Appendices 473 Chapter 24 Licensed Functionality: Remote Monitoring Remote Monitoring functionality is available through an optional license available with AcqKnowledge 4.2 or above. The license must be authorized to access Remote Monitoring functionality. To add a license to an existing MP System, please contact BIOPAC. AcqKnowledge MP devices are generally tethered to specific computers where data acquisition is performed. In some laboratories, this computer may not be in the same location as the researcher performing the experiment. In MRI situations, for example, the data acquisition computer may be in the MRI control room but the researcher may be in a separate area. AcqKnowledge Remote Monitoring offers researchers the capability of checking on critical parameters from an alternate location. Remote Monitoring is a client/server application capable of locating and connecting to computers running AcqKnowledge on the same network. It consists of a simple browser interface, from which acquisitions can be started, stopped and remote data viewed during and post-acquisition. Remote Monitoring is supported in MP150 hardware only. About Remote Monitoring Remote Monitoring is licensed functionality and must be activated by BIOPAC. Remote Monitoring is for viewing of data only. Transformation and specialized analysis of graph data is not supported within the Remote Monitoring interface. The Remote Monitoring web interface consists of three primary pages: A list of open graph windows Configuration settings for an individual graph The data monitoring page. Remote Monitoring in AcqKnowledge Networking Preferences Remote Monitoring is enabled by default in AcqKnowledge Networking Preferences (Display > Preferences > Networking > Remote Monitoring). The Enable remote monitoring checkbox option activates the local machine on the network, making it visible to other local network machines also running AcqKnowledge Remote Monitoring. New! Remote Monitor Track the welfare of the subject with alarms to warn when signals fall out of range. The system will work on any device that has access to the same IP based network as the MP150. Simplified user interface to view subject data on another computer or mobile device bedside monitor display. The Webserver TCP port is the numerical port on which AcqKnowledge listens for remote requests. (This port is set to 8080 by default.) The Remote monitor URL is a clickable link that opens Remote Monitoring in the local machine s default web browser. This view will display acquisitions running on the local machine only. (This is actually an easy way to become familiar with Remote Monitoring). To view acquisitions running on machines in other network locations, the stand-alone Remote Monitoring Client application must be used. For further details, see the Remote Monitoring Client section on the following page. NOTE If a Remote Monitoring preference or port setting is changed, the new preference will not be applied until the subsequent AcqKnowledge application launch.
474 Remote Monitoring Client The Remote Monitoring Client is a stand-alone application residing in the AcqKnowledge program folder. This application facilitates the remote connection to other computers running AcqKnowledge acquisitions on the local network. AcqKnowledge does not need to be running on the local machine in order to use the Remote Monitoring Client to observe remote acquisitions in progress. To launch the Client, browse to the following directory: Main Drive:\Program Files\BIOPAC Systems, Inc\AcqKnowledge 4.2\RemoteMonitorClient.exe Double-click on the RemoteMonitorClient.exe to launch the application. After launching, the first presented item is the Remote Monitoring Server list. This is a list of other AcqKnowledge computers on the network that have Remote Monitoring enabled. Quit Refresh List Connect Exits Remote Monitoring Client Updates list of available AcqKnowledge Remote Monitor computers on network Connects to the computer selected in list The above-right figure shows a right-click contextual menu available within the Remote Monitoring Server List, which allows an alternate means of connecting to a selected computer. The Properties option displays the AcqKnowledge application status, along with network and hardware information about the selected computer. Remote Monitoring Client Browser Selecting a computer from the list launches the Remote Monitor Client browser interface. The navigation buttons operate in the same manner as most Internet browser controls. See the following page for details on the Remote Client browser buttons.

Quit exits the Remote Monitor. Edit contains a Copy option. (Copy function not supported in Windows version) Help displays About information for the current version of Remote Monitoring Client* In order for the Remote Monitor Client to properly display the server list of additional AcqKnowledge computers on the network, Bonjour Service for AcqKnowledge must be installed. (The option of installing Bonjour Service is presented during the licensed AcqKnowledge 4.2 application installation). If Bonjour is not installed, the following dialog will be presented upon launch of the Remote Monitoring Client:
476 The I.P. address of the desired computer can be entered into the http-address field. If the address is valid, clicking OK will connect the Remote Monitoring Client to this computer. An acceptable entry should include the server IP address and UDP port number. (Example; http://192.168.1.76:8080) Open Graphs Page When the Remote Monitoring Client browser is launched, a scrollable list of all graph windows currently open on the selected remote machine is presented. Only one graph may be selected at a time. Refresh this page Show Monitor Reloads the page and refreshes the list of available graphs. Advances the browser view to the selected file s setup page. Configuration Settings Page After selecting a graph and clicking Show Monitor, the following Monitor Setup page is displayed. This page contains configurable options for data display and other viewable parameters in the Remote Monitor graph. Note that all available options are set individually per channel. Visit the online support center at www.biopac.com

Serves the same function as the browser s back button. Saves the selected setup and advances the view to the data monitoring page. ( Show Monitor button at bottom of screen duplicates this link s function) Chooses the interval at which the monitored data is being refreshed over the network. The increments range from 1-sec. to 5 minutes. When enabled, an alarm will sound if the Remote Monitoring graph data display exceeds its maximum or minimum visible ranges. The audio sound is a onesecond beep followed by one second of silence. This audio playback is supported only on HTML5 compliant browsers. Displays assigned label of the AcqKnowledge data channel Displays a graphical plot of the currently monitored data. If checked, the most recent value of the channel data is displayed in a large font. If unchecked, textual display of this value is omitted. Displays minimum and maximum value of currently monitored data. If the channel value exceeds the current trend display range, the alarm changes the color of the textual display to red and optionally plays audio. Sets number of decimal places following channel display values. Data Monitoring Page After the desired channel setup parameters are selected, choosing Show Monitor will advance the view to the data monitoring page. If an AcqKnowledge acquisition is already in progress and data being plotted, the screen will appear similarly to above, with the graph plot tracing at intervals determined by the Monitor setup auto-refresh rate. If the acquisition has not been started prior to launching Remote Monitoring; the Start button will be displayed in this screen. (Remote acquisitions can be easily started or stopped from within this data monitoring page).
