9.354 Mesa-WSWD

This page describes the device driver and the device window for the Mesa-WSWD device. This device reads the wind speed and direction values from the Mesa WSWD Sonic Anemometer.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

--- Wind measurement.
--- The faults page.
--- The device info page.
--- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the RX8200.

parameter	description
address	The device address (or ID) as 2 character ASCII string. factory default of WDWD is 00
northOffset	Value for North Correction, changes will be written to EEPROM
Serial	Remember to set the line parameters for the serial interface to 38400,N,8,1 , no handshaking. (default)

Remarks

You need to configure the sensor to wait for a request command. It works not if the sensor is configured for Free-running Telegram Output.
It is recommended to use RS422 (4wire) serial connection. Unit should be configured with command 16 to full duplex.
