YSI 6200 DAS USER Manual
The water quality sensors include water temperature, conductivity, dissolved oxygen, pH, ORP, depth/level, turbidity, nitrate, ammonia and chloride.
The system includes a field station (6200 DCP), which houses a powerful data logger and connects to any of the water quality or meteorological sensors you choose. The data logger uses a 32-bit
â
microprocessor with up to 1 megabyte of data storage memory. Windows
-based EcoWatch DCP software functions to interrogate the data logger and display real-time results in time stamped table format. Alternatively, you may request data stored in the field station less frequently to conserve power. The software also provides autoconfiguration capability during setup and calibration and includes a powerful plotting package for further analysis of the recorded data.
There are four options for communication between the field station and the base station computer. They are (1) direct link via RS-232 serial communication, (2) phone modem communication, (3) cellular phone communication, and (4) UHF radio communication.
There are three options for powering the field station. They are (1) rechargeable lead acid battery (12 volt, 12 Ah) mounted inside the NEMA 4X field station enclosure, (2) solar panel that charges the battery described in 1 above, and (3) 100/120//220/230-240 V~, 50/60 Hz power. The battery is installed in all versions. It is required in the solar setup and serves as a backup in the AC power setup.
The 6200 DAS comes to you configured to your order, including all interface cables. You may need to provide additional wiring and junction boxes if you are powering the field station with AC power. You may need to provide mounting supports for the main enclosure and various accessories, such as sensors, antennas and the like. Most of the mounting hardware you need comes with the 6200 system, but some may not be appropriate for your particular mounting configuration.
The 6200 DAS specifications are described below. You may refer to Appendix A for specifications of specific sensors and accessories. In addition, the accessory manuals provided with this manual package should be helpful.

Getting Started

2.1 Unpacking and Inspection
Inspect the outside of the shipping carton(s) for damage. If damage is detected, contact the carrier immediately. Remove the instrument from the shipping container. Be careful not to discard any parts or supplies. Confirm that all items on the packing list are present. Inspect all assemblies and components for damage. The basic 6200 DAS is shipped with the following major components. Some differences may occur based on the configuration you ordered.
Data Collection Platform with barometer, communication and power accessories installedBattery for powering remote station (packed separately)Meteorological Suite (WS, WD, RH, AT) with 4.6 m cable, or 13.7 m cablePyranometer (3 m cable) or Pyranometer with CE approval (3 m cable)Rain Gauge, ISCO 674 (4.6 m cable) or Rain Gauge with heating element (4.6 m cable)Sonde with appropriate sensors, cables, adapters and reagentsAntennas (if applicable)Radio Base Station (if applicable)
If you ordered a sonde with reagents, the reagents may be shipped separately. See Appendix D for a complete list of accessories.
If any parts are damaged or missing, contact your factory representative immediately. If you do not know from which dealer your 6200 DAS was purchased, contact YSI/Massachusetts. See phone/fax information below in the footer.
Save the original packing cartons and packing materials. Carriers typically require proof of damage due to mishandling. Also, if it is necessary to return any parts, you should pack the equipment in the same manner it was received. Maintaining original cartons and packing material is less critical once the system is installed and working
If the 6200 DAS components match the packing list and the components appear to be in satisfactory condition, proceed to the sections below.
WARNING!
To avoid severe personal injury or damage to the equipment...installation,
operation and service should be performed by qualified personnel who
are thoroughly familiar with the entir e cont ents of this manual.
The 6200 Data Acquisition System with EcoWatch DCPä is an integrated hardware and software package. Most of the hardware will be installed in the field. We will refer to this as the “field” location. The “base” location will refer to the site where the radio base station or modem connects to the computer loaded with EcoWatch DCP. We strongly recommend that you assemble the system “in-house” and functionally test it prior to beginning the field

2.3 Setting Up System Components for Checkout

In this section you will find instructions for checkout installation of your entire system in the laboratory or other temporary location of your choice. Field station and base station components will be in the same room for this initial setup and checkout procedure. Your setup may differ from the one described below since the 6200 DAS was ordered to your specification. Many steps are common to all setups, therefore simply skip sensor, communication and power setup instructions that are not relevant to your system. Section 5 will go into more details about setting up each sensor in the field.
The example 6200 DAS described below contains all of the standard meteorological sensors and one sonde with the most common water quality sensors. Initially we will use a “Direct Link” (RS-232) communication option and battery power to set up and check out the system in the laboratory. If a radio transmitter has been installed in the 6200 DCP enclosure, then it is very important to install the radio antenna. For this reason the radio and antenna have been shown in the diagram below. Begin by studying this diagram, then follow the step-by-step assembly and connection instructions. If your system includes a 6-series sonde, you may want to refer ahead to Section 2.4 for initial setup information.

