8071 Programmer Plus and 8081 Radio Programmer Plus Operating Instructions Application and Features The Nelson 8071 Programmer Plus and 8081 Radio Programmer Plus consoles are used to program 8030 Series Remote Programmable Actuators or 8050 Series PG Multi-Station Actuators. The programming is accomplished through a secured, waterproof, telephone plug. A cord is provided with the Programmer to attach to the actuator. The Programmer can program up to 16 watering schedules per day with watering times from 1 minute to 24 hours in one-minute increments. Each independent schedule has a start time, a finish time, a 14-day watering calendar and valve assignment (PG Multi-Station Actuators only). There is also a timed manual operation from 1 to 99 minutes. The Programmer Plus console can program an interruption of starts (rain mode), which interrupts all watering schedules without disturbing the original program. Additional 8081 Radio Programmer Plus Features The 8081 Radio Programmer Plus console communicates via radio link with 8050 Series PG Multi-Station Actuators equipped with a model 8060 Radio Adapter. With the radio link, all programming features may be utilized. The Programmer must be within 6 feet (2 meters) of the actuator unit, if the actuator is in a standard plastic valve box. If the actuator is above ground and in line of sight to the Programmer, the units must be within 60 feet (1 8 meters) for proper operation. Operation To turn the Programmer on, press "+". To turn the programmer off, return to the opening screen and press "-". The Programmer will automatically turn off after five minutes of inactivity. Programming is accomplished by following the directions on the screen and using these four buttons: >Advance to the next screen or advance the cursor to the next value <Go back to previous screen or make the cursor go back to the previous value +Increase the value (or turns value on) of the number in the blinking cursor Decrease the value (or turns value off) of the number in the blinking cursor Most operations are selected by choosing an option on the Programmer display. The following are for your further reference. Disconnected Menus The following menus are available when the Programmer is not connected to an actuator. Setting Time and Day (TIME) - The current time and day can be set for the Programmer. The Programmer will ask if you want a 12 hour (AM/PM) or 24 hour clock. When the Programmer is connected to an actuator, the programmer automatically updates the actuator time and day. Choose Language (LANGUAGE) - Select your choice of English, French, Spanish, Italian or Portuguese. Set Programmer Code (PROGRAMMER CODE) - Each programmer has a four digit code. This code is important if you are communicating via radio link with the 8081 Radio Programmer Plus. The actuator will only communicate via radio with one specific code number 8081 Programmer. Establishing Radio Connection (RADIO CONNECT) - See later section: "Radio Connection 8081 Only". Advanced Menus (ADVANCED) - See later section: "Advanced Menus". Connected With a Cord to 8030 Series Remote Programmable Actuator or 8050 Series PG Multi-Station Actuator Menus Once the telephone cord is plugged into the 8030 Series Remote Programmable Actuator or 8050 Series PG Multi-Station Actuator, a new series of menus is accessible. Programming Actuator (PROGRAM ACTUATOR) - You may set a start time, a finish time, a 14day watering calendar and valve assignment (PG Multi-Station Actuators only) for 16 independent watering schedules. Use the four buftons to move the cursor and change the values in the blinking cursor. You may clear any program by simultaneously holding down "<" and "-" while the cursor is blinking in the PROGRAM No: ## position. Manual Operation (MANUAL) - You may run a timed manual operation at any time by selecting START. Before executing the timed manual operation, the actuator will delay 30 seconds after the Programmer is disconnected before beginning watering. If you leave zero minutes for RUN TIME, the actuator will open immediately and close when disconnected (will open and close immediately when communicating via radio). Choosing STOP will close a valve that is running. If the valve was running a normal watering schedule, the valve will open again and finish its schedule when the programmer is disconnected. Rain Mode (RAIN) - Prevents the actuator from watering when you select RAIN. The program will still be retained, but no watering will occur. To resume watering, you need to use the same menus and select the normal SUNNY mode. The initial status screen will indicate if the actuator is in the RAIN or SUNNY mode. Choosing the Actuator ID Code (ACTUATOR ID) - This is a three digit code that identifies the actuator. You must know the actuator ID code to connect via radio (see next section). In addition, the code number of the Programmer that sets the actuator ID is the only Programmer code that may communicate via radio with that actuator. Advanced Menus (ADVANCED) - See later section: "Advanced Menus". Radio Connection Menus - 8081 Radio Programmer Plus Only The actuator must be attached to a radio adapter. To establish a radio connection the Programmer must be within 6 feet (2 meters) of the actuator unit, if the actuator is in a standard plastic valve box. If the actuator is above ground and in line of sight to the Programmer, the units must be within 60 feet (18 meters) for proper operation. Establish Radio Connection (RADIO CONNECT) - You must enter the three digit actuator code. The Programmer will take a few seconds to establish a radio link. The programmer will display RADIO CONNECTION to confirm the link. If you cannot establish a link, refer to the following troubleshooting chart: CauseSolution low battery in actuatorchange actuator battery incorrect actuator or programmer codeconnect with cord and set a new actuator code with Programmer Plus Radio too far away from actuatormove to within 10 feet (3…

