HARDWARE DETAILSReceiver Maintenance and CareGuide to the SRX 600 receiver Rev A #10112 Chapter 1 - - Page 12 1HARDWARE DETAILS1RECEIVER MAINTENANCE AND CAREThe SRX 600 must be protected from excessive dust and moisture. If basic cleaning is required, the housing and front panel can be cleaned using a soft cloth. For a deeper clean, wipe the housing with a soft, damp cloth using a mild solution of soap and water. Do not allow any liquid to get inside the housing. When not in use, the unit should be stored in a cool dry place. FRONT PANEL COMPONENTS• A power On/Off and volume control knob (labeled OFF/VOL)• A 16-key pad and 2-line by 24-character LCD display • A standard 1/4 inch headphone jack (labeled Headphone)• A jack for connecting the power cable (labeled CHG)• Two LEDs labeled B and F• A BNC jack for connecting an antenna (labeled ANT)• A speaker for the broadcast of detections TURNING ON THE RECEIVERTurn the OFF/VOL knob clockwise until a click is felt. TURNING UP THE VOLUME ON THE RECEIVERTo turn up the volume, turn the OFF/VOL knob clockwise.

. . . . .HARDWARE DETAILSFront Panel ComponentsGuide to the SRX 600 receiver Rev A #10112 Chapter 1 - - Page 13 POWERING THE RECEIVER USING THE INTERNAL BATTERYThe receiver can operate continuously for up to 12 hours (light on) or 16 hours (light off) on its own battery supply, assuming it was fully charged to start. When the batteries need recharging this symbol appears in the lower right hand corner of the LCD display: .CHARGING THE INTERNAL BATTERYPlug the charger supplied with the receiver into the connection labeled CHG. Plug the other end into an outlet supplying 120V of AC power. When the receiver is fast-charging the LED labeled F on the front panel (LED to the right of the CHG jack) glows red. When the receiver is fully charged the LED labeled F (LED to the right of the CHG jack) glows green. The receiver takes approximately 8 hours to fully charge from a discharged state, as long as the charger that is supplied with the SRX 600 is used. It is not recommended to use any other charger than the one supplied. Use of other chargers could potentially reduce the effectiveness or damage the receiver.Every charger supplied by Lotek Wireless Inc. complies with UL and CSA national standards. MAINTENANCE AND CARE OF THE INTERNAL BATTERYIf the receiver is to be stored for extended periods (e.g. over winter) it is recommended that the battery be charged every three months.If the receiver is stored for an extended period of time without charging, performing a few (1 to 3) charge-discharge cycles often restores the main battery to a usable condition. Batteries are replaceable by Lotek Wireless Inc.

HARDWARE DETAILSBack Panel ComponentsGuide to the SRX 600 receiver Rev A #10112 Chapter 1 - - Page 14 1BACK PANEL COMPONENTS• USB cable connection• Two serial cable connections (Serial I and Serial II)• The receiver’s serial number• GPS antenna connection• UUC power cable connection• DC power DIN jack• ASP-8 cable connectionThe Serial I connection is provided for connecting the receiver to a computer or a modem. POWERING THE RECEIVER USING AN EXTERNAL BATTERYThe SRX 600 can operate from a regulated 11-16V DC power source, either an automobile or marine battery. Using a DC power source disables the receiver’s internal battery as long as the DC voltage being supplied is above 10 volts. Voltage associated with unregualted power supplies, such as a solar power, can exceed 16V and potentially damage the receiver. Ensure that any solar power sources used include a 12V regulator.If the supply voltage from an external battery goes below 10V or the power cable is not properly connected, the LED on the front panel labeled B turns off (LED to the left of the CHG jack) and the receiver uses the internal battery as long as it is charged enough to operate the receiver.The receiver internal battery cannot be charged from an external battery.Plug the power cable, supplied by Lotek Wireless Inc., into the receiver’s DIN jack on the back panel. Attach the other end to an automotive or marine battery. The LED labeled B on the front panel glows red (LED to the left of the CHG jack). This confirms that the receiver is now using the external battery for power.

. . . . .HARDWARE DETAILSTypes of TransmittersGuide to the SRX 600 receiver Rev A #10112 Chapter 1 - - Page 15 TYPES OF TRANSMITTERSA transmitter is a device that uses a series of single frequency pulses to communicate with the SRX 600 receiver. Lotek radio transmitters operate over a frequency range of 140 to 174 MHz. Lotek acoustic transmitters operate at either 66 or 77 kHz.There are three main types of transmitters:• Coded ID Only Transmitters: identified by a group of four pulses separated by specific amounts of time, which the receiver interprets to form the ID of that transmitter.• Coded Sensor Transmitters: identified by a group of four pulses that can vary the amount of time between each pulse to convey sensor information (e.g. temperature, pressure). • Beeper Transmitters: identified as a single frequency pulse that is typically used in large animal studies. They are used to establish an approximate location of a collared animal, within a kilometer or so.

THE KEYPAD AND LCD DISPLAYKeypad and Display StructureGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 16 2THE KEYPAD AND LCD DISPLAY2KEYPAD AND DISPLAY STRUCTUREThe keypad and LCD display define the interface through which the receiver is programmed. The program is designed like a hierarchy. All aspects of the program are accessed through keys on the keypad. Keys labelled Setup, Log On, Info, Manual, Codelog and Set Delta provide access to menus (note that in most cases there are also sub-menus). Three of these keys are referred to as modes: Setup, Manual and Codelog. Through these modes, specific aspects of the receiver’s functionality can be enabled, disabled or amended. The keypad is used to enter or select operating parameters, input data and for navigate through menus and pages. Every key, except Light, has two functions. Which function is accessible depends on the state of the receiver.The LCD display is a two line display that is used to request input, either in the form of a menu selection or the entry of a numeric value. It is necessary to spread out the information, therefore the display shows what is referred to as a page, whereby a menu item can link to more than one page. Scroll through pages using the right and left arrow keys or the END/ESC key. The LCD display also provides current setting information. This information depends on whether the receiver is Online or Offline. • If the receiver is Online then the display shows current settings within brackets after the title of a page (e.g. Scan Options) and still allows a new value to be entered. • If the receiver is Offline then the display shows current settings after the title of a page, but there is no provision for a new value to be entered.

