4. MAINTENANCE
4.1 Precautions and protection
Do not scratch or press the cover of the device with sharp objects. You must not touch to the display
element with a sharp object. Do not fasten any accessories to the cover of the display or of the cen-
tral unit
To protect the electronics of the device, the covers must be always kept closed. The device contains
an internal heat management systems which controls the fan, so do not set any objects on or over
the central unit, which may prevent the ventilation of the device. If any failure occurs, please contact
the service.
4.2 Cleaning
- clean the filter of the CPU regularly
- keep the display and covers clean from dust, oil or other chemicals
- clean the device by using a weak detergent
- always use a soft towel for cleaning
Alkaline or other solvent, alcohol and other similar chemicals must not be used!
4.3 Software maintenance
The computer runs with Microsoft Windows or Linux operating system. Particularly Windows operat-
ing system is vulnerable for worms, viruses and attacks against known security holes. It’s essential to
keep your computer up-to-date with proper virus protection application, e.g. Norton Anti-Virus or simi-
lar, and use Windows update -feature regularly. Also using software firewall is very recommended,
considering that there are many of them available freely from e.g. internet and Windows XP has this
feature build-in.
5. INSTALLATION
General
The installation of the unit has to be performed systematically. Recommended installation order is:
- antennas (GPS, GPRS) and their cables
- cables of supplementary devices
- attaching cables to the vehicle
- testing the cables
- installation of the keyboard
- mounting of the central unit
- mounting of the display
- connecting the cables to the central unit
- communication test (GPS, GPRS etc.)
- peripheral test (printer etc.)
Note! The voltage of the vehicle must be disconnected during installation.
5.1 CPU mounting
- choose location, which is in accordance with the purpose
- ensure sufficient ventilation for the unit, do not use any closed
box or such
- mount the CPU in the vehicle
10

11
In the roof mounting flip the cover of the CPU.
5.2 Mounting antennas
The GPS and GPRS -antenna works on highest performance when installed outside of the cabin. It’s
recommended to leave 400 mm free space between similar antennas and GPS-antenna has at least
135° free signal space, both horizontally and vertically. If the vehicle has very oblique window, GPS-
antenna can be mounted inside of the cabin. Follow the installation manual which comes with the
antenna!
Note! Ensure that window is not coated with any material that could block signal.
5.2.1 Outdoor mounting
- see the instruction delivered with antenna
5.3 Display mounting
When mounting the display, the traffic safety has to be taken into consideration. Do not mount dis-
play so that will prevent visibility or disturb the control of the vehicle. Pay attention to passengers’
and driver’s safety to avoid unnecessary injuries in case of possible accident.
5.4 Keyboard and mouse installation
Choose the location for the keyboard and mouse, so that it will be easy to reach them. The USB con-
nector is recommended to be placed close to USB supplementary devices.
Always consider the traffic safety!
5.5 Cable installation
- make sure that the location of cables doesn’t cause any breaks or wear.
- install cables under the upholstery
- make sure that cables doesn’t rub against sharp objects
- don’t make sharp angles
- don’t twine cables

Wiring diagram; Digital I/O

5.6.1 Functions of the vehicle cable
Functions of the vehicle cable can be set according to user’s demand. Standard settings and wires
are described in connector layout on page 19.
- CON16/pin18 (Heat Start), if connected with wake-up signal (e.g. Webasto) to 12V/24V, the unit will
start preheating, otherwise when ignition key is turned on (selectable in Sunit Telematics).
The most of the features of the vehicle cable are adjustable in Sunit Telematics application, refer to
Appendix A - Sunit Telematics instructions.
6. INSTALLATION TESTS
6.1 Power cable test
Before connecting cables to the CPU they have to be tested. With this test one can ensure that de-
vices wouldn’t get damaged when current will be connected. Use the multimeter for testing
- grounding (GND): Test to the body of the vehicle with “beep” -function
- constant power supply (PWR-IN): measure the voltage 12V when the ignition key is off
- start of the pre-heating (Heat Start/DI5): Measure that voltage is 12V or 24V
- current of the ignition lock (Ignition): Measure that voltage is 12V or 24V when the ignition key is on
If these tests are passed successfully, cables are installed correctly.
6.2 Antenna tests
If the GPS or phone doesn’t get the connection after installation, the antennas shall to be measured.
Loosen the power connector (PWR) and check that the cables of antennas are properly in their own
connectors in the CPU. Check that the cables are undamaged.
GPS antenna
Measure that the resistance between the signal and ground is not in short circuit (not 0Ω) or cut
(not ∞Ώ).
Phone antenna
Measure that the resistance between the signal and ground is ∞Ώ i.e. infinitive.
6.3 Printer test
If the printer is connected, test it from operating system’s printer setup.
6.4 Phone test
The Sunit c On-board PC includes the internal GSM/GPRS-phone as option. The testing of the
phone is performed preferably with which is normally used in the assignments. If there isn’t such, test
can be performed with e.g. Windows HyperTerminal.
14

6.5 Data transfer and GPS test
The Data transfer test can be performed with Windows HyperTerminal.
Note! The GPS is connected to COM3 and the phone to COM4.
Write e.g. “GPS3”, click “OK”. Write phone number, select port (COM3 for GPS, COM4 for phone).
- bit rate = 4800 or 9600
- data bits = 8
- parity = none
- stop bits = 0
Click “OK”

7. USING THE COMPUTER
After the installation the cables must be checked before booting the computer!
7.1 Starting and shut-down
The starting mode is selectable in Sunit Telematics
Manual on-off (default)
- on: Press the on/off button briefly
- off: Use the operating system’s Shut-down feature only.
Automatic starting
- you can set the automatic starting adjustments in Sunit Telematics
Automatic shut-down
- you can adjust the mode of shut-down, delay and standby time in Sunit Telematics
Cold start
- the unit starts only after the pre-heating, when the temperature inside of the unit has reached +5°C.
Depending on the prevailing temperature, pre-heating can last 2 - 7 minutes. Blinking yellow led of
the display indicates that only CPU’s heating is on, when continuous yellow indicates both CPU and
display is heating.
With start of the unit, the following devices starts also:
- GPS is ready to receive data as soon as the operating system is running. GPS requires signal from
at least 3 satellites for location
- if the optional phone is installed, the search of the network is performed automatically.

17
7.2 Display adjustments
The display is equipped with automatic adjustment of the backlight, therefore manual adjustment of
the brightness is not recommended except in the dark
- adjust the minimum brightness by following instructions given in page 8
- manual adjusting effects only in twilight or in the dark
8. START-UP SIGNALS
The PC has internal control system which controls the status of the device. If the device states a
faulty function during start-up, it indicates it with audible signal; one long and one or more short
“beeps” according to the following list.
