Error Messaging/Text Messages
WXT510 sends a text message when certain type of errors occur. This
function works in all communication modes except in the SDI-12 mode.
You may disable error messaging by using the supervisor message aSU,
S=N, see
Changing the Settings on page 110 .
Examples:
0R1!0TX,Unable to measure error<cr><lf> (request of wind data
while all the wind parameters were disabled from the wind message)
1XU!0TX,Sync/address error<cr><lf> (wrong device address. Ask
the correct address with ? or ?! command.
0XP!0TX,Unknown cmd error<cr><lf>
Data messages are not in
expected format. The communication protocol
may not be the one you want. Check the communication
protocol of the device by using
the Vaisala Configuration Tool or
any terminal with command
aXU,M! (SDI-12)
aXU,M<cr><lf> (ASCII/NMEA)
and change it if needed. See
Chapter 6, Communication
Settings, on page 45
.
Some parameters are missing
from the data messages. The formatting of the data
messages is not what you
expect. Format the data messages of the
concern by using the Vaisala
Configuration Tool or any
terminal program. See
Chapter
8, Sensor and Data Message
Settings, on page 93
.
An error message as a response
to a command. See section Error Messaging/
Text Messages on page 119 .
See section Error Messaging/
Text Messages on page 119 .
WXT510 keeps sending the
message "TX Sync/address
error". The polling address and
WXT510 address do not match.
The WXT510 is on an RS-485
bus with other polled devices
and Error Messages are
enabled. Set correct address either for the
WXT510 or to the polling
request.
Disable the Error Messages with
the command aSU,S=N <crlf>.
