3rd Party Sensor
The GA Weather Station is a 3rd Party sensor - the advice given below is general. Specific guidance on installation and usage should be obtained directly from the manufacturer. The instructions below are based on a sensor tested at the time of article writing - things may change.
IO Card
Ensure a plug-in IO card with an RS-485 interface is fitted to the Hawk. Currently the only card with this interface is the RS-1 card.
Wiring
| GA Station | Connect to |
| Red (V+) | 7-30V DC Power (Separate to Hawk) The Station cannot be powered via the Hawk due to it's high current requirement and need to remain permanently powered |
| Black (GND) | GND |
| Yellow (RS485 A) | Hawk IO 4 (RS485 A) |
| Green (RS485 B) | Hawk IO 3 (RS485 B) |
Parameters
RS485 Action Parameters
- Select GA Station as the Sensor Type
- Choose an Analogue Offset.
- 7 separate readings are reported by the weather station.
- The offset defines where the first reading goes, with the others in following analogues
- In the example below this would be readings in analogues 12,13,14,15,16,17 and 18.
- 7 separate readings are reported by the weather station.
Task Parameters
Ensure the RS485 action you have configured above is set as an action of the task.
Output/Conversion
With the above parameters, the output would be:
| Value | Type | Analogue | Units | Conversion Example |
| Temperature | INT32 | Analogue Offset Value | °C * 100 | 800 = 8°C |
| Humidity | UINT16 | Analogue Offset Value + 1 | % * 100 | 5000 = 50% |
| Wind Speed | UINT32 | Analogue Offset Value + 2 | cm/s | 500 = 500cm/s = 18km/h |
| Wind Direction | UINT16 | Analogue Offset Value + 3 | Degrees | 127 = 127° |
| Pressure | UINT32 | Analogue Offset Value + 4 | Pa | 10021 = 10021 Pa = 100.21hPa |
| Precipitation | UINT32 | Analogue Offset Value + 5 | mm | 120 = 120mm |
| Illuminance | UINT32 | Analogue Offset Value + 6 | mW/mm² | 1000 = 1000mW/mm² |
