Introduction:
The R4500S is a receiver - data logger combination with built in GPS. (An optional GPS antenna is required to use
the GPS feature)
Operationally, the R4500S works by acting as a filter to select a very narrow window in the frequency spectrum.
The position of this filter in the frequency spectrum is determined by the frequency selection (tuning). The receiver
rejects signals and noise outside the filtered window, and passes signals and noise within the window. Additionally,
the receiver translates the signal to a frequency within hearing range that can be heard from the speaker.
The R4500S can store 98304 Stationary data blocks, or 49152 Aerial data blocks or data blocks recorded in the
Manual mode. For Aerial Data, and data recorded in the Manual mode, an extra data block is needed for GPS
information. The data is stored to memory using a looping format. If the data set is maxed out, the newest data will
overwrite the oldest data block. Data blocks consist of the time stamp, frequency, transmitter data, and GPS
location if GPS is used.
The Receiver uses DSP (Digital Signal Processing) technology to achieve better sensitivity, and to help filter out
noise. The DSP digitally samples the audio signal from the R4500S. When the signal has been digitized, the DSP
processor uses internal mathematical calculations to identify signals.
The S suffix indicates the software in this receiver is programmed to detect non coded transmitters.
A non coded transmitter transmits a single pulse which is repeated at a specific pulse rate.
The R4500S can be used for fixed pulse rate transmitters, and for variable pulse rate transmitters.
For fixed pulse rate transmitters, the R4500S uses a pattern matching algorithm to detect up to 3 user entered
pulse rates. To verify a pulse rate, the pattern matching algorithm uses 4 pulses from the transmitter to verify the
pulse rate which helps separate a transmitter signal from a noise pulses. This is important to know for setting the
correct scan time for detecting pulse rates as described in sections 13.0 – 15.0.
For variable rate transmitters (temperature, depth, altitude), the R4500S uses a pattern matching algorithm to
identify transmitter pulse periods, and converts the period to the actual measurement using 2nd order regression
coefficients required to be entered for each transmitter.

Getting Started:
When you first turn on the power, the receiver will display Advanced Telemetry Systems, the receiver model and
the version number of the receiver software. The display will then proceed to the Main Menu:
Main Menu Items:
GPS indicator: The status of the GPS is displayed in the upper right corner of the screen. The messages indicate
the following:
GPS (non flashing) – The GPS is on, and there is a valid GPS fix.
GPS / OFF – The GPS is turned OFF.
NO / FIX – The GPS is attempting to acquire a valid GPS fix.
GPS / ERR – The GPS has not been able to get a valid GPS fix within 120 seconds.
NO / GPS – The GPS has not been able to get a valid GPS fix after 15 minutes.
If a valid GPS fix is found during NO /FIX, GPS / ERR, or NO / GPS the indicator will change to a non flashing GPS
indicator.
MANUAL: This mode is used to detect transmitters on an individual frequency. Frequency scanning is not available
in this mode. The manual mode does not use pattern matching. The actual pulse rate between any two pulses will
be displayed. Without any pattern matching, the manual mode is helpful to identify a transmitter pulse rate if it is
not known. To save a target in the manual mode, Record would need to be activated. When Record is activated,
GPS locations are also recorded along with the transmitter data if GPS is activated. An optional GPS antenna is
required to use the GPS feature.
AERIAL: Designed for transmitter location using aircraft, but can easily be used in any other vehicle. While
scanning a table usually a small scan time is used to cycle through the frequency table quickly, and does not allow
enough time for the R4500S to identify a pulse rate on each frequency. To remain on a specific frequency for a
longer period of time to allow the R4500S to identify the pulse rate, Hold will need to be activated. When Hold is
activated, the scanning of the frequencies in the frequency table stops and is held for the frequency shown in the
screen until Hold is pressed again. While in Hold, all available information will be continually stored. The
transmitter pulse rate, frequency, signal strength and time are stored to memory when the operator exits Hold or
activates Record. While In Hold, Record needs to be activated when no pulse rate is detected but a transmitter
can still be heard. GPS locations are also recorded along with the transmitter data if GPS is activated. An optional
GPS antenna is required to use the GPS feature.
STATIONARY: This mode is used to monitor transmitters passing a site or presence/absence of transmitters. The
time, frequency, signal strength, transmitter pulse rate, and the number of valid transmitter detections per store
period are stored. Scanning is enabled, GPS is disabled.
PC: Used to off load data, send/receive frequency tables and to send/receive receiver programming parameters.
The supplied ATSWinRec software and serial cable must be used with this option.
CLONE: Using the optional blue cable, frequency tables and default settings may be cloned from one receiver to
another receiver.

