5 Chapter 1. Intr oduction This manual explains the hardwar e aspects of Adcon’ s addIT™ A72xx series, including installation issues and certain parameter configurations. The manual is divided into these chapters: • "Introduction," which gives some general information and document conventions.
CHAPTER 1 Introduction 6 The addIT A720/A723 RTU can be used in one of the following ways: • Installed in the vicinity of an Adcon remote measuring station (A730MD), the addIT RTU can use the A730MD station to relay its data to a base station (A730SD or A840).
CHAPTER 1 Conventions 7 A730MD remote station, but they cannot communicate with each other . • All addIT devices accept the standard Adcon sensors; however , the connectors ar e dif ferent. W aterproof connectors are used to pr ovide IP65 class pr otection.
CHAPTER 1 Introduction 8.
9 Chapter 2. Using the Base Station Y our addIT base station consists of the r eceiver (A720B), the power supply (A720PS), and addV ANT AGE Lite software. Note: If you ar e using the addIT RTU as part of an A730 system, this chapter does not apply to you.
CHAPTER 2 Using the Base Station 10 Make sure you’ve r eceived all the equipment and r ead through the instructions that follow . When you’re sure you understand them, you’re r eady to install your base station.
CHAPTER 2 Installing the base station 11 Follow these steps to install the receiver part of the base station. 1. Locate the best site for the receiver and mount a r od on the spot. The best site is usually on top of a roof or a mast. 2. Using the provided ring clamps, attach the r eceiver to the rod.
CHAPTER 2 Using the Base Station 12 Note: The serial cable ends are identical, so it doesn’ t matter which you use in each location. 3. Plug the appropriate ends of the power cor d into the power supply and the power source (outlet). Figure 3 shows the base station configuration.
13 Chapter 3. Using the R TU Remember that the addIT A720/A723 remote telemetry units (RTUs) can be used either with the A730 system or as standalone systems with the A720B base station. The base station is discussed in “Using the Base Station” on page 9.
CHAPTER 3 Using the RTU 14 Figure 4 shows an addIT RTU. Figure 4. addIT R TU Installing the R TU Installing addIT RTUs in the field is a fairly simple process. Y ou’ll perform a connectivity check with an LED tool (addIT devices don’t have a built-in LED like the A730MD stations do).
CHAPTER 3 Installing the RTU 15 on your application. Put a plastic cap on top of the rod to protect it. 4. Using a ring clamp, fasten the solar panel onto the aluminum rod. Ensur e that the panel is facing south (north if you are located in the southern hemisphere) and out of the way of the addIT RTU.
CHAPTER 3 Using the RTU 16 This completes the installation of your addIT RTU. If one of the I/O connectors is left unused, use the cap specially provided to pr otect it against moisture and dust.
CHAPTER 3 Maintaining and servicing the RTU 17 be fully charged after two consecutive sunny days, but you should get an LED light-up after several minutes of charging in the sunlight.
CHAPTER 3 Using the RTU 18 T able 1 shows the addIT devices’ expected operation time on a fully charged battery with 50 mA total consumption for the sensors, as described above.
CHAPTER 3 Maintaining and servicing the RTU 19 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 scr ews in the corner of the addIT RTU. 2. Gently remove the lid (the battery is fixed on the lid and is connected to the electronics boar d by means of a connector).
CHAPTER 3 Using the RTU 20.
21 Chapter 4. Performing Advanced Functions With the appropriate knowledge, you can configure the addIT devices in the field by using a hyperterminal window . T o configure the RTU, you will need a special serial cable adapter (not supplied, available from Adcon).
CHAPTER 4 Performing Advanced Functions 22 Device series Currently , two A720 device versions are in use: Series 1 and Series 2. in addition, since begin of 2001, Adcon introduced also the Series 3 model (A723). Y ou can determine which series a device is in any of these ways: • The VER command (see pages 29 and 52).
CHAPTER 4 Understanding connectors 23 The RTU connectors The addIT RTU uses standard 7-pin sensor I/O A and I/O B con- nectors (model Binder 702 and 712 series or equivalent) that are identical.
CHAPTER 4 Performing Advanced Functions 24 The RTU also has a POWER connector . Figure 8 illustrates the con- nections available at the POWER connector . Figure 8. addIT R TU POWER Connector (T op View) WARNING The RxD and TxD connections are not RS-232 compatible.
CHAPTER 4 Serial communication protocol 25 Serial communication pr otocol This protocol is based on a master sending commands and a node answering; the whole communication is conducted in plain ASCII, as strings. When exchanging numbers, they are r epresented in decimal format.
CHAPTER 4 Performing Advanced Functions 26 • Command is the string repr esenting 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).
CHAPTER 4 Using terminal commands 27 E XAMPLE SET OWNID 2003 C OMMAND SET PMP bl bh D ESCRIPTION Sets the power management parameters. P ARAMETERS bl is the lower battery level (the threshold wher e the charging of the battery is switched on) and bh is the higher battery level (the charging is switched of f).
CHAPTER 4 Performing Advanced Functions 28 WARNING Changing the above parameters may adversely affect the ability of the device to operate for extended periods under low solar radiation conditions when used with addV ANT AGE 3.
CHAPTER 4 Using terminal commands 29 E XAMPLE To set the RSSI threshold to 58: SET RSSI 58 Querying the actual configuration parameters Y ou can query an addIT to find out its actual configuration parame- ters ( GET the parameter).
CHAPTER 4 Performing Advanced Functions 30 • B – sends a broadcast frame and displays all the answers. Series 2 and 3 devices Note: W ith Series 2 and 3 devices, typing the command by itself is a GET command, while typing the command with parame- ters or variables is a SET command.
CHAPTER 4 Using terminal commands 31 C OMMAND FREQ CAUTION Do not change the fr equency of your device without reason. Apart fr om the fact that it may not communicate with the network anymore, you may also violate the applicable radio- communications laws in your country .
