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

4.2.2.1. PAIRING A NEW SENSOR
To pair one or more new sensors it is necessary to follow the procedure below:
1) Power up the R-GWR gateway and the radio sensor
2) In the gateway press the "START NEW SENSOR PAIRING" button in the "Status" section of the web
server. The STS LED of the gateway will start flashing.
3) In the sensor you want to pair, press and hold the pairing button until the red LED lights up
(transmission).
4) If the green LED of the radio sensor (radio reception) lights up, the association was successful and the
new sensor with its data will appear in the "Status" section of the R-GWR gateway web server.
5) Press the pairing buttons of each sensor you want to pair as in the previous point
6) Once all the sensors have been paired, press the "STOP NEW SENSOR PAIRING" button in the R-
GWR web server “status” section.
7) The STS LED of the R-GWR gateway stops flashing.

Page 14
Represents the status of the sensor, if the sensor has not sent the data within the FAIL TIMEOUT time, the
STATUS field goes into fail.
ATTENTION!
IT IS POSSIBLE THAT IN SOME SITUATIONS YOU CANNOT DETECT THE CORRECT STATUS OF THE
BATTERY, AND THEREFORE IT WILL BE DISCHARGED EVEN IF THE STATUS IS OK.
4.2.2.3. CONFIGURING A SENSOR
At each communication, the gateway sends the current configuration to each radio sensor.
ATTENTION!
IF YOU CHANGE THE CONFIGURATION OF A SENSOR IN THE R-GWR WEB SERVER, THIS WILL BE
SENT TO THE SENSOR IN THE NEXT COMMUNICATION
To configure a sensor, press the relative "SETUP" button in the "Status" section of the R-GWR web server:
SEND TIME [ x 30s] (default: 15 minutes)
Represents the time to send data to the gateway in quanta of 30 seconds
INPUT 0 (IN0)
Configures the type of operation of input0 (terminal input):
ALARM-FALLING EDGE = Digital input active in the transition from 1-> 0 of the input signal
ALARM-EDGE = Digital input active in the passage from 1-> 0 and from 0-> 1 of the input signal
COUNTER = The counter on digital input IN0 is activated, the count takes place in the transition from 1-
> 0
WATER SENSOR = The flood detection mode is activated, it also requires the Water Sensor
configuration on INPUT1.
ANALOG INPUT = The 0-30V voltage measurement mode is activated from the IN0 input
INPUT 1 (IN1)
Configures the type of operation of input1 (digital input / magnetic reed relay):
ALARM-REED-RISING EDGE = Digital input active in the transition from 0-> 1 of the input signal
ALARM-REED-FALLING EDGE = Digital input active in the transition from 1-> 0 of the input signal
WATER SENSOR = The flood detection mode is activated

ALARM
Selects whether to activate the radio packet immediate sending mode for inputs IN0 and IN1. It is considered
only for the following operating modes:
INPUT0 = ALARM-RISING EDGE, ALARM-FALLING EDGE or WATER SENSOR
INPUT1 = ALARM-REED-RISING EDGE, ALARM-REED-FALLING EDGE or WATER SENSOR
LINK TX
Sets the transmission power of the radio sensor, selectable between:
0 dB (minimum power, maximum battery life) to 14 dB (maximum power, minimum battery life)
AUTO allows you to automatically calculate the optimal transmission power.
In AUTO mode the sensor performs the following procedure:
1) The sensor sets the minimum power (0 dB) and, at each sending, raises this power
2) When the sensor gets 2 consecutive responses from the gateway it uses this transmission power.
It is therefore possible that there are transmission errors in the initial phase if this mode of operation is used.
The procedure can take from 2 to 5 transmissions to be completed and therefore, based on the sending time
set, it can last several minutes/hours.
To speed up the procedure, it is possible to force communication in the radio sensor by pressing the pairing
button IN3 for at least 5 communications.
To carry out a new procedure it is necessary to follow the following points:
1) Set a transmission power other than AUTO (for example the maximum power of 14 dB)
2) Forcing a communication in the radio sensor (pressing the IN3 pairing button)
3) Set the transmission power back to AUTO
4) Forcing a communication in the radio sensor (pressing the IN3 pairing button)
At this point the procedure for calculating the optimal transmission power will begin.
FAIL MODE
LAST VALUE = In case of sensor fail (communication timeout) the gateway keeps the last values sent
by the radio sensor
LOAD FAIL VALUE = In case of sensor fail (communication timeout) the gateway loads the fail values
FAIL TIMEOUT [x 30s]
Sets the fail time after which, if there has been no communication, the sensor is considered to be in a fail
state. Sets this time so that it is always greater than the sensor send time (SEND TIME).
FAIL VALUE “CNT0/ANG0”, “TEMP”, “HUMIDITY”, “INPUT0”, “INPUT1”, “INPUT2”, “INPUT3”
Sets the value to load in case of fail in the respective variable

INHIBITION TIME [min]
Sets whether or not to enable the inhibition for inputs IN0 and IN1 when they are configured as "alarm" (on
event). Any event that occurs before this time has expired from the previous one is ignored. If enabled, it is
possible to choose an inhibition time between 5 and 75 minutes.
An event that occurs before the inhibition time has expired reloads the inhibition time. For example, if the
inhibition time is 5 minutes and a new event occurs after 4 minutes, the inhibition is reset for another 5
minutes.
FIRMWARE UPDATE SECTION4.3.
The “Firmware Update” section allows you to update the device firmware in order to obtain new functions.
ATTENTION!
NOT TO DAMAGE THE DEVICE DO NOT REMOVE THE POWER SUPPLY DURING THE FIRMWARE
UPDATE OPERATION.
LOCAL TIME SETUP SECTION4.4.
Allows you to set the current date/time in case it is not possible to access the NTP servers.
The date is now kept for a few days even when the device is not powered.
