It is also designed to be very easy to install on your system using an automated installation program. SYSTEM REQUIREMENTS: Since you’ve acquired the DataTrace® RF System, what do you need in the way of hardware (physical equipment) to get your system up and running? This section will provide you with the answer to that question. Your computer’s Guide to Operations and/or your computer supplier can explain the correct set up your computer system hardware if you have any questions. The DataTrace® RF program is designed for use under a Windows 32-bit Operating System, such as, Windows 2000, or Windows XP. The following is the minimum system requirements for operating the DTRF program. Pentium 133MHz 32MB RAM 40MB of free hard disk space Windows 2000 or XP Operating System 1 Free USB Port 1 CD ROM drive 1 Mouse As indicated, these are minimum requirements; we strongly recommend additional system capabilities, especially the processor and RAM. They will greatly enhance the performance and usability of your DataTrace® RF system along with other programs on your computer. INSTALLING THE DataTrace® RF PROGRAM: DataTrace® RF includes an automatic installation program. If you have installed other Windows programs you are familiar with this process. After the installation of the DTRF program, leave the CD in the drive and connect the Interface to the USB port. This will start the installation of the USB drivers for your DataTrace system (see the USB Installation section below). 1. Insert the DataTrace RF CD-ROM into your computer’s CD-ROM drive. Open Windows Explore to the CD drive and double click DTMPRF.msi. The installation program starts and the “DataTrace RF Installation” window is displayed. Follow the instructions presented by the Installation Wizard. 2. Clear an area next to your computer as a work area. You will need access to a USB port on your computer. 3. Lay the PC Interface System components next to your computer for easy reference. These components include: the Interface Module, the USB Interface Cable, and the DataTrace® RF CD (which should be in the computer’s CD drive). 6 of 27 pages DataTrace USB Installation Instructions The installation of the DataTrace USB Interface Drivers is a simple procedure where a new Serial Port is created which is related to the USB PC Interface module. The USB drivers are included on the DTRF CD. Once installed, the Interface can be removed from and reinstalled to any USB port on the computer. The DataTrace RF program and the DataTrace for Windows (DTRF) program will recognize the PC interface as a known hardware and ready for communication immediately. We recommend that the DTRF and/or DTRF program be installed first, followed by the USB drivers. Windows will identify that new hardware has been connected when the USB cable and PC Interface are plugged into the USB port for the first time. This will trigger the Windows New Hardware Installation wizard. It is important to note that TWO sets of drivers need to be installed for the proper function of the DataTrace USB system, they are: DataTrace MPIII USB PCIF and USB Serial Port. Both must be installed. The following instruction set assumes that the DTRF and/or DTW program is already installed. Driver Installation Be aware that two installations are occurring automatically during this process. The first installation is the DataTrace PC Interface itself. Following that installation, the USB Serial Port is installed. Do not become concerned when the installation process seems to be repeating itself, they are in fact two different installation procedures, and this is normal. Connect the USB cable to the back of the PC Interface module, and then connect the other end of the cable to an open USB port on your computer. Soon after this connection is made a “balloon” will appear on the bottom right of your screen stating that “New Hardware Found” and identifying it as “DATATRACE MPIII USB PCIF”. 7 of 27 pages The following “Found New Hardware Wizard” screen will appear within a few moments: • • • Verify that the CD with the USB Drivers is in the CD drive on your computer. Under the “What do you want the wizard to do?” select “Install the software automatically (Recommended)” Click “Next”. The next screen will appear as the appropriate files are retrieved and installed from the CD. 8 of 27 pages The following message will appear during the installation process. Ignore it by pressing “Continue Anyway” button. The installation process will continue. 9 of 27 pages When the files are retrieved and installed, the Next button will become active. Click the Next button and the following screen will appear indicating that the DataTrace MPIII USB Interface installation is complete. Click the Finish button. The second installation program for the USB Serial Port will now start. Many similar screens from the DataTrace USB PCIF installation will appear again, except they now indicate the “USB Serial Port” is being installed. As before a “balloon” will appear on the bottom right of your screen stating that “New Hardware Found” and identified as “USB Serial Port”. 