1. Understanding the CM0504
e Controller Module (CM) 0504 is a general purpose input / output controller that includes a single
CAN interface, 5 inputs and 4 outputs with error checking. e main function of the module is to
provide a means of controlling high current loads through messages on the CAN bus. e outputs can be
congured as either high-side or low-side drivers. e module outputs can be congured to support up
to two full H-bridge motor drives to control directional motors.
e CM0504 is only available as a CAN slave module and does not support standalone operation.
However, it does support limited congurability, to specify things like input congurations, and update
rates for the messages presented on the CAN bus. e conguration tool is available from our website,
www.parker.com/ecd under ‘Support’.
Figure 1.1. CM0504 controller module
e CM0504 is designed to communicate through a J1939-based Controller Area Network (CAN) and can
be used in any CAN 2.0B application.
e CM0504 has many features, as follows:
• e CM0504 can monitor up to 5 inputs:
• 1 active-high with wake up input (can be used as power control).
• 4 programmable inputs (can be used as analog, digital, resistive, or frequency).
• e CM0504 has 4 outputs:
• up to 25 A load, module total 100 A (can be congured as high-side or
low-side).
• standard 500 Hz PWM default (capable of up to 2 kHz, engineering review required to verify for
each application).
• e CM0504 has 4 connectors (2x Deutsch DTHD 1 position, 1x Deutsch DTP 4 position, 1x Deutsch
DTM 12 position) that are used to interface with the inputs, outputs, power and CAN.
is manual describes the hardware components of the CM0504, but does not explain how to congure

4.1.2. Analog Inputs Connections
Sensor Power
Analog inputs are susceptible to system noise, which can aect the accuracy of the signal. Signal
accuracy can also be aected by ground level shift, which can cause inputs to activate when they
shouldn’t.
System noise
To prevent noise pickup on the sensors,
• Use the shortest possible wires when connecting analog inputs to sensors.
e following shows how to connect an analog input to reduce system noise:
Sensor
Analog Input
Internal to product
Sensor Ground
Figure 4.1. Analog input for system noise reduction
Ground level shift
To reduce ground level shift:
1. Dedicate one of the 2 system ground inputs (GND) to sensors that have dedicated ground wires, and
connect all sensor grounds to this system ground input.
2. Splice the other system ground inputs together in the vehicle harness (close to the connector) to
provide a better ground for the noisier low-side outputs and digital circuits.
3. Position the sensor’s ground connection near the system ground connections to ensure that the
signal remains within the digital activation range of the input.
Note 1: e system ground inputs are rated for low-current signals, which ensures the sensor’s ground is
very close in voltage potential to the system ground.
Note 2: Sensors that don’t have a dedicated ground wire are typically grounded to the vehicle chassis
through the sensor’s body.

4.2. Power control digital input
e CM0504 has 1 active-high power control digital input that is used for waking up (turning on) the
product (INPUT1).
is type of input has a pull-down resistor option only. When the input is active it turns on the power
supply pass transistor to power up the unit. e input is sensed directly by the microprocessor.

Note: e power control digital input voltage must be greater than 4.3 V before it is considered an active
high input.
e power control digital input wakes up the CM0504 when switched high to a voltage of 4.3 V or greater.
e CM0504 will shut o when an open circuit condition occurs on the power control digital input,
unless it is congured to ‘Wake on CAN’.
12
CM0504 User Guide
Page 20
4.2.2. Power control digital input connections
If the active high digital input is congured to wake up the module:
• e power control digital input is usually connected to the vehicle ignition, but it can be connected
to any power source in a system.
• To protect the harness that connects the CM0504 to the ignition, place a fuse of 200 mA or higher in
the circuit that feeds the CM0504.
• When battery power (VBATT) is connected, and the power control digital input is inactive, the
CM0504 will go into sleep mode.
• e CM0504 has ‘Wake on CAN’ capability. Even when it is not congured for wake on CAN, the bus
must be completely silent in order for the CM0504 to stay in low power sleep mode. Until the correct
wakeup conditions are sensed, the CM0504 will appear “o” (outputs o and no CAN tx) but there is
no way to keep its power supply o if there is CAN activity on the bus.
If your CM0504 must always be powered, the power control digital input does not need to be used. e
CM0504 can be congured to always be powered using the CM0504 Conguration Tool software.

exists.
5.1.2.2. Open load (high-side)
Open load faults occur when a high-side output pin is open circuit (not connected to a load). e
high-side output circuit uses a small amount of current on the output pin to determine if an open load
condition exists.
Note: High-side outputs must be o to detect an open load fault.

