TD 269 OPERATING MANUAL
OXYGEN OPTODE 4330, 4831, 4835

Example of text file:
// Set sampling interval to 30 seconds
Set Passkey(1)
Set Interval(30)
Save
Get All
NOTE! The last line, Get All, reads out available properties for the sensor.
The first line is a comment line that is disregarded by the sensor. Strings starting with either ‘
//
’ or ‘
;
’ are
ignored by the software, and do not produce errors or acknowledgements.
When sending text file the sensor can be awakened from sleep mode by sending a string of comment
leads characters:
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// Wake up test
Get All
This will provide time for the optode to wake up and be ready before the next string appears. Note that
higher baud rates might require more lines of ‘/’ to provide sufficient delay. Communication wake up will
normally require less than 100mS.
5.7 Sensor Configuration
The sensor configuration consists of sensor settings and customized presentation of data. Refer Table
1-2 for a list of all sensor properties and the input format; below follows a description of the properties that
are typically set by the user prior to a deployment (RS232 application). Description of properties regarding
the sensing foil and calibration are given in CHAPTER 6 .
The
Mode
property is used to set the operation mode. Available modes are AiCaP, Smart Sensor
Terminal, AADI Real-Time and Analog Output.
•
Set
Mode
to
‘AiCaP’
when connected to AADI SeaGuard or to a SmartGuard logger that
automatically detects and recognices the sensor on CANbus(AiCaP).
•
Set
Mode
to
‘AADI Real-Time’
for use with AADI Real-Time Data Collector or third party
software that can handle XML based protocol
•
Set
Mode
to ‘
Smart Sensor Terminal’
for a simple ASCII command string based protocol when
connected to PC or third party serial interface
•
Set
Mode
to ‘
Analog Output’
when interfacing 4330 or 4835 sensors to optional Analog 0-5 V, 4-
20 mA adaptors, or enabling the build in analog output of the 4831
Note! As default the 4330 and 4835 sensors are set to AiCaP communication while 4831 is set to
Smart Sensor Terminal (RS232). Please select the correct Output according to which type of
logger/interface you plan to use.
