3.7.5 Serial Interface Timing
Depending on the selected interface, the serial data interface timing is as follows:
WMT700 User Guide

42

Interfaces RS, RS, RS The figure below shows timing when WMT700 is polled in the measurement mode.
Figure 18 Timing for RS, RS, and RS Interfaces
The response delay t is user-configurable. In the configuration mode, some commands have a longer response delay.
• SDI-12 interface The timing is compliant with the SDI standard. For the complete
SDI-12 standard text, see www.sdi-12.org
3.8 Analog Output
Analog outputs are either enabled or disabled, and the output settings are preconfigured at the factory according to your order. In analog output operation WMT700 takes measurements according to the configured averaging time and synthesizes the analog outputs of wind speed and wind direction with an update interval of 0.25 seconds.
You can use configuration parameters to change the analog output type, WMT700 scaling or save power by disabling the analog output functionality.
WMT700 provides the following analog outputs:
• Aout1 for wind speed data
• Aout2 for wind direction data
To emulate the WS425 analog output, choose voltage output, frequency output, and potentiometer.