Assuming that all shipping cartons have been opened and the equipment has been initially checked for damage, proceed by doing the following.
1. Place the 6200 Data Collection Platform enclosure on a work surface, leaving space for
accessories to be laid out and connected. Position the enclosure so that the bottom (connector ports) faces toward you. Next open the hinged cover, by releasing the two latches on the right side. Refer to the diagram below, and remember that the diagram may differ slightly from your unit based on the components you ordered.

2. If a radio is installed in the 6200 DCP enclosure, you should locate the field antenna that you
ordered and connect it to the antenna connector on the bottom of the enclosure.
CAUTION!
To avoid permanent damag e to the radio transceiver, connect the antenna befor e
powering the 6200 DCP or the radio base unit.
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-4
YSI 6200 DAS USER Manual
3. Unpack the battery and insert it into the battery slot (see Section 4.3 for details). The battery
connectors are different sizes. Connect the leads, red to positive and blue to negative. After the battery is connected, the 6200 DCP should beep for a few seconds as it boots up. The battery was charged at the factory and should function without problem for this test. Later we will check the battery voltage with EcoWatch DCP software.
4. For proper testing of the Meteorological Suite sensors, you should construct a makeshift
support or stand for this accessory. A 2” (5 cm) diameter rigid pipe secured to a base works well. (refer to Figure 2.1) Remove the Meteorological Suite main assembly from its packing carton. The propeller has been packed separately in the same carton. Remove the propeller, and use the finger-nut attached to the main shaft to secure the propeller to the main assembly. The molded lettering on the propeller should face out or away from the main assembly. Hold the front cone and slightly rotate the propeller to insure that it drops into the “cross” shaped channel on the cone. Finally tighten the knob on the main assembly with your fingers. Do not use excessive force. Connect this sensor to the 6200 DCP.
5. Remove the Rain Gauge from the packing carton. There is no assembly required. You may
want to remove the lid, which is an assembly containing a screen or grid and funnel. In order to functionally test the rain gauge in the lab, the tipping buckets need to be accessible. In the ISCO model, unlatch the base and gently remove the cylinder/funnel assembly. In the model containing a heating element, remove the lid/funnel by lifting it off. Connect this sensor to the 6200 DCP.
6. Remove the pyranometer from its packing carton and place it on a flat surface near the 6200
DCP. Locate the certificate and save this document. It contains a calibration constant that must be entered during the sensor setup routine in EcoWatch DCP. To perform the functional test you will need to remove the plastic cap that protects the light sensing surface. Also note that a small bubble level is permanently installed in the base of this unit. During field installation, this bubble should be used for proper installation. Absolute “level” is not critical during this initial setup. Connect this sensor to the 6200 DCP.
7. Remove the 6-series sonde from its packing carton. There are several models of sondes that
can be used with the 6200 DAS. Refer to Section 2.4 in this manual for a basic checkout setup. Note that this is not the complete setup and calibration procedure you would use for deployment of the sonde at a field station. EcoWatch DCP contains a menu related to sonde communication. More information for setup of the sonde is located in Section 3. Wait until section 2.4 to connect this sensor.
8. There are several options that you may use to initially establish a communication link
between the data collection platform and the PC-based EcoWatch DCP software. The simplest link at this point is the “Direct Link” using the RS-232 cable provided. Plug one end of this cable into the DB-9 COM port of the 6200 DCP and the other end to a COM port of the PC loaded with EcoWatch DCP.
Naturally, you will want to functionally check the 2-way radio link, the cellular modem link, and/or the phone modem link. Refer to Sections 6 and 7 for more information. For now,
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-5
YSI 6200 DAS USER Manual
however, use the direct link to functionally check your sensors, power source, and DCP in this laboratory setup.
Your setup as described above should now appear similar to the diagram below. Note that the Radio Base Station is not connected to the system at this point, as it will be checked later.

2.4 Setting Up a 6-Series Sonde for Checkout

If a 6-series sonde is not part of the system you ordered, proceed to Section 2.5.
Below is the procedure to unpack and set up a 6-Series sonde for 6200 DCP checkout. The
procedure does not include calibration of the sonde sensors. Other than temperature, the readings may seem unrealistic at this time. The objective is to familiarize you with specific sensor setup protocols, not to obtain accurate data.
For many sonde models you must physically install some of the sensors into the sonde bulkhead. You should refer to the sonde manual for details so not to damage the sensors.
CAUTION!
To avoid permanent damag e to the sonde, do not submerse the sonde in water during
this initial checkout.

