5Chapter 1.IntroductionThis manual explains the hardware aspects of Adcon’s A724 Series 4 addSWITCH remote telemetry units, including installation issues and certain parameter configurations. The manual has the following chapters:•Introduction, which gives some general information and document conventions.•Using the addSWITCH, which details the installation and use of the remote telemetry unit.•Performing Advanced Functions, which discusses connectors and controllers and provides other information for advanced users.•Specifications, which describes operating parameters for the devices.AbouttheA724Series4addSWITCHThe A724 Series 4 addSWITCH™ remote telemetry unit (RTU) is a low-power, short-range telemetry device that can sample four pulse counter inputs and one analog input, and control two irrigation valves of the latching solenoid type.The frequency of operation is in the 432 to 470 MHz range, making it adaptable to most radio communication regulations in the world. The output power is 10 mW, while the modulation is narrow-band FM (12.5 or 25 kHz channel spacing).Due to its construction as well as to the software controlling it, the power consumption is extremely low. The unit operates off an internal
CHAPTER1Conventions66.2 Volt rechargeable battery, which is charged either by a solar panel or an external power adapter. A special configuration can be implemented where no internal battery is used, rather the power is obtained exclusively over an external connector.The A724 is a ruggedized unit, complying to the IP65 environmental protection class (NEMA 4). You can easily install and integrate the unit into an Adcon A733 network. Depending on the topography, you can get a reliable wireless connection to an A733 series device to distances up to 1000 meters. Under favorable conditions, the distance can be even farther.ConventionsCertain conventions apply in this document.Italics Indicate that the text is variable and must be substituted for something specific, as indicated in the explanation.

7Chapter 2.UsingtheaddSWITCHThe A724 Series 4 addSWITCH remote telemetry unit (RTU) is part of the A7xx series. For testing purposes, you should have an A840 or A850 Telemetry Gateway including the A440 Wireless Modem installed before you install the A724 Series 4 RTU. For information about installing the A840 or A850, refer to the device’s user’s guide.OpeningthepackagesThe addSWITCH RTU package contains the A724 Series 4 RTU, a valve connector cable, and a ring clamp. If ordered, the following items come in separate packaging:• A solar panel with ring clamp• A set of aluminum poles•An LED tool• Sensors and cables, one box per sensor, and one or several cable ties in each sensor boxMake sure you have received all the equipment and read through the instructions that follow. When you are sure you understand them, you are ready to install your RTU.
CHAPTER2InstallingtheRTU8Figure 1 shows the front view of an addSWITCH RTU.Figure 1. addSWITCH RTUNote: If you turn or manipulate the Gore Prevent element, the unit’s IP65 environmental protection could be affected.InstallingtheRTUThe following restrictions apply:• In general, the typical “line-of sight” distance the RTU can communicate is 1 km (0.6 miles). This is valid if both the RTU and its partner device are mounted on a 3 m mast (9 ft.). The results can vary under different conditions and you could achieve higher or lower distances.• As with all wireless communication devices, the higher the transmitter is installed, the better the communication will be.VALVECONNECTORANALOG ANDCOUNTERINPUTSTOSOLARPANELGORE PREVENTTM
CHAPTER2InstallingtheRTU9FieldInstallationIt is relatively easy to install RTUs in the field. You can perform a connectivity check with an LED tool, an example of which is shown in Figure 2.Figure 2. LED ToolNote: The LED tool is a blind plug to be connected to the POWER connector. Follow these steps to install Adcon’s RTU in the field:1. Review the installation area and choose the best site.2. Perform a connectivity check using the LED tool:a. Insert the LED tool into the POWER connector and wait up to 10 seconds. If the unit connects to at least one station (or a base station), it will light up the LED for about four seconds. b. Keep observing the LED tool and, after another several seconds, the LED will blink one or more times (the number of blinks indicates the number of stations it has contacted).3. Unpack the pole set. 4. Using a sledge hammer, drive the base pole (pointed tip) into the ground until it is securely and tightly seated. To prevent damage to the top of this pole make sure to put a protective cap on top of it prior to pounding it in. Such a pole pounder can be ordered from your Adcon distributor (item number 900.000.014).5. Using a ring clamp, fasten the solar panel onto the aluminum pole. Make sure that the panel is facing south (north if you are located in the southern hemisphere) and out of the way of the RTU.Note: The solar panel can be mounted under or behind the RTU, but be sure that the RTU does not shadow the panel.6. Fasten the RTU to the top of the pole using another ring clamp. Adcon recommends that you perform another connectivity test, if you can, to check the positioning of the device.  WARNING If you turn the fastening screws too tightly, you might damage the plugs.7. Attach the sensors to the INPUT connectors and the solar panel to the POWER connector by turning the plugs’ fastening screws clockwise until secure.8. Secure the extra length of the sensor cables to the pole with UV resistant cable ties.
