Section 1 SBE 25plus quick start guide
This quick start guide gives the steps necessary to make sure that the SBE 25plus
operates correctly and collects data before it is deployed.
What's in the box:
• CD or memory stick—has software, calibration files, documentation
• Dummy plug and lock collar
• Data I/O cable to connect the sensor to a PC
• Spare hardware and O-ring kit.
1. Install the manufacturer-supplied software on a PC (refer to Set up sensor and verify
operation on page 13 for details.)
2. Connect the data I/O cable to the sensor and the PC and double-click on
SeaTermV2.exe to start the software.
3. Set up the sensor for deployment.
a. If necessary, make sure that all data stored in the sensor is transmitted to a PC.
b. Set the date and time and configure the data collection settings.
c. Send the DS and DC commands to verify setup.
4. Remove the yellow protective label from the plumbing intake and exhaust.
5. Deploy the sensor. For most applications, make sure the connector is at the bottom
(lowest point).
6. Immediately after the sensor is recovered from a deployment:
a. Use the software to turn off the sensor.
b. Flush the sensor with fresh water.
c. Keep the sensor out of direct sunlight between deployments.
7. Transmit data from the sensor to a PC. Refer to Transmit and convert data
on page 29 for details.
8. Refer to Recover 25plus from deployment on page 28 for details to prepare the
sensor for short- or long-term storage.

Notes:
• The Y cable from J7 connects to the pump and a data I/O power cable, so the system
can connect to a PC for setup and to transmit data, and to externally power the
25plus.
•Auxiliary sensors that draw more than 1 amp, even momentarily, must be
connected to J3 or J6. Refer to High current-draw sensor integration
on page 57 for details.
