Section 4 Set up sensor and verify operation
Set up the hardware and install the software to make sure that the 25plus functions
correctly before deployment. Make sure that the sensor is connected to a power supply
and PC through the serial connector on the supplied cable. Most PCs no longer have
serial ports, and a serial-to-USB adapter is necessary. Make sure that the USB driver
software is installed on the PC so that there is communication between the sensor and
the PC.
1. Install the Seasoft V2 software from the manufacturer-supplied CD or the
manufacturer's website.
2. Remove the dummy plug from Y-cable to the sensor at connector J7.
3. Connect the I/O cable to the sensor and to the PC and a power supply (14–20 VDC).
4. Supply power to the 25plus.
5. Double-click on SeatermV2.exe to start the launcher.
a. Install SeatermV2, the terminal program launcher
b. Install Seaterm AF, the terminal program for autonomous water sampler setup
c. Install Seasave V7, real-time data collection
d. Install SBE Data Processing, the software to process collected data.
If this is the first time the software is opened, a Serial Port Configuration window
opens. The software automatically connects at the default baud rate of 9600 but will
try others if necessary. The software automatically looks for the serial port number of
the connected sensor.
6. At the Instruments menu item, select the software version associated with the
communication protocol of the sensor.
7. Push OK to close this window. The main window opens. The area on the left shows
available commands. The large area on the right shows commands and the
responses from the sensor to those commands.
8. To take a sample, enter TS. The display shows all 8 voltage channels, and will not
show serial sensor data.