Receiver Controls:
Receiver controls are shown in the figure below. Most are self explanatory. The RF Gain control is normally set to
full clockwise for maximum sensitivity. RF Gain may be reduced for close in searching or while direction finding.
The Audio control should be set for a comfortable level. Its setting does not affect detection sensitivity. Any
monaural headset with a 0.25 inch jack may be used. Most users prefer headsets with muffs to reduce external
noise from wind or aircraft. Inserting the headset jack disables the internal speaker.
The AUX connector is used to interface antenna switches or other controlled devices.
The SIG LED will light for every valid pulse detected. See specifications for valid pulse detections.
Most input and control of the receiver is done through the keypad. The keypad is shown below:

1.0 Frequency Entry Mode
Stationary Mode and Aerial Mode will not function if there are no frequencies in the table selected to scan. The
frequencies should be entered into the frequency table or tables first.
Frequency Entry Mode – Fixed Rate Transmitter
The frequencies entered in the R4500S are 6 digit numbers. For frequencies below 100 MHz, the frequencies are
entered as 5 digit numbers. For example, a frequency of 151.183 MHz will be entered as 151183. A frequency of
48.655 MHz will be entered as 48655.
From the Main Menu screen, press the “SHIFT” key followed by pressing the “FREQ” key sequentially. To change
the numeric value, use the numeric digits on the keypad. For the R4500S to accept a value, press “ENTER”.
Screen 1
Table # : Selects the frequency table that you will be storing your transmitters’ frequencies. There
are four tables available. Table 1, 2, 3 or 4.
Chan Qty : The number of frequency entries you will be using for the transmitters in this table. Note
the first channel is Channel (00). There are 100 channels available for each frequency
table.
After entering the Chan Qty, the screen will change to entering the frequencies.
Screen 2
(The default frequency will be the lowest frequency of the receiver)
FR1 indicates frequency table 1.
(00) represents the first frequency in the list. The next frequency will be FR1(01), and so on.
The cursor defaults to the 1 MHz position. Use the or the keys to move the cursor to the digit that needs
changing. When a number is entered in one location, the cursor will move to the right by one. Pressing “ENTER”
will store the frequency, and move to the next frequency position in the table. When all the frequencies are
entered, the screen will jump back to the start of the Frequency Entry Menu.
If you have overlapping frequencies (i.e. 148.000-151.999) move the cursor to the 10 MHz position and then enter
the desired numeric value.
You may use the CHAN up and CHAN down keys at any time to scroll through the channels. These
keys can be used to make corrections or change an individual channel frequency.
Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 11
Frequency Entry Mode – Variable Rate Transmitter
The R4500S uses a second order regression to convert the incoming pulse rate to the specified measurement (i.e.
temperature, altitude, and depth). Each transmitter will behave uniquely and should have its own associated
equation. This information should be included in the calibration data we send out with the transmitters. The values
to be entered will be highlighted on the transmitter paperwork.
The following is an example for a Temperature transmitter:
Temperature = Ax2 + Bx + C
1. x is the transmitter period.
2. A, B and C are calibration constants, an example set is listed below:
a. A = 0.000012897 => value entered is 1290
b. B = -0.09435789 => value entered is –9436
c. C = 111.99245 => value entered is 11199
This data for the transmitter types: temperature, depth, or altitude will be entered along with each transmitter
frequency. When entering frequency data for variable pulse rate transmitters the prompts will automatically appear
for ‘A’,’B’ and ‘C’.
Because each one of these calibration constants will take up the space used for entering one frequency the
maximum number of frequencies that each table can store will now be 50.
This calibration data will also be requested in the defaults menu when setting up your reference frequency if a
reference transmitter is used.
The frequencies entered in the R4500S are 6 digit numbers. For frequencies below 100 MHz, the frequencies are
entered as 5 digit numbers. For example, a frequency of 151.183 MHz will be entered as 151183. A frequency of
48.655 MHz will be entered as 48655.
From the Program menu screen, press the “SHIFT” key followed by pressing the “FREQ” key sequentially. To
change the numeric value, use the numeric digits on the keypad. For the R4500S to accept a value, press
“ENTER”.

