Introduction This manual explains the hardware aspects of Adconâs 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 addSWITCH The 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 1 Conventions 6.2 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.

Using the addSWITCH The 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 deviceâs userâs guide. Opening the packages The 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 box Make 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 2 Installing the RTU Figure 1 shows the front view of an addSWITCH RTU. GORE PREVENTTM VALVE CONNECTOR ANALOG ANDCOUNTER INPUTS TO SOLAR PANEL Figure 1. addSWITCH RTU Note: If you turn or manipulate the Gore Prevent element, the unitâs IP65 environmental protection could be affected. Installing the RTU The following restrictions apply: ⢠⢠In general, the typical âline-of sightâ 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. CHAPTER 2 Installing the RTU Field Installation It 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 Tool Note: The LED tool is a blind plug to be connected to the POWER connector. Follow these steps to install Adconâs RTU in the field: 1. 2. 3. 4. 5. Note: Review the installation area and choose the best site. 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). Unpack the pole set. 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). 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. The solar panel can be mounted under or behind the RTU, but be sure that the RTU does not shadow the panel. 6. WARNING 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. If you turn the fastening screws too tightly, you might damage the plugs. 7. 8. Attach the sensors to the INPUT connectors and the solar panel to the POWER connector by turning the plugsâ fastening screws clockwise until secure. Secure the extra length of the sensor cables to the pole with UV resistant cable ties. CHAPTER 2 Installing the RTU This 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 youâll 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 RTU More about the LED tool The 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 answerâthis 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)âthis 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 Adconâs RTU charger (item number 200.733.550). The addTIMER extension for addVANTAGE Pro 5.3 and newer In 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. 10 CHAPTER 2 Maintaining and servicing the RTU To configure the addSWITCH RTU in your A840 or A850 Telemetry Gateway and addVANTAGE Pro, please check the respective user guide. Maintaining and servicing the RTU A 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. Donât 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 battery The internal battery supplies 6.2 volts and consists of a NiMH pack. The internal electronics manage the batteryâs 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 deviceâs expected operation time on a fully charged battery under various conditions. Table 1. addSWITCH Device Operation Time Note: Radio Activity Valve Actions Average Consumption (mA) Estimated Operation (days) No none 0.667 100 Yes none 0.833 80 Yes 40 1.8 37 âRadio activityâ 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 âBattery lowâ 11 CHAPTER 2 Maintaining and servicing the RTU messages), 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 panelâs surface with a thin layer of dirt, effectively reducing its power output. Surrounding vegetation can also lower panel efficiency. Replacing the battery If 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. 2. The battery pack is connected to the electronics board by means of a PCB connector. Remove the battery packâs plug from the PCB connector, as shown in Figure 4. Figure 3. Removing the addSWITCH Lid 12 CHAPTER 2 Maintaining and servicing the RTU Figure 4. Unplugging the PCB Connector 3. 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 Pack 4. WARNING 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. Be sure to mount the rubber gasket properly, so that the unitâs 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. 13 CHAPTER 2 Maintaining and servicing the RTU 8. Screw the four cover screws back in, applying a moderate force. 14 15 Chapter 3. Performing Advanced Functions With 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 doâthe 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 connectors The addSWITCH devices have cable attachments called connectors. The connector type determines how the device communicates with the sensors or the computer. The RTU connector The 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 3 Understanding connectors connector 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. SBAT CNT3 AN0 CNT0 CNT2 CNT1 GND Figure 6. Pins on the I/O Connector (Top View) The POWER Connector The 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 baud Figure 7 illustrates the connections available at the POWER connector. Ext Power Battery RxD TxD Ground 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. 16 CHAPTER 3 The VALVE Connector Short Battery (5.6 to 10 Volt) Figure 8. A724 Connection with External Battery If you want to use the internal battery with a different power supply (charger) than the provided solar panel, disconnect the solar panel and use the configuration shown in Figure 9. Short Charger (9 to 10 Volt, 100 to 300 mA) Figure 9. A724 Connection with External Power Supply And if you want to use an external battery with a different power supply (charger) than the provided solar panel, disconnect the internal battery and solar panel and use the configuration shown in Figure 10. Short Charger (must fit the Battery) Battery (5.6 to 10 Volt) Figure 10. A724 Connection with External Battery and Power Supply The VALVE Connector The VALVE connector (Figure 11) is used to connect up to four latching solenoids. The connector is a 6-pin SWITCHCRAFT connector (EN3P6F, counterpart is the EN3C6M). The A724 comes with a 0.5m cable with flying ends. A standard insulating screw joint can be used to connect the solenoid. It is up to you to protect this insulating screw joint for outdoor usage. 