10 of 27 pages The following “Found New Hardware Wizard” screen will appear: • • Under the “What do you want the wizard to do?” select “Install the software automatically (Recommended)” Click “Next”. The next screen will appear as the appropriate files are retrieved and installed from the CD. 11 of 27 pages The following message will appear again during the installation process. Ignore it by pressing “Continue Anyway” button. As before, the installation process will continue. 12 of 27 pages When the files are retrieved and installed, the Next button will become active. Click the Next button and the following screen will appear indicating that the DataTrace USB Comm Port installation is complete. Click the Finish button to complete the installation program. You are now ready to use your DataTrace RF system. Congratulations. Now that your DataTrace® hardware is connected to your computer and you have installed the DataTrace® RF program, you are ready to work with your system. Create a short cut to the DTMPRF program on your desktop. Double click the DataTrace® MPRF icon, which will start your DataTrace® RF program. DataTrace RF Operational Instructions DTRF will automatically search for connected interfaces. It is important to connect your USB interface(s) to your computer’s USB ports prior to starting the application. When DTRF is first accessed, the Main tab screen is displayed, which includes access to screens for Programming (starting), Reading, Testing and Viewing the Real Time data of MP-RF type Tracers. 13 of 27 pages Setup Before performing any of these functions, the Comm port setup must be defined in the Setup tab. Once setup selections have been defined following initial installation, it is not normally necessary to adjust them again; the application will retain its settings from session to session. Clicking the 'Setup' Tab will display the Setup screen, with the following options that can be used to configure your DataTrace RF system: Data Display, Comm Ports, Preferences, and Lethality. 'Comm Ports' Settings Note that the only setting that must be established initially is the Comm Ports. Other items may be left at their factory default configurations or changed based on your needs. 14 of 27 pages There are three types of DataTrace loggers, the SMT (also known as MPII or FRB types, depending on model), the MPIII and the MP-RF. The SMT type uses an older style PC Interface connected to a serial comm port (RS-232-C). MPIII and MP-RF types have a newer Interface designs usually connected to a USB port. However, an MPIII can be programmed and read with an MP-RF type and vice versa. Finally, to receive MP-RF radio data, a MP-RF style interface (hereafter called the Host) with radio antenna is required. Since the MP-RF receiver must be programmed to match the Tracers, the MP-RF Tracers should be programmed on the MP-RF Host intended to receive their data. Set the comm port for each of the interface types you intend to use. The same Comm port designation can be used for multiple Interfaces. 'Data Display' Parameters Select the desired units of measure (e.g. for temperature °C or °F) and the number of decimal places to be displayed for each parameter. 15 of 27 pages 'Preferences' Settings The preference settings affect how the software behaves when programming or reading Tracers. Most options are self-explanatory. The 'Default Start Time Minutes' option defines how far in the future data logging will begin when first entering the Program Tracers screen, rounded upward as defined by the 'Round Default Start Time boundary' setting. For example, for a boundary setting of 15 minutes, if hh represents the starting hour, the start time is forced to hh:00; or hh:15 or hh:30 or hh:45. While this boundary rounding is only specifically required for the synchronization of MP-RF radio communications, it is applied to all Tracer types. Data Saving Preferences: DTRF can save data to the standard DataTrace for Windows database (Version 4.04 or greater) or it can save data in text files (located in the subdirectory "Data" where DTRF is installed (usually C:\Program Files\DTMPIV"). Options are provided to save collected data into DTRF's 21 CFR Part 11 compliant database (allowing full use of all standard DTRF reports and data basing functions), to the text files, or to both. DTRF will verify the presence of DTRF and an appropriate version, and generate an error message if there is an incompatibility. The text files are automatically named and are tab separated, allowing for easy importing into a spreadsheet or other program. 16 of 27 pages Programming Tracers Clicking on the Program Tracer button from the Main tab will launch the Program Tracer Wizard. This wizard consists of four screens which are accessed sequentially by the conventional 'Next' or 'Back' buttons. The 'Next' button will not be enabled (will not respond) until all required information on the current screen has been properly entered; status messages will be displayed for missing or erroneous information. Of the four screens in the wizard, two are applicable only to MP-RF Tracers. If you do not use this type of Tracer, there is an option in the Setup\Preferences to skip the MP-RF screens. Any attempt to program an MP-RF Tracer when these screens have been skipped will result in an error and require proper completion of all screens. While DTRF will allow programming of all types of Tracers, the user must select which type is currently being programmed. Select the appropriate type of Tracer from the dropdown list in the upper right corner of the screen. While the Tracer type can be changed at any time during a programming session, we recommend grouping the Tracers by type and program each type in its entirety before proceeding to the next group.