Installation
Close the housing as watertight as possible f.i. by using silicone.
Surch for a suitable place somewhere in the trunk, to built in the base print (by preference as close as possible to
the sensor, see below)
Find a suitable place, approximately in the middle of the backside of the car, for installing the sensors f.i. : underneath
or above the bumper. The sensors can be mounted directly behind the bumper as well, but then you will have to
perforate the bumper with holes of a corresponding diameter (or wider) there where the sensors are situated.
REMARK : The sensors should be in a 90° angle position to the soil.
Before fixing the receiver, first of all you have to connect a piece of
cable with 6 conductors (or shielded 5 cable with 5 conductors, the
shielding having to be connected to the terminal GND) to its terminals
(to the terminals GND, +V, RW, DIS, S1 and S2), so that it can be
connected afterwards to the base print (use by preference a color
coding cable).