. . . . .THE KEYPAD AND LCD DISPLAYLogging on to the receiverGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 17 LOGGING ON TO THE RECEIVERLogging on to the receiver provides the ability to change the state of the receiver. When a log on password is provided the receiver is considered Online. If no password is provided (logged off) then the receiver is Offline. The differences between Online and Offline are described below:• Offline: the receiver allows only read access, which means that most inputs are not allowed unless a log on password is provided. The only input allowed is the Reset Password function. • Online: the receiver allows full write access, which means that all functionality and input capability are available.Log on to the receiver via Log On > 1)Log On or Log On > 2)Log On via Factory Password. Wait a few seconds for the changes to be accepted and then the receiver returns to the last state that was active (e.g. scan) or the start page.The log on password is always 123456 unless it is changed via Setup > 3)Change Password. Logging on via the factory password provides the ability to log on quickly, as long as the factory password (123456) is being used. This feature is convenient for people who do not need or want to have a specific confidential password.Logging on can be done at any time during the operation if the receiver, except while using the Info key and its menu items. LOGGING OFF Logging off can be done at any time during the operation of the receiver, which means that data collection can continue while limiting access to settings via a password. Logging off means the receiver is Offline.Log off from the receiver via Log On > 2)Log Off or Log On > 3)Temporarily Log Off. Wait a few seconds for the changes to be accepted and then the receiver returns to the start page (first information shown after receiver turns on).Temporarily logging off creates a restriction, whereby logging on is only accessible from the keypad and no longer accessible from the SRX Host software, except via the Host’s Keypad Simulator.

THE KEYPAD AND LCD DISPLAYChanging a log on passwordGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 18 2CHANGING A LOG ON PASSWORDAccess to this feature is only provided in Setup Mode. A password can be changed as long as the receiver is Online. Changing the password requires that the old password be entered followed by the new one. The receiver automatically places a slash [/] between the two passwords as they are entered. The password must be made up of 6 numbers.Change the password via Setup > 3)Change Password.RESETTING A LOG ON PASSWORDAccess to this feature is only provided in Setup Mode. A password can only be reset if the receiver is Offline.Resetting the password is not normally used, except to provide a recovery mechanism if the current password has been lost or forgotten. In such an event, Lotek support staff can take information about the receiver’s serial number and the six digit number associated with the Reset Password function and provide a password that can be used to log on to the receiver. Go to Setup > 3)Reset Password to reset the password.

. . . . .THE KEYPAD AND LCD DISPLAYUsing the input keysGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 19 USING THE INPUT KEYSENTER Once a value is entered for an input, pressing the Enter key causes the receiver to accept that input and save it (as long as the receiver is Online).END/ESC The END/ESC key is used for navigation and cancelling the effect of an input. For navigation it provides the ability to “go back” to the last menu that was accessed. For example, after enabling TOA, press END/ESC to go back to the Scan Options menu (where the TOA feature was accessed).Cancelling the effect of an input takes on two forms:• Cancelling an input before it is completely entered (e.g, while entering 148.08_). Many inputs are automatically accepted as soon as the number is fully entered. If a number is only partially entered and it is realized that the input is not desired, then press the END/ESC key to cancel.• If the receiver is Online then the END/ESC key is used to stop a current active state of the receiver (e.g. GPS position acquisition or a Scan Cycle). This action is dependant on the status of the receiver. For example, if the receiver is not trying to acquire a GPS position, then the END/ESC key has no effect. If the receiver is Offline then the END/ESC key has no effect.NUMBERSAny of the keys that have a number (0 through 9) in their lower portion are used in two ways: to select a menu item or to enter in values for an input. In the first case, all menu items available have a number in front of them (e.g. 1) Gain). In order to select a menu item, press the corresponding number on the keypad (e.g. press 1 to go to the Gain menu). In the second case, for example, when prompted to enter a value for gain, use the keypad numbers to enter the desired value.

THE KEYPAD AND LCD DISPLAYUsing the input keysGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 20 2DECIMALThe lower portion of this key provides the decimal point needed for many input values.PLUS / MINUS SIGNPlus (+) or minus (-) signs are provided at the beginning of an input prompt (e.g. >+). Minus signs are necessary when entering the GMT correction into the receiver.To change a sign press the +/- key once.

. . . . .THE KEYPAD AND LCD DISPLAYUsing the navigation keysGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 21 USING THE NAVIGATION KEYSRIGHT ARROW AND LEFT ARROWThe Right and Left Arrow keys are used for navigating forwards and backwards through pages. If more than one page is available a “-->” or “<--“ symbol appears in the lower right corner of the LCD display. Multiple pages are used to accommodate the limitations of a two-line display, so any menu items or inputs that exceed this space must be spread out. For example, in order to see all of the menu options from the Search page in Manual mode, use the right arrow to scroll through the next two pages of menu options. The only time an arrow prompt in the lower right corner is not provided is when the receiver’s battery is low. In this case a small square icon is provided indicating low battery status.BSPACEBackspace erases the value of an input one number/value at a time. This is similar to using the backspace key on a computer keyboard.

THE KEYPAD AND LCD DISPLAYUsing the Info keyGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 22 2USING THE INFO KEYThe Info key provides access to the following:• Battery voltage (main and backup) [1)Bat]• Available memory (in Kilobytes) [2)Mem]• Start frequency, Intermediate Filter Frequency (I.F.) and Local Oscillator Frequency (L.O.) [3)Freq]• Version numbers of the Boot Code, Master and Slave [4)Ver]• Configuration settings (Scan Time and Code Set) [5)Cfg]• Service information (the receiver’s Serial Number and the number of hours that the receiver has been in operation since its last service) [6)Service]• The factory password (123456) [7)Factory Password]• Ability to answer an incoming call via the Modem [8)Answer Incoming Call]The backup battery is 3.3V at full capacity. If this value should drop to 2.8V or less, the receiver should be returned for service. Regardless of the status of the battery, the receiver should be serviced every two years.Start frequency, I.F. and L.O. are only used by Lotek Wireless Inc. for manufac-turing purposes.When accessing the Info key menu items it is not possible log on to the receiver; these features are mutually exclusive. ANSWERING AN INCOMING CALLThis feature is provided for testing and troubleshooting purposes. When a modem is being used to access the receiver it rings when a call is made. The receiver is programmed to automatically answer all calls made. If the receiver does not answer after the modem rings 4 or more times there may be a problem with the auto-answer feature.However, the call can still be answered via Info > 8)Answer Incoming Call.