(e.g., you may program MP-RF's, then change to MPII and program them with the same parameters). Program Wizard Screen # 1 Screen #1: "MP-RF Radio Options" Select the MP-RF option to enable the Tracer's radio. Note: The radio function is a significant draw on the battery; use the radio function only when it is needed. Note: The radio is not to be used for data acquisition during the calibration procedure. When the Radio function is enabled, the following Radio Configuration Parameters will be shown: 17 of 27 pages Number of Tracers in Group: Each MP-RF Tracer requires a specific time slot for communications, consisting of a 1 second window some number of seconds after the Tracer logs data. This time slot is called Member Number, and DTRF will assign it automatically. The Member Number must be less than the sample interval (in seconds), therefore the Number of Tracers in Group determines the minimum allowable interval; this minimum interval is displayed. This information is displayed on the second screen of the wizard. Channel Number: This value determines the zigbee channel the radio will operate on. Allowed values are 0 through 15. If there are other zigbee devices in use (which will typically also have a configurable channel number), it would be preferable to use a different channel. If there are other MP-RF users, or it is desired to keep distinct groups of MP-RF Tracers, each user or group should use a distinct channel. If Repeaters (a type of MP-RF that rebroadcasts data) are to be used in this system configuration, a separate channel should be assigned to it in order to allow longer range. More details on repeaters are given at the "View Real Time" section, which contains diagnostics for determining the presence of non-MP-RF communications. Advanced Configuration (For advanced users only): When checked, allows the user to access the advanced configuration utility. This utility allows the user to bypass DTRF's automatic assignment of Member Number, Channel and some other radio parameters, and configure the Tracers manually. Details are given in Appendix TBD. Program Wizard Screen # 2 Screen #2: "Data Logging Parameters" 18 of 27 pages Start Time and Sample Interval: Enter the desired Start Time and Sample Interval. Specifically, the date and time the Tracer(s) are to begin logging data and the interval for data collection. Run ID: IF desired, enter a Run Identification, up to 8 characters. It may be the same for all Tracers, or different if desired. The Enable Auto-Numbering option allows automatic assignment of a unique Run ID to each Tracer. Program Wizard Screen # 3 Screen #3: "MP-RF Logging Parameters" MP-RF Tracers will stop logging data based on the selected option. The MPII and MPIII types do NOT support these options. Stop Logging When Memory is Full: This option behaves the same as MPII or MPIII types, and is dependant on the type and memory capacity of the Tracer (for MP-RF, 8000 points for a single channel temperature Tracer, 4000 for dual channel such as RH Tracers) Continuous Loop Logging: The Tracer enters into a continuous loop and will never stop logging or reporting measurements, where the oldest data is overwritten by newer data when the memory is filled. Caution: When a Tracer is read, the reported Start Time will be the time of the oldest available point. Note however, if Continuous Loop Logging is enabled, the originally programmed Start Time may have been overwritten. When a group of Tracers using this mode is read, it is possible the reported data will have different starting times, which will cause difficulty when trying to generate complex reports and graphs. This mode is recommended only for those applications where the intent is simply to monitor real-time. Stop at a Defined Date and Time: Self-explanatory. 19 of 27 pages Program Wizard Screen # 4 Screen #4: "Program Tracers" Review the Start Time and Interval settings. Modify the Run ID if desired. Within the Program Tracers screen the Start Time and Sample Interval may not be changed. Use the 'Back' button to go back and edit these values if desired. Note: After the first Tracer has been programmed, the 'Back' button will not be available, and the Start Time and Interval are fixed for the current programming session. Place a Tracer in the interface and verify the selected Tracer type (upper right corner) matches. Click the Program button to apply the settings to the Tracer. Upon successful completion "Last Unit Programmed" will show the serial number of the programmed Tracer. A "Tracer Programmed" message will also be generated to indicate programming success, unless this message was disabled in the system setup preferences. Remove the Tracer from the interface and program the next one if desired, alternatively, the Tracer type may be modified, and a different type programmed. Batch Mode Programming: If this option is selected, a programming loop is initiated when the Program button is clicked, and the Program button will change to "Stop". Upon successful programming, "Waiting for Next Tracer" will be displayed; remove the Tracer from the interface and put the next one