Digital Matter Hawk manual

Calculus supports a variety of applications using of a Digital Matter Hawk module. Depending on the application, the below for each application:

• software calibration for the Hawk module;
• sensors, for example: water sensor, diesel sensor or adblue sensor;
• number of physical connections to the Hawk module.  

1.1. Water meter: Reed switch

• Green cable → I/O7 DIN1
• White cable → VIN

1.2. Watermeter:H2Q

• Red cable → I/O7 DIN1
• Blue cable → GND
• Black cable (Battery) → GND

1.3. Ratiometric sensor: BD Sensor 5V

• White cable (Power supply 5 V) → I/O2 +VBOOST OUT
• Brown cable (GND) → I/O6 SWGND
• Green cable (Data) → I/O1 AIN1

1.4. Ratiometric sensor: Huba sensor 3.3V

• Brown cable (Power supply 3.3 V) → I/O5 +3.3 V Out
• White cable (GND) → I/O6 SWGND
• Green cable (Data) → I/O1 AIN1

1.5. Ratiometric sensor: Keller sensor 3.3V

• Black cable (Power supply 3.3 V) → I/O5 +3.3 V Out
• White cable (GND) → I/O6 SWGND
• Red cable (Data) → I/O1 AIN1

1.6. 4-20mA sensor

• White cable (Voltage) → I/O2 +VBOOST OUT
• Brown cable (4-20mA) → I/O9 4-20mA

1.7. 4-20mA sensor and Ratiometric sensor

Ratiometric (Diesel tank)

• Green cable (Data) → I/O1 AIN1
• Black cable (Voltage) → I/O5 +3.3V OUT
• Brown cable (GND) → I/O6 SWGND

4-20mA (AdBlue tank)

• Black cable (Voltage) → I/O2 +VBOOST OUT
• Brown cable (4-20mA) → I/O9 4-20mA

1.8. 1-wire

• Green cable (Voltage) → I/O5
• White cable (Data) → I/O 8
• Brown cable (GND) → GND

Remove the strip to activate batteries.

When the Hawk module is inserted, the LED next to the GPS antenna will blink briefly. If the LED does not flash, the module still needs to be reset. This is done by removing the batteries for at least five minutes to drain any residual charge. Then insert the batteries back.

1. 1. Place the lid on the gateway and squeeze it gently close it. The foam in the lid will press against the batteries press down and hold them firmly in place when the unit is flipped over.
   2. Tighten the 8 screws evenly. On initial assembly, the screws may be quite stiff.

The gateway can be mounted with screws, bolts, cable ties or industrial adhesives to the object to be tracked.

Please note the following when choosing a mounting point:

1. Reduce the chance of accidental crushing or detachment.
2. Increase GPS and cellular reception by mounting the gateway in a good location mounting;
3. Provide adequate ventilation.

Every twelve hours, the Hawk module attempts to obtain a GPS fix fix. Sometimes it fails to retrieve this fix when the module is still attached under an iron lid.

Therefore, the most optimal situation for the Hawk module to obtain the GPS fix on is therefore when it can "see" the outside air. You can try to get a new fix get a new fix by resetting it. You do this by removing the batteries for at least five minutes. When you then put them back in, the Hawk will try to obtain a new fix.

After installing the gateway and sensor in the tank, you should fill the tank completely. To calibrate a tank, first go to the dashboard of the corresponding tank. At the bottom of the dashboard you will find the "Max Raw Sensor data in Period" widget. When the tank is completely full, use this value to calibrate the tank.

At the top of the dashboard, you will see the name of the tank, followed by an arrow icon. Click on this icon.

You will be redirected to the "Edit asset" page. At the top you will see several tabs, including "Metadata." This is the page you need.

On this page you can enter values for different variables. The most important variables to calibrate a tank are "TankLiter" and "Tank100pct".

At "Tankliter" enter the maximum volume of your tank in liters, for example 300. At "Tank100pct" enter the value you see in the "Max Raw Sensor data in Period" widget on the dashboard. The value you enter here is the value you obtain when the tank is completely filled is. Be careful not to include the comma or period.