A, B, and C represent values for the second order regression equation mentioned earlier.
The cursor defaults to the 1 MHz position for entering the frequency. Use the and the keys to move the
cursor to the digit that needs changing. When a number is entered in one location, the cursor will move to the right
by one. Pressing enter will store the frequency, and move to the next frequency position in the table. When all the
frequencies are entered, the screen will jump back to the start of the Frequency Entry Menu.
If you have overlapping frequencies (i.e. 148.000-151.999), move the cursor to the 10 MHz position and then enter
the desired numeric value.
You may use the CHAN up and CHAN down keys at any time to scroll through the channels. These
keys can be used to make corrections or change an individual channel frequency.

Screen 4
(A = Store Rate or Log Period, see below)
Time Out: The amount of time the receiver will stay on a Frequency while attempting to
detect a transmitter. If no transmitter is detected in the Time Out period, the
receiver will advance to the next frequency in its frequency table. This feature
allows faster scanning by truncating the scan time if no transmitter is detected in
the Time Out period. The user defines the parameter (Range = 001 – 300
seconds). Refer to section 14.0 for information on setting the Time Out value.
Scan Time: The amount of time to hold on a frequency and attempt to detect transmitters. The
Scan time will override the Time Out time, if a pulse has been detected during the
Time Out period. The Scan Time is set to whatever you need this set at (Range =
001 – 300 seconds). Refer to section 15.0 for information on setting the Scan
Time value.
A: If Continual (1) was selected in screen 1 this will read Î Store Rate
If Periodic (2) was selected in screen 1 this will read Î Log Period
Store Rate: This defines how often a transmitter’s detection will be stored for
each antenna (Range = 0000 – 1440 seconds). For example if the
Store Rate is set to 10 minutes and a scan time of 15 seconds, its
presence will only be recorded once during that 10 minute period.
The data stored will include the time stamp of the strongest signal
strength measured in one 15 second scan time during the 10
minute scan period. Stored with it will be a total number of pulses
that the receiver determined to be pulse rates during the 10 minute
store period along with the total number of pulses detected during
the Store Period.
Log Period: This defines the time interval between the receiver cycles where
the R4500S performs one scan of the frequency table.
Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 19
(Range = 0000 – 1440 seconds). If the scan of the frequency
table takes the entire log period, the receiver will never pause
between the end of a frequency table scan, and the start of the
next one.
Screen 5
Table # : The frequency table you want to scan. There are four tables available.
Antenna # : The number of antennas the receiver will sample. This feature requires an
external antenna switchbox connected to the AUX port of the R4500S if using
more than 1 antenna. If using a 2-way switchbox, this would be set to 2.
Reference Freq: Pressing “ENTER” while the cursor is on NO will bring the screen back to the
Default Menu.
To activate the Reference transmitter feature, use the or the key. These two keys are used to toggle
between the two choices.
If you entered YES for the reference transmitter, you will be prompted to enter the reference transmitter frequency,
and the store rate of the reference transmitter.
Screen 6
Reference Freq: This is the frequency of a transmitter set up within range of your station used as a
check on the system. Since you will not need the same quantity of data you can
set up a longer store period to use up less memory. Instead of the strongest signal
strength being stored within the storage period, it will be the time of the first valid
pulse rate detected.
Store Rate: This defines how frequently the data from the reference transmitter will be stored.
A count of the number of detected pulse rates will be stored for the entire store
rate. (Range = 0005 – 1440 seconds)
Note: The data are not stored until the storage period has expired. For example with storage period set up for once
an hour the time the first data are collected might be at 6:00 am. Although the data recorded will reflect 6:00 they
will not be committed to memory until 7:00 am. This means when the data are offloaded you may have the data for
the actual transmitters appearing before the reference transmitter. This is true even if the animal data were
collected at 6:30 am and the reference data were collected at 6:00 am.

