Introduction This manual is composed by: Menno ter Veld: and Ep Eding: For passwords and questions related to remote access to the Metabolic Research Unit contact the composers of this manual. 2. Pre-conditions for remote access to the WU-MRU As a remote user (guest, Fig.1) you have to login into our host computer (Host PC, Fig.1) from your own Virtual Private Network (VPN) at home or in your institute. To get access to our host computer the operating system of your computer and the browser installed on it has to be one of the operating systems/browsers described below under preconditions. You are authorised for access when we provided you a password by . The software package LogMeIn is used to give remote access to the host computer (see Fig. 1). To get access you need your address (LogMeIn ID for identification) and the by us provided password (only your address in combination with the password will give access to the host-pc). Preconditions: 1. Remote user has installed correct Virtual Private Network (VPN) 2. Remote user operating system is: 3. Remote user Browser Windows 7, Vista, XP, Server 2003, 2008 (all including 64-bit) Windows ME & 2000 (32-bit) Mac OS 10.4 (Tiger), 10.5 (Leopard), 10.6 (Snow Leopard), and 10.7 (Lion) on both Power PC and Intel-based Macs Internet Explorer 6 or later, with support for 128-bit or 256-bit recommend IE7 or later) Firefox 3.6 or later Google Chrome Safari 4.1 or later (Mac only) 4. Remote user is authorized by host for access to host computer based on: a. user ID (= your address) and b. password authentication (on request a password will be provided by Menno ter Veld (menno.terveld@wur.nl) 5. Remote user gets access by host administrator to specific subset of LogMeIn database tables, webcams etc. Figure 1. Remote access environment WU-Metabolic Research Unit (WU-MRU) 3

Access to the host PC You need to log in with your user name: 1. remoteuser1 (is given) and 2. the password received from WU-AFI 3. log on to: D (is already given see Fig. 4) After pressing on Login the desktop of the host pc will appear (see Fig. 5) Figure 4. Login screen. You have now started a remote session with the host pc, all your keyboard (except the ctrl+alt+delete combination) and mouse inputs are sent to the host pc. To obtain access to the host pc you have to click with your mouse on the ctrl+alt+delete combination key in the top bar menu, indicated with the red arrow in the screen view below (Fig.5). After you pressed on the ctrl+alt+delete you get access to the desktop screen (Fig. 6). Figure 5. Access to the host pc can be obtained by pressing the ctrl+alt+delete combination key in the top bar menu. Step 4. Remote access to the webcam of the WU-MRU. 5

6 To have a live view of the fish in the MRU click on the webcam icon indicated with the red arrow (Fig. 6). To open the webcam you need to login (Fig. 7): 1. Username: aquaexcel and 2. Password: a specific password from WU-AFI. In the webcam tool (Fig. 7) you can navigate through the MRU-room using the webcam with the PTZ Control tool indicated with the red arrow in Fig. 7. You can maximize the view with the button indicated with the green arrow (Fig. 7). The start image of the webcam might differ from the image shown in Fig. 7. It is not allowed to change any other settings of the webcam. Go back to normal view with one click on the webcam screen. During dark part of the photoperiod in the metabolic research room the webcam screen is dark. This is usually between 7.00 p.m. and 7.00 a.m. C.E.T. Close the webcam with the red x in the right upper corner of the host pc view (indicated by the black arrow in Fig.7). Figure 6. Desktop of the host PC (see Fig. 1). 6

Remote access to the sensor data of the WU-MRU To go to the sensor data of the WU-MRU press with the cursor on the MRU-data icon on the desk top (indicated with the green arrow Fig. 8). Figure 8. Desktop of the host PC. The green arrow indicates the button to be pressed to get access to the sensor data of the WU-MRU (see Fig. 1). Step 6. How to end a remote access session When you finish a remote session it is important to disconnect in a proper way from the host pc. If you do not disconnect properly it may not be possible to reconnect to the host pc again without intervention from people in Wageningen. If this happens contact Menno ter Veld and/or Ep Eding. In the sensor data program (Chapter 4. Viewing sensor data): 7

8 1. one can leave any sub-menu by pressing button 8 (EXIT) on the bottom of the screen (Fig. 9). 2. one can leave the main HTBasic menu by pressing the white cross in red block in the top right corner of the HTBasic menu pointed by the red button(fig. 9). You will return to the desktop of the remote connected host pc (Fig. 8). To stop the remote session press on the windows symbol in the bottom left corner of the screen indicated by the red arrow in Fig. 10. Then press on the white triangle behind the shutdown button to open a small menu (Fig. 10) and press on the Log off button indicated by the red arrow in Fig. 10. One should not press on the shutdown button because thereafter remote access is no longer possible until the host pc is manually turned on again. Finally one should stop the LogMeIn session by pressing the Disconnect button in the left side (LogMeIn) menu bar. Indicated by the blue arrow in Fig. 9.

