INTRODUCTION1.
ATTENTION!
This user manual extends the information from the installation manual to the configuration of the
device. Use the installation manual for more information.
ATTENTION!
In any case, SENECA s.r.l. or its suppliers will not be responsible for the loss of data/revenue or
consequential or incidental damages due to negligence or bad/improper management of the device,

the functions fully meet the customer's expectations or that the device, firmware and software should
have no errors or operate continuously.

CONNECTION OF THE DEVICES TO A NETWORK2.
CONNECTION OF THE DEVICE TO A NETWORK2.1.
The factory configuration of the IP address is:
Static address: 192.168.90.101
Therefore, multiple devices must not be inserted on the same network with the same static IP.
If you want to connect multiple devices on the same network, you need to change the IP address configuration
via the web server.
ATTENTION!
DO NOT CONNECT 2 OR MORE FACTORY-CONFIGURED DEVICES ON THE SAME NETWORK, OR THE
ETHERNET INTERFACE WILL NOT WORK
(192.168.90.101 IP ADDRESS CONFLICT)
If the addressing mode with DHCP is activated and an IP address is not received within 1 minute, the device
will set an IP address with a fixed error:
169.254.x.y
Where x.y are the last two values of the MAC ADDRESS.
This way it is possible to install more I/O of the R series and then configure the IP with the SENECA
DISCOVERY DEVICE software even on networks without a DHCP server.

OPERATING PRINCIPLE3.
The radio sensors send data via the Lora radio system. This technology allows you to travel long distances
and keep battery consumption at very low levels.
SENDING DATA FROM THE SENSORS TO THE R-GWR GATEWAY3.1.
The radio sensor can send data in two ways:
1) Timed
2) Timed + Event
In mode 1 the sensor sends data with a configurable time interval.
In mode 2 the sensor sends the data with a configurable time interval but, in the event of a digital input event,
it immediately sends the data.
Each R-GWR gateway can manage up to a maximum of 32 sensors.
COMMUNICATION WITH THE R-GWR GATEWAY3.2.
When the gateway receives a packet from an associated sensor it responds with an acknowledge packet.
If the acknowledge packet is not received, the sensor adds a random time (from 1 to 8 seconds) to the next
sending.
If sending an alarm packet (and if sending on "alarm" event is enabled) the sensor makes 5 attempts with a
random delay between them before returning to low consumption again.
When the R-GWR gateway sends the acknowledge packet, it also appends the current configuration (so if you
change the sensor configuration in the gateway this will be sent with the next communication).
When the ALARM parameter is active, an IN0 or IN1 input event immediately activates the sending of the
packet.
ATTENTION!
IT IS ALWAYS POSSIBLE TO FORCE SENDING CURRENT DATA FROM THE SENSOR TO THE
GATEWAY BY PRESSING THE IN3 PAIRING BUTTON.
ATTENTION!
IF THE R-GWR GATEWAY REMAINS OFF FOR A LONG TIME, IT IS NECESSARY TO TURN OFF THE
RADIO SENSORS IN ORDER TO NOT DISCHARGE THE BATTERIES

ATTENTION!
AFTER THE FIRST ACCESS CHANGE USER NAME AND PASSWORD IN ORDER TO PREVENT
ACCESS TO THE DEVICE TO UNAUTHORIZED PEOPLE.
ATTENTION!
IF THE PARAMETERS TO ACCESS THE WEB SERVER HAVE BEEN LOST, IT IS NECESSARY TO
RESET THE FACTORY-SET CONFIGURATION (SEE CHAPTER 6)
DEVICE CONFIGURATION4.2.
To configure the device, access the web server and select the section you are interested in.
After a modification to the configuration has been made, the changes must be confirmed with the "APPLY"
button and the device will restart autonomously.
The Reboot button reboots the device (not necessary in the event of a configuration change).
The Default button returns all the page parameters to the default settings.