17 CHAPTER 3 The VALVE Connector Valve4 Valve1 Valve3 COM Valve2 COM Figure 11. 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. Table 2. Valve Connector Signals and Cable Colors Signal Note: Switchcraft pin Color Valve1 white COM brown, green Valve2 yellow Valve3 gray COM pink, blue Valve4 red 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: WARNING 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. 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). 18 CHAPTER 3 Communicating with the RTU Communicating with the RTU You 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. 2. 3. 4. 5. Note: Open a Hyperterminal window. Select the appropriate serial port and click OK. Configure your terminal as follows: ⢠19200 baud ⢠1 stop bit ⢠8 data bits ⢠No parity ⢠No protocol (neither hardware nor software) Select OK to open the terminal window. Press Enter to generate a response in the window. Beginning with the A724 Series 4, RTUs operate in two modes, bootloader and firmware. Booting the RTU Note: 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 V1.7 Copyright (C) Adcon Telemetry GmbH 2009 Presswithin 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. 19 CHAPTER 3 Upgrading the Firmware In bootloader mode, the command line interfaceâs prompt is the character >. Therefore, to reboot the RTU just type the following after you see the > prompt: reboot An 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 download version ... show the version of the bootloader state ... show the board state reboot [id] ... reboot the RTU firmware ... start the firmware help ... display this help text Note: For some commands, such as the reboot command, you can supply the ID of the RTU. Firmware Mode When 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 RTUâs identification number (for example, 41239) and error code (in this example, 0) are displayed. After another moment, the firmware modeâs command line interface prompt is displayed (#). If you need to return to bootloader mode when youâre in firmware mode, enter the Reboot command at the prompt. See âUsing terminal commandsâ on page 24 for commands available in firmware mode. Upgrading the Firmware Note: This section is included for informational purposes. You will rarely need to upgrade the firmware. However, when you do need to do so, 20 CHAPTER 3 Upgrading the Firmware you will work within a Windows HyperTerminal window on your computer. Before upgrading the firmware, you must reboot the RTU to access the bootloader modeâs 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 bootloaderâs signon message when you start it. At the bootloader modeâs > prompt, enter the Version command. In firmware mode, enter the Reboot command and look at the signon message. In firmware mode, enter ver at the # prompt. Now youâre ready for the upgrade. 1. At the â>â prompt, enter the following command: upgrade 115200 The 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 to start flashing. 2. 3. Note: Select FileProperties to open the hyperterminalâs Properties dialog. Select a com port for the Connect using field. 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 portâs Properties dialog (Figure 12 shows a COM1 com port). 21 CHAPTER 3 Upgrading the Firmware Figure 12. Hyperterminal and Com Port Properties Dialogs 5. 6. 7. 8. In the Bits per second field, select 115200. Select OK in the com portâs Properties dialog to close it. Select OK in the hyperterminalâs Properties dialog to close it. Back in the hyperterminal window, press Enter to continue the upgrade. --------------------------------------------------The current firmware image must be erased for the upload. If you continue now, you *MUST* upload a valid firmware image for an A724_S4! Continue? [y/n]: WARNING When you continue with the upgrade process, any existing firmware image in the RTUâs flash memory will be erased! You must supply a valid image for upload or the RTU will have only bootloader capabilities (that is, it will have no radio capabilities). 9. Enter Y to continue the upgrade. The bootloader starts sending the letter C (for connect) Starting flash blankcheck and erase process. . . done --------------------------------------------------Start the Y-modem upload now! Starting CCCCC 22 CHAPTER 3 Serial communication protocol 10. From the hyperterminal windowâs menu bar, select TransferSend 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 Image 11. 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: firmware Serial communication protocol This 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 command The commands have the following format: ID Command Param1 Param2 ... ParamN ⢠Note: 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 nodeâs 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. 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. 23 CHAPTER 3 Using terminal commands ⢠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 answer The 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 âReturned errors listâ 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 commands The 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. Note: You can type uppercase or lowercase characters because the commands are not case sensitive.