CHAPTER2InstallingtheRTU10This completes the installation of your addSWITCH RTU. If one of the I/O connectors is left unused, use the cap provided to protect it against moisture and dust. Be sure to make a note of the following information because you’ll need it when you configure the device in the software:• Serial number of each RTU and location• Type of sensors connected to which port of each RTUMoreabouttheLEDtoolThe LED tool allows you to rapidly check the status of an RTU. After you insert the LED tool into the POWER connector, the unit waits up to two seconds and then sends a broadcast frame. If a nearby listening station or receiver decodes the frame, it will answer—this may take up to 10 seconds. When an answer is received, the LED tool lights up for about four seconds. After another few seconds, the LED lights up one or more times, depending on the number of stations/receivers that answered to its broadcast frame.In addition, the LED always blinks briefly at half-second intervals to indicate that the unit is alive and the internal battery has enough energy to operate. If the blinking interval lengthens to two seconds, the battery has become undercharged (that is, under 5.6 volts but over 5.2 volts)—this is called the misery state. In this state, an RTU reduces its activities to a minimum. The radio unit is switched off, the sensor sampling ceases, and no data is stored in the internal memory. Only the internal real-time clock is maintained and the power management functions are performed.If the battery level drops below 5.2 volts, the system switches completely off, effectively decoupling itself from the battery in order to protect it. In this case the LED tool stays permanently off. An RTU in such a situation will restart only after connecting it to an external power supply (even a solar panel under low light conditions).Note: New addSWITCH RTUs are delivered with their internal batteries unformatted, meaning they have never been charged before. You should install them only on sunny days. The battery will be fully charged after two consecutive sunny days, but you should get an LED light-up after several minutes of charging in the sunlight. You can also charge the unit with Adcon’s RTU charger (item number 200.733.550).TheaddTIMERextensionforaddVANTAGEPro5.3andnewerIn order to fully exploit the capabilities of the A724 addSWITCH, we have developed the addTIMER extension for addVANTAGE Pro. This extension lets you define several irrigation shifts by determining their start time and their run time in minutes. By assigning a valve to a predefined shift, addTIMER will automatically open and close each addSWITCH without further intervention by the user. This routine will continue until you modify or halt the sequence.
CHAPTER2MaintainingandservicingtheRTU11To configure the addSWITCH RTU in your A840 or A850 Telemetry Gateway and addVANTAGE Pro, please check the respective user guide.MaintainingandservicingtheRTUA Series 4 RTU needs virtually no maintenance. It is waterproof and designed to withstand harsh environmental conditions (-30 to +70 °C, or -22 to 158 °F), high RH values, water, and other non-corrosive liquids. It conforms to the European protection class IP65. This applies also to the connectors, as long as they are mated. Don’t let unmated connectors on either the RTU or the sensors be exposed to the environment for extended periods of time as this might seriously affect their functionality.TheRTUbatteryThe internal battery supplies 6.2 volts and consists of a NiMH pack. The internal electronics manage the battery’s charging/discharging process, ensuring it a long life time. This approach, coupled with a remarkably low average power consumption, allows an RTU to operate at least two weeks on a fully charged battery, under the following conditions:• The radio channel used has moderate radio activity, with requests every 15 minutes.• The analog and the counter values are stored in the internal memory every 15 minutes.• No more than 40 valve activations per day (12V Type).Table 1 shows the addSWITCH device’s expected operation time on a fully charged battery under various conditions.Note: “Radio activity” means that one base station and one to three RTUs are active on the same operating frequency and within the transmission distance of the addSWITCH.However, if for some reason (wearout or accident) the battery loses its capacity (noted in the software with repeated “Battery low” Table 1. addSWITCH Device Operation TimeRadio Activity Valve ActionsAverage Consumption (mA)Estimated Operation (days)No none 0.667 100Yes none 0.833 80Yes 40 1.8 37
CHAPTER2MaintainingandservicingtheRTU12messages), it must be replaced. Make sure though, that the problem is really due to the battery and not to a defective or dirty solar panel.Adcon highly recommends that you frequently check and clean your solar panels. Rain and dust can cover the solar panel’s surface with a thin layer of dirt, effectively reducing its power output. Surrounding vegetation can also lower panel efficiency.ReplacingthebatteryIf you have verified that the battery needs to be replaced, follow these steps to do so:1. Open the lid by unscrewing the four screws in the corners of the RTU, then remove the lid as shown in Figure 3. Make sure to use a 3mm Allen key to prevent damage to the screw heads.Figure 3. Removing the addSWITCH Lid2. The battery pack is connected to the electronics board by means of a PCB connector. Remove the battery pack’s plug from the PCB connector, as shown in Figure 4.
CHAPTER2MaintainingandservicingtheRTU13Figure 4. Unplugging the PCB Connector3. Unscrew the two nuts of the plastic cover that holds the battery pack in place, then remove the cover. Figure 5 shows the battery pack inside the RTU. Figure 5. Battery Pack4. Remove the battery pack and replace it with a new one (obtainable from Adcon).5. Replace the plastic cover and fasten the two nuts.6. Insert the battery plug into the PCB connector. WARNING Be sure to mount the rubber gasket properly, so that the unit’s IP65 environmental protection is not affected. You must also be sure to not squeeze the battery cable.7. Mount the lid back, taking care that the rubber gasket sealing the box is correctly in place and free of dirt and soil.

15Chapter 3.PerformingAdvancedFunctionsWith the appropriate knowledge, you can configure addSWITCH devices in the field by using a hyperterminal window. To configure the RTU, you will need a special serial cable adapter (not supplied, but available from your Adcon distributor). CAUTION Do not try to configure your RTUs if you are not sure what to do—the unit might not communicate with the remote measuring station or function with the addVANTAGE software. WARNING Tampering with parameters for the RTUs may void your warranty or damage the device. In general, the commands described in this chapter are intended for technical support staff and users with a great deal of highly technical hardware and software experience.In the system architecture, the base station and RTU are both considered to be nodes. The base station is called the master node, or master, while the RTU is called the slave node, or slave. UnderstandingconnectorsThe addSWITCH devices have cable attachments called connectors. The connector type determines how the device communicates with the sensors or the computer.TheRTUconnectorThe A724 Series 4 addSWITCH RTU uses a non-standard 7-pin sensor I/O connector (model Binder 702 and 712 series or equivalent). The
CHAPTER3Understandingconnectors16connector contains four pulse counter inputs, one analog input, and a sensor supply voltage output. Figure 6 illustrates the individual pins of an I/O connector.Figure 6. Pins on the I/O Connector (Top View)ThePOWERConnectorThe RTU also has a POWER connector, which allows for:• External supply (battery or any DC source from 5.6 to 10 volts)• External charge supply (either a solar panel or an AC adapter) if an internal rechargeable battery is used• Communication over serial lines, at 19200 baudFigure 7 illustrates the connections available at the POWER connector.Figure 7. A724 POWER Connector (Top View) WARNING The serial line is 3-volt CMOS compatible; therefore, a special adapter cable must be used to reach the RS-232 levels. Also, if an external battery is used, the internal battery must be disconnected.You might want to use the POWER connector with something other than the standard configuration. For example, if you want to connect an external battery to the RTU, disconnect the internal battery and use the configuration shown in Figure 8.SBATCNT3 CNT0CNT1AN0GNDCNT27365124ExtPowerTxDRxDGroundBattery52413

The Valve Connector WARNING Do not use only one COM wire for all valves.Connect the positive terminals (commonly red) of the valve to the corresponding Valve1-4 pins and the negative terminals (commonly black) to the COM pins. WARNING Be sure to check the cabling, otherwise one or more valves will switch to ON state when the RTU enters misery mode or upon a reset of the RTU.Note: COM wires brown and green should be used for valve1 and valve2, pink and blue for valve3 and valve4.The cable colors of your valve may differ from this scheme. Please consult the manufacturer of your valves.Note: When the polarity is reversed, the valve operation is also reversed. The user can check the correct cabling with the power up sequence of the A724. WARNING Be sure to check the cabling for shortcuts because the RTU can be damaged when it is operated with improper connections.When the A724 starts up (e.g. the battery is connected), it immediately sends OFF commands to all valves (sequential).Valve1COMValve3Valve2Valve4COM146253Table 2.