Viewing sensor data (after remote access) When you press with the cursor the MRU-data icon on the desk top (indicated with the green arrow Fig. 8) the screen in Fig. 11 showing the main menu bar of the MRU will pop up. The main menu contains the following submenu s: 1. Show containers 2. Functions O 2-control (cannot be used by the remote user) 3. File functions (cannot be used by the remote user) Figure 11. Main menu of the WU-MRU: sub menus are (1) Show containers (metabolic chambers 1-12), (2) Functions O 2-control (3) File functions. 4.1 Show containers. Press on the show containers (= metabolic chambers 1-12) menu to get access to the next sub-menus (Fig. 12): 1. Sampling gas concentration (cannot be used by the remote user) 2. Sampling water data 3. Show plotted data Figure 12. Sub menu of how containers (metabolic chambers 1-12) menu:(1) Sampling gas concentrations, (2) Sampling water data, (3) Show plotted data. 9

10 4.1.1 Sampling gas concentration When opening the sub-menu: Sampling gas concentration one enters de actual measured sensor data of gas concentration sampling (Fig. 13). This are the results of gas concentrations measured above the water level in a metabolic chamber when experiments with air breathing fish are conducted. In the upper part the data of tanks that are actually measured is visible and in the lower part the last recorded data of all tanks is visible. This feature cannot be used with remote access. Figure 13. Menu of Measured gas concentration data Sampling water data When opening the sub-menu: Sampling water data one enters the actual measured sensor data of water sampling (Fig. 14). This are the results of ph, electric conductivity and oxygen concentrations in the water measured from the inlet and outlet of the metabolic chambers In the upper part the data of tanks (metabolic chambers 1-12) that are actually measured is visible and in the lower part the last recorded data of all tanks is visible. Figure 14. Menu of Sampling water data showing the actual sensor data of the WU-MRU. This are the results of ph, electric conductivity and oxygen concentrations in the water measured from the inlet and outlet of the metabolic chambers In the upper part the data of tanks (metabolic chambers 1-12) that are actually measured is visible and in the lower part the last recorded data of all tanks is visible. 10

11 4.1.3 Show plotted data. When opening the sub-menu Show plotted data (Fig. 12) the screen in Fig. 14 will pop up. On the bottom of the screen there are 5 different buttons: 1 Enter plotset; 2 Change set; 4 Save plotset; 5 Start plot and 8 Exit. Figure 15. Show plotted data menu to create plot sets. Per plot set the start of the measurements can be defined (e.g. 9 Apr 2013), the number of days on the X-axis (e.g. 2), the min. and max. value of the Y-axis for the curves 1-4, the logical channel numbers to be plotted ( a max. of four parameters per graph), the text for each plotted curve in the graph (e.g. O2-in (oxygen concentration going into each tank); O2-A10, O2-A11, O2-A12 (oxygen concentration in the effluent of metabolic chamber 10, 11 and 12). 1 Enter plotset: Within the program there is the possibility to save 50 different sets of plotted data. One can choose a plotset (four parameters at one time) by pressing on the Enter plotset button and type the number (between 1 and 50) of the desired plotset and confirm with the OK button. There are a number of plotsets prepared that should provide the graphical display of all the necessary measured values. In those cases one only needs to change the start date of a plotset and if necessary the minimum or maximum value of the Y axis. The next plotsets (No 1 15) are prepared and should not be changed except for the start date and value on Y axis (tank refers to metabolic chamber): 1. Oxygen concentration inlet and outlet tank 1,2 and Oxygen concentration inlet and outlet tank 4,5 and Oxygen concentration inlet and outlet tank 7,8 and Oxygen concentration inlet and outlet tank 10,11 and Water flow (l/min) in tank 1,2,3 and 4 6. Water flow (l/min) in tank 5,6,7 and 8 7. Water flow (l/min) in tank 9,10,11 and ph of inlet water and outlet tank 1,2 and ph of inlet water and outlet tank 4,5 and ph of inlet water and outlet tank 7,8 and ph of inlet water and outlet tank 10,11 and Electric conductivity of inlet water and outlet tank 1,2 and Electric conductivity of inlet water and outlet tank 4,5 and Electric conductivity of inlet water and outlet tank 7,8 and Electric conductivity of inlet water and outlet tank 10,11 and Change set: One can make a new plotset by changing the values of the different parameters. A Set of data contains 14 parameters: 1. Start date 2. Number of days on the X-axis 11

12 3. Minimum value of data on the left Y axis 4. Maximum value of data on the left Y axis 5. Minimum value of data on the right Y axis 6. Maximum value of data on the right Y axis 7. Logical channel number for curve 1 8. Logical channel number for curve 2 9. Logical channel number for curve Logical channel number for curve Text with curve Text with curve Text with curve Text with curve 4 The logical channel numbers represent a parameter from a certain position. In Table 1 you find the fixed combinations of parameter with logical channel number. Water meter Parameters water concentration Gas meter Parameters gas concentration Position ph EC po 2 CO 2 O 2 Inlet n.a n.a Tank Tank Tank Tank Tank Tank Tank Tank Tank Tank Tank Tank Extra 1* n.a n.a Extra 2* n.a n.a Table 1: Logical channel number for the different parameters and positions. * Positions Extra 1 and Extra 2 are two extra positions to measure water parameters in the inlet line. In case of gas concentration measurement those extra positions are used for calibration gas. To change a plot set one first needs to enter a plotset number between 16 and 50 as described above. Then press the change set button 2. In the pop-up box one enters the parameter number (1 14) that needs to be changed and confirms with the OK button. in the next pop-up box you enter the desired value of that parameter and confirm with the OK button. When you are finished with changing the parameters you enter parameter number 0 in the pop-up box, which means you are finished. After you have finished changing the parameters one should safe the plotset. 4 Save plotset: After finishing changing the parameters one should safe the plotset by pressing on the 4 th button on the bottom of the screen. Enter a number (16-50) for the plotset to be saved under, 1-15 are reserved for fixed plotsets please don t change those sets. 5 Start plot: After entering a plotset number one can press on the 5 button of the screen to go to the graphical presentation of the results in the selected plotset. In the graphical presentation screen there are also a number of buttons on the bottom of the screen which one can use to directly change the number of days on the x-axis and the value on the Y-axis without changing the setplot procedure as described under 2 Change set above. With the next and previous button one can scroll through the successive days on the x-axis. With the stop button one returns to the start screen of the Show plotted data menu. Er moet nog een data download procedure in!! Er moet een screen in met een voorbeeld van een grafiek. 12