scan the frequency table once again until an entered amount of time has elapsed.
The amount of time entered between scans (Log Period) is entered when starting
a Stationary Scan.
Screen 2
The number entered here should represent the range of pulse rates you are using in your study. The available
period range allowed to be entered is between 400ms to 2500ms.
The periods measured from signals that are outside the entered range will be thrown out.
Screen 3
(A = Store Rate or Log Period, see below)
Time Out: The amount of time the receiver will stay on a Frequency while attempting to
detect a transmitter. If no transmitter is detected in the Time Out period, the
receiver will advance to the next frequency in its frequency table. This feature
allows faster scanning by truncating the scan time if no transmitter is detected in
the Time Out period. The user defines the parameter (Range = 001 – 300
seconds). Refer to section 14.0 for information on setting the Time Out value.
Scan Time: The amount of time to hold on a frequency and attempt to detect transmitters. The
Scan time will override the Time Out time, if a pulse has been detected during the
Time Out period. The Scan Time is set to whatever you need this set at (Range =
Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 21
0000 – 1440 seconds). Refer to section 15.0 for information on setting the Scan
Time value.
A: If Continual (1) was selected in screen 1 this will read Î Store Rate
If Periodic (2) was selected in screen 1 this will read Î Log Period
Store Rate: This defines how often a transmitter’s detection will be stored for
each antenna (Range = 0000 – 1440 seconds). For example if the
Store Rate is set to 10 minutes and a scan time of 15 seconds, its
presence will only be recorded once during that 10 minute period.
The data stored will include the time stamp of the strongest signal
strength measured in one 15 second scan time during the 10
minute scan period. Stored with it will be a total number of pulses
that the receiver determined to be pulse rates during the 10 minute
store period along with the total number of pulses detected during
the Store Period.
Log Period: This defines the time interval between the receiver cycles where
the R4500S performs one scan of the frequency table.
(Range = 0000 – 1440 seconds). If the scan of the frequency table
takes the entire log period, the receiver will never pause between
the end of a frequency table scan, and the start of the next one.