5.3.1.1. High-Side Output Connections
You must be aware of the following when connecting high-side outputs:
• High-side outputs are connected to the VBATT pins, which can be connected to a +12 V or +24 V
battery. e VBATT powers 4x 25 A outputs. Maximum load on the VBATT is 100 A.
• High-side outputs can provide switched battery power to a variety of load types in a vehicle.
If large inductive loads are used, and the high-side output is providing a continuous PWM signal, then
the PWM peak current must not be greater than the specied continuous current for the output (in
continuous mode, the average current ow through the diode at 50% duty cycle is approximately equal to
½ the peak current).

When connecting high-side outputs, ensure you follow these best practices:
• High-side outputs should not be connected to loads that will draw currents greater than the
maximum peak current, or maximum continuous current.
• e grounds for the loads should be connected physically close to the CM0504 power grounds.

5.3.1.3. H-Bridge Connection
e high-side/low-side outputs can be congured to be an H-Bridge (controlled by activating the one you
want to be high side). An H-Bridge allows loads to be controlled by both high side and low side switches
at the same time.
H-Bridge connection allows loads to have current reversed through them which allows several load types
to reverse direction (motors, solenoids, etc).
ere are 2 H-Bridge options that the CM0504 can accommodate. ese are congurable in the Software
Tool. Congurations are:
• 2 separate H-Bridges that function independent of one another and can handle up to 25 amps each.
Please reference the Software Tool for how you must pin the CM0504
• 1 H-Bridge that gangs output pins together. In this conguration that CM0504 can sustain up to 50
amps across this H-Bridge. Please reference the Software Tool for how you must pin the CM0504
Size your fuses and wires accordingly when altering the output conguration.
Improper fusing and wiring can result in a re.

6. Power
e CM0504 is powered by the vehicle battery. e CM0504 operates in a 12 V or 24 V system, and can
operate from 9 V up to 32 V, with over-voltage protection at 36 V.
When the CM0504 is congured to go into sleep mode, the controller is turned on by applying power to
the power control (wake-up) input or a CAN message.
6.1. Logic and output power
e CM0504 has 2 pins, labeled VBATT, dedicated to providing power for logic and outputs, and 2 pins,
labeled GND, dedicated to grounding the CM0504.
Note: e power and ground connections are usually paralleled over several pins to minimize voltage
drops on higher current applications.
6.1.1. Logic and output power capabilities
e VBATT pins that provide logic and output power are internally connected inside the CM0504.
Logic power refers to the logic circuit, which consists of the microprocessor, RAM, etc. e logic circuit
can draw a maximum of 250 mA.
Output power refers to the output circuits connected to the battery positive and ground terminals. Each
output circuit can draw a maximum of 25 A.
e following table provides specications for the CM0504 logic and output power:
Logic and Output Power Specifications
Item Min Nom Max Unit
Input voltage range 9 32 V
Over voltage 36 V
Current draw in on state (excluding outputs) 250 mA
Current draw in sleep mode (see note 1) 0.6 1.7 mA
Inline fuse required on power circuit pin 130 A
Number of VBATT pins 2 -
Number of ground pins 2 -
Note 1: Current draw in sleep mode depends on the output conguration. Sleep mode current draw will
be lesser value when the outputs are congured as HS output.
6.1.2. Logic and output power connections
When connecting the CM0504 logic and output power, note that:
• Logic and output power connections are made using the VBATT and GND pins.
• When there are multiple output power pins, the number of wires needed to connect the CM0504
power depends on the amount of current required by the application.
• It is recommended that you use the largest AWG wire allowed by your connector for the VBATT
and GND pins, to meet the amount of expected output current; however, this is not always true
and depends on your application.

• e CM0504 is protected against reverse-battery connections by an internal high-current conduction
path that goes from ground to power.
• Select fuse sizes by multiplying the maximum continuous current during normal operation by
1.333 (75% de-rating factor). Do not use slow blow fuses for this application.
• All power connections to the CM0504 should be fused to protect the vehicle harness.

