04.
The RS-485 annunciator will continue to communicate to the EMCP 4 while in AGSM. Events received from the EMCP 4, while in AGSM, will not be annunciated until AGSM has been exited. Also, the event will be annunciated only if the event that is received is an event in the selected alarm group.
Once the RS-485 annunciator has successfully been assigned to an alarm group, the RS-485 annunciator shall receive and process any event transmitted. The event is transmitted from the EMCP 4 to the assigned alarm group without power cycling the module.
The network status LEDs will alternate flashing at a 2 Hz rate at all times while in AGSM.
The RS-485 annunciator will enter AGSM by pressing the two buttons on the front panel of the RS-485 annunciator. Press the lamp test and alarm acknowledge for 3 seconds. The RS-485 annunciator will acknowledge entrance of AGSM by flashing the top four rows of LEDs 4 times at a 1 second rate.
After the 3 second period has timed out, the row representing the currently assigned alarm group address will be powered on. The remaining 11 rows of LEDs will not be powered on. Refer to Table 10.
Row | Column 1 | Column 2 |
---|---|---|
1 | Solid if assigned to alarm group 01, else off | Solid if selected to alarm group 01, else off |
2 | Solid if assigned to alarm group 02, else off | Solid if selected to alarm group 02, else off |
3 | Solid if assigned to alarm group 03, else off | Solid if selected to alarm group 03, else off |
4 | Solid if assigned to alarm group 04, else off | Solid if selected to alarm group 04, else off |

11 | Off | Off |
12 | Off | Off |
13 | Off | Off |
14 | Off | Off |
15 | Off | Off |
16 | Off | Off |
Configuring or Selecting Alarm Group Address
While the RS-485 annunciator is still in AGSM, the annunciator will cycle through the four alarm groups. Press one of the two buttons on the front panel to cause the annunciator to cycle through the four alarm groups. Pressing the lamp test button will cycle up through the four alarm groups. Pressing the alarm acknowledge button will cycle down through the four alarm groups.
Upon reaching alarm group 04 (row 4), while cycling down through the alarm groups with the alarm acknowledge button, an additional alarm acknowledge button press will bring the selection to alarm group 01 (row 1). Upon reaching the alarm group 01 (row 1) while cycling up through the alarm groups with the lamp test button, an additional lamp test button press will bring the selection to alarm group 04 (row 4).
When selecting a new alarm group address, the left column (red LED) will represent the previously configured alarm group selection. The right column (amber LED) will represent the currently selected alarm group. When AGSM is exited, the currently selected register address will be configured as the new alarm group.
The annunciator will exit AGSM under two possible conditions:
- A time-out period without any button presses
- Pressing and holding two buttons (alarm acknowledge and lamp test buttons) for 3 seconds
After a period of 15 seconds without any button presses, the RS-485 annunciator will automatically exit AGSM. The RS-485 annunciator will disregard any changes made to the alarm group selection. The RS-485 annunciator will remain configured to the alarm group prior to entering AGSM.
When an alarm group selection has been made and the lamp test and alarm acknowledge pressed and held for 3 seconds, the RS-485 annunciator will update the current configured alarm group. Also, the RS-485 annunciator will update the current selected alarm group and then exit AGSM.
After exiting AGSM under either one of the two exit conditions listed, the RS-485 annunciator will flash all 16 rows of LEDs for 3 seconds. The RS-485 annunciator will enter regular annunciation mode.
RS-485 Annunciator Custom Alarm Group Configuration
The RS-485 annunciator is field-programmable by the EMCP 4 via Cat ET when configured for alarm groups 01 and 02. Alarm groups 01 and 02 support customization of the 32 events for the 16 LEDs.
The service tool software must be installed on a Windows based PC. The communication adapter must be connected between the PC and the CAN primary data link on which the target EMCP 4 is connected.
When Cat ET is communicating, the EMCP 4 shall be selected as the target module. Use the following to access the RS-485 annunciator configuration dialog.
- Located at the top of Cat ET is the tool bar, click on the "Service" tab.
- From the drop-down menu, click "RS-485 Annunciator".
The RS-485 annunciator configuration screen will be displayed with the alarm group select at the top left of the screen. There are two possible selections for alarm groups: #1 and #2.
To configure the RS-485 annunciator LEDs, select each of the LEDs individually. With the selected led window displayed the initial selection is for trigger condition. There are three possible selections for trigger condition: specific event, general event, and disabled.
Specific event - Used to assign an LED pair to a specific data link parameter, such as oil pressure, engine speed, and coolant temperature. The desired parameter must be chosen in the "Suspect Parameter Number" column.
General event - Used to assign an LED pair as a general alarm or shutdown indicator. When configured as general event, the LED will not be assigned to a particular parameter. The LED will respond to any event with a severity level chosen in the severity level column, regardless of the suspect parameter number. When a general event is selected, the suspect parameter number cannot be changed.
Disabled - Used to disable the LED pair. When the disabled option is selected, the other three parameters cannot be changed.
Severity level defines which types of events the LED pair will react to. Selections that begin with condition exists will respond to can event messages for Failure Mode Identifier (FMI) 31 condition exists.
For example, LED pair #1 is configured for "Condition Exists, Red On, Other Not Used, Horn On" with SPN 190 (emergency stop active). That is, when the RS-485 annunciator receives a data from the EMCP 4 over the RS-485 annunciator data link indicating emergency stop with FMI 31, the red LED will turn on and the horn will also turn on.
Other not used indicates that the other LED color in the pair is never used.
Green off (for example) indicates that the green LED lights when the condition chosen for this LED pair is not active.
Most severity level selections imply "Failure Mode Identifier" (FMI) codes:
- Condition exists that is equivalent to FMI 31
- High warning can be FMI 15 or FMI 16
- Low warning can be FMI 17 or FMI 18
- High shutdown is equivalent to FMI 0
- Low shutdown is equivalent to FMI 1
- High or low shutdown is equivalent to FMI 0 or FMI 1
Since the FMI codes are implied by the choice made in the "Severity Level" column, the FMI column is grayed out for any of the selections.
The only option that will allow a specific FMI to be configured is specific diagnostic.
The "Suspect Parameter Number" column is used to select one of the listed SPN's in the drop-down menu or type in a specific SPN number for an spn that may not be listed in the drop-down menu for the parameter assigned to the led pair. Most supported SPN's can be selected from the list.
When configuring the RS-485 annunciator for "Engine Running", special consideration must be taken to trigger the event. The event can be triggered in a variety of ways. A selection of "Engine Running" trigger conditions is provided in Cat ET and on the EMCP display.

