QUICK INSTALLATION GUIDE
1.1 Introduction
WSSFC-DI is a Sigfox-Ready node with digital inputs to detect logic status 0/1 OR counting pulses from the water meter, gas meter, power meter, proximity sensor, limit switch, machine output, pressure switch… Ultra-low-power design and smart firmware allow the sensor to run on a 2 x AA battery 1.5V for 10 years with one update per day. It can support Sigfox Zones RC1, RC2, RC3c, and RC4.
How the sensor connect to system?
System components:
The end nodes are Sigfox-Ready Sensors or Actuators;
The Sigfox Base Stations (installed and operated by Sigfox Operator);
The Sigfox Back-End (Operated by Sigfox Company);
The Application Server is the destination software users want to utilize the data from/to Sigfox-Ready sensors/ actuators.
How do you set up the Sigfox-Ready device and get its data to the Application Software? Please follow these steps:
Contact the local Sigfox Operator to sign a Data plan contract. You will be provided an account;
Log in to the Sigfox Back-end by your own account then add the Sigfox-Ready Devices. Please follow the guidelines of Sigfox back-end;
Configure the callback or data forwarding from the Sigfox Back-end to the Application Software. Please follow the guidelines of Sigfox back-end;
Once the payload is on the Application server, decode data from Payload. Please check Section 1.9 for the Payload document.
1.2 Application Notes
For Applications
Electric Meter Reading, Gas Meter Reading, Water Meter Reading, Production Monitoring, Facility Monitoring, Flood Monitoring, Level Monitoring, Machine Health Monitoring, Safety Monitoring
Notes
Accept the dry-contact output or voltage output with a max of 3.3V;
Consider the shortest signal cable to avoid noise, especially for high-speed pulse applications;
Recommend using the shielded cable with twisted pairs;
Take note of the signal's duty cycle to meet this device's requirement.
1.3 When does device send Uplink messages?
The device will send uplink messages in the following cases:
Case 1: After power-up in the 60s, the device will send the first message called START_UP. The payload will tell the user the HW version, FW version, and current configuration of the device;
Case 2: Then, in every interval time (pre-configured), for example, 10 minutes, it will send the message called CYCLIC_DATA. The payload will tell the user the following data like measured values, battery level, and alarm status...
To change the cycle of data sending, you can change the value of the parameter: CYCLIC_DATA_PERIOD (default is 600 seconds).
Case 3: In PULSE COUNTING mode, if COUNT_ALARM_ENABLED=1, the device will send ALARM message immediately when the resettable counter of channel 1 higher than the threshold value (parameter COUNT_THRESHOLD). After sending, the resettable counter of channel 1 will be reset to Zero for counting again for the next alarm. In STATUS DETECTION mode, when digital input device change status from 0 to 1 or from 1 to 0, the device will send the ALARM message immediately.
Case 4: During the commissioning, testing, or calibration sensor, the user can force the device to send the uplink message to get the data immediately. This message is called FORCE_DATA. The payload will provide data like raw measured value, scaled measured values, battery level, and alarm status... It can be forced by applying the magnet key on the reed switch in 1s;
Case 5: If users want to change the configuration immediately, they don't need to wait until the next cyclic data-sending message; instead, they can force the device to send a special uplink message so that the device can get the new downlink message. This uplink message is named PARAMETERS_UPDATE. It can be forced by applying the magnet key in more than 5s.
Case 6: The HEART_BEAT uplink message will be sent once a day (the default setting can be changed in configuration) to allow the Sigfox back-end system can send the downlink message for changing the configuration of the sensor. Please refer to the downlink section for more details. The uplink payload will tell the user the HW version, FW version, and current configuration of the device;

ADVANCED GUIDE
3.1 Principle of Operation
Principle of Operation for Device WSSFC-DI | FW1
The Daviteq Sigfox-Ready DI has 02 digital inputs with low voltage 3.3V. The Firmware can run in 2 modes:
Logic detection: to detect the status of digital input. It applies to both channels;
Pulse counting: to count the pulse of channel 1 only;
What are the primary output values?
