Xylem H-3531 FlashLite - Manual (Page 69)

H-3531
SDI-12 Command and Response Protocol 5-31
5.23 Extended “XTEST”
This command is used for installation or production testing and requires the use of a H-4191
Sidekick interface and a PC. This command causes the H-3531 FlashLite™ to transmit
unsolicited real-time data for testing purposes. The test mode is used to help troubleshoot the
installation by providing a continuous readout of pressure data. This is not compliant with the
SDI-12 specification and is not used with data loggers. To activate the test mode, send the
command “aXTEST!” from the PC. The H-3531 FlashLite™ will enter the test mode and make
continuous measurements. The test mode is exited by sending a break or any new command on
the SDI-12 bus. It may take a few tries to exit if the command is sent at the same time data is
being sent from the H-3531 FlashLite™. Removing power from the H-3531 FlashLite™ also
causes it to exit this mode.
Format:
SensorAdr + Stage + Pressure + Temperature +RawPressure (counts) + RawTemperature (counts)
“XTEST” displays the following data:
0: +1.202 +3.222 +23.0 +12345 +67890
0: +1.212 +3.232 +23.0 +12345 +67890

5.24 Extended “XDEF”
This command is used to set all the user settings back to factory defaults. This is useful in
troubleshooting when nothings seems to be working.
5.25 Extended “XCFG”
This command is used for installation or production testing and requires the use of a H-4191
Sidekick interface and a PC. This command returns the current configuration of the H-3531
FlashLite™.
“XCFG” displays the following data:
