Safety Information
Chapter 2 Overview The In-Situ Aquaculture System provides large or small fish farming operations with a reliable and easy-to-maintain water quality monitoring system.
FIGURE 1. Main components of the buoy Transceiver Solar panel Battery box DO sensor, cleaning brush, and cleanser dispenser 2.3 DEPLOYMENT CONSIDERATIONS • Ensure that the DO sensor and brush are adequately submerged in the pond (at least 2 feet deep), sufficiently away from the pond’s edge or above the bottom of the pond. • Do not carry the buoy by the conduit. Carry it by the float. Otherwise you may damage the wiring. • Anchor the buoy.
Chapter 3 3.1 Sensors RDO® PRO DISSOLVED OXYGEN (DO) SENSOR The RDO PRO DO sensor ships pre-installed on the buoy. The sensor is rugged, reliable, and designed to deliver accurate DO and temperature data across a wide measuring range while reducing maintenance costs. It features the latest optical technology for DO measurement. The main components of the sensor include: • • • • Black sensor body Removable nose cone Optical DO sensing cap Thermistor (for measuring temperature) FIGURE 2.
FIGURE 3. Removing the RDO sensor from the buoy to attach the cap Note: Avoid allowing moisture, including atmospheric humidity, inside the cap. Keep the cap in its sealed packaging until you are ready to install it. Install promptly. Make sure that O-ring grooves are dry and the Oring is not rolled or pinched inside the cap. 10 5. Unscrew the nose cone from the sensor and remove the red protective dust cap from the sensor. Save the dust cap for use during storage, if applicable. 6.
FIGURE 4. Placing the cap on the sensor and replacing the nose cone Note: The cap's lifetime is 1 year after the first reading has been taken. Install by the date printed on the packaging. 3.1.2 8. Reattach the nose cone. 9. Reattach the RDO sensor and white PVC fitting. Do not completely tighten the white fitting. You will need to adjust the sensor so that it touches the brush in the next section. Adjusting the Wiper Brush 1.

Chapter 4 4.1 Buoy Transceiver OVERVIEW The transceiver consists of: • A microprocessor that is programmed to take sensor readings at given intervals • A radio module that transmits the sensor readings to the host PC • A desiccant pack (PN 0063100) In between the readings, the radio module operates in sleep mode, enabling the buoy to operate with lower power consumption. 4.2 ADDRESSING Each transceiver has a different address that identifies the buoy when communicating with the host PC.

4.4 RADIO DESCRIPTION The buoy system uses a 900 MHz spread-spectrum radio manufactured by Digi® International Inc. The configuration of these radios is site-specific and usually involves setting the following parameters: • • • • • Hopping Channel Destination Address Address Mask Module VID Sleep Mode Refer to the Radio Replacement Instruction Sheet at www.in-situ.com for information on how to modify these parameters. 4.
Chapter 5 5.1 Host PC OVERVIEW The host computer can be any Microsoft® Widows®-based PC operating with a Windows® 98 or later operating system. Additional PC requirements include: • At least one serial communications port, or the serial adapter available from In-Situ. • A radio modem connected to the serial port in order to communicate with the buoys and wireless controllers. (DigiKey® 9X Stream RS232 9.6 kbps, part number (1P) X09-009PKC-RA is recommended and is available from In-Situ Inc.
FIGURE 11. PC connections to host radio Antenna Serial cable to radio PC Power Cable Radio Power Cable 5.3 FARM STATUS SCREEN—OVERVIEW OF TOTAL FARM STATUS The Farm Status screen can quickly reveal problems with ponds and monitoring equipment. This real-time screen is updated every minute and displays a pond icon for each pond of the farm. FIGURE 12.
5.3.1 Pond Color—Oxygen Concentration Spectrum The background color of each pond icon represents the oxygen level of the pond. The color varies from bright yellow, indicating a high oxygen concentration, to deep brownish red, indicating low oxygen concentration. 5.3.2 Pond Border Color—Aerator Status The status of aerators is indicated by the border color of the pond icon. • Aerator 1 Running - Pink • Aerator 2 Running - Green • Aerator 1 and 2 Running - Blue The colors show which aerators are running.
5.4 GRAPHICS VIEW 1. Click on a pond icon, and select Graphics and Aerator Report from the menu that appears. A chart of oxygen readings and the aerator run-time graph for the same period will be created. This is useful for comparing oxygen levels with aerator run times. If the graph shows low oxygen for a time period and no aerator run time, the aerator should be inspected.
FIGURE 14.
5.6 POND STATUS SCREEN—QUICK VIEW OF LAST 24 HOURS The menu on the top of the Pond Status Screen offers the following choices: Calibrate, Set Aerators, Set Phone Alerts, Status, and Setup. FIGURE 15. Example of pond status screen 5.6.1 Calibrate 1. On the main menu of the Pond Status screen, select Calibrate. 2. Select the pond to be calibrated. 3. Use the up and down spinners at the right to increase or decrease the oxygen reading until the desired level is set. 4.
5.6.2 Set Aerators The Set Aerators window controls the set points for turning the aerators on and off. 1. On the Main menu of the Pond Status screen, select Set Aerators. 2. Select the pond that needs the aerators set. FIGURE 17. Setting the aerator on/off limits 3. There are two aerators indicated, Inside and Outside. Click one of these options. 4. The current On and Off limits will appear in the text boxes at the right. Use the spinners to change the levels and click OK to save them. 5.
5.7 CONFIGURATION FILE The system configuration file is a text file named CatHostDir.txt. It is located in the application folder and appears as the following: \Data Start-up Period(Hours),.25 Maximum Interval Between Communications(Minutes),20 Minimum Time Between Alerts(Minutes), 2 Early Off Start Time,7 Early Off End Time,16 Early Off Diferential,.
FIGURE 18. Phone alert limits The system will call any number set up in the MyPhoneNumbers.txt file in the applications folder. If a number is not answered, the next number in the list of numbers is called. The system continues to cycle through the list of numbers until someone answers. When the call is answered, a voice message indicates the type of problem. The answerer must press a digit on the phone to signal to the computer that the message was received. Otherwise, the computer will continue to call.

Chapter 6 6.1 Care and Storage CLEANING THE OUTSIDE OF THE ENCLOSURE Wipe the enclosure as needed with a damp cloth. Do not use solvents. 6.2 STORAGE RECOMMENDATIONS • If you remove the buoy from service seasonally, remove the battery from the buoy and store separately. • If the sensor cap will expire before you redeploy the unit, discard the cap and place a red dust cap over the end of the sensor. If you do not have a dust cap, just keep the sensor cap on.
conditions. Replace as necessary. These tablets are available anywhere swimming pool supplies are sold. 6.3.4 Cleaning the Sensor Cap Note: Do not use organic solvents—they will damage the sensor cap Do not remove the cap from the sensor prior to brushing. 6.3.5 If extensive fouling of the sensor occurs, remove the buoy from the pond and complete the following steps: 1. Leave the cap and nose cone on the sensor! 2. Rinse the sensor with clean water from a squirt bottle or spray bottle. 3.

Chapter 7 7.1 Troubleshooting TROUBLESHOOTING THE BUOY The buoy operates in extremely harsh environments. If you suspect that something has malfunctioned in the buoy, pull the buoy from the pond and visually inspect the following: • The probe and brush—Make sure that there is no biofouling, feed, or mud interfering with the operation of these parts. • The brush motor—Make sure that the brush did not become tangled in algae or other material and burn out the motor. • The chlorine tablet—Replace as needed.
