CU-08A TRACER unit
1. Unit description
The
CU-08A unit
is a device which uses a GPS receiver to detect the position
of a car, a motorcycle or cargo. The position can be ascertained any time via
a single SMS command or when the ignition is on, the unit can continuously
send it via a GSM network to a data-collection server where the data is further
processed into a vehicle log book. Simply said, the unit can be used both for
passive locating when it only answers a single command, and for the continuous
transmission of real-time data to a data-collection server. If the attempt to send
the data fails, the unit saves it in its internal memory and sends it later.
Journey commencement –
turning the ignition key on activates the GPS
module in the unit which starts assessing its position immediately.
The journey starting is signalled by a lit LED which is then lit permanently
for the whole duration of the journey.
Journey termination –
the journey is terminated automatically 20
seconds after turning the ignition key off. If the key is turned on again within
this period of time, the journey will not be split into two separate parts. This
feature eliminates splitting the journey in two, e.g. when the engine stalls
during acceleration from standstill and the driver restarts it immediately.
2. Unit installation and connection
2.1. Unit installation
The unit should be installed in the vehicle interior by a professional company.
It is suitable for vehicles with a 12V or 24 V power supply and a negative earth.
Disconnect the battery before installation. Nobody should be inside a vehicle
equipped with airbags while handling the battery. Some devices equipped with
a memory (clock, configurations, etc) could be erased when the battery
is disconnected. Avoid drilling into metal parts of the car body during installation.
The manufacturer shall not be held liable for any damage caused by incorrect
or unsuitable installation of the product.
When making connections, use a crimping tool fit for this purpose. If you
do not need some of the wire in the unit wiring, cut it 10 cm from the connector,
insulate it and fix it in a bundle with tape.
2.2. Status indication with an LED indicator
The unit indicates its status with an LED indicator.
Slow flashing
Logging into the system or the GPS signal
has been lost
Rapid flashing
The unit is waiting for configuration
SOS flashing (...---...)
Unit failure
Permanently lit
Motion indication, the journey is being
monitored
The LED is off
Journey termination or the unit’s power supply
has been disconnected
2.3. Wire connections
−
Black - ground
– connect to the original earthing point.
−
Red - +12V (24V) power supply
- connect to a cable leading from
the battery.
The
power supply should only be connected after
a thorough inspection of the whole installation!
−
Blue – ignition key activation
signalling.
Reacts to +12V (24V) from
the ignition box. Check whether the voltage in the connecting wire
is present even when the vehicle is being started.
−
Grey – panic
input, reacts
to connection to GND.
−
White - INP1 input –
logical input (for monitoring of external equipment),
reacts to connection or disconnection of GND. The status of this input
is transmitted to the data-collection server. Disconnection of GND =
the input is inactive, connection of GND = the input is active.
−
White and yellow - INP2 input
– journey type selection (private /
business).
Reacts to connection or disconnection of GND. The status
of this input is transmitted to the data-collection server. GND disconnection
= business, GND connection = private journey.
−
Orange – INP3 input –
logical input (for monitoring of external
equipment), reacts to connection or disconnection of GND. The status
of this input is transmitted to the data-collection server. Disconnection
of GND = the input is inactive, connection of GND = the input is active.
−
Yellow
–
AUX
output, switches a 12/24V positive power supply voltage
−
Green
– LED indicator
– install it in a visible place on the dashboard.