YSI 6200 DAS USER Manual
When you remove the sonde from the shipping container, you will see that a probe guard protects the sensors. Unscrew the guard to determine the sensors installed. After checking and/or installing sensors, place the probe guard back in place to protect the sensors.
Sensors shown in this example are temperature, conductivity, dissolved oxygen and pH. It is important to know what sensors are installed for the purpose of correctly assigning sensors during setup.
Figure 2.4 600 Sonde, Probe Guard Removed
In order to setup your sonde, you must connect the sonde to your PC and communicate through EcoWatch DCP. The diagram below helps describe this connection.
In addition to the sonde, you need a cable. The cable may be a field cable permanently attached to the sonde or you may need to connect a separate field or cal cable to the bulkhead connector of the sonde.

may be needed to make the connection. The PC-end of the adapter is a DB-9 which is a typical COM port connector. If your PC has a DB-25 connector, you will need another adapter (25 to 9 pin).
Figure 2.5 Sonde to PC Connection
Identify your COM port, for example, COM 1, COM 2, etc. You need this information to establish communication between the sonde and EcoWatch DCP. If your COM port is not clearly marked, assume that it is COM1 for now. You can reconfigure for COM2 (or other COM port) if communication is not established during setup.

Once complete with this window click on OK. Now return to top line menu and click on Comm, then choose Sonde from the submenu. Select
your COM port and press OK. You will now see a window labeled Sonde – COM1. The # sign should appear (see below). Type in menu. When you press Enter, you will enter the main sonde menu. It will appear similar to the screen below. Any difference is related to the model of sonde you are using.
If you are unable to establish interaction with the sonde, make sure that the cable is properly connected, power is applied (e.g., 6038 Power Supply or other 12 VDC source), and that the COM port settings are set correctly. If you were unsure of your COM port number, reassign another port number and repeat the steps above.

The sonde software is menu-driven. Select a function by typing its corresponding number or character. It is not necessary to press Enter after a number/character selection. Use the 0 or Esc key to return to a previous menu. The mouse does not interact with the sonde menus.
NOTE
If a single keystroke yields no response on the screen, press the key again. You should
now see a reaction. This occurs when a key is not pressed for a period of time sending
the sonde into a “sleep mode”. The f ir s t pr ess of any key “wakes” up the sonde and the
second press activates the command.
In order to properly assign sensors and parameters for the sonde, follow the step-by-step instructions below. You need not fully understand each submenu at this time, but you should configure your sonde menu to appear very similar to the screens shown below. The illustrations below may differ some from your screens, since sonde menus vary somewhat from model to model.
1. From Main menu press 3-System, then 1-Comm setup. This allows you to confirm baud rate at 9600, which is the default value. Refer to the screens below. Note also that the SDI-12 address of the sonde is 0 by default. You may assign any character between 0 and F to provide a specific address for your sonde. This will be of particular importance in multi-sonde applications involving the 6200 DAS. For now, maintain the “0” address designation. Press 0 to return to previous menus until you return to Main.