7. Communication
e only type of communication available to the CM0504 is Controller Area Network (CAN)
communication.
7.1. Controller area network
e CM0504 has 1 Controller Area Network (CAN) communication port(s) available. e CM0504
hardware provides controller area network (CAN) communication according to the SAE J1939
specication, making the CM0504 compatible with any CAN-based protocol through software.
CAN communication is used to communicate the status of multiple modules that are connected together
in the same network.
7.1.1. J1939 CAN Capabilities
e CAN communicates information at a rate of 250 kbps. CM0504 input and output information is
transmitted through the CAN at a broadcast rate of 40 Hz. Lack of regular CAN communication is an
indication that there is either a problem with a module in the network, or a problem with the CAN bus.
e following table provides specications for the CAN:
Item Min Nom Max Unit
Onboard terminator option - No -
Wake on CAN option - Yes -
Baud rate - 250 - kbps
J1939 compliant - Yes -
7.1.2. J1939 CAN Installation Connections
e CAN connection for the CM0504 should conform to the J1939 standard. e J1939 standard is a
robust automotive specication that is a good CAN installation guideline even when the J1939 CAN
protocol is not being used.
For a list of J1939 connection considerations, refer to the SAE J1939 specications available through the
Society for Automotive Engineers. SAE J1939-11 covers the physical aspects of the CAN bus including
cable type, connector type, and cable lengths.
Note: e standard variant of the CM0504 does not have a CAN termination resistor, which is based on
the assumption that the CAN bus is terminated in the harness.
e following lists the elements that are required for a J1939 CAN connection:
• CAN Cable: A shielded twisted-pair cable should be used when connecting multiple modules to
the CAN bus. e cable for the J1939 CAN bus has three wires: CAN High, CAN Low, and CAN
Shield (which connect to the corresponding CAN_HIGH, CAN_LOW, and CAN_SHIELD pins on the
connector). When a module does not have a CAN_SHIELD pin, the CAN Shield should be connected
to an available ground terminal attached to the negative battery. e CAN cable must have an
impedance of 120 .
26
CM0504 User Guide
Page 34
• e CAN cable is very susceptible to system noise; therefore, CAN shield must be connected as
CAN Network Backbone
follows:
a. Connect CAN Shield to the point of least electrical noise on the CAN bus.
b. Connect CAN Shield as close to the center of the CAN bus as possible.
c. Use the lowest impedance connection possible.
Note: Ground loops can damage electronic modules. e CAN Shield can only be grounded to one point
on the network. If grounded to multiple points, a ground loop may occur.
• CAN Connectors: Industry-approved CAN connectors are manufactured by ITT Cannon and
Deutsch, and come in either T or Y congurations.
• CAN Harness: e CAN harness is the main backbone cable that is used to connect the CAN network.
is cable cannot be longer than 40 meters and must have a 120 terminating resistor at each end.
e 120 terminating resistors eliminate bus reections and ensure proper idle-state voltage levels.
• CAN Stubs: e CAN stubs cannot be longer than 1 meter, and each stub should vary in length to
eliminate bus reections and ensure proper idle state voltage levels.
• Max Number of Modules in a System: e CAN bus can handle a maximum of 30 modules in a
system at one time.

marine application, ensure it is protected from excessive salt spray.
Before mounting the CM0504, ensure you review the following environmental and mechanical
requirements.
Do not install the CM0504 close to any signicant heat sources, such as a turbo, exhaust
manifold, etc. Also avoid installing the CM0504 near any drive-train component, such
as a transmission or engine block.
e CM0504 should be mounted with the connectors facing down, so that moisture drains away from it,
as shown in the following:
Figure 8.2. CM0504 mounting orientation
8.4. Mounting the CM0504 to a Vehicle
It is up to the original equipment manufacturer (OEM) to ensure the product is securely mounted to the
vehicle.
e following guidelines are related to physically attaching the CM0504 to a vehicle:
• Secure the CM0504 with bolts in all bolt holes using Hex Head 1/4”-20 or equivalent metric size (6
mm) bolts.

8.5. Designing and Connecting the Vehicle Harness
e vehicle manufacturer is responsible for designing a vehicle harness that mates with the CM0504
connector(s).
e vehicle harness design depends on the following:
• How the CM0504’s inputs, outputs, communication, and power pins are congured.
• Other components on the vehicle and their physical locations.
• e routing of the harness.
Details on recommended wire diameters for use with the product connector are covered in the
connector manufacturer’s datasheet. Wire diameters used should be sucient for the expect module
current.
Once the vehicle harness is designed, it can be connected to the CM0504 simply by clicking the mating
connectors into the connector ports on the CM0504.