L.R.Nelson Corporation Jul-98 Description of the Transmitter and Receiver used in L.R.Nelson Solorain Product Line The receiver and transmitter units are housed on a single printed circuit board to make up a digital transceiver. The 8060, 8040 and 8081 use the same receiver and transmitter chip sets. The 8060 and 8040 also incorporate an 8-bit microcontroller to encode and decode data to and from another transceiver pair. The 8060 and 8040 transceivers will reside on small, battery powered water valve controllers used for commercial and consumer irrigation systems. The transceivers will enable wireless programming of the intelligent water valves using a battery powered console incorporating an 8081 transceiver radio. In most applications, the intelligent water valves will be housed underground within irrigation valve enclosures. The handheld consoles will be used by irrigation contractors to program the intelligent valves as needed. Both the console and intelligent water valve incorporate microcontroller technology. Present communication between the two devices is accomplished using a three-wire serial connection. Wireless transmission will modulate the digital serial data using an OOK (On-Off Keying) technique. A mark symbol is represented in the presence of a sine wave carrier and a space symbol is the absence of that carrier. The console and intelligent water valve will operate the transceiver units in the same manner as the three-wire connection.

EMC TEST SERVICES REPORT NO. 6771 Kind of Equipment: Commercial and Consumer Irrigation Systems S/N: NA 1.0 SUMMARY OF TEST REPORT It was found that the Nelson 8081 Programmer Plus Consoles, S/N NA "meets"the radio interference emission requirements of the FCC "Rules and Regulations", Part 15, Subpart C, Sections 15.249, 15.207 & 15.209, for Intentional Radiators used in the frequency bands 902 to 928 MHz. It should be noted that the amount of margin was only 2.68 dB at 1833.22 MHz, radiated. The normal tolerance of the test equipment is + or - 3 dB. Due to this tolerance and the variation in normal production, a margin of at least 4 dB is recommended. With only a 2.68 dB margin, there is a probability that if this or another unit were tested by the Domestic or Foreign Compliance Regulatory Agency using similar equipment, it could be found to not meet the above requirement. 2.0 INTRODUCTION On July 20 & 21, 1998, a series of radio frequency interference measurements were performed on Commercial and Consumer Irrigation Systems, S/N NA. The tests were performed according to the procedures of the FCC as stated in the "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz" found in the American National Standards Institute, ANSI C63.4-1992 (Revision of ANSI C63.4-1988). Tests were performed by personnel of D.L.S. Electronic Systems, Inc. who are responsible to Donald L. Sweeney, Senior EMC Engineer. 3.0 OBJECT The purpose of this series of tests was to determine if the test sample could meet the radio frequency emission requirements of the FCC "Rules and Regulations", Part 15, Subpart C, Sections 15.33, 15.207, 15.209, & 15.249 (a-d), for Intentional Radiators used in the frequency bands 902 to 928 MHz. Page 8 D.L.S. ELECTRONIC SYSTEMS, INC. EMC TEST SERVICES REPORT NO. 6771 4.0 TEST SET-UP All conducted emission tests were performed in a shield enclosure or lab at D.L.S. Electronic Systems, Inc. The conducted tests were performed with the test item placed on a wooden table located in the Test Room. The power line supplied was connected to a dual line impedance stabilization network located on the floor, a ground plane. The networks were constructed per the requirements of the American National Standards Institute, ANSI C63.4-1992, Section 4, (Figure 2). The only ground supplied to the unit was through the third wire of the standard power cord when supplied. 5.0 TEST EQUIPMENT (Bandwidths and Detector Function) All preliminary data below 1000 MHz was automatically plotted using the HP 8566B Spectrum Analyzer. This data was taken using the Peak or CISPR Detector Functions. This information was then used to determine the frequencies of maximum emissions. Above 1000 MHz final data was taken using the Peak Detector. Below 1000 MHz final data was taken using the EMC-25 fixed tuned receiver. Plots were made using the Peak Detector, with manual measurements made on the frequencies of interest, using the Peak and CISPR Detector Functions of the receiver. The actual detector used is indicated on the spreadsheets found in the Data Summary Section of this report. The bandwidths used are specified by the FCC as stated in the American National Standards Institute, ANSI C63.4-1992, Section 4.2. From 30 MHz to 1000 MHz a bandwidth of 120 kHz was used, and above 1000 MHz, a bandwidth of 1 MHz was used. A list of the equipment …
