3�- INSTALLING THE DEVICE
3.1.- PRELIMINARY RECOMMENDATIONS
In order to use the device safely, it is critical that individuals who handle it follow
the safety measures set out in the standards of the country where it is being used,
use the personal protective equipment necessary (rubber gloves, face protection
andapprovedame-resistantclothing)topreventinjuriesduetoelectricshockor
electric arc due to exposure to current-carrying conductors and pay attention to
the various warnings indicated in this instruction manual.
The LR1RS+mustbeinstalledbyauthorisedandqualiedstaff.
The power supply must be disconnected before handling, altering the connections or replacing
the device. Handling the device while it is connected is hazardous to people nearby.
It is essential to keep the cables in a perfect condition to avoid accidents, personal injury and
damage to installations.
Limittheoperationofthedevicetomeasuringthespeciedcurrentorvoltagevalues.
The manufacturer of the device shall not be held responsible for any damage resulting from the
user or installation company failing to observe the warnings and/or recommendations indicated
in this manual nor for any damage resulting from the use of non-original products or accesso-
ries or those from other brands.
Do not use the device to take measurements if you detect an anomaly or malfunction.
The device must be disconnected from its power supply sources (power supply
and measurement) before undertaking any installation, repair or handling opera-
tions on the device’s connections. Contact the after-sales service if you suspect
that there is an operational fault in the device.

4.3.- OPERATING PRINCIPLE
The LR1RS+ is a gateway for converting data between the RS-485 physical environment and
the LoRaTM long-range wireless network.
These devices can be used to connect multiple RS-485 buses to a master, considerably reduc-
ing the cabling required. This can be done by simply connecting an LR1RS+conguredasthe
Master to the RS-485 master, and an LR1RS +conguredastheSlavetoeachofthebusesto
be connected; see Figure 4.

Figure 4: Example of LoRaTM connection�
There can be up to 32 end devices on each communications bus.
Communication between the LR1RS+ master and slave devices is fully transparent, therefore
allowing straightforward installation by simply controlling transmission time between messages
and the time-out period from the application’s master.
4.4.- LoRaTM COMMUNICATION
The device is connected to LoRaTM radio technology for private networks.
LR1RS+ devices can only be used in private networks and cannot be connect-
ed to LoRaWAN networks.
In Europe the frequency for LoRaTM communications is the 868 MHz ISM free band, allowing
congurationofupto9differentchannelsbetween865.1MHz(channel0)and869.85MHz
(channel 9). The default frequency is 869.525 (channel 7).
The device has 10 transmission and reception modes (Table 6) in order to select speeds be-
tween 300 bps and 21875 bps, with the option of increasing communication speed by trading
off transmission signal range.

11
Instruction Manual
LR1RS+
A period of silence during which the device cannot transmit has been set in order to respect the
spectral limitation, in accordance with the transmission mode selected in the master; during this
time, the RF LED lights up in blue and the device returns “Occupied” through the serial channel.

4.5.- RS-485 COMMUNICATION
The LR1RS+ have one RS-485 communications port, with MODBUS RTU ®, for reading and
writing the device parameters.
In the Modbus protocol uses the RTU (Remote Terminal Unit) mode.
The Modbus functions implemented in the device are as follows:
Function 0x03: Read holding registers.
Function 0x06: Preset single register.
Function 0x10: Preset multiple registers.
Note: All the adresses of Modbus memory are in Hexadecimal.
