Chapter 2 ________________________________________________ Configuring Optional Hardware CHAPTER 2 CONFIGURING OPTIONAL HARDWARE This chapter contains information needed when configuring optional hardware. The optional hardware described here includes Vaisala Digital I/O Module and Nokeval 7470 Serial to Analog Converter. Digital I/O Module Digital I/O Module QMI108 is used to extend the I/O capacity of MAWS. It is equipped with eight inputs and eight outputs.
Technical Reference_________________________________________________________________ 0506-036 Figure 1 2. Hardware Setup View: Digital I/O Configuration Proceed to the Timers view to configure the on/off cycle for the selected outputs (0 and 4).
Chapter 2 ________________________________________________ Configuring Optional Hardware In the example, the configuration is as follows: - Test output 0 toggles between on and off in a one-minute cycle. - Test output 4 is on for one minute before each full hour. Alternatively, you can control the outputs with alarms, for example, by activating the output signal when the alarm condition is met. Proceed as follows: 1.
Technical Reference_________________________________________________________________ In the Reports view, the input statuses are available as individual variables IN0 through IN7 and combined as bits into a single status word ALL. The input module status is also available as for the sensors, refer to Figure 4 below.
Chapter 2 ________________________________________________ Configuring Optional Hardware current inputs are used instead of a serial data interface. The converter can be controlled through an RS-485 serial line. As Nokeval converters are fully configurable, knowledge on these devices is required before taking them into use with MAWS. It is possible to add one or more converters to a single RS-485 serial line with MAWS. For further details, see the applicable Nokeval user's manual, available at www.nokeval.

Technical Reference_________________________________________________________________ Sensor Monitoring To test if the communication between MAWS and the QUATRO-IND sensor works properly, proceed as follows: 1. Start MAWS Terminal and open the maintenance connection. 2. Check communication by opening a connection between the maintenance port and sensor. When supposing that the QUATRO-IND sensor is connected to COM1).
Chapter 6 _________________________________________________________________________ Each parameter is updated once a second, so you should see four messages received every second. If no data is received, check that: - QUATRO-IND is powered up, - wires are correctly connected, and - serial parameters are correctly set in MAWS Lizard. Finally, close the terminal connection: /> close 3. Check that MAWS receives parameters from QUATRO-IND correctly.
Technical Reference_________________________________________________________________ In case of an error, the response can be one of the those listed in Table 11 below. Table 11 Error Responses and Probable Causes Response Target component not found Invalid ID Status:2 Value:.. Probable Cause The component is misspelled or QUATRO-IND has not been configured The data item name is misspelled or the F flag at the end of the command is missing The parameter is not received correctly.
Chapter 7 ____________________________________________ Configuring Serial Sensor Interfaces CHAPTER 7 CONFIGURING SERIAL SENSOR INTERFACES This chapter contains information needed when configuring serial sensor interfaces, that is, connecting sensors that use serial communications to the MAWS301 weather station. Note that this chapter contains only instructions for configuring the interface, not the sensor itself.
Technical Reference_________________________________________________________________ For most of the sensors, wiring depends on the application. You should therefore also have additional wiring instructions and drawings available. Physical Interface MAWS logger has five different types of optional serial interfaces available for the sensor connections. For details and wiring for the interface modules, refer to the MAWS user manuals listed in the Related Manuals table on page 6.
Chapter 7 ____________________________________________ Configuring Serial Sensor Interfaces Data Acquisition Methods In general, there are two alternate methods to connect a serial sensor to the MAWS weather station: 1. Automatic transmission - Device transmits the measurement results automatically - Only one device per serial port - Physical connection can be RS-232 or RS-485 - Higher data throughput 1.
Technical Reference_________________________________________________________________ Configuring Serial Line Parameters NOTE MAWS does not perform any automatic configuration of the connected sensors. You have to perform the configuration and store it manually by using the sensor's own service interface. For sensors without a human readable command interface, extra MAWS shell commands are provided. For further information, refer to detailed sensor interface descriptions or separate Technical References.

Technical Reference_________________________________________________________________ Configuring Sensor Interface Serial sensors have and use their own configuration interfaces. In addition to defining the communication parameters, there is typically very little to configure with Lizard setup software. Proceed as follows: 1. Add and configure the communication interface module using the Hardware Setup view, see Figure 71 below.
Chapter 7 ____________________________________________ Configuring Serial Sensor Interfaces 0506-051 Figure 72 Hardware Setup View: Defining Transmit Control Parameters You do not need to select the Service connection enabled option in order to have service access to the sensor. Selecting this option in fact enables service access to MAWS through the port. 2. Proceed to the Equipment view to add and connect the sensor, see Figure 73 on page 110.
Technical Reference_________________________________________________________________ 0506-052 Figure 73 Equipment View: Adding and Connecting the Sensor Note that serial sensors do not have default connectors, so you need to connect the sensor manually to the selected port. The first number of the connector identifier MODX/X (for example, MOD1/1) indicates the piggyback slot: 1 is the one closer to the battery holder and 2 is the bottom one.
