Parameter
Default Value
Profile-Specific Allowed Values
Description
com1_protocol 0 1)
6 = WS425 AB WAT11
Profile for serial port COM1
com2_protocol 0 6 = WS425 AB WAT11
Profile for serial port COM2
1)
The parameter has no protocol-specific default value. It is determined separately in the configuration code.
5.25.1 WS425 AB WAT11 Commands
When the WS425 AB WAT11 profile is selected, you can poll data using the following command:


Escape character ASCII 27H

WMT700 ID, for example, A
Response:


Start of text character (1 digit)

WMT700 identification character, for example, A (1 digit)

Wind speed (in meters per second) multiplied by 10. For example,
045 is 4.5 meters per second (3 digits).

Wind direction with two octal numbers for bit binary data, for example, corresponds to (7×8+3)/64×360 = 332 degrees
Missing Reading
The WS425 AB WAT11 message reports missing data as slashes (
/////).
5.26 SDI Profile (v SDI is a standard for interfacing data recorders with microprocessor-based sensors. The name stands for serial/digital interface at 1200 baud.
The SDI Support Group is an association of companies that produce and use SDI-12
products with the purpose of reviewing requests to enhance, clarify, or modify the SDI-12
architecture and that votes on proposed changes to SDI-12.
