3.Mounting and handling
This chapter contains recommendations for installation, handling and maintenance of the device.
3.1. Mounting
CCpilot VA has the capability to support two different mounting methods, either using an industry
standard RAM ball mount or mounting in a panel cutout. These two mounting methods are described
further below.
For both fastening methods, it is recommended to use 3 pc. M5 x 0.8 button head screws of type MRT
(Torx), length should be 12 mm. The recommended fastening torque is 1.5 - 2.0 Nm. Using a split ring
or toothed lock washer is recommended. Ensure that the M5 mounting screws are clean and dry before
mounting.
Note that the depth of the threaded holes is 9.5 mm. Be careful not to use too long screws which may
damage the device when tightened.
3.1.1. RAM mount
CCpilot VA is preferably mounted using a RAM mount, i.e. RAM-202U, a round base 1.5” ball mount
which allows adjustment of the display’s position and angle.

3.1.2. Panel mounting
Alternatively, the device can be mounted in a panel-cutout using a panel mounting bracket (article
number C000134-07), see figure below.
CCpilot VA with panel mounting bracket
The mounting bracket is designed for a panel thickness of 1.5 - 3.0 mm. Panel cutout dimensions are
according to figure below. A drawing in DXF-format for precision cutting of panels is available upon
request.
The device has a built-in gasket to provide some amount of sealing towards the panel. Ensure that the
device is mounted to a smooth, flat surface. Fastening the device to an uneven surface will affect the
sealing property and may stress the enclosure or damage the outer flange, leading to premature
failure. Additional gasket or other means for sealing may be required to reach higher IP levels.

3.2. Connecting to power supply
This chapter describes how the CCpilot VA is preferably connected to the power supply of a vehicle, or
other machinery. The principle is the same also for other types of installations.
Carefully read through the following sub-chapters before installing the device. Connector pinouts are
found in chapter 6.
3.2.1. Wire gauge
Wire gauge for the power supply should be dimensioned with respect to the total load current, the
cable length required and the worst case voltage drop allowed, considering the minimum operational
voltage of the device.
Current consumption of the CCpilot VA device is found in chapter 7.1.
Power consumption of external loads driven by the CCpilot VA device should also be taken
into account.
Note that the High side PWM outputs are automatically switched OFF when the supply
voltage drops below approximately 8 VDC, for example while cranking the engine of a vehicle
or machine. This is a measure for limiting the input current and voltage drop in the supply
cables.
As a guideline, the minimum wire gauge for the power supply should be: 0.75 mm2/AWG 18.
3.2.2. External fuse
To prevent cable fire in case of short circuit, an external fuse must always be used when powering the
device from a high current capable power source, for example a vehicle battery.
The fuse shall be located as close to the battery/power source as practically possible. A
recommendation is to place the fuse at a maximum distance of 15 cm (6 inches) from the (+)
terminal of the source.
Fuse rating shall be dimensioned with respect to wire gauge, maximum current consumption
and the inrush current of the device. Refer to chapter 7.1 for fuse rating details.
As a guideline, a slow acting fuse with 5-8 A current rating should be used.
Remember to also apply fusing for the on/off control wiring, see chapter 3.2.3 below.
3.2.3. External On/off signal
The device’s external on/off control signal should be connected to the positive supply line via the
vehicles or machines turnkey switch or a separate on/off switch (see switch “S2” in application
example, chapter 3.2.4).
Several CCpilot VA, or other devices, may be controlled by the same switch by joining their
on/off control signals. The CCpilot VA device has an internal pull-down of 20 kΩ (typ), giving
a worst case current of 2.0 mA per device at 32 VDC input.
The wire gauge for the on/off signal shall be dimensioned to handle the total switch current
and the fuse type and-rating shall be selected to prevent cable fire in case of cabling short
circuit.

As a guideline, a slow blows fuse in the range of 100-500 mA for the on/off signal should be
sufficient for most practically usable wire gauge.
3.2.4. Application example
Below is an application example schematic of the CCpilot VA power supply connection.
If the system has a main switch for completely disconnecting the battery ( S1 in schematic below), the
device’s power supply and on/off signal shall be connected after the main switch. Observe that this
switch is only intended for disconnecting all system loads to prevent draining of the battery during
prolonged dormant periods and shall not be used for starting/shutting down the CCpilot VA device on
a regular basis.
By connecting the power supply according to the example above, the CCpilot VA device(s) will
automatically start up when the Turnkey switch (S2) is closed and shut down when the switch is
opened.
Note that the on/off behaviour of the CCpilot VA described is the default configuration. Its response to
the on/off signal may be disabled or changed by user applications. For example, the signal may be
configured for suspending and resuming the device or the device may be configured to always start
when the power supply is available. See chapter 4 for more details and configurations available.

