TruSense Configuration Manual TruSense Hardware Configuration 1 TruSense Hardware Configuration TruSense Hardware Configuration The TruSense system automates the collection of physiologic data from freely moving research animals via wireless telemetry. The system consists of a sophisticated acquisition and analysis software platform and a family of advanced, state of the art implantable telemetry transmitters. The communications link between these two components consists of wired and wireless components collectively referred to as the TruSense Hardware. Accessing TruSense Configuration from P3P
2 TruSense Hardware Configuration TruSense Configuration Manual From the menu bar click Hardware, and select Edit TruSense Configuration… This opens the TruSense Hardware Configuration window. If this is a new configuration, the red colored message text will inform you that you need to use Configure Sources… to define telemetry implant sources. Click on the Configure Sources… button to open the TruSense Wizard and begin the study configuration process.
TruSense Configuration Manual TruSense Hardware Configuration 3 TruSense Wizard The TruSense Wizard is a step by step guide which presents the user with a sequence of dialog boxes. This insures that the individual steps in the process are performed in correct order. There are seven pages in the configuration process. Page 1: Select CLCs for Study Page 1 of the TruSense Wizard is basic inventory. The Wizard queries the network; it finds all of the active CLCs (Com-Link Controller) on the system and lists them in the right hand column titled CLCs Currently on Network. To configure a CLC for use in the system, select a CLC and move it from the right column, CLCs Currently on Network to the left column, CLCs Selected for Study. Select a CLC in the right column, click and hold the selection with the left mouse button and drag the selection to the left column. Release the mouse button and the CLC will be added to the list.
4 TruSense Hardware Configuration TruSense Configuration Manual The newly added CLC will be added to the list with a circular status indicator. Green colored indicator: CLC enabled Red colored indicator : CLC disabled If the colored status indicator does not change from red to green, an error message will be displayed in the lower left corner of the screen.
TruSense Configuration Manual TruSense Hardware Configuration 5 At least one CLC must be selected and enabled (green indicator) before continuing. All of the “Selected” CLCs (left column) must be enabled before continuing. If everything is in order, you will be able to click the Next button to proceed to Page 2. If the Next button is not available, consult the error messages mentioned above. NOTE: At any time a CLC information pop up is available by hovering your mouse cursor over any of the CLC labels on the page. Page 2: Frequency Configuration Page 2 allows the user to select a separate frequency for each CLC. As many as four CLCs may be configured at one time, but each CLC must be assigned a unique operating frequency.
6 TruSense Hardware Configuration TruSense Configuration Manual Assign Unique CLC Frequency Frequencies to Scan Assign Unique CLC Frequency The CLCs that are enabled in the previous step are listed in the left hand column labeled Assign Unique CLC Frequency.
TruSense Configuration Manual TruSense Hardware Configuration 7 The left hand side of the page is arranged in a table. Assign Unique CLC Frequency CLC label Current CLC freq: Select freq. o CLC Label: The name that is assigned to the CLC o Current CLC freq: The currently assigned frequency o Select freq.: Drop-down with freq. options The current operating frequency of each CLC is listed in the center column. Use the drop-down menu to the right of the CLC to select an available communication frequency. The frequencies are designated by four alpha-numeric characters XX – YZ (XX = region, Y = freq, Z = group). Region Frequency Group F1 = USA A 1 F2 = Europe B 2 C D
8 TruSense Hardware Configuration TruSense Configuration Manual Guidelines for selecting frequencies The frequency Group designation (above) is used to allocate certain frequencies as Primary or Secondary. Group 1 (A1, B1, C1, D1) is the Primary frequency and Group 2 (A2, B2, C2, D2) is the Secondary frequency. When configuring multiple implants in adjoining cages, it is advisable to configure adjoining cages with alternating frequency Groups. Example cage 1-Primary group; cage 2-Secondary group; Cage 3-Primary and so on… Each CLC that the Wizard detects must be assigned a unique communication frequency. CLC frequencies must be unique and should be from the same frequency Group. o A1, B1, C1, D1 o A2, B2, C2, D2 The frequency options that are available to assign to CLCs are listed in the right hand column labeled Frequencies to Scan. The user must assign a unique frequency for each CLC before continuing to the next page. To assign a frequency, left-click the down arrow of the drop-down menu associated with each CLC listed.