2.5 Configuring the 6200 DCP using EcoWatch DCP

All sensors connect to the 6200 DCP (Data Collection Platform). The DCP electronics physically reside inside the NEMA 4X enclosure. You should now have all of your sensors connected and a “direct link” RS-232 cable running from the 6200 DCP a COM port on your PC (COM1 in our example). You should have an antenna or RF cable connected to the antenna connector on the 6200 enclosure and you should have installed the battery and connected the power leads to positive and negative terminals. You are now ready to create a file, configure the data collection platform, and begin collecting data using EcoWatch DCP. Follow the step-by­step instructions below to proceed.
Start by opening EcoWatch DCP, if it is not already running.
From the main screen click on the top line menu labeled 6200, then click on New... to bring up the screen titled “Save 6200 DCP Configuration File As” Type in a filename of your choice (8 character maximum).
In the figure below the filename “checkout.s62” has been entered. Actually three configuration files (.s62, .zcf, .ini) will be opened and saved in the location shown (c:\ecowwin\sys6200). You have the option to direct the .s62 file to a location of your choice, but we recommend that you accept the default path. Click on OK to proceed.
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-11
YSI 6200 DAS USER Manual
Once you click on OK several status screens will appear indicating that EcoWatch DCP is attempting to detect the 6200 DCP and its sensors. The screens are part of an autoconfiguration routine that searches for SDI-12 sensors (sondes) and MET sensors (meteorological sensors). The screens are titled “6200 DCP ConfigWizard”. An example below shows that a sonde with SDI-12 Address 0 has been detected after scanning addresses 0 to 8. EcoWatch DCP searches from Addresses 0 to 9, by default. The sonde with the address of 0 will be the only address detected in your checkout procedure.
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-12
YSI 6200 DAS USER Manual
After completing the scan of SDI-12 sensors, the software switches to a ConfigWizard screen that shows the status of the scan of meteorological sensors. If a MET sensor requires entry of a calibration constant, a screen appears. Only the solar radiation sensor and barometer sensor require a calibration constant, which is provided in the sensor literature or included in the back of the manual. Each time you make a New 6200 file you will need to enter these calibration constants. A good place to save these calibration constants is with the manual. Below you see the MET status window and the screen for entering the calibration constants for the solar radiation sensor (pyranometer) and the barometer.
Enter the numbers from the certificates, then click on Next and proceed to the next screen in ConfigWizard.
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-13
YSI 6200 DAS USER Manual
The next choice relates to the communication option that you will be using for this particular file. For example, if you ordered a system with a 2-way radio, click on the appropriate circle. Remember that even though you may be “directly” communicating with the 6200 DCP field station during configuration, you must choose the mode of communication you will use for field
installation.
In our laboratory setup and checkout procedure we will be initially communicating directly via RS-232 cable. Therefore the default choice shown below is correct. Click on Next to proceed.
EcoWatch DCP now completes its configuration of the 6200 DCP. See the example screens below.
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-14
YSI 6200 DAS USER Manual
The last step EcoWatch DCP will do is to reboot the 6200 DCP, and you should hear a long beep. After you click on Finish, a report form similar to the one shown below appears on the screen.

2.6 Testing the 6200 DCP

At this point you have connected the 6200 DCP components, installed EcoWatch DCP and run the ConfigWizard. You are ready to begin collecting data and display it on EcoWatch DCP. In order to perform a test that provides data in a timely manner for testing, click on 6200, then 6200 DCP Setup. The following screen should appear.
Click on System… to open the window related to system settings. A message will appear to alert you that any data remaining in memory in the 6200 DCP will be erased if system settings are changed. This does not mean that data already uploaded to EcoWatch DCP will be lost. See Section 7 for more details on the consequences of changing system or sensor settings.
Click on Yes to continue and notice that there are two “folders”, Site/Timing and Communication/Power. Site/Timing will appear first and the Description box will be highlighted. By default, it reads <noname100>. The number 100 is the number EcoWatch DCP has assigned this field station, and may be any number between 100 and 999 since this value increments each time a new field station is setup. You may type in a description of your choice or you may tab to the next box, thereby accepting the default description. The next box is Sample Interval, that is the time that elapses between samples being logged to the data collection platform (DCP). The default value is 15 (minutes). Do not confuse this with
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-16
YSI 6200 DAS USER Manual
EcoWatch DCP interrogation timing. Even when EcoWatch DCP is not running, the DCP continues to log data to its memory once it has been configured.
The next selection gives you the choice of interrogating the DCP at the same rate as the sample interval or, alternatively, choosing some number of minutes independent of the DCP sample interval. For the 6200 Test, set the interrogation schedule to “Same as Sample Interval” by clicking on the box just to the left of this choice. Also change the Sample Interval to 2 or 3 minutes during the checkout routine in order to collect readings more quickly.
1
Now click on the Communication/Power folder and verify that communication is Direct Connect to PC and the COM port agrees with the serial port to which you are connected
(COM1 in our example screen). The power option should be Battery. The information related to MODEM communications is not relevant at this point.
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-17
YSI 6200 DAS USER Manual
Click on OK to exit the menu and return to the main EcoWatch DCP menu screen. A window appears momentarily, displaying the message Programming 6200...Please Wait. When EcoWatch DCP is done downloading the new configuration it will reboot the 6200 DCP. You should hear a long beep from the 6200 DCP as it starts up again.
Once the main menu appears, click on 6200 to pull down the menu and click on Interrogate Now. Any data that has been collected by the DCP will appear. If readings do not appear initially, you will need to wait as much time as the sample interval you chose above. A countdown timer in the lower right corner of the window will give you the time to next interrogation.
Below you see readings that have been uploaded to EcoWatch DCP from the 6200 DCP. Up to seven lines of data may be displayed at one time, the bottom line being the most current. Note that there are three separate display “sheets”. Simply click on the sheet label near the bottom of each window to view readings from YSI SDI-12 Sonde 0, MET Sensors, or Internal Sensors. You can not display all sensor readings in one window simultaneously.
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-18
YSI 6200 DAS USER Manual
If you have difficulty viewing the readings on a sheet, you have two options. One...click and hold on a vertical line that separates description headers. While holding the mouse button down you can resize the column width. Two...Click on 6200, Data Table Setup, Font/Color... The default font/size is Arial/11. Change this to suit your needs. For example, changing the size from 11 to 9 will fit more information on one screen without the need to scroll.

