APPENDIX C: TROUBLESHOOTING
Problem
Solution
No Output
• Check input voltage at sensor (10 – 30 VDC).
• Check wiring connections.
• Verify serial settings (baud rate, 1 stop bit, 8 data bits, no parity, no flow control).
• ‘Acquire’ the sensor with the
ResponseONE
CONFIG
program (see section 6.2)
and verify setup mode.
One-way
communication
• Check wiring connections.
• ‘Acquire’ the sensor with the
ResponseONE
CONFIG
program (see section 6.2).
• Change output mode to RS-485 full or half duplex, or RS-232.
Status codes
other than 00
appear
• Status codes other than 00 (or ‘A’ in NMEA mode) mean there is an error. See
‘Status Codes’ section for details.
No response to
poll command
• Check power supply.
• Check wiring connections.
• Verify serial settings (baud rate, 1 stop bit, 8 data bits, no parity, no flow control).
• Verify sensor address (if the sensor’s address is ‘0’, then the poll command is ‘0M!’
in SDI-12 mode and 'M0! in ASCII Polled mode.).
• ‘Acquire’ the sensor with the
ResponseONE
CONFIG
program (see section 6.2)
and verify setup mode.
Direction is
incorrect
• If compass is off, make sure junction box is facing south.
• ‘Acquire’ the sensor with the
ResponseONE
CONFIG
program (see section
6.2) and verify settings. Enable and calibrate compass if needed, enter compass
declination, and set the wind direction offset (default is 0000).
• Turn compass on and calibrate if needed.
Status codes for ASCII output are hex values added together before output (a status code of 03 would be a
code of 01 and 02). NMEA only allows for ‘acceptable’ or ‘void’ data. SDI-12 does not show a status code.
Status Code
Meaning
00
Valid data
01
Transducer path A blocked or dirty, clear blockage and clean transducers
02
Transducer path B blocked or dirty, clear blockage and clean transducers
04
Transducer path C blocked or dirty, clear blockage and clean transducers
A
NMEA data acceptable (NMEA wind data only)
V
NMEA data void (NMEA wind data only)