TruSense Configuration Manual TruSense Hardware Configuration 9 Frequencies to Scan The TruSense system consists of CLCs, TRXs, and telemetry implants. The proprietary communication protocols use several different radio frequencies to communicate with the implants. All individual implants are assigned to a particular frequency. New implants that have not been previously configured will be detectable using the default frequency assigned during manufacturing. If you wish to re-configure an implant that has been altered from the default frequency (previously configured); that implant’s communication frequency will need to be included in the Frequencies to Scan dialog below. In the previous section, Assign Unique CLC Frequency, the user assigns a separate frequency to each CLC. In this section, the user selects which additional radio frequencies the system will scan in order to locate individual implants. If all of the implants are previously un-configured, the user must only insure that the default shipping frequency is assigned to a CLC in the left column – or is checked to be scanned in the right column. The frequencies are designated by four alpha-numeric characters XX – YZ (XX = region, Y = freq., Z = group) Region Frequency Group F1 = USA A 1 F2 = Europe B 2 C D The frequencies that are assigned to CLCs in the left column, Assign Unique CLC Frequency, will automatically be scanned for implants. Once a frequency is selected for a CLC, that frequency is no longer offered as an option in the Frequencies to Scan column. The Frequencies to Scan column is provided so that the user will be able to locate implants that have been previously assigned to other frequencies and allow them to be re-configured.
10 TruSense Hardware Configuration TruSense Configuration Manual The factory default frequencies for new implants are: o F1-B1 for USA o F2-B1 for EU The TruSense Wizard can configure eight implants per configuration cycle, therefore there should only be eight implants powered ON during this process. NOTE: Implants are shipped with a factory default frequency already assigned. If an implant has been subsequently configured with a non-default frequency it will not be located unless that altered frequency has been selected to be scanned. NOTE: If the frequency of a previously configured implant cannot be determined, the user may choose to scan all of the available frequencies. The scanning of all available frequencies will take extra time. Click the Next button to progress to the next page – Find All Implants Within Range.
TruSense Configuration Manual TruSense Hardware Configuration 11 Page 3: Find All Implants Within Range In this step of the configuration process the CLCs incrementally scan the frequencies selected in the previous screen. The “operational” telemetry implants, detectable in the network environment, will be listed in the left dialog box labeled Found Implants. The green progress bar tracks the status of the searching process and displays the frequency currently being scanned. NOTE: It is normal for this process to take several minutes. Transmitters that are power ON, communicating, and within range will be listed in the Found Implants column once they are identified. Transmitters that were previously configured in a study, but not yet detected by this iteration of the Wizard, will be listed on the right in the Implants Not Found column. Implants will move from right to left as they are detected. NOTE: Implants that are powered OFF will require a magnetic swipe in order to place them in a communication mode.
12 TruSense Hardware Configuration TruSense Configuration Manual NOTE: At any time, an implant information pop up is available by hovering the mouse cursor over the implant line item listed in a dialog box. Once the scanning process is complete and all of the implants are identified, the progress bar will be solid green and the message “Scanning Frequencies … Process Complete” will appear below the progress bar. Click NEXT to proceed to the next step – Assign Implants to CLCs. Page 4: Assign Implants to CLCs This stage of the process allows the user to custom configure the system to assign individual implants to specific CLCs: i.e. “I would like Implant A to be assigned to CLC #4, communicating on frequency F1-A1.” The implants that have already been assigned to CLCs will automatically be shown in the left column labeled CLC / Implant Assignment. The implants that have not been previously assigned to a CLC will appear in the right column labeled Found / Available Implants. To assign an available implant, click on the implant name in the right column and drag the implant into the box below the desired CLC on the left. Once all of the implants are assigned to the appropriate CLCs, Click Next.
