The transmitter sends a text message when certain type of errors occur. The function works in all communication modes except in the SDI-12 mode. You can disable error messaging by using the supervisor message aSU, S=N.
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>
0xUabc!0TX,Use chksum CCb<cr><lf>
(wrong checksum applied to the 0xU command)
| Text message identifier (NMEA 0183 v3.0 protocol only) | Text message | Definition |
|---|---|---|
| 01 | Unable to measure error | The requested parameters are not activated in the message. Check the parameter section fields. |
| 02 | Sync/address error | The device address in the beginning of the command is invalid. Ask the device address with the command ?! (SDI-12) or ?<cr><lf> (ASCII and NMEA) and retype the command with the correct address. |
| 03 | Unknown cmd error | The command is not supported, use the correct command format. See Retrieving data messages. |
| 04 | Profile reset | Checksum error in configuration settings during power-up. Factory settings used instead. |
| 05 | Factory reset | Checksum error in calibration settings during power-up. Factory settings used instead. |
| 06 | Version reset | New software version in use. |
| 07 | Start-up | Software reset. Program starts from the beginning. |
| 08 | Use chksum xxx | Given checksum not correct for the command. Use the proposed checksum. |
| 09 | Measurement reset | The ongoing measurement of all the sensors interrupted and started from the beginning. |
| 10 | Rain reset | The precipitation sensor counter reset. |
| 11 | Inty reset | Precipitation sensor intensity counter reset. |
| If you use a WXT530 transmitter on an RS-485 bus with other polled devices, you must disable error messaging with the command 0SU,S=N<crlf>. |