10. Application Examples
e purpose of this section is to provide examples of how the CM0504 can be used for dierent purposes.
e following examples (used for illustrative purposes only) are covered in this section:
• Implementing safety interlocks
• Controlling indicator lights
• Controlling a proportional valve
• Controlling motor speed
• Using one analog input as two digital inputs
• Connecting sensors
10.1. Implementing Safety Interlocks
Safety is paramount when creating controls for a vehicle.
One safety feature that can be implemented with the CM0504 is to ensure the vehicle doesn’t move when
it is not being used, and no one is sitting in the operator’s seat.
To prevent the vehicle from moving when no one is sitting in the operator seat:
1. Place a seat switch interlock on the operator seat and connect the switch to a
digital input.
2. Write application code for the digital input so that it shuts down critical vehicle
functions when the switch is open (when no one is sitting in the seat).
Note: e example above may cause unwanted shutdowns if the operator moves around while
controlling the vehicle. To prevent this, use software ltering that will prevent the vehicle from shutting
down unless the switch is open for more than a dened period of time.

10.3. Controlling a Proportional Valve
e CM0504 can be used to control a proportional hydraulic valve through a high-side output with PWM
capability, and a low-side output with current sense.
Note: e CM0504 has Proportional-Integral-Dierential (PID) capabilities that make it possible to
control devices like proportional valves through software. Refer to the appropriate software manual, or
contact your Parker Vansco Account Representative for more details about software. is section only
provides hardware connection information.
When making the connection, it is highly recommended to use the high-side and low-side outputs in
pairs to avoid potential problems.

• e high-side output would drive power to the valve coil and adjust the duty cycle of a PWM signal.
• e low-side output would be used as a return path to ground for the valve coil, and provides
feedback on the amount of current owing through the valve coil.
e application code should be written so that the PWM duty cycle for the output is adjusted to achieve a
target current through the valve coil.
• If current feedback is lower than target, the PWM duty cycle should increase to boost average current
through the valve coil.
• If the current feedback is higher than target, the PWM duty cycle should decrease to reduce average
current through the valve coil.

10.4. Controlling Motor Speed
e CM0504 can be used to control the DC motor speed of motors that provide a tachometer output.
Note: e CM0504 has Proportional Integral Dierential (PID) capabilities that make it possible to
control devices like proportional valves through software. Refer to the appropriate software manual, or
contact your Parker Vansco Account Representative for more details about software. is section only
provides hardware connection information.
To do this, you would use a high-side output with PWM capabilities to control the speed of the motor,
and a DC-coupled frequency input to monitor the output from the motor.
e application code should be written so that the PWM duty cycle for the high-side output is adjusted to
achieve a target speed (frequency) for the motor.
• If the frequency feedback is lower than target, the PWM duty cycle should increase to boost the
average current through the motor to speed it up.
• If the frequency feedback is higher than target, the PWM duty cycle should decrease to reduce
average current through the motor to slow it down.

10.5. Connecting Various Sensors
Motor
ere are many types of sensors that can be connected to the CM0504, as follows:
• Open collector sensors
• Variable resistance sensors
• Variable reluctance sensors
• Switch sensors
• Voltage sensors
• CMOS sensors
• Potentiometer (ratiometric) sensors
Note 1: To optimize the reading accuracy for sensors, dedicate one of the main ground pins (called GND)
as a low-current ground return for all sensors on the vehicle.
Note 2: When connecting sensors to the CM0504, use the sensor’s specication to ensure that the
CM0504 is congured correctly for the sensor.
10.5.1. Open Collector
Open collector sensors are compatible with each type of input on the CM0504.
Open collector sensors are typically used in applications that require digital or frequency measurements.
ey work by pulling voltage down to ground or up to power when activated, and are basically a switch
that turns on and o.
Note: Open collector sensors need a pull-up or pull-down resistor to bias the state of the sensor when the
sensor is not activated. Pull-up and pull-down resistors are internal to the CM0504.

10.5.2. Variable Resistance
Variable resistance sensors change impedance to represent it’s measured value, and are compatible with
analog inputs.
Variable resistance sensors are typically used in thermal and pressure applications. ey work by
changing the voltage reading on the sensor according to changes in pressure or temperature in the
application.
e CM0504 cannot measure resistance directly.