. . . . .THE KEYPAD AND LCD DISPLAYAdjusting Frequency and GainGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 23 ADJUSTING FREQUENCY AND GAINA new frequency can be selected using the Up or Down Arrows. The amount of increment or decrement is specified by Set Delta for frequency (see section called Set Delta for details).A new gain can be selected using the Up or Down Arrows. The amount of increment or decrement is specified by Set Delta for gain (see section called Set Delta for details).USING NOISE BLANKING (N BLANK)Noise blanking enhances the receiver’s audio performance, especially in aircraft or other high-noise environments, by suppressing the receiver’s audio response except when a signal is detected. This also helps prevent auditory fatigue when using the receiver for extended periods of time.Press the key labelled NBlank to enable and disable noise blanking.TURNING ON THE BACKLIGHTPress the Light key once to turn on the backlight. Using the light consumes more power, but may be necessary in low light conditions to see the LCD display.SET DELTA Set Delta is used to set the increments for frequency and gain so that when the Up and Down Arrows for frequency and gain adjustment are used, the receiver knows the amount it should advance up or down.

THE KEYPAD AND LCD DISPLAYGPSGuide to the SRX 600 receiver Rev A #10112 Chapter 2 - - Page 24 2SET DELTA FOR FREQUENCYWhen incrementing frequency manually the receiver adds the Set Delta frequency increment to the frequency being used at the time the frequency is adjusted up or down. Increments are in kHz.Set this increment via Set Delta > 1)Freq.SET DELTA FOR GAINWhen incrementing gain manually the receiver adds the Set Delta gain increment to the gain being used at the time the gain is adjusted up or down.Set this increment via Set Delta > 2)Gain.GPSThe GPS key provides the ability to acquire a GPS fix. This data is not stored by the receiver (except if accessed in Codelog mode). It is recommended that this feature be tested before the GPS feature is enabled (see chapter Codelog Mode, section Enabling/Disabling GPS Positioning) and a scan started via Codelog Mode. Testing the feature ensures that the receiver is able to take a valid 2D position. When testing, ensure that the GPS antenna supplied with the receiver is connected to the receiver and that the antenna has a clear view to the sky.CRTO cannot be used with the GPS 2D positioning feature of the receiver; however it still allows the GPS clock to function.STARTING A GPS ACQUISITIONStart acquiring a GPS 2D position by pressing the GPS key on the keypad (key number 4). While attempting to acquire a position, the display shows the number of satellites as they are found.If a valid position is acquired the following information is provided on the display: Latitude, Longitude, current date, current GMT time, the number of satellites used, HDOP and PDOP. The display flips back and forth between showing the Latitude and Longitude for 4 seconds and the satellites, HDOP and

Either the time or date are also shown on the display and are updated every 5 seconds.GPS cannot be used if the receiver is logged off. However, it is possible to log off from the receiver while the receiver is attempting to acquire a GPS position. When logging back on, the display shows the results of the GPS position.STOPPING A GPS ACQUISITIONPress the END/ESC key to stop acquiring a GPS position.

SETUP MODEChapter OverviewGuide to the SRX 600 receiver Rev A #10112 Chapter 3 - - Page 26 3SETUP MODE3CHAPTER OVERVIEWSetup Mode allows global settings to be changed and applied. Global settings are those settings that affect how the receiver operates. Setup Mode features include:•Configure communication settings (serial and modem)• Set communication settings to the default Factory Settings •Enter the Local Date, Time and GMT correction• Reset or change the log on PasswordAfter the Setup key is pressed the main menu items are as follows: 1)Comm, 2)Time, 3)Reset/Change Password. This section is organized by these three menu items.1)COMMCONFIGURING SERIAL PORT SETTINGSThere are two serial ports available on the backpanel of the receiver: Serial I and Serial II.Each serial port must have baud rate (for modem), parity, data bits and stop bits defined. If these settings are not changed then the default values are used, which are: baud rate=115200, parity=No, data bits=8 and stop bits=1.The path to define each of these parameters is summarized below:• Baud Rate: Setup > 1)Comm > 1)Configure > 1)Serial I or 2)Serial II > 1)Baud Rate. Select one of the nine different baud rates.

. . . . .SETUP MODE1)CommGuide to the SRX 600 receiver Rev A #10112 Chapter 3 - - Page 27 • Parity: Setup > 1)Comm > 1)Configure > 1)Serial I or 2)Serial II > 2)Parity. Select to have no parity, odd parity or even parity.• Data Bits: Setup > 1)Comm > 1)Configure > 1)Serial I or 2)Serial II > 3)Data Bits. Select either 7 or 8 data bits.• Stop Bits: Setup > 1)Comm > 1)Configure > 1)Serial I or 2)Serial II > 4)Stop Bits. Select either 1 or 2 stop bits.The receiver also needs to know if serial I is going to be used for connection with a modem (see Configuring Modem Settings for details). CONFIGURING MODEM SETTINGSThe modem must be connected to serial I. Serial I must have the appropriate baud rate so that it is compatible with the speed of the modem and it is highly recommended that the port baud rate be set at or below the actual throughput of the line, to avoid overloading the modem’s internal buffers.For example, if the modem is capable of communicating with the receiver at 115200 baud, but the actual telephone line speed is on the order of 57600, the serial I setting should not exceed 57600.Access modem settings via Setup > 1)Comm > 1)Configure > 1)Serial I > 5)Modem.There are three actions associated with the modem: assign Serial I to the modem, view the CMDS for the modem and initialize the modem.

As soon as a modem is connected to the receiver and the receiver is Online, the CMDS parameters are sent to the modem. If no modem is connected the following message is provided, “No Modem, please select it via Setup/Comm”.If the modem’s CMDS parameters are edited via the SRX Host while the modem is connected then the modem cannot function properly. There are two ways to correct for this: initialize the modem or unplug the modem and then plug it back into the receiver. In the case of the latter, as soon as the modem is again connected to the receiver, the receiver sends the new CMDS to the modem (like a refresh).Initialize the modem via Setup > 1)Comm > 1)Configure > 1)Serial I > 5)Modem > 3)Initialize.

During manual mode data is not recorded by the receiver. Detections are indicated by pings or clicks that can be heard from the speaker on the front panel of the receiver. Adjust the volume by turning the OFF/VOL knob clockwise. For listening to weak signals or working in environments with a lot of ambient noise, use a pair of good quality isolating (monaural) headphones.Some of the receiver’s settings can be changed while in manual mode. After selecting the Manual key on the keypad, three menu items become available: 1) Code Set, 2)Search and 3)Signal. The first menu item, Code Set, provides the ability to change the active code set. After selecting 1)Code Set, use the keypad to select the desired code set. The other two menu items, Search and Signal, provide two different methods of starting a scan in manual mode and changing various settings that affect the scan.There are several settings that are the same in either Search or Signal. These are as follows:• Start a scan • Setting the type of transmitter to scan (Beep/ID/Sensor)• Change the Set Delta frequency and/or gain • Acquire a GPS 2D position • Enter a gain• Set the noise threshold

A pulse interval is the period of time that elapses between one pulse to the next. The three pulse intervals are unique to every transmitter so that the receiver can identify the transmitter.In order for the receiver to interpret the pulse intervals it must reference a library, which is called the Code Set. The code set used with the receiver specifies all the different combinations of pulse intervals that can exist, as well as gives the receiver information on how to interpret tags that transmit sensor data within that code set. The receiver is configured with the required code set(s) for a study at the time of manufacture. Current code sets are Lotek 1, Lotek 2, Lotek 3, Lotek 4 and Lotek 5. The code set must be selected before data collection can proceed.Lotek Code Sets and Firmware1 (“FIRMWARE”) are protected by copyright laws and international treaty provisions.

