Page 26Network Setup 51350-18 Initial Aquatrend Setup.fmSection 33.4 Network Setup A “network” is the connection of one or more devices (at least one must be asensor) to one or more AquaTrend Interfaces. A “device” can be an additional1720D sensor, Digital Display Module (DDM), Serial I/O module (SIO), SignalOutput Module (SOM), or a remote AquaTrend Interface.Up to eight sensors, eight Digital Displays, eight remote AquaTrendInterfaces, eight Signal Output Modules, two Serial I/O Modules and allnecessary power supplies may be attached to the network.The two procedures for adding device(s) to the network are presented insection 3.4.1 and section 3.4.2.3.4.1 Single Sensor SystemUse this feature when installing a complete system with no more than(1) Sensor (the 1720D Turbidimeter is being used in this example),(1) Master AquaTrend Interface, (1) SOM (as an integral part of an AquaTrendInterface or as a separate device), (1) SIO, (1) DDM, and (1) remoteAquaTrend Interface. During this procedure, the default device settings areaccepted and sensor measurements are automatically assigned toappropriate channels.1. Press the MENU key to access the Main Menu.2. Choose Network Menu.3. Select SINGLE SENSOR SYSTEM.A pop-up box will appear stating SINGLE SENSOR SYSTEMSEARCHING FOR UNCONFIGURED DEVICES.4. If the system is correctly installed, the display will next show a pop-up boxlisting all devices found. Press ENTER to install the single sensor system.5. After configuration, the display will show OPERATION COMPLETE.6. Press the DISPLAY key to show sensor data.3.4.2 Adding a Device to the NetworkTable 9 presents available device types. Follow the procedure below to add adevice. Repeat as many times as is necessary to add all needed devices tothe network.1. Press the MENU key to start from the AquaTrend Interface Main Menu.2.
