f) Lead the sensor cables into the cabin, but pay attention that they cannot touch any
rotating, moving or sharp parts, or hot surfaces (radiator, fan, engine block, etc.)! Do
not stretch the cables too much, but they cannot be too loose either. Fasten the cables
with cable ties or with electrical tape! Never knot or break the cables, because damaged
cables may lead to malfunction of the device and to the loss of warranty!
g) Connecting the sensors to the central unit:
GPS U1
Communication cable
In case of a 4-sensor system, only one central unit is needed. If a GPS U1 device is
connected to the system, the frontal sensors must be connected to ports 1. and 2., while
the rear sensors go to ports 3. and 4.
GPS U1
Communication cable
In case of a system with 6 or 8 sensors, two central units are needed. If you use them
with a GPS U1 device, then the two CPUs must be connected with the communication
cable of the set.
After it, choose which unit will be the primary CPU (does not matter which), and connect it
to the GPS U1 device. The frontal sensors must be connected to the primary CPU, while
the rear sensors go to the secondary CPU. This is important when the device states the
direction from which the signal comes
In case of two central units, it is recommended to use the power cable distributor that can
be bought separately. With this, only one of the power cables connect to the electrical
system of the car and the distributor powers the other unit.
If a GPS U1 device is connected to the system, it is forbidden to connect
the cigar lighter power cable, because it may disturb and damage the
electrical system of the vehicle!