2.3 Tx Type
This is used to select what type of transmitters you want to monitor.
Enter a 1 or 2 for the type of transmitter and press “ENTER”.
2.3.1 Fixed pulse rate
Most transmitters will have a pulse rate that does not change. This is the default setting. After choosing the Fixed
PulseRate, a new screen will appear to select the default type of scan.
Screen 2
Pattern Matching: Pattern Matching is the default type of scan. With Pattern matching, 4
consecutive pulses are needed to determine if the pulse rate is valid, given
the information entered for the pulse rates before starting an Aerial Scan
or a Stationary Scan. Also the R4500S will check to see if the incoming
pulse rates are within the tolerances entered for each pulse rate. If the
pulse rates do not match the entered information, the pulse rate will be
thrown out. This Pattern Matching method helps to filter out noise
pulses. A noise pulse is defined as any pulse that is not wanted to be
received.
PulsesPerScan Time: Pulses per Scan Time will count all pulses detected during each scan time,
and stored during the scan period. No noise filtering is used, and
no pulse rate information is available.
Enter a 1 or 2 for the type of scan and press “ENTER”. The screen will return to the “Defaults Menu”.
Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 24
2.3.2 Variable PulseRate
A variable pulse rate transmitter has an added sensor that will vary the pulse rate to indicate an external
measurement: temperature, altitude, depth, and period.
A period type scan does not use coefficients when entering frequencies and the actual period will be stored.
When using temperature, altitude, or depth, the converted measurement will be displayed using the entered
coefficients for each frequency.
The R4500S uses a second order regression to convert the incoming pulse rate to the specified measurement (i.e.
temperature, altitude, and depth). Each transmitter will behave uniquely and should have its own associated
equation. This should be included in the calibration data we send out with the transmitters. The values to be
entered will be highlighted on the transmitter paperwork.
The following is a second order regression example for a Temperature transmitter:
Temperature = Ax2 + Bx + C
x is the transmitter period.
A, B and C are calibration constants and need to be entered for the to display converted data.
Move the cursor with the or the to choose what type of measurement data you want to collect and store
and press “ENTER”.
2.4 Stat Hold
(This time setting is only used only for a Stationary Scan and is not used for Hold during Aerial Scanning)
Stat Hold is abbreviated for Stationary Hold time (Range = 00005 to 65535 seconds). The Stationary Hold time is
the number of seconds the “HOLD” feature can remain in the Hold position when activated during a Stationary
Scan. Pressing “HOLD” before the Stat Hold time has expired will resume the stationary scan. The “HOLD”
feature may be used to monitor a transmitter for a period of time longer than the Scan Time during a Stationary
Scan. If the user does not exit the “HOLD” mode, the R4500S will automatically resume scanning after the number
of seconds has been reached. This is a safety feature added to prevent the possibility of a stationary scan
remaining in Hold at a remote location.
Pressing “ENTER” or “ESC” from the “Stat Hold” menu will bring you back to the “Setup Menu”.
Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 25
2.5 Antenna 0 Delay
During a stationary scan, “Antenna 0” is the indicator for all antennas ON. The Antenna 0 Delay is not activated
when using 1 antenna for a stationary scan. The Antenna 0 Delay will be activated when 2 to 8 antennas are
selected for a stationary scan. The available delay time is 0-5000 milliseconds. The default Antenna 0 Delay time
is 1000 milliseconds (1 second). The purpose of the Antenna 0 Delay is to filter out unwanted noise pulses when
switching frequencies. The R4500S filters out unwanted noise pulses during the Antenna 0 Delay time by ignoring
all pulses detected during the entered time, 0 – 5000 milliseconds. The scan time of each frequency does not start
until the Antenna 0 Delay time has expired.
This adjust is available for cases where the noise level changes significantly when frequency channels are
changed. The R4500S measures the average background noise level and adjusts the detection level accordingly. If
the background noise level changes dramatically between channels, more time is needed to adjust to the new
threshold level. When using multiple antennas the system monitors all antennas for the first two seconds (Time Out
setting), if there are no pulses present, the search on all antennas is terminated and any other antennas are
skipped. This saves scan time and allows all channels to be searched more often.
To determine if extra delay is needed, cycle through the frequency table with no transmitters present to determine
if noise pulses cause the receiver to cycle through the multiple antenna sequence. If the receiver scans through all
antennas on several or all frequency channels even with no signal present; you may want to increase the Antenna
0 Delay time. If noise pulses are present, and the multiple antenna scanning sequence does not start, the Antenna
0 Delay time is set correctly.
Setting the Antenna 0 Delay time longer gives more time for the R4500S to set a new threshold and optimize
sensitivity while at the same time ignoring noise. Setting it longer than necessary means the additional delay will be
added to every frequency channel scanned also increasing the time for all channels to be scanned. Thus the goal is
to set the delay so most, but not necessarily all noise pulses on every channel are ignored. Occasionally high level
noise will still pass no matter how long the delay is made.
Example of scan times with no transmitters present: Number of antennas used = 2. Time out = 3 seconds. Scan
time = 10 seconds. Number of frequencies used in table scanned = 10.
If the noise level is higher than the noise threshold level the R4500S has set, the noise will produce signal pulses
and the receiver will think transmitters are present and then cycle through the individual antennas. With no
transmitters in the area, but with noise pulses indicating possible presence of transmitters, the time for a scan of the
complete frequency table will be: Scan Time of antenna 0 + Time Out of antenna 1 + Time Out of antenna 2 = 10 +
3 + 3 = 16 seconds. For the10 frequencies in the table, the total scan time will be 160 seconds. (When an individual
antenna is selected, the noise level decreases and there should not be any noise pulses produced)
When using the default Antenna 0 Delay of 1000 milliseconds and there are no noise pulses above the threshold
nor are any transmitters present; the time of the frequency table scan will be: Antenna 0 Delay time + Time Out of
antenna 0 = 1 + 3 = 4 seconds. For the10 frequencies the total scan time would be 40 seconds. With the Antenna 0
Delay set correctly, scan times can be reduced by allowing time for the R4500S to set the correct noise threshold
level.
Enter a numeric number from 0 to 5000 and press “ENTER”.
Pressing “ENTER” or “ESC” will return the screen back to the “Setup Menu”.

3.0 Main Menu
3.1 MANUAL MODE
With the cursor in the MANUAL position, press “ENTER”.
The manual mode does not use pattern matching as the Stationary Mode and Aerial Mode use to detect incoming
pulse rates. In the Manual mode screen, the Period and the Pulse Rate are displayed for any two pulses detected.
There is a 0-9 single digit counter located after the 4 digit Period. This counter will increment every time a pulse
has been detected and will keep incrementing and looping from 0-9 for every duplicate pulse rate. A new pulse
rate will clear the count.
The GPS is normally OFF for the Manual Mode. If the GPS has been turned on previously from the GPS Menu, or
an Aerial Scan, the GPS will remain on when entering the Manual Mode.
The Manual mode does not automatically store the data. To store data in the Manual mode the RECORD feature
can be used. All information in the display will be stored when pressing “SHIFT” and then “RECORD” sequentially.
The latest time stamp and an accumulative count of the detected pulses and consecutive pulse rates will be stored.
When the RECORD feature is activated, “Saving targets” will flash in the display
To change the frequency
The cursor defaults to the 1 MHz position. From here you can enter whatever frequency you are looking for.
You may use the or the keys to change the cursor position. More likely you will enter transmitter
frequencies using the keypad. Each time you enter a digit the cursor will move one place to the right. If the cursor
is in the 1 kHz position (least significant digit), then it will just remain in that location. Receiver frequency is also
updated after each key is entered.
Pressing “ENTER” will move the cursor to the default location of the 1 MHz position. It does not change the last
entered frequency. You may also use the left and right arrow keys to move the cursor around and change the
frequency by entering a new digit.
The and the keys can be used to increment or decrement a numeric value while keeping the cursor in
the same location.
If the enter frequency that is not within the receiver’s range, “Out of range” error will be displayed.
To exit the Manual mode, press the “ESC” key.