PARAMETERS The first parameter is the 12-bit bitmask to specify the port bits that will trigger a digital port event. 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! 27 CHAPTER 3 Using terminal commands RETURNS The current settings. REMARKS GET/SET. REMOTE Yes, via XCONF. EXAMPLE This example shows a setup where a status change of one of he valve ports will throw a digital port event.

The dynamic slot switching function checks whether the measurement value of a given sensor matches the given condition, then switches between two operating modes: 1ânormal mode (when the condition is false and the lock timer is zero) 2âexecution 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 1âsensor type (0=none, 1=internal battery, 2=anlg, 3=port, 4=counter). 2âsensor address (channel number as in the ANLG and PORT command). 3âlimit type (0=above, 1=below, 2=out of range, 3=within range). 28 CHAPTER 3 Using terminal commands 4âthe limits (depending on limit type): For type=0 /1âone limit.

Note: The limit values are raw adc values (0-2.5V=0-65535). 5âa bitmask specifying for which connector the SLOT value must be changed (0=internal, 1..4=I/O-A..I/O-D, 5=Valves, 6=SDI-12). 6âlock time for the active state. WARNING Timeout values lower than 3600 seconds can lead to an excessive use of the data storage. This can reduce dramatically the lifetime of the device. 7âSLOT value for exception state. 8âSAMPLE value for exception state. 9âSLOT value for normal state. 10âSAMPLE value for normal state. RETURNS The actual setting, the lock timer value (0=inactive, 1-43200=active) and the number of dynamic slot switches since power-on of the RTU. REMARKS GET/SET. REMOTE Yes.

Channel 0 uses the internal sensors such as temperature and battery voltage. Channels 1-4 are the virtual connectors IO-A through IO-D. The four counter inputs of the A724 Series 4 are mapped to virtual connectors IO-A through IOD, although the A724 Series 4 has only one sensor connector (INPUT). Column 6 of channel 1-4 are the counter values. The analog input is mapped to column 3 of channel 1. In the above example, the analog value is 64 and counters 1-4 have a count of 9, 12, 1890, and 19 respectively. The actual valve state is displayed in column 2. The decimal value 240 shows that all four valves are inactive (high=inactive). Note: The number 240 displayed in binary form is 11110000, which means bits 7 to 4 are high. Commands for controlling the valves This section describes various commands you can use to control the valves. Switching the valves The valves can be controlled by the following commands shown in Table 3. 40 CHAPTER 3 Commands for controlling the valves Table 3. addSWITCH Commands Requested action addSWITCH A724 command Open Valve 1 for n seconds PORT 212 d n Open Valve 2 for n seconds PORT 213 d n Open Valve 3 for n seconds PORT 214 d n Open Valve 4 for n seconds PORT 215 d n Close Valve 1 (before time n has elapsed) PORT 164 Close Valve 2 (before time n has elapsed) PORT 165 Close Valve 2 (before time n has elapsed) PORT 166 Close Valve 2 (before time n has elapsed) PORT 167 n is the desired run-time in seconds (max. 65535, approximately 18h) and d is the startup delay in seconds (max. 65535, approximately 18h, the recommended minimum is 1s).