To make the CM0504 measure resistance accurately, do the following:
• Include a precision pull-up resistor between the sensor and the sensor power output (called
SENSOR_SUPPLY).
• Ensure the value of the precision resistor allows the maximum possible resolution for the sensor’s
input.
• Dimension the precision resistor to get the maximum voltage range from the sensor.
Note: Variable resistance sensor accuracy may suer at the extremes of the sensor’s range. A tolerance
analysis should be performed to ensure measurement accuracy is acceptable for your application.

10.5.3. Variable Reluctance
Variable reluctance sensors are typically used in frequency measurement applications, and are
compatible with AC-coupled frequency inputs.
Variable reluctance sensors do not require power (the power is induced), and they create frequency by
out-putting a sine wave type signal. ey work by using an increase or decrease in a magnetic eld to
detect the proximity of a part or device.

A switch is a type of sensor that uses mechanical contacts in one of two states: open or closed. Sensor
switches are used to turn sensors on and o, and can be wired directly to digital inputs.
Active-low sensor switches are common. To use active-low switches, the internal pull-up resistor on the
input that the sensor is wired to must be enabled.
Use of active-low switches is not recommended. A broken wire on this type of switch, if it
makes contact with the chassis, will activate the function.
Active-high sensor switches are another common type which are generally safer. To use active-high
switches, the internal pull-down resistor for the input that the sensor is wired to must be enabled.

10.5.5. Voltage
Voltage type sensors work by driving an analog voltage signal to report the sensor’s measured value.
Voltage sensors are compatible with analog inputs, and are typically used in applications that require
variable voltage measurements.
Note: Ensure you congure the analog input voltage (gain and attenuation factors) so the input’s voltage
is close to, but higher than, the maximum output voltage of the sensor.

A sensor with a CMOS-type output drives a high and low signal, and is typically used in digital and
frequency applications, and therefore, CMOS sensors can be wired directly to digital and frequency
inputs.

CMOS
Potentiometers and other ratiometric type sensors can be wired directly to analog inputs.
Potentiometers are resistive devices that use a wiper arm to create a voltage divider. Changes to resistive
measurements happen as the wiper arm moves along a resistive element.
When connecting potentiometer sensors, it is important to do the following:
• Connect one end of the sensor to the SENSOR_SUPPLY pin, and the other end to a GND pin on the
CM0504.
• Connect the sensor signal to an analog input.

10.6. Using one Analog Input as Two Digital Inputs
e CM0504 allows you to use one analog input as two digital inputs, which is useful in reducing harness
lead or if you are running out of digital inputs in your system.
To do this, you would connect the analog input to a single pole, double throw (SPDT) switch.
Note: You will need to write your application logic to act according to the voltage value readings
provided by the analog input. Refer to the appropriate help le, or contact your Parker Vansco Account
Representative for more information.
When making the connection, ensure there is a voltage dierence between the two pins on the SPDT
switch. is can be done by
• enabling the internal pull-up resistor on the analog input (done through software)
• adding a resistor to one of the pins on the SPDT switch.

11. Software
e CM0504 software is responsible for providing general mechanisms to control the outputs (including
detecting fault conditions), monitor the inputs, and transmit/receive J1939/CAN messages. e software
on another level uses these mechanisms to implement some sort of application program. e default
application for this product is to perform as a slave controller, which receives CAN messages from a
master controller telling it how to drive the outputs, and transmits CAN messages reporting the state of
inputs and fault status of outputs.
is document is not intended to explain the CM0504 internal code in detail, but rather to document
how to congure and use the CM0504 with its PC conguration tool.
11.1. CM0504 diagnostic tool
ere are a few general things to point out about the tool:
• the GUI is basic — the main menu pops up when you right-click on the tool window
• the tool follows the convention that blue labels/widgets (in this document and in the GUI) denote
congurable properties — “undened” is a valid conguration value for some congurable
properties. Undened values are shown as blank/empty boxes. You can right-click on associated
widgets to pop up a menu allowing you to change a property’s value to undened. By denition,
operational values cannot be undened.
• green labels/widgets (in this document) denote one-time congurable properties that generally
were congured at the factory
• gray labels/widgets denote properties that cannot be changed by the user
• GUI appearance/behaviour may change depending on user selections, and in some cases depending
on the values of some properties. For example, some widgets are hidden or disabled when
operational values are not selected. For channels that are ganged (or part of an H-bridge), only
widgets associated with the gang “leader” (or master “leg” of the H-bridge) are enabled.
• the diagnostic protocol used between the tool and the CM0504 is robust, however, it is possible to
confuse the tool so that it won’t talk to the CM0504. is is especially true if you recongure the
CM0504’s J1939 identity, or if you unplug one CM0504 and plug in another
• there may be multiple modules on the CAN bus, some which are not CM0504’s — generally, the tool
interacts with only one CM0504 at a time (typically the rst one it happens to see, but the user can
choose another)
• for various reasons, a CM0504 may be plugged in to the bus but holding itself silent, so the tool
is unaware of its presence. Similarly, the module may be talking on the bus but the tool does not
recognize it as a CM0504 (because it has been incorrectly congured). e user may need to take
some action to “wakeup” or “unlock” the CM0504, or force the tool to recognize it as a CM0504.
• the tool attempts to be backwards compatible with older versions of CM0504, but there may be
scenarios where an older CM0504 didn’t support a feature, which is not handled well by the tool
• the CM0504 supports selectable CAN bit rates (100K, 250K, 500K & 1M), but PC tool currently only
supports 250K