MANUAL MODE2)SearchGuide to the SRX 600 receiver Rev A #10112 Chapter 4 - - Page 34 42)SEARCHSTARTING A SCAN VIA SEARCHA scan cycle can be started via Manual > 2)Search > 1)Start. To stop a scan, press the END/ESC key.Starting a scan from the Search menu means that the receiver scans through a range of frequencies looking for a signal, using the Frequency Step setting. The frequency step is the increment in kHz that the receiver uses to increase the frequency as a scan proceeds.The frequency range is defined by entering a Maximum Frequency and a Minimum Frequency. After a scan is started the receiver begins scanning the minimum frequency and then increments the frequency according to the frequency step until the maximum frequency is reached.While scanning, the LCD display provides information on the current frequency and antenna being scanned. After a valid detection is made the display also provides the transmitter’s ID and the time, type of transmitter and signal strength.If a valid detection is made on any frequency during the scan the receiver continues scanning the frequencies for that transmitter until it finds a local maximum for that frequency, at which point it stops scanning and displays the maximum signal strength and the frequency at which it was found. The local maximum is the frequency at which the signal strength is highest for a given transmitter.Once a scan is stopped there are four choices: exit Search, edit settings, pause the scan or resume scanning.SELECTING A CODE SETCodes Sets are accessed via Manual > 2)Search > 1)Start > 1)Code Set.

This function suspends the scan cycle on the frequency and antenna that was being scanned before pause was selected. This also means that the receiver does not change the frequency or antenna it was scanning when pause was selected, but it does continue logging data for that frequency and antenna. RESUMING A SCANUpon resuming a scan (Manual > 2)Search > 1)Start > 0)Resume Scan), the receiver uses the last settings applied during the pause, thereby replacing the previous values in the active configuration.SETTING THE TYPE OF TRANSMITTER TO SCANVia Search go to Manual > 2)Search > 1)Start > 2) Show Beep/ID/Sensor.The type selected depends on the type that was selected before using this feature.

Data collected using a configuration is saved to the receiver’s flash memory.Up to 8 configurations can be created using the SRX Host and then sent to the receiver. All configurations are sent in a single file even if all 8 are not used. Once the receiver has a configuration loaded into it, it can be selected and used. This is referred to as the active configuration. When a scan cycle is started via Codelog mode, the receiver uses the active configuration to apply the desired settings.It is recommended that all settings for a configuration be initially set using the SRX Host software and then added to or amended through the receiver’s keypad.Certain settings cannot be edited in the active configuration after data has been collected, because this data exists in the receiver’s flash memory and references a frequency table and its specific channel assignments. Therefore, the receiver does not allow entries in an existing frequency table to be changed if there is data in the receiver’s memory. If any changes need to be made to existing references, the data in the receiver must first be downloaded and then erased from the receiver’s memory (via Codelog > 2)Scan > 2)Del all data).The exception to the statement above is that a new frequency can be added to the frequency table and it is also possible to remove a frequency from a frequency table.

The amount of time a scan cycle lasts depends on the number of frequencies and antennas/hydrophones, the scan time and Total Scan Time. It also depends on two additional features: Time-Out on Acquisition (TOA) and Master Antenna Preview. Frequencies and antennas (radio antennas and hydrophones) are scanned in the order they are entered into the receiver. This is referred to as the Scan Order. The only conditions that can terminate a scan cycle are stopping data collection, battery failure or if all available memory is filled to capacity.The total scan time is the maximum amount of time a complete scan cycle can take, but the actual time to complete a scan cycle can be less than this, since other settings, like TOA, may cause the receiver to adjust the scan time adaptively. If a scan cycle takes less than the calculated total scan time calculated then the receiver can be setup to wait until the total scan time has elapsed before it starts another scan cycle. Setting the total scan time allows multiple receivers to synchronize their scan cycles and it is a power saving option, because the receiver shuts down all antennas and lowers their gain while it waits for the total scan time to elapse.Any time the receiver is not actively scanning it shuts down all antennas and lowers their gain to save power. SELECTING A CODE SETA transmitter code is made up of four pulses that define three pulse intervals. The time between repetitions of the code is called the Burst Interval. A pulse interval is the period of time that elapses between two consecutive pulses in a code. Every transmitter is assigned a unique code so that it, and any sensor data associated with it, can be identified by the receiver.In order for the receiver to interpret the pulse interval sequence it must reference a library, which is called the code set. The code set used with the receiver specifies

CODELOG MODE1)Config## > 2)Scan SettingsGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 48 5all the different combinations of pulse intervals that can exist, and gives the receiver information on how to interpret transmitters that transmit sensor data using that code set. The receiver is configured with the required code set(s) for the study specified at the time of purchase. Current code sets are Lotek 1, Lotek 2, Lotek 3, Lotek 4 and Lotek 5. The code set must be selected before data collection can proceed.Lotek Code Sets and Firmware1 (“FIRMWARE”) are protected by copyright laws and international treaty provisions.

This is referred to as the scan time. Scan times are typically set to the maximum transmitter burst interval plus 0.5 seconds.Scan time can be set with a resolution of 100ms. The range is 0.1s through 99.9 seconds.Set the scan time via Codelog > 1)Config## > 2)Scan Settings > 2)Param > 2)Scan Time. Scan time format is in seconds.

