WARNING: DO NOT connect the Communications Saddle to

your PC before installing Data Manager. The Communication

Saddle drivers MUST be installed prior to connecting it to your

PC. The drivers will install automatically during the Data

Manager installation. The first time the saddle is connected to

the PC, you may have to walk through a couple of installation

wizards. For detailed instruction, please refer to the Readme file

located on the CD that was included with your instrument.

A PC will recognize the Communications Saddle (saddle) as a YSI water quality

instrument with or without the Pro Plus installed in the saddle.

to connect the saddle to a Pro Plus, simply align the saddle to the oval section on

top of the instrument and push it down to snap it in place (Figure 6).

Figure 6. Locate the oval alignment groove at the top of the instrument

and inside the saddle. Insert the saddle into this oval groove. Press the

saddle towards the back of the instrument until it snaps into place.

Connect the USB cable to the top of the saddle and to a USB port on the PC.

once Data Manager is launched, the program will recognize all saddles with

instruments connected to the PC.

the instrument will be powered through the saddle and USB connection when

connected to the PC. However, the instrument must still have batteries installed

in order to keep the date and time correct when powering the PC off at night.

Make sure the instrument is turned off first, then turn off the PC to keep the

instrument from running all night on the batteries. If you power it off and

power off the PC the instrument will keep the correct date and time if it has

batteries installed. If batteries are not installed, the instrument’s date and time

will not remain correct and will need to be reset each morning.

ManaGe loGGed data

Data that has been logged to the Professional Plus can easily be uploaded to the

PC via the provided USB saddle. You can upload sensor data, GLP files, site lists,

and instrument configuration files individually or all at once. After connecting

the instrument to the PC via the USB saddle and cable and launching Data

Manager, click the Retrieve Instrument Data tab. Click on the Instrument’s

Unit ID you would like to retrieve data from, then select the files you would like

to retrieve and click Start.

once the sensor data is uploaded to the PC, you can graph and view tabular data

by instrument Unit ID, date/time, site name, and/or folder name. this allows

you to configure the report according to your needs. You can choose to view

all data from all instruments, or select a certain date/time range for only a few

specific instruments, there are multiple ways to view the data. once the report

has been defined, you will be able to print the graph and/or export the table.

Data Manager takes information management one step further and allows

you to delete specific points instead of entire files. this allows you to clean up

data that is no longer needed or that may have been collected erroneously, for

example, when the sensor was out of the water. If you can not delete data due

to regulation and compliance purposes, Data Manager has the solution. While

viewing logged data or real time data, you have the ability to ‘tag’ individual data

points with comments.

In addition to sensor data, you will be able to view GLP files, site lists, and

configuration files that have been uploaded from the instrument. these can be

printed and exported as well.

real tIMe studIes

Data Manager allows you to view real time data on the PC.

After selecting your instrument, click the Real Time Instrument Data tab.

Next, input your sample interval, site/folder name, select the parameters you

wish to view and click OK. You must click Start on the next screen to begin

your real time study. Choose to hide the table or graph by unchecking the

box next to these options. Click Stop, then Edit Setup to change the Y-scale

min/max of the graph, to select different colors, or to name your graph. Add a

comment to a data point by clicking in the comment field of the table next to

the data point. You may also Print the graph and Export the data for viewing

in another program.
