Introducing the
Repeater (Range Extender)
Since the signal range between a sensor and the PlantControl central unit is limited to a maximum of 200
meters, repeaters with a signal range of up to 3 kilometers have been developed. If several such
repeaters are used, the signal range can be extended up to 30 km. Power is supplied by either an AC
adapter or a solar cell.
Configuration options
Up to 30 repeaters can be connected with a PlantControl.
Up to 10 repeaters can be connected to each other in a row
(max. 30 km).
Up to 5 repeaters can be connected to one repeater.
Up to 60 sensors can be connected with a repeater.
Note:
The first repeater must be positioned within 200 meters from
the PlantControl.
No sensors may be assigned to the first repeater.
A PlantControl system requires a minimum of two repeaters.
Signal range is up to 3 km line-of-sight and dependent on the
type of terrain.
The repeater frequency band is 868 MHz. Therefore the
PlantControl as well as the sensors must be set to 868 MHz.
Control button / Connections
A. Power connection (power supply or solar cell)
B. LED
C. Control button
D. Interface for external antenna (optional)
Switching on/ switching off/ checking power supply
Please note that repeater are usually delivered with built-in
rechargeable batteries (8x AA).
1.
Unscrew the 4 screws and remove the front cover.
2.
Attach the battery connector to the battery holder (see picture).
By doing so the repeater is switched on.
3.
Mount the front cover.
4.
Plug now the AC adapter or solar cell to the power connection.
5.
To switch off the repeater the battery connector must be
removed from the battery holder. It is not enough to just pull out
the AC adapter or solar cell cable.
6.
Check by pressing the control button, whether the repeater is
receiving sufficient power. If the LED flashes, the repeater is
operational. If the LED does not flash then either there is
currently not enough power available (if a solar cell is used, the
repeater enters in a sleep mode if the battery voltage is < 8.2V in
and is only ready for operation again when the battery voltage
rises again) or the repeater is defective.
Operating (check also chapter "Initializing the repeater")
By pressing the control button, the repeater sends a test
message to the Plant Control. The test Telegram can be used to
identify the repeater (see also Plant Control menu Sensors>
Identify.)
To initialize a repeater, hold down the control button for 5
seconds (see also chapter "Initializing the repeater").
