Potentially Explosive Atmospheres

ME500-X
Trackunit ME500-X, Technical Manual v.1.1, January 2016 Page 8
The ME500-X unit cannot be turned off after installation, so any vehicle, moving
machinery, construction machinery installed with ME500-X etc. must not enter any area
with a potentially explosive atmosphere and obey all signs and instructions. Sparks in such
areas could cause an explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always marked clearly.
Potential areas may include: fueling areas (such as gasoline stations); below deck on
boats; fuel or chemical transfer or storage facilities; vehicles using liquefied petroleum gas
(such as propane or butane); areas where the air contains chemicals or particles (such as
grain, dust, or metal powders); and any other area where it would normally be advisable to
turn off motor vehicle engines it is not allowed to enter with a vehicle, moving machinery,
construction machinery installed with the ME500-X.
For Vehicles Equipped with an Airbag
An airbag inflates with great force. DO NOT place objects, including the ME500-X unit, in
the area over the airbag or in the airbag deployment area. If in vehicle wireless equipment
is improperly installed and the air bag inflates, serious injury could result.
Specific Human Absorption Rates (SAR)
THE ME500-X UNIT IS NOT DESIGNED TO BE WORN ON A PERSON’S BODY.
AS SUCH, BODY WORN TEST POSITIONS FOR THE ME500-X UNIT
ARE NOT REQUIRED BY EITHER THE IEC 62311 FOR GSM 900/1800 BANDS OR
FCC/IEEE/ICNIRP REQUIREMENTS FOR GSM 850/1900 BANDS.

Trackunit ME500-X, Technical Manual v.1.1, January 2016 Page 9
Delivered standard content
The delivered standard package content includes the following items:
1 x (GSM/UMTS)/GPS-unit of the model type ME500-X
1 x mounting cradle
1 x Li-ion Battery (May already be mounted inside the ME500-X unit)
1 x Fuse with fuse holder
In case the unit is delivered with SIM card from the factory (Either US or EU SIM card
as indicated on the product label), then the GSM number will be indicated on the
delivery note as well as on the package itself.
NOTE: In case the SIM card is delivered from factory it is mounted inside the ME500-
X unit.
Ready-to-Use, No Custom Programming Required
Simply connect the unit to supply voltage (12V/24V/48V DC). In its default configuration,
reports are sent nominally at 15-minute intervals or faster whenever there is motion.
Upon powering up, the device will self-initialize anywhere in the world and start
transmitting if an authorized GSM network is available. While a basic understanding of the
different ME500-X operational states is helpful, configuring the ME500-X unit does not
require a highly skilled software programmer or technician.
Cost-effective, Universally Available Communications
The ME500-X unit takes advantage of the near universal availability of GSM SMS text
messaging while also leveraging cost-effective GPRS data rate plans. Typical SMS plans
offer very extensive inter-network roaming capabilities, both within a host country and
internationally.
SMS plans also tend to be too pricey for applications requiring more than a few reports per
day. GPRS data plans, on the other hand, typically allow for lower recurring
communication costs although GPRS coverage and roaming can be restricted in some
areas.
The ME500-X unit takes advantage of both technologies by automatically selecting GPRS
wherever such service is available, while relying upon SMS text messages for
configuration purpose only. This helps minimize recurring communication costs while
allowing the greatest coverage possible.

ME500-X
Trackunit ME500-X, Technical Manual v.1.1, January 2016 Page 10
Installing the unit
Practical installation advice
•It is very important to be careful when installing the unit, as incorrect
installation will reduce the quality of the GPS position reports (Ex. could be a
jump in position or showing speed while parking) or in the worst case
scenario will prevent the unit performing any position reporting at all.
• The unit must be mounted either horizontally or vertically (sideways) using either
screws or strips. The unit must not be installed with the interface/supply cable
hanging down, as this definitely will reduce the GPS sensitivity.
Optimize the placement of the unit to increase the aerial view (through windows
etc.) as much as possible. For hiding the unit, make sure it is only mounted beneath
plastic parts or similar parts (wood), but not beneath metal parts.
• To reduce hum and noise in the FM radio it is recommended to place the unit at a
minimum distance of 20 inches (50 cm) from the radio or the loudspeakers.
Connections
The connections depend on the type of vehicles / machines etc. in which the GSM/GPS
unit is to be installed.
Different variants of the ME500-X device will have only a subset of the connections shown
in the table below. Please contact your nearest sales office, distributor or “Reseller” for
further information about the availability of other variants in your area.

ME500-X
Trackunit ME500-X, Technical Manual v.1.1, January 2016 Page 11
Power supply
The unit must be connected to either +12V, +24V, +36V or +48V battery voltage through a
1 amp. fuse. The use of a fused supply wire is important for not damaging the wires
related to the unit in case of a short circuit etc.
Digital inputs
The activation of a digital input requires a minimum high level voltage of 8V.
Digital output
The digital output has the type indication ”LO-side switch”, that connects the output to 0V
“ground”, when the output is active. This output can be used to control a relay powered
from an external DC supply voltage. The maximum current drawn from the output is
200mA and the voltage from the external supply voltage must not exceed 52V DC.
The output is protected against short circuits, overload and is also protected against over
voltage. For further information about connection possibilities of the digital output, see
chapters about installation later in this manual.
Motion/acceleration sensor
The unit has a built-in 3 axis acceleration sensor that is able to activate the unit if it, as a
consequence of disconnected supply voltage, is in stand-by mode.
1-Wire input
The 1-wire (Green wire) is designed to communicate with Dallas iButton Key or Trackunit
RFID/PIN reader for access control.
The 1-wire input is only operational when supply voltage (12V / 24V / 48V) is present.
It cannot operate on internal battery alone.
Installing the ME500-X as to surpass the main switch on the machine:
In case the main switch on the machine will break the negative wire (Ground wire), the
inputs may register a voltage level and start counting operating hours. To avoid this
situation the digital input 4 (Pink wire) should be connected to the chassis/ground on the
machine. Then send the following SMS to the unit (phone number) to activate the filtering:

Activate filter function on inputs. MT INFILT ON MTC ACK (SERIAL No.) INFILT ON
NOTE: Enabling the filtering function will disable the use of the digital input 4 as a
normal input.
NOTE: It is recommended always to connect digital input 2 to the ignition signal of the
vehicle or machine.
NOTE: For the “Send SMS” it is of no importance if small or capital letters are used in
the command string, or a mixture hereof.

Installation of the digital output
According to the E1 certificate of the ME500-X unit, it is prohibited under any
circumstances to use this output to control any equipment that may influence the safety of
the construction machinery and earth moving machines/vehicle operation and driving. The
output must only be used to control comfort equipment.
The example below shows a 12V relay function with a 12V DC supply voltage. It is also
possible to use a 24V relay with a 24V DC supply voltage etc. The current consumption of
the relay must not exceed 200 mA (DC current) and the relay contacts must be specified
to withstand the load that needs to be controlled.
NOTE: The output can only handle DC and not AC voltage. It is necessary to only use a
DC power supply for the relay.
Important! The power supply connected to the ME500-X GSM/GPS unit and
the supply voltage for the relay mounted on the digital output
must have a common ground connection.
One application example for the “Usable contact function controlled by the ME500-X”
signals shown in the figure above could be a “Start Relay”, blocking function, for
preventing unauthorized use of the moving machinery and construction machine or vehicle
outside normal working hours etc.