in; programming will occur automatically. When all Tracers of the selected Tracer type have been programmed, click "Stop". If you wish to program more Tracers of a different type, select the type and batch mode can be restarted. Tracer type may not be changed while batch mode programming is in progress. Batch mode is also aborted automatically by any communications error; the “Stop" button will change back to 'Program' and after noting the error and/or taking corrective action, 'Program' must be clicked again to start the programming loop. If during programming the current time surpasses the program Start Time, programming will no longer be allowed. This condition will be indicated by the color of the Start Time 20 of 27 pages changing to red. Should this occur, Start Time can be incremented in whole Sample Intervals by use of the adjacent 'Increment' button (visible only when this condition exists). If an attempt is made to program a Tracer which contains data which has not been read or saved, a " Tracer has not been read" warning message will be displayed, unless this message was disabled in the system setup preferences. At any time the “Program Report” button can be clicked in order to see a listing of the Tracers programmed during the current session. When all Tracers have been programmed, click the 'Close' button to return to the Main screen. Reading Tracers Click the Read Tracers button from the Main screen to access data retrieval functions. To read a Tracer place it in the interface, verify the appropriate Tracer type is selected (upper right corner) and click the 'Read' button. Note: When entering the Read Tracers screen, a Tracer may be read automatically if the "Auto-Read on Entry" option was selected is system setup preferences, the auto-read will be attempted using the Tracer type last employed by the Read, Program or Test Tracer screens. Three views (tabs) are provided; a Summary view, a Profile view consisting of the data and time it was logged, and a Graph view. Tracers may be read regardless the selected view. Summary View Profile View 21 of 27 pages Graph View The Y axis of the graph (and the second Y axis if the Tracer has two channels) can be scaled by clicking on the axis; An inquiry will be generated for the desired lowest and highest axis values. Adjusting the X axis range is not supported at this time. Data is automatically saved immediately after the Read is complete. Data is saved in the format(s) specified by the Save Data options in system setup preferences. View Real Time Data The View Real Time button accesses a screen which allows incoming MP-RF radio data to be viewed and logged. This screen can only be accessed if there is a MP-RF interface connected to the computer. Data display will begin as soon as radio data is received. In general, this will happen once the Tracers reach the programmed Start Time. Data can only be received for Tracers transmitting on the Host receivers channel setting (displayed in the upper left corner). At the top left of the screen are the menu items "File", "Edit" and "Utilities". The functions provided by these menus are context sensitive, that is, their action depends on what is being viewed. For example, Edit>Copy will copy data if the user is currently viewing real time data, but would copy the Graph if that was being viewed. Similarly, the contents of the Utilities Menu will change depending on which view is invoked. There are five (5) views provided, accessed by the tabs. Real Time The Real Time screen supports the ability of MP-RF Tracers to transmit via radio the measured data. The data is transmitted between data acquisitions (sample intervals). All transmitted data is also logged within the Tracer and can be retrieved through the Read Tracer process. The successful reception of radio data is contingent upon many factors beyond the control of Mesa Laboratories, Inc and DTRF, including constraints such as 22 of 27 pages distance, other interfering radio sources, proper system configuration, walls, floors, and other obstacles, and perhaps most importantly, Faraday's law, which states that radio signals will not travel through conductive materials (e.g. metals). If an MP-RF Tracer is placed in a sealed metal container, there can be very little expectation of successful radio transmission. However, for ovens, autoclaves, metallic freezers or sterilization chambers there is a good probability of radio communication if there is a non-conductive gasket employed on the door seal, or some non-conductive portion of the enclosure which has at least one dimension longer that 6" (the wavelength of the radio signal). Conditions such as these may limit the distance of transmission, requiring the Host to be placed relatively close to the Tracers, or using a repeater. In general, prior to actual use, it is advisable to perform some preliminary testing to verify radio communications feasibility and performance. While it is common that some radio data will not be received (90 % reception is a stated industry standard), DTRF and the MP-RF Tracers have unique features for retrieving missed data. This process occurs automatically, but only when communications are good; getting all data via radio may require the user to place the Tracers near the Host (good communications) to retrieve any missing data points after