YSI 9600 - Manual (Page 49)

NOTE CAREFULLY: When interfacing your PC to the 9600 to perform data uploads and quick views as
described above, you have in no way affected the actual study which is presently in progress. Thus, there
is no need to restart the study after performing these operations.
5.4 STOPPING THE DEPLOYMENT
To stop a deployment, interface to the deployed 9600 with your PC which is running NUview software to
generate the active deployment screen as shown below left. Click on the Stop Deployment selection to show
the display below left that requires you to confirm the Stop Deployment command in order to prevent
accidentally terminating the study during field interfaces. To stop the deployment click “Yes” and the
deployment will be stopped as evidenced by a return to the Start Deployment display.
5.5 DEPLOYING THE 9600 WITH A DATA COLLECTION
PLATFORM
5.5.1 INTRODUCTION AND METHOD OF OPERATION
The most efficient method of communication for use of the 9600 with data collection platforms (DCPs)
made by a variety of manufacturers is the SDI-12 protocol and the ability to utilize this protocol is built into
the 9600 firmware.
SDI-12 is an industry-standard serial digital interface bus. The bus was designed to allow compatibility
between data collection devices and sensors of various manufacturers.
Running the 9600 in SDI-12 mode requires it to be connected to a SDI-12 master device or, in this specific
application, a data collection platform. These DCPs provide the commands necessary to communicate with
the 9600 in SDI-12 mode. For complete SDI-12 technical specifications please contact:

When a 9600 is set up for this application, the external DCP requests data from the 9600 at preset intervals.
The DCP then logs the data that is returned from the 9600 in its own internal memory for later download or