Screen 3
PR1-PR3: The pulse rates of your transmitters in pulses per minute. (Range = 020ppm – 250ppm)
TOL : The tolerance is a +/- pulse rate range in ppm used to filter the incoming signal. The
tolerance may be set in the range of 00ppm to 10ppm. There is always a +/- 10ms buffer
added to the tolerance setting. A tolerance of 1 for PR2: 045 would indicate the R4500S
should accept signals coming in that range from 44ppm (1364ms) to 46ppm (1304ms) +/-
10ms = 1374ms to 1294ms. A tolerance of zero indicates the R4500S should accept only
signals that are the specified range +/- 10ms (i.e. PR1:055 should always be 55ppm
(1091ms) +/- 10ms = 1081ms to 1101ms). You can use a zero tolerance when using ATS
microprocessor transmitters. A larger tolerance will be needed on transmitters that have a
pulse rates that can drift with temperature or age.
If the defaults were set up correctly, just press enter for each item listed, and the cursor will move through each
setting in the Aerial Setup windows. When all settings have been entered, the Aerial scan will start.

Screen 1
Continual: The R4500S will continually scan through the selected frequency table.
Periodic: The R4500S will scan through the selected frequency table and shut the power off
for a period of time.
Screen 2
The number entered here should represent the total number of pulse rates you are using in your study. There
should not be more than one transmitter per frequency. If you need to use multiple transmitters per frequency you
should consider using a coded receiver and coded transmitters.
Screen 3
Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 34
PR1-PR3: The pulse rate of your transmitter in pulses per minute. (Range = 020ppm – 250ppm)
TOL : The tolerance is a +/- pulse rate range in ppm used to filter the incoming signal. The
tolerance may be set in the range of 00ppm to 10ppm. There is always a +/- 10ms buffer
added to the tolerance setting. A tolerance of 1 for PR2: 045 would indicate the R4500S
should accept signals coming in that range from 44ppm (1364ms) to 46ppm (1304ms) +/-
10ms = 1374ms to 1294ms. A tolerance of zero indicates the R4500S should accept only
signals that are the specified range +/- 10ms (i.e. PR1:055 should always be 55ppm
(1091ms) +/- 10ms = 1081ms to 1101ms). You can use a zero tolerance when using ATS
microprocessor transmitters. A larger tolerance will be needed on transmitters that have a
pulse rates that can drift with temperature or age.
Screen 4
(A = Store Rate or Log Period, see below)
Time Out: The amount of time the receiver will stay on a Frequency while attempting to
detect a transmitter. If no transmitter is detected in the Time Out period, the
receiver will advance to the next frequency in its frequency table. This feature
allows faster scanning by truncating the scan time if no transmitter is detected in
the Time Out period. The user defines the parameter (Range = 001 – 300
seconds). Refer to section 14.0 for information on setting the Time Out value.
Scan Time: The amount of time to hold on a frequency and attempt to detect transmitters. The
Scan time will override the Time Out time, if a pulse has been detected during the
Time Out period. The Scan Time is set to whatever you need this set at (Range =
001 – 300 seconds). Refer to section 15.0 for information on setting the Scan
Time value.
A: If Continual (1) was selected in screen 1 this will read Î Store Rate
If Periodic (2) was selected in screen 1 this will read Î Log Period
Store Rate: This defines how often a transmitter’s detection will be stored for
each antenna (Range = 0000 – 1440 seconds). For example if the
Store Rate is set to 10 minutes and a scan time of 15 seconds, its
presence will only be recorded once during that 10 minute period.
The data stored will include the time stamp of the strongest signal
strength measured in one 15 second scan time during the 10
minute scan period. Stored with it will be a total number of pulses
that the receiver determined to be pulse rates during the 10 minute
store period along with the total number of pulses detected during
the Store Period.
Log Period: This defines the time interval between the receiver cycles where
the R4500S performs one scan of the frequency table (Range =
0000 – 1440 seconds). If the scan of the frequency table takes the
entire log period, the receiver will never pause between the end of
a frequency table scan, and the start of the next one.

