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.

IO Server WXT520.png

Communication

Connect the 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.

Select the ASCII protocol and uncheck the "Polling only" option, so that automatic transmission is enabled. If the "Response with CRC" option is enabled, the WXT520 driver will check the CRC in received messages and discard messages with CRC errors.

The composite message transmission interval should be set to no more than 30 seconds, otherwise the driver could be occasionally restarted due to the intervention of the keep-alive watch-dog.


IO Server WXT520 configuration.png

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 UISET actions
false disable UI support
altitude 0 integer number 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.

Datapoints

All measured values returned as datapoints use the units as set in the WXT520. The unit is not returned in the datapoint value.
