3. Figure 27 Sample Options page The Sample Options page is used to configure a sample of measurements Typically a sample will contain several measurements although it could contain only one measurement The meaning of some of the settings on this page will depend on whether this script was set for continuous sampling or scheduled sampling The Start Up Options box configures how the script starts up allowing the script programmer to start the script before the HydroDAS is fully deployed and initiate the script at a later time or simply delay the start of the script for long enough that deployment equipment can be moved away etc The time setting in Delay Sampling for will determine how long the HydroDAS remains in a sleep state after the script is started up The next two options determine whether the sleep switch needs to be toggled to start up the script If Wait for switch then start up is selected the first line of the script will be a sleep statement so running the script will put the HydroDAS to sleep Once the HydroDAS is awoken the countdown specified for Delay Sampling for will begin and then either continuous sampling or scheduled sampling will begin 52 The Shut Down Options box will only appear if Continuous Sampling was chosen on the previous page If Go to sleep at the end of the script is checked the HydroDAS will go into low power sleep when continuous sampling is done D

12. Start data commands Likewise some stop commands take a while to take effect so you can specify them with a minimum pause so that power and communications will not be cut off before the command has completed The Priority Options box has two settings Power priority and Data priority Power priority controls the sequence in which instruments are turned on when several instruments are turned on at once The instrument with priority 1 is turned on first followed by the instrument with priority 2 etc This allows the user to turn on instruments with major start up power requirements first so that ample current is available and so that other instruments are not affected Data priority controls the sequence in which data is requested from instruments when several instruments are polled for data at the same time This is useful when that output from several instruments are routed to the same channel for tabular display in most cases applies only to analog output devices 7 2 3 Data Capture Options Page Figure 21 Automatic Data Capture Options The Automatic Data Capture Options page appears only for serial output instruments and controls how data is captured from the instrument when the Go and Stop buttons are presses or in autonomous mode scripts written by the Script Wizard see Section 7 4 Some of the options will be enabled and others will be disabled depending on which value was select

23. 1 Data Protocol Functions The key features of the protocol are time tagging error detection correction and data multiplexing Each packet is assigned a time tag so that sequences of data can be reconstructed 13 after transmission Each packet also includes a checksum that allows detection of transmission errors Data multiplexing means that data from different sources are packed together for transmission but in such a way that they can be reassembled into independent data streams after they are received Packets may be assigned to one of 256 channels When packets are received by DASHost individual channels may then be directed to files serial ports and terminal windows on the host computer Typically a channel will carry data received on a particular serial port of the sub unit but under the control of HydroScript any type of data strings files analog data etc may be assigned to any channel HydroDAS also reserves a few channels for particular types of information it uses such as file directories and instrument status messages HydroDAS can be set to one of three protocol modes for its host interface described below Use extreme caution if changing modes because different host software is required for the different modes DASHost only directly supports the default error correcting protocol 4 11 2 Error correcting Protocol Error correcting protocol is the standard interface mode In this mode each packet of data sen