CHAPTER3CommunicatingwiththeRTU19CommunicatingwiththeRTUYou can use a Windows Hyperterminal window to connect to the addSWITCH RTU. After you have installed the system, follow these steps to configure the device and set the default parameters:Note: To configure the A724 Series 4 RTU, you must have a special adapter cable (item number 200.720.540 from your Adcon distributor) and plug it into the POWER connector.1. Open a Hyperterminal window.2. Select the appropriate serial port and click OK.3. Configure your terminal as follows: • 19200 baud •1 stop bit• 8 data bits•No parity• No protocol (neither hardware nor software) 4. Select OK to open the terminal window.5. Press Enter to generate a response in the window.Note: Beginning with the A724 Series 4, RTUs operate in two modes, bootloader and firmware.BootingtheRTUNote: This section is included for informational purposes. You will rarely need to boot the RTU. However, when you do need to do so, you will work within a Windows Hyperterminal window on your computer.When the Series 4 RTU starts from a power-up reset (such as when you connect the battery to the RTU), it enters the bootloader mode. If you press no keys in the interim, the RTU enters the firmware mode in five seconds. If you want to work with commands in the bootloader rather than continuing to the firmware mode, press ESC within five seconds after seeing the following sign-on message:A724_S4 Bootloader V1.7Copyright (C) Adcon Telemetry GmbH 2009Press <ESC> within 5 seconds to start the commandline interface...You are in the command line interface. The command line interface enables you to perform certain commands such as rebooting the RTU and upgrading to a new firmware.Note: If you press no keys within 60 seconds, the command line interface will start firmware mode automatically.
CHAPTER3UpgradingtheFirmware20In bootloader mode, the command line interface’s prompt is the character >. Therefore, to reboot the RTU just type the following after you see the > prompt: rebootAn alternative way to boot the RTU is to disconnect the battery and after a few seconds reconnect it.For a list of the available commands, type Help at the > prompt.Available commands:upgrade [baudrate] ... upgrade from Y-modem downloadversion ... show the version of the bootloaderstate ... show the board statereboot [id] ... reboot the RTUfirmware ... start the firmwarehelp ... display this help textNote: For some commands, such as the reboot command, you can supply the ID of the RTU. FirmwareModeWhen you enter firmware mode, the following message is displayed in the Hyperterminal window:Checking firmware ... firmware found!41239 0#The bootloader scans the program memory for a valid firmware by testing the checksum, which takes a moment. If everything is correct, the "firmware found!" message appears.A moment after the firmware is found, the RTU’s identification number (for example, 41239) and error code (in this example, 0) are displayed. After another moment, the firmware mode’s command line interface prompt is displayed (#). If you need to return to bootloader mode when you’re in firmware mode, enter the Reboot <ID> command at the prompt.See “Using terminal commands” on page 24 for commands available in firmware mode.UpgradingtheFirmwareNote: This section is included for informational purposes. You will rarely need to upgrade the firmware. However, when you do need to do so,
CHAPTER3UpgradingtheFirmware21you will work within a Windows HyperTerminal window on your computer.Before upgrading the firmware, you must reboot the RTU to access the bootloader mode’s command line interface. Follow the procedure described under Booting the RTU to get into the bootloader.Before you start the upgrade, it is very important that you copy the firmware image to the hard drive of the computer you use in the field.You also need to know which version of the bootloader you are running. You can determine the version any of the following ways:• Look at the bootloader’s signon message when you start it.• At the bootloader mode’s > prompt, enter the Version command. • In firmware mode, enter the Reboot <ID> command and look at the signon message.• In firmware mode, enter ver at the # prompt.Now you’re ready for the upgrade.1. At the ’>’ prompt, enter the following command:upgrade 115200The upgrade process starts. Note: For pre-1.7 versions of the bootloader, omit the speed parameter (115200 used to be the default). For 1.7 and later versions, include the 115200 baudrate parameter. If you do not specify a baudrate, the upload runs at the default 19200 baudrate.Change the baudrate of your terminal to '115200' and hit <Return> to start flashing.2. Select FileProperties to open the hyperterminal’s Properties dialog.3. Select a com port for the Connectusing field.Note: If your bootloader is version 1.7 or later and you used the > update command rather than the > update 115200 command, you can skip Step 4 through Step 6. The bootloader will use a baud rate of 19200.4. Click the Configure button to display the com port’s Properties dialog (Figure 12 shows a COM1 com port).