3.2.5. Precautions
Ensure that the device is shut down properly before switching off external power (main switch “S1”in
example above). Ensure that any application data is saved prior to turning off the device.
Sudden power disruptions may cause the device to shut down, potentially causing loss of user
data (if not written to flash) or, at worst case, corrupted flash storage areas. If the power
supply voltage sometimes fluctuates drastically, for example while running a starter engine,
the CCpilot VA device should be started after the vehicle engine has been started.
All cables to the CCpilot VA device shall be disconnected during welding to a machine.
Be advised that the CCpilot VA device consumes a small amount of power from the main
supply also when shut down or suspended (see chapter 7.1). Therefore, if the device has been
attached for a long period of time without the vehicle motor running, the battery may be
drained resulting in inability to start up the vehicle. A main switch for disconnecting the
device’s main supply is highly recommended in such situations (see application example,
chapter 3.2.4).
3.3. Grounding/touch-screen decoupling
This chapter applies primarily to touch-screen enabled product variants.
Capacitive touch-screens are, by design, sensitive to common-mode noise, i.e. electrical noise between
its ground reference and the ground reference of its surrounding and person operating the touch-
screen.
Therefore, the CCpilot VA device has a dedicated touch-screen grounding connection (connector J2,
pin 5) for decoupling common-mode noise from the main supply.
The dedicated touch-screen grounding is highly recommended to be used for reducing noise
susceptibility and avoiding false (unintentional) or imprecise touch detections. Connect a wire of
minimum length, less than 2 m (or 80 inches), from connector J2, pin 5 directly to the nearest ground
structure (vehicle chassis).
The touch-screen ground connection is capacitively connected within the CCpilot VA device
and will not cause ground-loops.
For best noise cancelation effect, the grounding structure used for touch-screen decoupling
should be proximate to both the CCpilot VA device and to the operator of the device.
3.4. Cable installation
Cables shall be installed in such a way that they don’t run any risk of being damaged, pinched or worn.
Avoid excessive bending and twisting of cables.
Use strain-relief on cables near the device to minimize stress on cables and connectors.
Properly snap the connectors to give reliable contact and sealing and to avoid unnecessary
strain.
Shielded cables are recommended and in some cases necessary to ensure reliable
communication and appliance with industrial EMC standards.

3.4.1. Recommendations for cable shields and coaxials
To achieve electromagnetic compliance and stable operation of the end system, shielded cables may be
required for CAN, Ethernet and USB interfaces. In addition, it is recommended to use 75 Ω coaxial
cables for connecting analog video sources to the device.
Note that the Ethernet and USB interfaces don’t have dedicated pins in the DTM connector for
connecting cable shields.
If shielded cable is used for Ethernet, the shield is preferably connected/grounded at the other
end of the cable (and remain unconnected close to the CCpilot VA device).
If shielded cable is used for the main USB port, the shield is preferably spliced and joined with
the USB ground wire externally. Avoid creating ground-loops in the USB cable by insulating
any attached USB-devices from ground structures connected with the CCpilot VA device.
Below are recommendations for inserting cable shields and coaxial cables into Deutsch DTM plugs to
achieve robust connections and retaining IP classification of the device.
1. Splice the cable shield (or coaxial inner and outer conductors) outside of the DTM plug and
use regular, round cables for insertion into the plug.
2. Minimize distance between cable joints and the DTM plugs for best shielding effect.
3.5. Special considerations
To ensure proper and reliable operation and to retain IP-classification of the device, below
recommendations must be followed:
The device should be placed in a way that prevents direct exposure to water or sunlight or near
hot-air vents.
To enable sufficient cooling, the device must be installed in a way that allows ambient air to
circulate around it. A clearance of at least 50 mm around the device is recommended.
To maintain IP classification, all three Deutsch DTM connectors must be attached to the
device. Blind plugs must be used for unconnected pins. The sealed USB-port hatch at the
backside of the device must also be properly attached.
The device has a GORE-TEX®membrane for ventilation, see location in chapter 2. For proper
ventilation of the device, dirt and water must be prevented from accumulating and covering
the membrane. Be cautious not to insert objects which may puncture or detach the membrane.
Doing so will violate the IP-classification and void the warranty of the device.
Install the device and any cables attached such that they are not subject to excess vibrations or
other potentially harmful stress.
Loose fasteners are a common cause for excessive vibration. Fasteners may come loose due to
improper mounting techniques such as omitting thread lockers (fluid locker or locking
washers) or by over/under-tightening. Proper tightening requires dry, clean fasteners and a
torque wrench.
If the device is exposed to chemicals, water, dirt or other pollutants, it’s recommended to have
it cleaned off as soon as possible. See chapter 3.6.1 for cleaning instructions.