process completion. The Real Time view displays incoming radio data from MP-RF Tracers in a columnar format. The display will include the Tracer's Serial Number, Run ID, and the measured value(s) with units of measure. Other information can also be displayed, customizable by clicking the Display Options button and selecting the desired options, which include: Alarms: When enabled, the measured value is evaluated per the adjacent alarm settings. The value is displayed in black when normal, red if the High Limit is exceeded, or blue if lower than the Low Limit. Time Stamp: The date and time the data was measured. Tracer Start Time and / or Interval: The current settings of the Tracer Tracer Reading Number: Self-explanatory, it may be used to determine how soon the Tracer's memory will be full or how much data there is to read. Four diagnostics are provided: Group ID and Member Num.: The group ID is normally the numeric portion of the serial number of the Host receiver. The Host will receive data from any Tracer, but will only acknowledge and transmit instructions to those within its own group. Only data from the Host's own group can be logged, saved or graphed. The Member Number (discussed at Program Tracers) should be unique for each Tracer. If two Tracers have the same Member Number, their communications efficiency will be greatly diminished. Problems with Group ID or Member Number are usually caused by different groups of Tracers being programmed for the same channel or being programmed on one interface and being received with a different Host (to do this requires using the Advanced Configuration option when programming). 23 of 27 pages Elapsed Seconds since Last Data Reception: should not be greater than the Sample Interval. Signal Diagnostics: Causes the display of three signal parameters: 1. dB is the radio signal strength of the signals received by the Tracer, 2. Host dB is the signal strength of signals received by the Host. Signal strength in the range of -20 db to -60 db are considered excellent, while a -98 db is a very weak signal. 3. Communications Mode is also displayed and has two states: • OK for normal radio communications, and • NB when the communications are not bi-directional. "NB" means that even though data is being received, the Tracer cannot receive any instructions, and some features (e.g. programming via radio) will not be allowed. Battery % Remaining: Self explanatory. Comm Fail Warnings Settings: Should communications fail, the displayed measured value will eventually be erased after the "Clear Data Display" number of sample intervals without communication has elapsed. The entire display row will be removed once the "Remove Display Row" number of intervals has passed. Show Summary: When set, a summary of the incoming data will be displayed, which includes the number of Tracers of each type and the minimum, maximum, average, spread and standard deviation of the current readings? Note on timing or availability of the displayed information: Each MP-RF transmission contains standard information which includes its serial number, data time stamp, the data and miscellaneous parameters. More detailed information such Tracer Start Time or Run ID is transmitted only when requested. When first viewing the display, the more detailed information may not be immediately available. Logging Warning: Radio data is not automatically logged or saved. To log the data, click the 'Start' button. The button will change to 'Stop', which will stop logging when clicked. Once a minimum of 3 rows of data have been logged, the graph will be available. The graph only displays logged data. Recovering Previous Data: If a logging session is started after the Tracers have already logged data, the pre-existing data can be retrieved. From the Utilities menu, 24 of 27 pages select "Recovery Previous Data", and enter the date and time of the first point to be recovered. The date and time must not be earlier than the start time of the Tracers (DTRF will verify). Upon entry of a valid date, the log will be populated with new rows and the data recovery process will begin automatically. Data recovery requires precise knowledge of the Tracer's Start Time and Sample Interval. Data recovery will not commence for a Tracer until such time as communications quality has been sufficient to retrieve this information. The speed of data recovery is also highly dependant on communications quality. At its best, the data recovery routine acquires 16 sequential readings per interval (for a dual channel Tracer this might be 8 temperature and 8 RH readings, or 8 intervals worth of data). While the designed functionality is intended to retrieve small amounts of missed data, this feature may be used like a Read Tracer via radio function; however, this may require a significant amount of time. It is left to the user to decide if reading the Tracer in the PC interface is more efficient. Data may be saved by clicking the 'Save' button; it will be saved in the format specified by system setup preferences. Warning: When saving data to the DTW database, 21 CFR Part 11 compliance and security issues will not allow any further modifications to the data file, which disallows the addition of new data. Subsequent radio data can therefore no longer be saved to this profile record. When using the DTW database, it