From the hyperterminal window’s menu bar, select TransferSendFile to display the dialog shown in Figure 13.Note: You must start the image upload within 60 seconds or a timeout will occur.Figure 13. Dialog to Upload Firmware Image11. Browse to and select the firmware image.12. Select the Ymodem Protocol and click Send.13. To start the new firmware, enter the following command:firmwareSerialcommunicationprotocolThis protocol is based on a master sending commands and a node answering. The whole communication is conducted in plain ASCII, as strings, and numbers are represented in decimal format. All commands are terminated with a CR/LF combination. All responses (answers) are terminated with the # character.GeneralformatofacommandThe commands have the following format:ID Command Param1 Param2 ... ParamN•ID is the destination device. If you include an ID as part of a command, the node checks whether ID=ownID. If it does, the node executes the command on itself. If the ID is not the node’s ID, the node executes the command on a remote device, if such an ID exists. If the ID is missing, this implies that the command is addressed locally.Note: Not all the commands can be relayed remotely.•Command is the command proper, which can be composed of a variable string of characters (for example, SLOT). Each node can implement a set of commands depending on the functionality of the node itself. However, as a minimum requirement, a node recognizes the CMDS command, which returns a list with the commands accepted by the node.
CHAPTER3Usingterminalcommands24•Param1 Param2 ... ParamN represent the parameters, which are command dependent. If you type no parameters when you issue a command, it is the equivalent of querying for information (the GET version of a command). If you type parameters, you are issuing the SET version of a command and are setting the command to the parameters you typed.GeneralformatofananswerThe answers have the following format:ID Command Result1 Result2 ... ResultN ErrResult #•ID is the answering device. If a command was further routed, it is the ID of the end device. The answer must always contain the ID on return.•Command is the string representing the original command. It is supplied so that a master can distinguish between the answers it is waiting for, and out-of-band notifications (which may come, for example, over the radio port of a node). As with the ID, the command name must always be supplied.•Result1 Result2 ... ResultN are the result values returned by the remote node. If the ErrResult is not zero, all other possible characters and/or strings until the end of the line might be ignored.•ErrResult shows whether the command was successfully executed. If this value is 0, the command was successfully executed. If this value is other than 0, the command failed. The number may further indicate the error type. (See also “Returned errors list” on page 42.)The answer string may contain any number of spaces or CR/LF characters between its components. However, after the terminator (#), no other characters are allowed.UsingterminalcommandsThe addSWITCH A724 firmware is basically the same as the addIT A723 Series 4, except for the following items:• new device type: A724_S4• digital ports are used internally for valve control (bit 4-7)Following is a list of available commands and an explanation of their use.

The second parameter is the timeout in seconds (1-65536). When the timeout occurs without a port change on a configured port, a digital port event will be enforced. This is useful for having regular port state updates and additionally updates when the port state changes. Use 0 for the second parameter to turn off the timeout.Note: A low timeout value will produce a lot of dataframes, which might overload the radio channel transmission capacity!

The dynamic slot switching function checks whether the measurement value of a given sensor matches the given condition, then switches between two operating modes:1—normal mode (when the condition is false and the lock timer is zero)2—execution mode (when the condition is true and the lock timer is non-zero)The rules for the mode switching are:• When the condition becomes true the first time, exception mode is entered and the lock timer is set.• While the condition is true, the lock timer is set at every sample; thus it does not reach zero.• While the condition is false, the lock timer is decremented if not already zero.• When the lock timer reaches zero, normal mode is entered.• The SLOT settings are changed only when the mode changes.Thus, the RTU enters exception mode whenever a sample value matches the condition, and stays there until the sample value does not match the condition for at least the given lock time (this prevents excessive wear of the EEPROM due to jitter in the measurement value).PARAMETERS 1—sensor type (0=none, 1=internal battery, 2=anlg, 3=port, 4=counter).2—sensor address (channel number as in the ANLG and PORT command).3—limit type (0=above, 1=below, 2=out of range, 3=within range).