3.6. Handling and maintenance
Handle the device with care and pay attention to the following handling instructions:
Disconnect all cables to the device during welding or when performing other service to the
machine imposing a risk of damaging electronic devices.
Service and repair to the device shall only be made by authorised personnel. If the device is
opened by unauthorised personnel, its warranty will be voided.
Scratches or other damages may occur to the display surface if it is exposed to sharp objects
or heavy impacts. This must be avoided to increase the longevity of the screen.
The internal NAND flash storage has a limited number of write cycles. Therefore it is
recommended that the amount of writing to flash is limited within software applications.
Always consider personal safety when installing and operating the device. For example, in
vehicle installations, maximatecc does not recommend that the device is being actively
operated by the driver when a risk of injury to people or damage to property is present.
3.6.1. Cleaning
To ensure proper and reliable functionality over time, pay attention to the following cleaning
instructions and precautions:
Wipe the device clean from dirt using a soft damp cloth, preferably of microfiber type. Larger
amount of dry dust may be swept off using a soft brush before wiping clean.
Avoid using alkaline, alcoholic or other potentially adverse chemicals for cleaning as doing so
may damage the device. However, small amount isopropyl alcohol may be used for removing
harsh stains.
Avoid spraying or by other means applying larger amount of water or alcohol directly to the
device. Instead, lightly dampen a cloth before using it for cleaning the device.
After cleaning, make sure that the device surface is left dry.
Never use high-pressure air, vacuum, water or steam to clean the device.
3.6.2. RTC clock back-up battery
Time and date information is stored in a memory sustained by an internal back-up battery.
The expected life time of the battery is approximately 10 years. Contact supplier for instructions on
replacing the battery.

4.Basic operation
This section covers basic operation of the device such as start-up, shut-down, suspend, resume, display
operation and status notification.
Observe that the behaviour of various on/off controls (external on/off control and front panel soft
keys) is user configurable in terms of:
Enabling/disabling functionality
Which push button that shall hold the on/off functionality.
Configurable timing parameters
Button backlight is used for status notification while starting up, shutting down or when de device is in
suspend mode. Both button backlight and the buzzer is software controllable for notifications from
user applications.
See chapter 4.5 for details of button backlight status notification.
The buzzer is also used for various error notifications, see chapter 4.6 for error code details.
4.1. Turning ON/OFF
The device can be configured to turn ON or OFF from one or more of the actions described in the
following chapters. Not all on/off triggers are enabled by default but all software configurable.
To ensure that data does not get lost or the flash memory becomes corrupt, it is recommended that
necessary data is saved and user application properly closed before the device is shut down.
Note that the shutdown triggers described herein don’t have affect if the device has entered Suspend
mode. The device must either first be resumed or reach its suspend time-out to be able to shut down.
See chapter 4.2 for suspend/resume details.
4.1.1. External ON/OFF signal
Turn ON the device by pulling the signal high (above 5.0 V), preferably by connecting to the positive
supply voltage through a turnkey switch according to the application example (see chapter 3.2.4).
This start-up action is enabled by default but may be disabled by user application.
Turn OFF the device by disconnecting or pulling the signal low (below 1.0 V) for at least 4 seconds
(default response time) , i.e. using the turnkey switch. See chapter 3.2.4 for application example.
The external on/off signal is configured as shut-down trigger by default but may be disabled
(or changed to suspend trigger) by software. The response time defaults to 4 seconds but is
user configurable.
Note that the device won’t restart automatically if the external on/off signal is brought high
while the device is in the progress of shutting down (shutdown may take several seconds). A
low-to-high transition must occur after the shutdown is fully completed to trigger a restart.
Increase the shutdown trigger response time in case you don’t want the CCpilot VA device to
shut down during short stops.

