Introduction:
The R4500C is a receiver - data logger combination with built in GPS. (An optional GPS antenna is required to use
the GPS feature)
Operationally, the R4500C 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 R4500C 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 R4500C. When the signal has been digitized, the DSP
processor uses internal mathematical calculations to identify signals.
The C suffix indicates the software in this receiver is programmed to detect ATS’s 100 code coded transmitters.

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 5 minutes.
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 tag location using aircraft. While scanning a table, no information will be recorded unless
Hold is activated. The Hold button is used to toggle between scanning the frequency table, and to hold the
scanning of the frequency table. When Hold is activated, the scanning of the frequency table stops and is held for
the frequency shown in the screen. In Hold, all available information will be continually stored. Tag ID, frequency,
signal strength and time are stored to memory when the operator exits Hold or activates Record. In Hold,Record
needs to be activated when no ID is detected but a Tag can be heard. Aircraft location is also recorded 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 ID, 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.

Advanced Telemetry Systems, Inc. R4500C Reference User Manual R10-12-A 9
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.

parameters during the tracking survey.
Screen 1

Advanced Telemetry Systems, Inc. R4500C Reference User Manual R10-12-A 14
Table #: Selects the frequency table used for scanning. Twelve tables are available.
Multiple tables are used to optimize Aerial surveys in multiple locations.
Scan Rate: Sets the amount of time the R4500C will stop on each frequency while attempting
to detect tags. The number after the decimal point may be a 0 or a 5 to allow half
second increments.
Time Out: The amount of time the receiver will stay on a Frequency while attempting to
detect a tag. If no tag 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 tag is detected in the Time Out period. The user
defines the parameter (e.g. 003 – 300 seconds). Refer to section 14.0 for
information on setting the Time Out value.
Screen 2
GPS: Sets whether the GPS receiver is on or off when an Aerial Scan starts. An optional
GPS antenna must be connected to the R4500C for this option to work.
2.2.2 Stationary Defaults
Move the cursor to the Stationary Defaults item and press “ENTER”. There will be a number of different screens
to go through when entering the stationary defaults, depending on your screen selections. Pressing “ESC” will bring
you back to the previous screen.
Screen 1
Time Out: The amount of time the receiver will stay on a Frequency while attempting to
detect a tag. If no tag 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 tag is detected in the Time Out period. The user
defines the parameter (e.g. 003 – 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 tags. The Scan
time will override the Time Out time, if a pulse has been detected during the Time

Advanced Telemetry Systems, Inc. R4500C Reference User Manual R10-12-A 15
Out period. The Scan Time is set to whatever you need this set at (e.g. 003 – 300)
seconds. Refer to section 15.0 for information on setting the Scan Time value.
Store Rate: This defines how often a tag’s detection will be stored for each antenna. 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 all
detected ID’s for that frequency, and the total count of detections for each ID
during the 10 minute store period.
Pressing “ENTER”while on the Store Rate setting will advance to the next screen.
Screen 2
Tables : The frequency tables you want to scan. There are twelve tables available.
Pressing “ENTER”while on the Store Rate setting will advance to the next screen.
Screen 3
Antenna # : The number of antennas the receiver will sample. This feature requires an
external antenna switchbox connected to the AUX port of the R4500C. If using a
2-way switchbox, this would be set to 2.
EXT Data XFER: This setting is set to YES when transferring recorded data every hour to another
device. This can be used for retrieving your data remotely. Two example devices
are RDP (Remote Data Platform) and GOES (Geostationary Operational
Environmental Satellites). The GOES satellite operation requires an account with
NESDIS (National Environmental Satellite, Data and Information Service). Contact
ATS for more information regarding GOES and RDPs.
Pressing “ENTER”while on the EXT Data XFER setting will advance to the next screen.

Advanced Telemetry Systems, Inc. R4500C Reference User Manual R10-12-A 16
Screen 4
To activate the Reference tag feature, use the or the key. These two keys are used to toggle between
the two choices.
If you entered YES for the reference tag, you will be prompted to enter the reference tag frequency, and the store
rate of the reference tag.
Screen 5
Reference Freq: This is the frequency of a radio tag 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
ID detection.
Note: There is a limit on the number of reference transmitter points that can be
collected during each storage period. The maximum number is 16 (I.E. The
number of collocated codes on the reference frequency times one plus the number
of antennas should not be greater than 16).

