SENTRICON* SYSTEM INSTRUCTION MANUAL *Trademark of Dow AgroSciences LLC TABLE OF CONTENTS I. QUICK START INSTRUCTIONS II. SYSTEM DESCRIPTION III. SPECIFICATIONS FCC STATEMENT The interrogator generates low-level radio frequency energy. The unit has been tested and found to comply with the limits and specifications as set forth in Part 15 of the FCC rules. If this unit is suspected of interfering with radio or television reception, verify that the unit is indeed the source of the interference. First, remove power form the devices. If the interference continues, then the unit is not the source of the interference. If the interference stops upon power-down of the unit, then reapply power to the interrogator. If the interference begins again, proceed as follows: • Reorient the receiving antenna on the unit experiencing interference. • Move the interrogator farther from the unit experiencing interference. • Change the orientation of the interrogator antenna. If necessary, contact the manufacturer for additional suggestions. Any changes or modifications not expressly approved by Donnelly Electronics Inc. may void the users authority to operate the equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. QUICK START INSTRUCTIONS Immediately upon unpacking the interrogator, verify that you have received the following items: BATTERY CHARGER For units to be used in the US and Canada, this unit is Elpac model WP1224. The input voltage is 100 to 120 volt 47-63hz. If your electrical service differs from these specifications, do not attempt to charge the batteries and contact the supplier of this interrogator immediately for an exchange. INTERROGATOR HANDLE This unit consists of two pieces: The armrest, and bottom leg. ANTENNA This unit is a white circular disk, eleven inches in diameter. It will be connected to the bottom leg of the interrogator handle. INTERROGATOR ELECTRONICS BOX This unit is a rectangular box attached to the armrest section of the interrogator handle. Depress the POWER switch on the rear panel of the INTERROGATOR ELECTRONICS BOX. The unit should emit a single ‘beep’ and the green POWER LED should be illuminated steadily. If the LED is flashing, you should immediately charge the batteries. To charge the batteries, plug the power supply that was shipped with the interrogator into a 120 vac wall outlet. Insert the plug from the charger into the jack on the rear panel of the INTERROGATOR ELECTRONICS BOX. This jack is labeled ‘CHARGER’. The yellow LED labeled ‘CHARGE’ on the front panel will now be illuminated. If the batteries are severely discharged, the Yellow LED may blink for several hours while the charging circuitry is conditioning the batteries. Once the conditioning has terminated, the Yellow LED will emit a steady glow. When the charging cycle has been completed, the LED will extinguish. To verify interrogator operation as a stand-alone unit, it is not necessary to have the transceiver in operation. No meaningful data will be obtained from this operation, but it is instructive to test out the operation of the transensors and interrogator. The following paragraphs will explain how to operate the interrogator: Depress the ‘POWER’ switch located on the rear of the electronics box to enable interrogator operation. You will hear a single “beep” tone from the interrogator when the switch is depressed and the self –test operation has been successfully completed. The GREEN LED labeled ‘POWER’ will illuminate. The interrogator is now operating normally, and is continually scanning for a transensor. Since the interrogator is only a portion of a system, it is necessary to have all the other parts of the system operational in order to get meaningful data from the interrogator. One can test the interrogator’s operation without the other components of the system by placing a transensor near to the antenna. When the interrogator powers up the transensor, the identification code of the transensor is sent to the interrogator, and BOTH the ‘ACTIVE’ and ‘INACTIVE’ LEDs will turn on. The interrogator will emit a single “beep” to indicate that the transensor has been read. Both LED’s will remain on for about 2 seconds and then go off. This operation is the same regardless of whether a sensor is connected to the transensor or not. After approximately two 1/2 minutes of inactivity, the interrogator will automatically shut down to conserve battery power. Although the above operation does not do anything useful and is not very spectacular, it does give a feel of the operation of the interrogator. The interrogator will operate for about 8 hours on a full battery charge, but it is good practice to charge the batteries at least at the end of each day. As a minimum, the interrogator should be charged on a weekly basis since some of the internal circuitry continuously draws battery power and will ultimately completely discharge the batteries. This will result in diminished lifetime of the battery pack. The battery chemistry is NiMH and thus will not exhibit the notorious “memory effect” common to NiCd batteries. Therefore, it is not necessary or desirable to wait for the batteries to discharge before recharging them. To complete the system, the Dolphin 7200 must be inserted into the Dolphin cradle slot. To insert the Dolphin into the cradle slot, grasp the top end of the Dolphin with the IR port pointing into the cradle push the unit into the cradle. Ensure that the Dolphin is fully inserted. Turn on the Dolphin 7200 and the PROLINX software will start automatically. Operation of the PROLINX software is beyond the scope of these instructions; however, proper starting of the software will allow for the Sentricon System to begin working. Now, depress the Power switch on the rear of…

Dolphin Interrogator The Dolphin Sentricon System consists of a transponder, sensor, interrogator and a Hand Held Dolphin. The following sentences will give a brief description of each of these units. The system is used to detect termites The sensor is an electronic device that is sandwiched between the wooden monitoring devices of the Sentricon unit. The sensor is a passive device that can be consumed by termites. When this event occurs, the electronic state of the sensor is altered. This change of state of the sensor is the event that indicates the presence of termites within the Sentricon unit. The Transponder is a device that contains all the electronics necessary to derive its power from the interrogator, detect the state of the sensor, and provide a unique identification code to allow PROLINX software to determine specific information about the Sentricon station. The Interrogator housing contains visual displays and an audio alarm to give the user feedback regarding the status of the interrogator as well as the status of a Sentricon transponder. The 4 LED’s list as followed a green LED on the left of the display window indicates POWER ; Sensor status displays are placed in the center of the display. The two LED’s are labeled ACTIVE and INACTIVE. The ACTIVE LED is colored red when termites are present and the INACTIVE LED is colored green when no termites are present. On the right side of the display is the CHARGE LED, which is colored yellow when plugged into a wall outlet. The Dolphin cradle on top of the black box is for IR data communication between the Dolphin and the Interrogator. The Dolphin 7200 receives data from the Interrogator stores the data and confirms the data is correct and sends an ok signal back to the interrogator, to notify the operator of the status of the transponder.