TruSense Configuration Manual TruSense Hardware Configuration 13 Page 5: Warning of Pending Changes Page 5 is a confirmation page that warns the user that the pending changes are about to be committed. The Pending Changes are listed in the dialog box on the left. There is no user interaction in this step of the Wizard, it merely warns the user that once the Next button is pressed, there is no “Undo” option.  WARNING: Once the process is initiated, do not alter any components of the system.
14 TruSense Hardware Configuration TruSense Configuration Manual Click Next to progress to Page 6: Change Implant Frequencies. Page 6: Change Implant Frequencies Page six is the actual re-assignment process. One by one, the CLCs instruct the implants to switch frequencies and the implants comply. Once an implant switches to a new frequency, it can no longer communicate with its previously assigned CLC. The implant must then wait until a CLC on its new frequency attempts to contact it. The green progress bar shows the status of the re-assignment process and displays the pertinent information. NOTE: This process may take several minutes. As the re-assignments progress, the information in the text box below the CLC listing will continuously update. There is no overt confirmation that individual changes have occurred. Do not alter any components of the system until confirmation that the process is complete. Completion of the process is indicated by a completely green progress bar with the message “Process Complete” below.

A Hex value will also be reported in a table below the word Reply. Set RSSI Threshold RSSI stands for Received Signal Strength Indicator. It is a quantitative measure of the strength of the RF signal that the TRX is receiving from the implants. The Set RSSI Threshold command allows the user to adjust the lower limit of signal strength that the TRX will accept as viable information from the Implants. 1. Click on the drop-down menu labeled Implant ID: 2. Select a device by left clicking on an implant serial number. 3. Click on the drop-down menu labeled Implant Command. 4. Left click the Set RSSI Threshold command. 5. A small text-entry box will appear below the Implant Command: line. Allowable options for RSSI Threshold 0C 1C 6. Enter a new value for the RSSI Threshold and click the Send button 7. A blue colored banner with the word OK! will appear at the top of the screen.
TruSense Configuration Manual TruSense Hardware Configuration 51 8. Repeat the Get RSSI Threshold procedure for verification. Implant RSSI History Similar to the TRX RSSI History, the Implant RSSI History generates graphs in which the received signal strength from each of the TRXs is plotted for each implant. These graphs allow the user to track how well the implants are being received by each of the TRXs. In an actively running system these graphs continually update according to a user prescribed auto refresh rate. There will be one RSSI graph for each of the recognized implants in the system. Each implant will report the received signal strength from each of the TRXs it is communicating with. The RSSI graph will display one data set for each of the TRXs. To Set the Auto refresh rate of the graph, click on the drop-down menu at the top of the screen and select a new value.
52 TruSense Hardware Configuration TruSense Configuration Manual Glossary 1. CCA = Clear Channel Assessment - Clear channel assessment - The clear channel assessment operation determines whether the wireless medium is busy or idle. The MAC layer can then make a decision on whether to send a frame. 2. CLC = Communication Link Controller – processes telemetered data to/from the TRX for communications over the Ethernet connection. 3. Firmware = The combination of a hardware device and computer instructions and data that reside as read-only software on that device 4. IP Address = Internet Protocol address is a numerical label assigned to each device participating in a computer network that uses the Internet Protocol for communication 5. LBT = Listen Before Talk (LBT) or sometimes called Listen Before Transmit is a technique used in radio communications whereby a radio transmitter first senses its radio environment before it starts a transmission. 6. MAC Address = Media Access Control Address, is a unique identifier assigned to network interfaces for communications on the physical network segment. 7. NTP = Network Time Protocol is a protocol and software implementation for synchronizing the clocks of computer systems over packet-switched, variable-latency data network 8. RSSI = Received Signal Strength Indicator (or Indication): A signal or circuit that indicates the strength of the incoming (received) signal in a receiver. 9. TRX = Transceiver: Component that receives Radio-Frequency signals and converts it into digital form that is sent, via cable, to the Communication Link Controller; additionally, the component that transmits Radio-Frequency signals converted from digital form sent via cable, from the Communication Link Controller