4.1.2. Front panel button(s)
Turn ON the device by short-pressing any of the front panel buttons configured as start-up triggers.
Note that none of the buttons are configured as start-up triggers by default.
Turn OFF the device by either short- or long-pressing any of the buttons configured as action triggers
with shutdown action assigned to either short- or long-presses.
Note that none of the buttons are configured as start-up triggers by default.
The time-out for detecting long presses is user configurable but defaults to 4 seconds.
4.1.3. “Always switched on” mode
It is possible to configure the device to always start up when external power is connected, i.e. without
using any particular on/off controls.
Note that this function is not enabled by default but may be enabled by the user.
The device can still use suspend/resume functionality. See chapter 4.2.
Shutting down the device is still possible. If shut down, the device can be started up by cycling
the main power or by any of the enabled start-up triggers, i.e. external on/off signal or
buttons.
4.1.4. Linux shutdown command
The device can be turned OFF by executing Linux shell shutdown commands, for example:
# s h u t d o w n
4.1.5. Forced shutdown
If the device stops responding, a forced shutdown can be performed by pressing and holding any
button configured as action trigger until the device is switched off.
The button press response time for the forced shutdown is double the user configurable long
press detect time –or a minimum of 8 seconds. Default press time for forced shutdown is 8
seconds.
Note that none of the buttons are configured as action trigger per default. This must be
changed by software to enable forced shutdown.
It is not recommended to use the forced shut down unless absolutely necessary - since doing so will
immediately switch off all internal voltages, regardless of ongoing operations. Any information which
was not saved to flash memory will be lost when performing a forced shutdown. Any ongoing writing
to the flash memory will be disrupted which may lead to a corrupted file system.
4.2. Suspending/resuming
Suspending and resuming are faster alternative to shutting down and starting up the device normally.
In suspend mode, the data remains in RAM to allow very fast wake-up without need for restarting the
operating system or software applications. Note that the device must be connected to external power
supply to maintain its state during suspend mode.

To prevent the device from draining a machines battery when suspended for a longer period of time, it
is possible to set a time-out after which the device is automatically shut down. The time-out is user
configurable and defaults to 60 minutes. It is also possible to disable this function (by setting the time-
out to zero).
Current consumption in suspend mode is somewhat higher than in shutdown but is still low enough to
allow relatively long suspend times without draining a machines battery. See chapter 7.1 for details
about current consumption at different modes and supply voltages.
Different ways of suspending and resuming the device are listed below:
Suspend triggers:
External on/off signal brought low (enabled as shut-down trigger by default)
Action trigger buttons (short- or long-press, not enabled by default)
Linux suspend command
Resume triggers:
External on/off signal brought high (enabled by default)
Action trigger buttons (not enabled by default)
CAN bus activity detection (not enabled by default)
Configurable Input state change (digital inputs)
Make sure to enable one or more start-up triggers prior to entering suspend mode, otherwise the
device won’t be able to resume.
4.3. Adjusting the screen (and button) brightness
With the CCpilot VA device it is possible to configure any of the front-panel buttons for adjusting
display brightness up or down.
Note that all button actions are disabled by default.
The screen brightness can also be controlled directly from user applications through APIs or
configured for automatic brightness adjustment through the ambient light sensor. When automated
dimming is enabled, the level of sensitivity can be adjusted.
Button backlight can be configured to automatically follow the display brightness setting. The button
backlight may otherwise be controlled directly from user applications through APIs.
4.4. Using the touch-screen
Note that not all CCpilot VA products variant contains a touch-screen.
Basic usage of the capacitive touch screen should be intuitive for most users. Refer to the CCpilot VA
Software guide for details about touch calibration.

4.6. Error codes (button backlight and buzzer notifications)
The internal buzzer and the button backlight is used for signalling error codes when the device shuts
down or cannot start up due to severe hardware or software failure.
When this happens, the device will either try restarting or remain shut off, and indicates the failure
reason by beeping the buzzer in different pattern. The pattern is a certain number of beeps and blinks
followed by a longer pause after which the sequence is repeated. The number of beeps and blinks is
important information if the unit is sent in for service/repair.