Use the results of this calculation for the Total Scan Time value.(# of Radio Frequencies) x (# of Radio Antennas [including Master])+(# of Acoustic Frequencies) x (# of Hydrophones [including Master])=Total Number of Scan CyclesxScan Time (e.g. 15 seconds)=To t a l S c a n Ti m e

With TOA enabled the receiver monitors each frequency+antenna combination until the first valid detection, thus shortening the total scan time. TOA may therefore be used to minimize the amount of time it takes for the receiver to scan all of the available frequencies and antennas. This is not always a desirable result since it can also result in lost data by ending a scan time before other transmitters in the area can be detected on that frequency and antenna combination.Consider the following example: TOA is enabled, the scan time is set to 20 seconds and the receiver gets a valid detection after 6 seconds. The receiver is monitoring frequency A and antenna E when it gets the detection. Immediately after the detection the receiver stops scanning frequency A and antenna E and moves on to the next frequency+antenna (depending on the scan priority that was selected). TOA can be enabled in conjunction with other settings like Frequency Priority, Antenna Priority and Master Antenna Preview.If TOA is disabled, the SRX 600 scans each frequency+antenna combination for exactly the specified scan time before switching to the next frequency+antenna combination.ENABLING/DISABLING CRTOThe Continuous Record Time Out (CRTO) is used to save memory space. CRTO gives the receiver the ability to track the number of valid detections for each transmitter ID in combination with a specific frequency and antenna over a fixed period of time (CRTO Window). The CRTO Window is defined by the CRTO Timeout.When the CRTO Window expires, the receiver stores a single record for every transmitter that was received in the following format: Transmitter X on Frequency A and Antenna E was detected N times with an average Signal

This allows the resulting data record to be stamped with the arrival time of the first valid detection.• When the CRTO Window elapses the time of the first valid detection is recorded along with duration information, which refers to the total amount of time between the first and last detections for each transmitter+frequency+antenna combination.• If a transmitter+frequency+antenna combination is detected several times during the CRTO time period then the exact time of every detection for that transmitter is not recorded • It is not possible to determine if the valid detections were evenly distributed or grouped together during the CRTO windowIf CRTO is enabled then Automatic Gain Control (AGC) is immediately disabled, because gain must be fixed for the duration of a data record.If CRTO is enabled then the GPS 2D positioning feature of the receiver is disabled; however it still allows the GPS clock to function.SETTING THE CRTO TIMEOUTThe CRTO Timeout specifies the amount of time the CRTO Window is open for. The longer the timeout, the fewer records there are per transmitter detected.For example, a CRTO Timeout of 1 minute for a Scan Cycle that has been scanning for two minutes yields only two data records for each transmitter that is detected over that two minute period. This is because all detections during the timeout period (CRTO Window) are compressed into one record when the timeout expires.If the CRTO Timeout for the example above was increased to 4 minutes then there would only be one record after two minute period. This demonstrates the impact of a longer CRTO Timeout.The timeout can be set from 1 minute up to 99 minutes.

This feature is particularly useful when there is sporadic external noise, like turbines coming on once a day at a hydro dam. In cases like these the receiver can automatically adjust the gain when these noise events occur and then return the gain to its original set value when the noise event is over.CRTO cannot be used if AGC is enabled, because gain must be fixed for the duration of a data record.ENABLING/DISABLING THE GPS CLOCKWhen the receiver begins scanning it can simultaneously update the GPS clock as long as the GPS clock is enabled. This provides a higher time resolution for data recorded by the receiver.When the GPS clock is enabled it comes on for five minutes and updates the clock every 1 second and then it turns off for three hours. It repeats this cycle continuously until scanning is stopped. During a scan the display flashes the letter G to indicate that the GPS clock is enabled.If the GPS clock is disabled the GPS positioning feature is automatically disabled.Enable/disable the GPS clock via CodeLog > 1)Config## > 2)Scan Settings > 3)Options > 4)GPS > 1)En/Dis GPS Clk.

There are several parameters related to frequency that need to be set before data collection can begin. These are described in the following.CREATING A CONFIGURATION SPECIFIC FREQUENCY TABLEA Configuration Specific Frequency Table is a group of frequencies that are assigned to a specific configuration. When a scan cycle is started the receiver scans the frequencies in the table in the order they were entered. From this point forward in the manual Configuration Specific Frequency Tables are referred to as just frequency tables.A configuration contains information about all settings that the receiver uses to perform a scan. Up to 8 Configurations can be created and stored in the receiver. Configurations can be initially created using ONLY the SRX Host software and then sent to the receiver. Any/all configurations created are sent to the receiver in one file.There are several points to review about frequency tables:• Up to 8 frequency tables can be created (one for each configuration)• A single frequency table can contain up to 128 frequencies • Frequency tables can be made up of radio and/or acoustic frequencies in any order• A frequency table is not active until a configuration using that frequency table is selected• All frequencies in all frequency tables are also copied into the master frequency table MASTER FREQUENCY TABLEAll Frequencies entered into the receiver are also copied into a master frequency table. Up to 128 distinct frequencies can be copied into the master table, however

ADDING A FREQUENCY/CHANNEL Enter a frequency into the receiver via Codelog > 1)Config## > 3)Freq/CH > 1)Add > 1)Radio or 2)Acoustic. The display first prompts for the frequency to be entered. The decimal point is not automatically provided; use the decimal key. After the full frequency value has been entered, the display automatically goes to the Set Ch# (set channel number) page. Enter a number for the channel that will be assigned to the frequency entered. After entering a channel number, press the ENTER key to apply the changes. COntinue to add frequencies+channels in this manner.Frequencies cannot be changed through the keypad after they are added; they can only be deleted or disabled.No two Frequencies have the same channel number. Assigning a channel number provides an easier way of referencing frequencies. For example, it is easier to say “scan channel 3” than it is to say “scan frequency 151.360”.DELETING A FREQUENCY/CHANNELIt is important to note that because frequencies in a frequency table are also copied into the master table, they can be deleted from a frequency table and still exist in the master table.A frequency can be deleted from a frequency table via Codelog > 1)Config## > 3)Freq/CH > 2)View/Modify > 1)Del. ENABLING AND DISABLING A FREQUENCY/CHANNELIndividual frequencies in a frequency table can be enabled (available for scanning) or disabled (skipped), whereby during a scan a frequency can be temporarily removed from the scan cycle until it is needed again. The receiver only scans frequencies that are enabled. By default all frequencies entered are considered enabled.

CODELOG MODE1)Config## > 3)Freq/ChGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 56 5For example, if a transmitter that uses frequency 148.360 is intentionally removed from the reception area for a period of time, there is no point in using the receiver to scan that frequency. In this case the frequency can be disabled or skipped.A frequency can be enabled or disabled via Codelog > 1)Config## > 3)Freq/CH > 2)View/Modify > 2)En/Dis. The display provides the only indication that the frequency is enabled or disabled by showing EN or DIS after the frequency selected.ASSIGNING A TRANSMITTER TYPE TO A FREQ/CHThe receiver defaults to the ID only type for new frequency+channel assignments; others must be specifically assigned.Assign a transmitter type to a frequency+channel via Codelog > 1)Config## > 3)Freq/CH > 2)View/Modify > 3)ID/Sen.

CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 58 51)CONFIG## > 4)ANT/HYDRAntennas pick up signals from transmitters and delivers them to the SRX 600 receiver. A typical configuration of the SRX 600 system can accommodate up to eight antennas, which can be monitored one at a time or simultaneously. Antenna inputs accept signals from radio antennas and upconverted acoustic sources (hydrophones). To use more than one antenna the ASP-8 switchbox is needed. Connections to the ASP-8 are referred to as Antenna Ports and are associated with specific Port Numbers. A single antenna can be connected to the front of the SRX 600 receiver. It is referred to as AH0.There are several parameters related to Antennas that need to be set before data collection can begin. •Add antennas to an antenna group•Enter Gain values for each antenna •Enter Antenna Port numbers for each antenna • (optional) Designate radio antenna or hydrophone as a master• (optional) Assign Frequency or Antenna Priority for the scan cycle• (optional) Enable Master Antenna Preview• Set the receiver to use the ASP-8TYPES OF ANTENNASAntennas can be radio antennas or upconverted hydrophones. Radio antennas can be multi-element yagi, H-antennas, underwater antennas or whip antennas. Antenna inputs on the ASP-8 can also be used for hydrophones (underwater microphones). In order for the SRX 600 to use hydrophones the hydrophone must be connected to a UUC (ultrasonic upconverter), which is then connected to an antenna port on the receiver’s ASP-8. The UUC converts the hydrophone’s acoustic signals to radio signals.

. . . . .CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 59 UNDERSTANDING ANTENNA GROUPSAntennas can be radio or upconverted hydrophones. However, they are treated as separate groups by the receiver. For example, in an 8 antenna configuration, if radio antennas are connected to antenna ports 1,2, 4 and 6 then this is referred to as the Radio Group. If the rest of the ports available (3, 5, 7 and 8) are upconverted hydrophones then they are referred to as the Hydrophone Group.If there are no hydrophones used then there is no hydrophone group (likewise for radio antennas).ADDING ANTENNAS (RADIO AND HYDROPHONE)Antennas/hydrophones must be added in the order in which they should be scanned (scan order). However, the receiver treats the radio antennas as a radio group and the hydrophones as a hydrophone group (see Understanding Antenna Groups above for details). For example, the radio group may be connected to antenna ports 1, 2, 4 and 6, but if they are entered into the receiver in this order: 4, 2, 1 and 6, then that is their scan order. The same scenario could apply to a hydrophone group.Add an antenna to a group via Codelog > 1)Config## > 3)Ant or 4)Hydr > 1)Radio Ant Grp or 1)Acoustic Hydr Grp. The type of antenna must be selected first, whereby 3)Ant goes to the Radio Antenna Group page and 4)Hydr goes to the hydrophone group page.It is possible to add radio antennas and hydrophones alternately, but it requires switching back and forth between the radio antenna and hydrophone pages, which could be time consuming.Antennas are added using antenna port numbers and should be entered in the order that they should be scanned. Available antenna port numbers are from 1 through 8. After each antenna port number is entered, a slash [/] automatically appears to separate the antennas being entered (e.g. 1/4/5/2/8/6). Press the ENTER key to apply the changes (do not press the END/ESC key).

CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 60 5ASSIGNING A MASTER ANTENNA (OPTIONAL)The master antenna designation is used to place a priority on a particular radio antenna and/or hydrophone so that it is scanned before all other radio antennas and/or hydrophones. Assigning a master is not required for the receiver to operate. There can only be one master designation for each group; one for radio antennas and one for hydrophones (if both types are used).Master antennas are designated in one of two ways:• One master per group: There is only one master associated with each group. For example, a radio antenna on antenna port 2 can be assigned as the Radio Antenna Master and a hydrophone on Antenna Port 8 can be assigned as the hydrophone master. • All antennas are master antennas: when an antenna group is defined as the master antenna then all the antennas in that group are activated simultaneously (that is, their inputs are summed by the ASP-8). For example, if the Radio Group that uses antenna ports 1, 2, 4 and 6 is designated as the master, then all antennas in the group are scanned simultaneously. Likewise, if the hydrophone group is designated as the master hydrophone then the hydrophone ports on 3, 7 and 8 are scanned simultaneously (combined in the ASP-8). ASSIGNING A RADIO MASTERAssign a radio antenna as the Radio Master Antenna via Codelog > 1)Config## > 4)Ant/Hydr > 3)Ant > 2)Radio Master Ant. There are three possible selections:• Enter the value as 0 (zero) to make all radio antennas master antennas• Enter a value from 1 through 8 to make a single antenna the master. The value entered corresponds to an antenna port number on the ASP-8.• Enter the value as 9 to designate NO antenna as masterAfter a value has been entered the receiver returns to the page of menu selections.

. . . . .CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 61 ASSIGNING A HYDROPHONE MASTERAssign a hydrophone to be the master hydrophone via Codelog > 1)Config## > 4)Ant/Hydr > 4)Hydr > 2)Acoustic Master Hydr.

The value entered corresponds to an antenna port number on the ASP-8• Enter the value as 9 to designate NO hydrophone as masterAfter a value has been entered the receiver returns to the page of menu selections.ASSIGNING GAIN VALUESThe ASP-8 and all antennas must be assigned gain values. A typical starting gain value is 50, but should be set according to the requirements of the study.ASSIGNING GAIN VALUES TO ANTENNA PORTS ON THE ASP-8Assign gain values to each of the Antenna Ports on the ASP-8 via Codelog > 1)Config## > 4)Ant/Hydr > 4)Gain > 1)ASP-8 Gain. Enter the number of the antenna port to provide a gain value for. The display then updates to prompt for a gain value. Immediately after the appropriate gain value has been entered the display returns to the ASP8 Gain page. After the ASP8 Gain title in the display is a series of numbers in brackets. These numbers are the current gain value settings corresponding to an antenna port. They are listed in order from 1 to 8.ASSIGNING A GAIN VALUE TO THE ANTENNA PORT ON THE FRONTPANELAssign gain values to each antenna via Codelog > 1)Config## > 4)Ant/Hydr > 4)Gain > 2)AH0 Gain.

CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 62 5ASSIGNING GAIN VALUES TO MASTER ANTENNASAssign gain values to master antennas via Codelog > 1)Config## > 4)Ant/Hydr > 4)Gain > 3)Radio Master Gain or 4)Acoustic Master Gain. If the master designation has been set for all radio antennas or hydrophones in either the radio or hydrophone groups, then that gain value is used for all members of the group.SETTING A SCAN PRIORITYThere are three scan priorities to choose from: Frequency, Master Antenna Preview and Antenna. Antenna priority is completely independent of the other two, whereas Master Antenna Preview always uses Frequency Priority first and then uses its own rules to complete a scan.USING FREQUENCY PRIORITY FOR A SCANFrequency priority is used when it is desired to scan a single frequency using every applicable antenna before moving on to the next frequency in the frequency table selected. Any valid detections of transmitters that occur during scanning are recorded.Frequency priority is, by default, always enabled unless antenna priority is enabled.The antenna used to begin a scan depends on the type of frequency (radio or acoustic) that was the first entered into the frequency table. If this frequency was a radio frequency then the receiver starts with either the first radio antenna or the Radio Master Antenna in the radio group. If this frequency is an acoustic frequency then the receiver starts with either the first hydrophone or the hydrophone master in the hydrophone group. The following provides an example of how a simple configuration would proceed with scanning using frequency priority.In this example there are three frequencies, two radio and one acoustic, in a selected frequency table (on s 1 [acoustic], 2 [radio] and 3[radio]). They were entered into the frequency table in the scan order: {2, 3 and 1}. Frequency priority has been selected and there are 2 radio antennas in the radio group (4 and 7) and 2 hydrophones in the hydrophone group (5 and 8). Antenna 4 is the radio master

. . . . .CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 63 antenna and antenna 8 is the hydrophone master. The scan time is set to 15 seconds. The following illustrates the order in which scanning would take place:• Channel 2 is scanned using radio master 4 for 15 seconds• Channel 2 is scanned using radio antenna 4 for 15 seconds• Channel 2 is scanned using radio antenna 7 for 15 seconds• Channel 3 is scanned using the radio master antenna 4 for 15 seconds• Channel 3 is scanned using (radio master) antenna 4 for 15 seconds• Channel 3 is scanned using the radio antenna 7 for 15 seconds• Channel 1 is scanned using hydrophone master 8 for 15 seconds• Channel 1 is scanned using hydrophone 5 for 15 seconds• Channel 1 is scanned using hydrophone 8 for 15 seconds• The receiver then returns to the Radio Master Antenna and repeats the cycle until the scan is stopped, the battery expires or all the receiver’s data memory is used.Frequencies are scanned according to the order in which they were entered into the receiver (scan order). This order also determines which type of device, radio antenna or hydrophone, is used first in a scan cycle.ENABLING MASTER ANTENNA PREVIEWMaster Antenna Preview allows the receiver to conserve its power resources while waiting for a valid detection. If Total Scan Time is also enabled then further power savings can be achieved (refer to section on Enabling Total Scan Time for details).A Master Antenna must be defined for at least one antenna (or group of antennas) in order for Master Antenna Preview to work (refer to section above on Assigning a Master Antenna). If no master is designated for a particular group then the receiver defaults to using Frequency Priority to carry out the scan of that group.After the first frequency to be scanned is determined (first one in the frequency table), Master Antenna Preview allows the receiver to place a priority on the appropriate Master Antenna for that frequency. When a Master Antenna is scanned, the receiver scans only the Master Antenna for the Scan Time set. If a

CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 64 5valid detection is received within that time the receiver proceeds with scanning all applicable antennas (the Antenna Group) for only that frequency on which the initial detection was made. When the scan is complete the receiver moves on to the next frequency in the frequency table, which determines the group (radio antenna or hydrophone) that is scanned and using which master (if one is assigned).Below are several points that should be reviewed about Master Antenna Preview:• If no detection is made for the frequency+Master Antenna being scanned, the receiver moves on to the next frequency in the frequency table. The next frequency determines which group is scanned and using which master (if one is assigned).• If no master is designated for a particular group then the receiver defaults to using Frequency Priority to carry out the scan of that group. In other words, the frequency is scanned on all applicable antennas for the Scan Time set and then it moves on to the next frequency in the frequency table.• Master Antenna Preview also works if all antennas in either a radio antenna or hydrophone group are designated as masters. If all antennas in a group are masters then the receiver simultaneously scans all antennas in that group until it receives a valid detection, then it starts scanning the group according to its scan order.• Master Antenna Preview is automatically disabled if antenna priority is enabled. Enable Master Antenna Preview via Codelog > 1)Config## > 4)Ant/Hydr > 5)Priority > 2)En/Dis Master Preview. Selecting 2)En/Dis Master Preview changes the preview from being enabled or disabled. Watch the first line of the LCD display to know which setting is being applied.USING ANTENNA PRIORITYAntenna priority is used when it is desired to scan all frequencies in a frequency table before moving on to the next radio antenna/hydrophone. Any valid detections of transmitters that occur during scanning are recorded.

. . . . .CODELOG MODE1)Config## > 4)Ant/HydrGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 65 In this example there are three frequencies, two radio and one acoustic, in a selected frequency table (on channels 1 [acoustic], 2 [radio] and 3[radio]). They were entered into the frequency table in the scan order: {2, 3 and 1}. Antenna priority has been selected and there are 2 antennas in the radio group (4 and 7) and 2 hydrophones in the hydrophone group (5 and 8). Antenna 4 is the radio master antenna and antenna 8 is the hydrophone master. The scan time is set to 15 seconds. The following illustrates the order in which scanning would take place:• Radio master antenna 4 scans channel 2 for 15 seconds• Radio master antenna 4 scans channel 3 for 15 seconds• [radio master] antenna 4 scans channel 2 for 15 seconds• [radio master] antenna 4 scans channel 3 for 15 seconds• Radio antenna 7 scans channel 2 for 15 seconds• Radio antenna 7 scans channel 3 for 15 seconds• The receiver has now scanned both radio antennas for all radio frequencies and then moves on to the hydrophones• Hydrophone master 8 scans channel 1 for 15 seconds• Hydrophone 5 scans channel 1 for 15 seconds• [hydrophone master] hydrophone 8 scans channel 1 for 15 seconds• The receiver then returns to the radio master antenna and repeats the cycle until the scan is stopped, the battery expires or all the receiver’s data memory is usedWhen an antenna is being scanned the frequencies are scanned according to their scan order (the order they were entered into the frequency table).If an antenna group is designated as a master then all of the antennas/hydrophones in the group are scanned simultaneously.When antenna priority is enabled, master antenna preview is disabled.

This section of the manual describes two filter classes, one pertaining to signals (frequency/channel and transmitter ID) and the other to signal quality (signal strength and pulse timing).ID FILTERFiltering provides the ability to filter channel+ID combinations or IDs only without altering a configuration’s frequency table. IDs or channel+ID combinations can be accepted or rejected by creating accept or reject lists. Each accept or reject list can have up to 100 entries. There are four types of filters to choose from, but only one filter type can be selected at a time. Once a filter type is selected, the receiver uses the list created for that filter type to apply the settings.SETTING THE FILTER TYPEOnly one filter type can be selected at a time.