Logic status of channel 1: parameter in the payload is STATUS_DI1
Logic status of channel 2: parameter in the payload is STATUS_DI2
Non-resettable counter for channel 1: Non-resettable counter values for the Digital Input 1. The counter only operate in Counting mode. This counter is not be reset if power/battery is off. Parameter in the payload is NRS_COUNTER_DI1
Resettable counter for channel 1: Resettable counter values for the Digital Input 1. The counter only operate in Counting mode.
Sensor operation mode: operate in counter mode or status detection mode. If OPERATION MODE equal 6, the sensor operate in Counting mode to count the output pulses with max frequency 2 Hz for digital input 1 only. If OPERATION MODE equal 7, the sensor operate in Status mode to detect the logic status 0/1 with max frequency 0.33 Hz.The parameter in the payload is OPERATION_MODE.
Alarm Status: Alarm when RS_COUNTER_DI1 > COUNT_THRESHOLD in counter mode OR when input channel 1/2 change the status from 0 to 1 and vice versa in status mode. This parameter in the payload is ALARM
Please check the payload document for more details.
What are the secondary output values?
Below output values are useful for device maintenance and troubleshooting.
Battery level (%), to understand the remaining capacity of the battery: parameter in the payload is BATTERY_LEVEL. Note: To get the accurate battery_level indication, please configure the battery type by Downlink type 5 or via offline cable to the parameter name BATTERY_TYPE. The default type is Primary battery. For Solar powered version, please configure to Rechargeable battery type.
Sensor error code, to understand whether the sensor is working properly or not: parameter in the payload is HW_ERROR
Sensor current configuration, to understand what is the current setting of the sensor: parameter in the payload is LATEST_SIGFOX_DOWNLINK
Hardware version and Firmware version, to understand the product version: parameter in the payload is HW_VERSION and FW_VERSION
Principle of operation
Most of the time, the device will be in sleep mode. However there is a micro process to monitor the status of digital input to detect the logic changing or pulse counting.
There are 02 operation modes:
Logic Detection: parameter OPERATION _MODE = 7
Pulse Counting: parameter OPERATION _MODE = 6
In LOGIC DETECTION mode:
The device will send ALARM message when the status changes from 0 to 1 or from 1 to 0.
If status does not change, the device will check the timer to reach the Cyclic_Data_Period to send the CYCLIC_DATA message;
In PULSE COUNTING mode:
If parameter COUNT_ALARM_ENABLE = 1
That meant the device will send ALARM message when the resettable counter higher than the threshold value (parameter COUNT_THRESHOLD). After sending, the resettable counter will be reset to Zero for counting again for the next alarm.
If the resettable counter <= COUNT_THRESHOLD, it will check the timer to reach the Cyclic_Data_Period to send the CYCLIC_DATA message;
If parameter COUNT_ALARM_ENABLE = 0
The device will check the timer to reach the Cyclic_Data_Period to send the CYCLIC_DATA uplink message;
In special case, the user want to change the innitial couting value of the counter, they can use the Downlink Type 5 command to write data for below parameters:
INIT_VAL_FOR_NRS_COUNTER_DI1: innitial value of Non-resettable counter
INIT_VAL_ENABLE: write 1 to enable the writing process of that innitial counter value.
Principle of Operation of Sensor part (if available)
With version DI-12, the microprocessor of the master device (wireless device or wired device) will read the status of digital input ports in a predefined time interval for battery saving. Therefore it can only count the Pulse with a max 2Hz frequency, and apply for the 1st channel only.
With version DI-12H, the digital input port will connect to an internal timer/counter of the microprocessor for high-speed counting. Therefore it can count the pulse up to 1 kHz, for both 2 channels.