Note: As of the date of this publication, hardware input numbers and software input numbers
are dierent. Keep this in mind as you use the software tool.
Hardware INPUT1 = software INPUT5, hardware INPUT2-INPUT5 = software INPUT1INPUT4.
11.1.1. Using the tool
In user mode, the tool is a single/main window containing the following elements:
• a drop-down list box (in the upper left corner of the window) showing the SA (Source Address) of the
currently connected CM0504 — if you drop down the list, you can see what other CM0504’s are (or
were) on the bus, and select another one to talk with.
Figure 11.1. Source address claim

• radio buttons to select between Operational Values and Cong Settings, i.e. regarding what kind of
values are displayed on the main window, or which are shown in the input/output properties dialog
boxes. When the cong settings option is selected, properties that are not congurable are shown as
blank values.
Figure 11.2. Op values and cong settings
• the Install S/W button — the user will be prompted to select a .pkg le that contains the S/W he
wishes to install. If there are multiple CM0504’s on the bus, the user can select which ones to get
the install. (Currently, the tool installs all components from the pkg — the planned behaviour was
to not reinstall the same version of a component, and to ask the user whether an older version of a
component should be installed over the existing newer version.). A dialog box pops up showing the
progress as each component is installed.

Note that columns labeled IN1 to IN4 correspond to the CM0504’s four general purpose inputs, IN5
corresponds to what is considered its 5th input which is also a H/W wakeup signal, IN6 corresponds
to the input used with a keyed resistor as the module’s harness address, and the last 2 columns
correspond to external and internal power supply voltages. Only the four general purpose inputs are
congurable, with input type RIN supported in H/W for channels IN3 & IN4 only.
• depending on input type, Value shows properties DIN, AIN, FINfreq, FINduty, FINcount, or RIN
• what Raw Value shows depends on input type — for AIN, it shows AINinternal; for RIN it shows
AINraw; for all else it shows nothing, except for IN5 (xed as DIN) it shows FINcount
• Raw Ref shows the RINref property

• Simulate Master… — puts the PC tool into a special mode where is plays the role of a very primitive
“master” controller to a CM0504 that is running the slave controller application. While in this
mode, the PC tool displays a dialog box that shows the PWM frequency and duty cycle the master is
requesting for each channel (the user can change these) and the input state and output fault status
being reported by the slave. It also shows the CAN messages being sent and received.

• Restart CM0504 in passive mode — this causes the PC tool to send a special diagnostic protocol
command telling the CM0504 user application to go into passive mode. In passive mode, the user
application essentially stops running, other than allowing you to get/set its UDP’s. You might want
to do this if you are trying to use the PC tool to manually control I/O’s, and the user application is
ghting you, or if the user application is hammering the bus with a high CAN message rate (i.e. due
to an incorrect conguration), and you are having trouble trying to recongure it.

• Temporarily unlock comatose CM0504 — there are various situations where the CM0504 deliberately
holds itself o the CAN bus. One of the ways this can occur is if the CM0504 is a “asleep” waiting
to Rx a certain PGN to “wake up”, and you don’t know what the value of its keepAlivePGN property
is. is menu item causes the PC tool to send a special CAN message that tells the CM0504 to stop
holding o and announce itself.