Reference Freq: Pressing “ENTER” while the cursor is on NO will the Stationary Scan start.
To activate the Reference transmitter feature, use the or the key. These two keys are used to toggle
between the two choices.
If you entered YES for the reference transmitter, you will be prompted to enter the reference transmitter frequency,
and the store rate of the reference transmitter. After entering the reference frequency transmitter information, the
Stationary Scan will start.
Screen 6
Reference Freq: This is the frequency of a transmitter set up within range of your station used as a
check on the system. Since you will not need the same quantity of data you can
set up a longer store period to use up less memory. Instead of the strongest signal
strength being stored within the storage period, it will be the time of the first valid
pulse rate.
Store Rate: This defines how frequently the data from the reference transmitter will be stored.
A count of the number of detected pulse rates will be stored for the entire store
rate. (Range = 0005 – 1440 seconds)
Note: The data are not stored until the storage period has expired. For example with storage period set up for once
an hour the time the first data are collected might be at 6:00 am. Although the data recorded will reflect 6:00 they
will not be committed to memory until 7:00 am. This means when the data are offloaded you may have the data for
the actual transmitters appearing before the reference transmitter. This is true even if the animal data were
collected at 6:30 am and the reference data were collected at 6:00 am.

Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 50
Recover Deleted Data allows you to recover deleted data. When deleting data, a data pointer that is used to store
memory in the R4500S is reset, and when recovering deleted data, the data pointer can be returned to the previous
location. Thus data can be recovered if the data has not been overwritten by resetting the pointer. When the
R4500S memory is maxed out, the newest data will start writing over the oldest data blocks. Recovering deleted
data will only work for the last data set deleted.
You may also set the starting data block to be greater than zero. For example you may only want to check the most
recent data.
You can select the coordinate for the GPS data.
You can select the frequency data displayed with all six digits or with the two most significant digits suppressed.
Showing parameters in the offloaded data, will add scanning information for Aerial, Stationary, and Manual modes.
All scan parameters will be available for viewing at the start of each scan when selected. If scan parameters have
not been changed between similar scans, the scan parameters will not be displayed for new scans after stopping a
similar scan. Only when the scan parameters have been changed, will they be displayed for a new scan.
The figure below shows downloaded data with first an Aerial Scan, then a Manual Scan, then a Stationary Scan.
Steps for Offloading:

Tables mode, no parameters can be modified.
When editing a frequency table the source can be; from a file, from a receiver connected the PC, or a new
frequency table can be created using ATSWinRec. A group of 4 tables can be entered for editing, or a single table
can be entered for editing.
The frequency files are saved as a group (4 tables) – FileName_grp.csv or as a single table – Filename_tbl.csv.
Group Frequency Tables
When opening a file of 4 frequency tables, ATSWinRec will be looking for a file with the extension *_grp.csv. A
single frequency table file (file name with extension *_tbl.csv) will not be allowed to be opened.
When sending a group (4 tables) of frequency tables to the receiver only tables with frequencies will be sent. Also,
the option to only send selected tables to the R4500S is available by deselecting any frequency table tabs not
wanting to be sent.
Single Table Frequencies
When opening a file for a single frequency table, ATSWinRec will be looking for a file with the extension *_tbl.csv.
A group table file (file name with extension *_grp.csv) will not be allowed to be opened.
If a file is saved as a single table, the file can be loaded to any selected frequency table and sent to the receiver by
selecting the corresponding frequency table tab. Selecting the tab for the frequency table location is available for

opening a file, saving a file, or sending the table to the receiver. When loading a single table from a file or saving a
single frequency table to a file, each table selected to be loaded or saved, will have a “Windows” open file dialog
box for each file. The upper left corner of the open file dialog box will show the frequency table number which the
file will be saved to, or loaded to. The figure below is opening a single frequency table file for table 3.
If a receiver is not connected to the PC when a new frequency table is created, the lowest frequency of the receiver
will need to be entered. If the wrong lowest frequency is entered when creating a new frequency table, the table
will not be sent to the receiver and an error message will appear indicating that the lowest frequencies do not
match.
The frequency table editing is set up in a row – column format. A particular frequency can be selected by
advancing with the “Entry Number” keys, or more quickly with the “Row” and “Column” keys if the table is large.
By selecting a specific entry number, the frequency can be replaced with a different value, deleted, or a new
frequency can be added at that particular location.
12.3.4 Delete Data
Selecting Delete Data will delete the data in the receiver. Warning messages will appear in case if the tab was
accidentally selected.