For this example there were 2 antennas selected and 10 reference transmitters.
The reference transmitter codes were 6, 9, 15, 18, 42, 71, 78, 79, 86. There should
have been 30 data points if all the transmitters had been picked up for each
antenna during this store period. Instead the data shows detections for all the
reference transmitters shown for antenna 0, only 6 shown for antenna 1 and none
shown for antenna 2. The maximum number of reference transmitters that can be
used when switching between two antennas is five
Store Rate: This defines how frequently the data from the reference transmitter will be stored.
A count of the number of detected tag ID’s will be stored for the entire store rate.
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 tag. This is true even if the animal data were collected at
6:30 am and the reference data were collected at 6:00 am.
2.3 Stat Hold (Stationary 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 R4500C 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”.
2.4 Channel Delay
During a stationary scan, when switching to a new frequency the “Channel Delay“ will be activated. The available
delay time is 0-5000 milliseconds. The default Channel Delay time is 1000 milliseconds (1 second). The purpose of
the Channel Delay is to filter out unwanted noise pulses when switching frequencies. The R4500C filters out
unwanted noise pulses during the Channel 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 Channel Delay time has expired.
This adjust is available for cases where the noise level changes significantly when frequency channels are
changed. The R4500C 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

Advanced Telemetry Systems, Inc. R4500C Reference User Manual R10-12-A 18
antennas on several or all frequency channels even with no signal present; you may want to increase the Channel
Delay time. If noise pulses are present, and the multiple antenna scanning sequence does not start, the Channel
Delay time is set correctly.
Setting the Channel Delay time longer gives more time for the R4500C 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 R4500C 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 Channel 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: Channel Delay time + Time Out of
antenna 0 = 1 + 3 = 4 seconds. For the10 frequencies the total scan time would be 40 seconds. With the Channel
Delay set correctly, scan times can be reduced by allowing time for the R4500C 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”.
2.5 Ext Data
This optional feature is used when you want to dump data out hourly through a serial port to another device. This
screen is used to select the type of device you want to dump to. For this feature to be activated it will need to have
been selected for in screen 6 of the Stationary Setup.
Enter a 1 or 2 for the type of device and press “ENTER”.
2.5.1 RDP – Remote Data Platform

Advanced Telemetry Systems, Inc. R4500C Reference User Manual R10-12-A 19
With this setting selected all the data collected during the hour will be dumped out the PC/CLONE serial port as
binary compressed data.
Screen 2
9600 : Sets the serial communication settings for the R4500C’s data output to
“baud: 9600, no parity, 8 data bits, 1 stop bit”.
57600: Sets the serial communication settings for the R4500C’s data output to
“baud: 57600, no parity, 8 data bits, 1 stop bit”.
Enter a 1 or 2 for the desired serial port settings and press “ENTER”. The screen will return to the “Setup Menu”
2.5.2 Goes – Geostationary Operational Environmental Satellites
With this setting selected, limited amounts of data collected during the hour will be dumped out the PC/CLONE and
AUX serial ports as binary compressed data.
The GOES functionality enables the receiver to send data to a geostationary satellite so that the user can retrieve it
later from another location. This system has the advantage of working in remote locations not typically covered by
standard cell phone service providers.
To use GOES you first need an account with NESDIS (National Environmental Satellite, Data and Information
Service). You also need a GOES Transmitter. Both the SAT HDR GOES and TX312 models sold by Campbell
Scientific, Inc are compatible with the data protocol being sent out the AUX serial port. The data coming out the
PC/CLONE port is standard RS232 with settings: “baud: 9600, no parity, 8 data bits, 1 stop bit”.
Screen 2
1200: Informs the R4500C that the GOES satellite will be transmitting data back to Earth
at 1200 baud. This value is assigned by NESDIS (National Environmental Satellite,
Data and Information Service).
300: Informs the R4500C that the GOES satellite will be transmitting data back to Earth
at 300 baud. This value is assigned by NESDIS (National Environmental Satellite,
Data and Information Service).
N/A: Informs the R4500C that it doesn’t need to worry about the GOES transmission
rate. You would select this if you wanted to take advantage of the GOES data
format without actually using the GOES transmitter and setup.

Enter the value of the transmit window size assigned by NESDIS and press “ENTER”.
Screens 2 and 3 are used to limit the amount of data dumped out the serial port. The data size will be a size that
can be handled by hourly satellite transmissions. Data that doesn’t get sent to the GOES transmitter this hour will
be saved for the next hours dump. If you anticipate having intervals where you collect more data than can be sent
by a satellite transmission, you will need to make sure you have intervals where you collect limited data so the
system can catch up.

This optional feature allows you to select what type of transmitter type you will be monitoring.
Unless this selection is changed the default will be Coded. To select move the cursor to select either Codedl or
Coded with Data and press “ENTER.
The with data is used when you want to use tags that have a few extra pulses in their code that translate to some
data from some measurement the tag is designed to take such as temperature. The coded pulse stream is decoded
into a Tx Id, data type and period. The period can be then plugged into an equation such as a quadratic to give the
measurement of interest.