is preferable to acquire all the data desired, then Stop the logging process and save the data. Should it be absolutely necessary to save new data to DTW, the existing data must be removed using the Delete option in DTW's Archive Profile function, an action which may also require security clearances (refer to the DTW manual for details). The 'Clear' button can be used to clear the existing data in preparation for a new logging session. If the data has not been saved a message will be displayed and the user is given the opportunity to abort and save the data. Warning: Pressing 'Start' will erase any existing data. If the data has not been saved a message will be displayed with the opportunity to save the data. 25 of 27 pages Network The network screen provides methods to control the Tracers via the radio. On the left-side of the screen is displayed the current Tracer network configuration, showing the Host, the Tracers, and any repeaters which may be in use. Program via Radio: MP-RF Tracers may be reprogrammed via the radio. Programming via radio does require that communications be bi-directional for all Tracers (DTRF will advise if this condition is not met). Programming is not allowed while data logging is enabled. To reprogram the Tracers, enter the new Start Time and Sample Interval, and click program. DTRF will transmit the new parameters to the Tracers and verify the reception of the command. Programming status will be shown in the network configuration diagram. After all Tracers have been re-programmed, DTRF will reprogram any repeaters and the Host automatically. The entire process will normally require 2 to 3 sample interval periods. Upon completion, a message indicating reprogramming is completed will be displayed. It is normal for communications to be interrupted for a few intervals or until the new start time arrives. Add a Tracer: This button adds a Tracer to the current group. In order to add a Tracer, a member number must be assigned to it (see Program Tracer for Member Number details). The new member number may not exceed the interval limit. Member number can be viewed in the real time display by selecting that option. If the Tracer to be added is replacing a malfunctioning one, it is preferable to use the malfunctioning Tracer’s member number. Place the Tracer to be added in the Host interface and click the button. Enter the channel (default to the host channel) and member number (defaults to the next available one). The Tracer will be programmed to start immediately at an interval which matches the group and logging data at the same time as the group. Upon completion, a message is displayed and the option to add another Tracer is given. Note that added Tracers will have different start times that the original group. Add a Repeater: This button adds a repeater to the current group. DTRF will ask for a member number (same as adding a Tracer), and the repeater's re-transmission channel. By default, the repeater will be configured to receive data on the channel currently assigned to the host. The host will be automatically re-configured to receive data from the repeater. Remove a Repeater: This button performs the inverse of Adding a Repeater. The repeater will be stopped, and the host will be reconfigured to receive data from the channel the repeater was receiving data on. Configure Host: A utility which allows manually setting the Host's channel and Group ID. Intended for advance network control and not normally used. 26 of 27 pages Spatial Map The Spatial Map provides a method of viewing incoming data against a backdrop consisting of a user defined picture, map, or graphical process representation, with the ability to position each Tracer's data relative to this image. For each transmitting Tracer, a box is available which displays the Tracer's data, Serial Number or Run ID identification. This box can be moved anywhere within the picture by dragging the box (while holding down the left mouse button). Setup options for the Spatial Map are accessed from the Utilities menu, "View Spatial Display Options", which includes a button to import a picture. The picture may be any standard windows picture file (e.g. bitmap or jpeg). A sample file named "3 shelves.bmp" is provided, which can be easily edited using any bitmap editor (e.g. Paintbrush.exe) to create a desired backdrop. Using the options, choose what information to display, and whether to apply alarms, which cause the backdrop of the data to change colors depending on the setting for the alarm values. The colors chosen for the alarms can be changed by double clicking the color box. Graph The graph is available only for logged data (see "Logging" section). The "View Options" button accesses the graph configuration options. These include choices for what to plot (Temperature, RH or both) and on which axis to plot (left axis standard, 2nd Y is the right axis). Options are also available to hide the legend, plot in black and white, and Auto-refresh the graph on reception of new data (if not selected, the graph is only refreshed once when entering the graph screen. Note: If a large number of Tracers or data is being plotted, and this action interferes (takes longer then the time between transmissions) with the reception of radio data, DTRF will disable the auto refresh option. 27 of 27 pages