Illustration 22 | g03515703 |
EMCP4.2 Display engine running conditions configuration screen |
The "Engine Running Conditions" are logically combined together such that any selection will activate the condition and consist of the following options:
- Custom event digital input (SPN 701)
- Engine running (based on engine overview state with non-zero engine speed)
- V/Hz within limits (unit is close to rated voltage and rated frequency)
- Engine running at rated speed (Engine running, not in Idle, not in cool down)
For using the "Custom Event Digital Input" trigger condition, the SPN shall be configured for "Auxiliary I/O #1" (SPN 701). The SPN shall have a severity level configured for any one of the condition met set points
Digital input #1 shall be physically wired to the active status signal that is to be used to trigger this programmed LED. If digital input #1 is only to be based upon the status of the generator set, controlled by the EMCP, then only specified outputs can be used. The following are examples of what outputs can be used.
- Relay output #2
- Fuel control relay
- Engine starting initiated for common engine interface generator sets on the EMCP 4
The fuel control relay or engine start initiated active status signal is continually active only while the engine is in running.
Alarm Group #3 has LED #15 pre-configured for "Auxiliary I/O #1". Alarm Group #3 with LED #15 requires the actions above to trigger an engine running event on the RS-485 annunciator.

The RS-485 annunciator can be configured for four alarm groups. Two of the alarm groups are fixed and two groups can be configured. Selection of which alarm group is used shall be accomplished by using the front panel of the RS-485 annunciator module. Refer to the preceding "Alarm Group Selection Mode" (AGSM) section that explains the selection process. Details of the pre-configured events for each of the alarm groups are outlined below:
- Alarm Group # 1 (Custom 1 that can be configured) - Film # 1 (refer to Table 11) and custom film
- Alarm Group # 2 (Custom 2 that can be configured) - Film # 1 (refer to Table 11) and custom film
- Alarm Group # 3 (Fixed) - Film # 1 (refer to Table 11)
- Alarm Group # 4 (Fixed) - Film # 2, or Film # 3 (refer to Table 12 and Table 13)
Note: Alarm Groups # 1 and # 2 are blank until configured.