13.0 Setting Aerial Scan Rate
The minimum Aerial Scan Rate should be set to allow for a single pulse from the transmitter with the longest pulse
repetition period to be heard.
So, for a 45ppm transmitter, the minimum scan rate should be set for 2 seconds so at least one pulse will be heard.
You may use the CHAN up and CHAN down keys at any time to scroll through the channels while
scanning or while in Hold. The Chan up and Chan down keys override the Scan Rate time.
The SIG LED should not be used to detect pulses while in the Aerial Mode. The DSP requires 2 pulses to verify a
signal. The first pulse heard will not be shown with a flashing LED, only the second pulse and all other consecutive
pulses will have an LED flash corresponding to a detected pulse. While Aerial scanning, usually there is not
enough time for 2 pulses to appear when scanning. Only when Hold is used or a long enough scan rate is used,
will there be enough time for multiple pulses and for the SIG LED to flash for every detected pulse.
14.0 Setting Stationary Time Out
The DSP needs two pulses to verify 1 pulse, therefore the minimum stationary Time Out time must be set to allow
for at least 2 pulses from the transmitter with the longest pulse repetition period to be detected. Using the example
above, a 45 ppm transmitter will have a period length of 2.66 seconds for two consecutive pulses.
Thus, for the 45 ppm transmitter, the minimum Time Out time will need to be set for 3 seconds for the R4500S to
detect the presence of a transmitter. Once a pulse is verified, a signal is sent to the R4500S indicating a pulse is
present. This will also correspond with the SIG LED flashing for every valid pulse detected. Once a valid pulse is
present, the Scan Time will override the Time Out. If two consecutive pulses are not allowed to be detected, the
first pulse could be heard but no signal will be sent to indicate a valid pulse has been detected. The Time Out will
expire and the next frequency in the table will be scanned.
The Time Out can be set for longer than the recommended minimum setting. Setting the right Time Out will
depend on the size of the frequency table, and how quickly the table should be cycled through.
15.0 Setting Stationary Scan Time
The minimum stationary Scan Time should be set to allow for at least 5 pulses from the transmitter with the longest
pulse repetition period to be detected.
Once a valid signal has been detected during a Time Out period, the Time Out time is overridden by the Scan
Time. The Scan Time is the length of time to attempt to detect a valid pulse rate. The R4500S uses a pattern
matching algorithm to verify a pulse rate. The pattern matching algorithm uses 4 valid consecutive pulses and the
entered pulse rate information to verify a pulse rate. A setting for 5 consecutive pulses is needed because the first
pulse is not used. The Scan Time should be greater than the minimum setting to help allow for filtering out false
detections. Noise can trigger a false pulse rate. With a longer Scan Time, the number of detected pulses for a
transmitter located in the area will be greater, and separating a valid pulse rate stored to memory from a noise
generated pulse rate stored to memory will be easier.

17.0 Charging the Batteries
The R4500S is using NiMH (Nickel Metal Hydride) batteries. The capacity of the battery pack is 4.0 Amp hours.
The R4500S will operate from internal batteries for approximately 18 hours for stationary mode, and approximately
11 hours for manual and aerial modes while using the GPS.
The batteries can self drain to 80% capacity during a 6 month shelf life.
It is recommended to maintain a charge cycle when storing the receiver for long periods of time. If the charge
capacity of the batteries does not seem to be at full capacity, a couple charge cycles can bring the battery pack
back to full capacity (discharge – charge – discharge – charge)
The charger supplied with the R4500S is a “smart charger”. There is a thermal sensor to detect a full charge, and
to shutdown the charge process if the battery pack overheats.
Turn OFF the power to the R4500S when charging the batteries.
When the charger is connected to the R4500S, the charging sequence will start.
A fully depleted battery pack should be charged to full capacity within 5 hours.