2.7 Testing Sensor Function

Now that you are able to view readings, you may wish to perform some preliminary tests of sensor function. As you have seen some readings display 0.000 in the checkout testing. For example, rain fall and accumulation, wind speed and direction and solar radiation probably have zero readings. Here are some quick tests you can perform.
For wind speed/direction locate the plastic arrow protruding from the MET Suite head assembly. Rotate the MET head assembly on the support so that the arrow points north (0 degrees). East would be 90, south 180 and west 270 degrees. Direction will not be displayed unless there is measurable wind speed. To check wind speed set up a small fan to provide continuous air motion in front of the propeller. During interrogation of the 6200 DCP, EcoWatch DCP will upload readings showing wind speed and direction. In the example below the wind speed is about 5.4 mph and the direction is 0
For rain rate/accumulation testing, remove the top assembly of the rain gauge to locate the tipping buckets. Carefully tip the buckets from one position to the other 5 to 10 times in
YSI/Massachusetts 508.748.0366, Fax 508.748.2543 Page 2-19
°
, which is due north.
YSI 6200 DAS USER Manual
succession. During the next sampling period, a rain fall between 0.05 and 0.10 inch should appear after interrogation. A rain rate, calculated based on accumulation per unit time also appears. For example, an accumulation of 0.06 inches in 15 minutes translates to a rate of 0.24 in/hour (4 15-minute intervals per hour, or 4 x 0.06).
For solar radiation remove the cap/dust cover and expose the sensor to natural light during the test period.
Other sensors should be producing values that indicate functionality. For example, the sonde temperature value should approximate room temperature. Relative humidity should be realistic for your room conditions. Barometric pressure should approximate a reading uncorrected for sea level. That means if you are not at sea level, altitude will cause a discrepancy between your reading and the local weather bureau’s reading. If possible, use a calibrated laboratory barometer to check for accuracy.

2.8 Displaying Data in EcoWatch DCP

After you have uploaded several sets of readings into EcoWatch DCP, close the 6200 file by choosing 6200, then Close.
Data files in EcoWatch DCP have a “.DAT” extension, unlike the 6200 DCP files which have “.S62” extension. There is one data file generated for each set of sensors (SDI-12 Sonde, MET and Internal). Each data file contains encrypted information related to time and identity of the file. Using the data file below as an example (1077BM00.DAT), note the following...
107 The field station number, assigned by EcoWatch, and incremented with each new field
station.
7 The last number of the year, for example, 1997 B The month of the year where 1=January, 2=February and so on to 9=September
A=October, B=November and C=December M Type of sensor where S=SDI-12 sonde, M=MET, I=Internal (eg, battery voltage) 0 SDI-12 Sonde Address, for example, Sonde Address 0 as shown above 0 Number indicating the set of data opened for a given record, 0=initial set.
If you change a report parameter or measurement unit for a file, the number increments
to 1, 2, 3… a, b, c… and so on.
Use the File command on the top level menu of EcoWatch DCP, then Open. Select the drive and subdirectory where the data files are located, usually c:\ecowwin\data. Highlight or click on the data file of the field station number and sensor type you wish to observe, then click OK. Below you see meteorological data for record 107 collected on November 18, 1997. Readings were collected every 2 minutes as part of a checkout procedure. Note the wind and rain events on the graph. By default, EcoWatch DCP opens the data file in graphical format with one parameter per graph. Autoscaling defines the upper and lower limits.
There are many options for displaying, reporting, and generally customizing the data in EcoWatch DCP. This is discussed in detail in Section 7. The objective of this section is for you to become generally familiar with this plotting/reporting software.
If you hold down the right mouse button you can scan through the data and show the actual readings correlating events with times. See the example below, which shows wind speed/direction events on the left side of the graph. We created these events in the 6200 DCP checkout procedure by spinning the propeller during the sensor reading period. Note that the wind speed/direction is zero for all other times.
To observe actual data records, click View, Data Table from the pull-down menus. After a while you will learn to use the icons and variety of other techniques for viewing, plotting and reporting data.