At any time an entry in the list can be deleted by pressing the 1 key [1)Del].PULSE FILTER (SIGNAL QUALITY)There are four filters available that pertain to the signal strength and timing characteristics of pulsed signals: Echo Filter, Noise Threshold, Pulse Width and Signal Strength Deviation. All of these filters set pass/fail boundaries based on selected pulse characteristics.SETTING AN ECHO FILTERThe Echo Filter sets the time in milliseconds after a valid detection during which any additional detections are considered to be echos.

CODELOG MODE1)Config## > 5)FiltersGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 70 5This filter was originally (SRX 400) provided for use with acoustic transmitters, where multipath propagation at the speed of sound can cause mirror reflections on the order of several milliseconds. However, this filter currently provides the ability to reject pulses when the time interval between two pulses is below the Echo Filter time. As a result, this feature speeds up the receiver's processing time. Please contact Lotek Wireless Inc. for details on how to determine an appropriate Echo Filter time.SETTING THE NOISE THRESHOLDThe Noise Threshold is a minimum allowable detection signal strength. This means that if the receiver detects a pulse that has a signal strength equal to or less than the noise threshold it is rejected and not used for further code processing.Typically the noise threshold is set to 30, but should be set to reflect the environment in which a study is taking place. Set the noise threshold via Codelog > 1)Config > 5)Filters > 2)Pulse Filter > 2)Noise Threshold. The maximum noise threshold value that can be entered is 99.ENABLING/DISABLING THE PULSE WIDTH FILTERThe minimum Pulse Width filter threshold is defined through the SRX Host, but us typically set to 2ms. With the filter enabled, pulses with a measured pulse width less than the pulse width filter (e.g. 2ms) are discarded.Enable or disable this feature via Codelog > 1)Config > 5)Filters > 2)Pulse Filter > 3)Pulse Width > 1)Enable or 2)Disable. The display shows the current setting in brackets using the number of the menu items available. For example, if pulse width filter is disabled then the number in brackets is 2.ENABLING/DISABLING THE SIGNAL STRENGTH DEVIATIONThe signal strength deviation filter applies to codes (sequences of pulses), and is used to reject codes whose individual pulses exhibit a large variance. This feature is useful for detecting code collisions, where two codes with different signal strengths are overlapped.

Enable or disable this feature via Codelog > 1)Config > 5)Filters > 2)Pulse Filter > 4)Signal Strength Dev > 1)Enable or 2)Disable. The display shows the current setting in brackets using the number of the menu items available. For example, if signal strength deviation is disabled then the number in brackets is 2.

CODELOG MODE1)Config## > 6)SensorsGuide to the SRX 600 receiver Rev A #10112 Chapter 5 - - Page 72 51)CONFIG## > 6)SENSORSThe receiver needs to know the Sensor Class and the types of sensors that are used by the transmitters in a study.There are four types of sensors available: temperature, pressure, activity and EMG. Only three types can be used by the receiver at any given time. In order for the receiver to interpret and display the sensor data properly, it must know the sensor’s range and granularity. These are characterized by three numbers: the Minimum and Maximum (measurement values) and the Level (number of measurement levels). All of these values entered here (class and type, as well as minimum, maximum and levels for all types) are normally provided on the shipping sheet that came with the transmitters from Lotek Wireless Inc.SETTING THE SENSOR CLASSThe sensor class is an internal parameter that the receiver needs to interpret and display sensor data. All transmitters in a study must belong to the same class. Set the sensor class via Codelog > 1)Config > 6)Sensors > 1)Class. Enter a value between 0 and 9. After a value has been entered the receiver automatically returns to the Sensors page.SELECTING THE SENSOR TYPESCoded transmitters equipped with sensors can combine up to three sensor types in a single transmitter. The particular sensor combination in use must be known to the receiver.Select the sensor types via Codelog > 1)Config > 6)Sensors > 2)Type. The display automatically places a slash [/] between each selection (e.g. 1/2/3). A maximum of three sensor types can be entered. The number of the selection corresponds to the menu item number, for example, press key 3 to select the activity sensor type and the number 3 appears in the display. After three selections have been made the receiver automatically returns to the Sensors page. If fewer than three selections are made, press the Enter key to apply the changes and go back to the Sensors page.

Once a scan is started no changes can be made to the active configuration, except when the scan is paused. The only actions that can be taken at this point are the following:ADJUSTING FREQUENCY AND GAINGo to the next/previous applicable frequency in the frequency table used by the active configuration using the Up or Down Arrows. A new gain can be selected using the Up or Down Arrows. The amount of increment or decrement is specified by Set Delta for gain (see section called Set Delta in chapter 1 for details).PAUSING A SCANAccessed via Codelog > 2)Scan > 1)Continue to Log Data > 0)Pause Scan. This function suspends the scan cycle on the frequency and antenna that was being scanned when pause was selected. The receiver does not change the frequency or antenna it was scanning when pause was selected, but it does continue logging data for that frequency and antenna. Any settings changed while paused are only applied to the frequency and antenna that the receiver was scanning when pause was selected.

Up to 64 valid detections can be accumulated for viewing during a scan. After 64 initial valid detections have been made the receiver starts replacing the oldest detection with the most recent and so on (this affects viewing only). The receiver does not stop collecting data while using this feature.Access the display scroll via Codelog > 2)Scan > 1)Continue to log data > 2)View > 1)Display Scroll.

While attempting to acquire a position, the display shows the number of satellites as they are found.If a valid position is acquired the following information is provided in the display: Latitude, Longitude, current date, current GMT time, the number of satellites used, HDOP and PDOP. The display flips back and forth between showing the Latitude and Longitude for 4 seconds and the satellites, HDOP and PDOP information for 2 seconds. Either the time or date are also shown on the display and are updated every 5 seconds.GPS cannot be used if the receiver is logged off. However, it is possible to log off from the receiver while the receiver is attempting to acquire a GPS position. When logging back on, the display shows the results of the GPS position.CRTO cannot be used with the GPS 2D positioning feature of the receiver, however it still allows the GPS clock to function.RESUMING A SCANUpon resuming a scan (Codelog > 2)Scan > 0)Pause Scan > 0)Resume Scan), the receiver uses the last settings applied during the pause, thereby replacing the original values in the active configuration.STOPPING A SCANPress the END key to stop an active scan.
