The VAISALA WXT520 is a small and lightweight transmitter that offers six weather parameters in one compact package. WXT520 measures wind speed and direction, precipitation, atmospheric pressure, temperature and relative humidity.
The HSYCO WXT520 driver supports the RS-232 and RS-485 serial interface version, with the ASCII automatic protocol on the WXT520.
Contents
Communication
Connectthe WXT520 to HSYCO through a direct serial connection or a supporter TCP/IP to serial gateway.
The default RS-232 parameters are:
| Baud rate | 19200 |
| Data bits | 8 |
| Stop bit | 1 |
| Parity | none |
| Flow control | none |
WXT520 configuration
The WXT520 must be configured to automatically send all relevant measured data to the serial port using its proprietary ASCII protocol.
HSYCO Configuration
Add a WXT520 I/O Server in the I/O Servers section of the Settings and set its parameters:
Communication
- Comm ID: select the comm port connected to the device.
High Availability
- Shutdown when inactive: defaults to true.
Options
| ID | Default | Values | Description |
|---|---|---|---|
| gui | false | true | enable support for the UI object, UISET actions and USER commands |
| false | disable UI support | ||
| altitude | 0 | n >= 0 | the station's installation altitude above mean sea level.
This optional parameter is used to convert the measured local atmospheric pressure to mean sea level pressure (MSLP). The conversion function takes into account the altitude and local temperature. If this paramter is not set or set to 0, the measured pressure value will be returned unmodified. |
