Problem
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)
• Check wiring connections.
One-way
• 'Acquire' the sensor with the ResponseONE CONFIG program (see section 6.2).
communication
• Change output mode to RS-485 full or half duplex, or RS-232.
Status codes
• Status codes other than 00 (or 'A' in NMEA mode) mean there is an error. See

poll command
• 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!'
• 'Acquire' the sensor with the ResponseONE CONFIG program (see section 6.2)
Direction is
• If compass is off, make sure junction box is facing south.
incorrect
• 'Acquire' the sensor with the ResponseONE CONFIG program (see section
• 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
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)
