First, the long cable into the greenhouse should be con-
nected to the Receiver. The correct RJ45 outlet must be
used when connecting the PoE injector to the GroSens
Receiver. The outlet is located inside the GroSens Receiver
housing (see below).
The cable between the PoE injector outside the green-
house and the Receiver inside the greenhouse cannot be
longer than 100 metres (see option 1). Standard Ethernet
cables: Cat5, Cat5e or Cat6 are sufficient.
If the distance between the PoE injector and the Receiver
is greater than 100 meters, an Extender must be installed
after every 100 metres of cable (see option 2). There is one
Extender provided in the set. The maximum distance from
the PoE Injector to the Receiver is 200 metres. Extra Exten-
ders to extend the maximum distance can be ordered from
GRODAN Customer Service if required.
When the GroSens Receiver is connected to the PoE
Injector, two LEDs should light up: the Power LED and Link
LED. The Power LED will light up immediately. The link LED will
turn on as soon as the GroSens Receiver has auto-discovered
the GroSens Smartbox; this can take several minutes. Wait un-
til the Link LED is lit before continuing the installation process.
After the connection is made, the housing can be closed.
It is best to locate the GroSens Receiver above the highest
point of the crop (at the end of the season). Position the Sen-
sors in the centre of the area and, for better wireless reception,
as far as possible from steel poles or other heavy greenhouse
structures. Fasten the Receiver with a tie-wrap or another sort
of easily removable mounting device in case the Receiver
needs to be relocated if the GroSens Sensors get out of range.
Please note: You must install the GroSens Smartbox first,
as indicated in the installation sequence. The GroSens
Receiver will only connect to a GroSens Smartbox that is
already running. The Receiver requires 24V of power. This
can also be realised by using a standard 24V adaptor. The
adapter should output DC voltage between 12-30 volts,
capable of supplying 500 milliamps of current.
