D500X USER`S MANUAL - Bat Conservation and Management

D500X USER`S MANUAL - Bat Conservation and Management
Firmware version 2.0.7
The D 500X is an ultrasound recording unit intended for long-term, unattended recording of
bat calls. The recorder is equipped with four slots for CF cards. The triggering system allows
the device to start recording as a sound is detected. The recording length can be selected in
steps from 0.3 up to 20 seconds. In order not to fill the card too fast at locations with high
activity, a minimum time between two recordings can be applied. The recorder is normally
operated in a low-power mode with no pre-trigger (i.e. the recording starts as the sound
exceeds the chosen threshold level), but both pre-and post-trigger functions are available in
the standard (not low-power) mode.
Some of the features of the D500X are:
Built-in electret microphone
Jack for external microphone
Powered either from 4 AA cells (internal) or external batteries/power supply
Timer to turn the unit on/off at desired intervals
Weather-protected housing (built-in microphone requires some protection)
Size: 165 x 170 x 53 mm, rugged aluminium housing
Sampling rates: 44.1 kHz, 300 kHz and 500 kHz (optimized for 500 kHz)
ADC resolution: 16 bits
Selectable high-pass filter to attenuate low frequency signals
Optional external trigger input jack
Time/date stamped sound files

Powering the D500X
The D500X can be powered either from internal batteries or from external batteries/power
supply. In the case of internal batteries, 4 AA cells are used. Alkaline batteries or
rechargeable NiMH cells are recommended – please note the polarity as indicated in the
battery holders!
An external battery of 4.5-8 V DC can also be connected to the DC jack using a cable
available from Pettersson. The Main Power switch on the front panel is used to select internal
or external supply. Setting it to the mid position turns off both the internal and external
To switch the unit on, press the ON/OFF key briefly and then press/hold it for a few seconds.
To turn it off press the ON/OFF key and confirm by pressing the ENTER key as shown on the
display. The detector will be turned on without using the ON/OFF key when the Main Power
switch is activated.
In order to constantly maintain power to the real-time clock and some other parts of the
detector, a small lithium battery is incorporated in the detector. After several years of use, this
battery has to be replaced. Please contact Pettersson for more information about this.
Caution. Carefully note the polarity of the batteries and/or the external power
supply. Reverse polarizing the supply voltage as well as exceeding the maximum
voltage may cause permanent damage to the detector!
Battery handling precautions. Incorrect use or handling of the batteries can
cause them to leak or burst and create the danger of fire and personal injury as
well as damage to the detector.
Remove the batteries from the D500X if you do not plan to use it for more than
two weeks.
Never recharge batteries, never allow direct connection between two ends of a battery and
never try to take batteries apart.
Do not expose batteries to direct heat or dispose of them by burning. Doing so can create the
danger of explosion.
Never mix batteries of different types.
Dead batteries are susceptible to leakage, which can cause serious damage to the D500X.
Remove batteries from the detector as soon as you notice they are dead.
Using the D500X for the first time
Make sure that batteries have been installed and that at least one FAT32 formatted CF card
has been installed. The cards must be installed in the slots in rising order, starting with CF
card slot #1.
Caution. Always follow the instructions supplied with the CF card you are using.
Specifically, always switch off the power to the D500X using the INT/EXT Power
switch before removing or inserting a CF card. Never switch the power off or
plug/unplug external DC power while the D500X is accessing the CF card, i.e.
while recording, while upgrading the firmware or while the detector is booting.
Doing so can cause loss of recorded files and/or corruption of the CF card. When
the display shows READY (see picture below), it is safe to turn the power off.
Be careful not to drop any small objects in through the CF card slots. They can
cause damage to the CF card holder pins and metal objects may cause a short
circuit that can damage the detector.
To turn the detector on, set the Power switch to the INT or EXT position depending on if you
are using internal or external batteries. During start-up, status messages will be shown on the
display and a list of the installed CF cards will appear. This may take a few tens of seconds,
depending on the size and number of CF cards. Press ENTER to continue to the “D500X main
The sampling frequency, pre-trig time and
recording length is shown in the upper section.
The full profile data is displayed if the ENTER
key is pressed.
The mid section shows the currently used CF
card, file name (with the wav extension
excluded) and the remaining card space.
The lower section of the screen contains
indicators for the signal level, total remaining
CF card space (on all cards) and battery
voltage. The date and time is also shown.
To avoid distorting the signal, the level
indicator (“dB”) should be kept below
maximum (the right-most segment) by
adjusting the input gain.
First adjust the Input Gain (volume) control by pressing the left/right arrow keys. The “dB
indicator” will show the signal level. The gain should be adjusted to keep the dB indicator
below maximum reading.
The D500X can make recordings in the manual mode, in which the REC button is pressed to
start the recording or in the automatic mode, in which the detector starts recording as soon as
an ultrasound of sufficient loudness and duration is detected.
To make a “manual” recording, select one of the profiles with that recording mode, e.g.
“Profile 8”. To enter the profile selection mode, press ENTER and use the left/right arrow
keys to select the desired profile. Press ENTER again to confirm the selection. Press REC to
start recording. Pressing REC a second time will interrupt the recording. If a profile with a
predetermined recording time has been chosen, the recording will stop automatically when
this time interval has elapsed.
Usually, the D500X is used in the automatic recording mode and to test this mode, select e.g.
“Profile 2”. At least one timer has to be enabled in order for this mode to work so if this has
not already been done press F1 and “3 – TIMER ON/OFF” to do so. Please refer to the
section “Changing the settings” for more information on this. When the REC key is pressed
the Input Gain/Trig Level/Interval settings screen is shown to enable adjustment of these
settings prior to start recording. Once again, the Input Gain should be adjusted to keep the dB
indicator below its maximum reading. The Trigger Level should be set to make the detector
trigger (start recording) at the desired signal level. As an aid to do that, “***” flashes on the
row labelled “TRIG LEV” each time the input signal level reaches or exceeds the trigger
level. The “Interval” settings determines the minimum time between successive recordings.
This can be used to avoid filling the card too fast in locations with very high activity. To
accept the settings, press ENTER and the detector will begin waiting for a signal. Each time a
sufficiently loud signal appears, a recording will be made. To save power and increase battery
life time, the detector is put in a low-power “sleep mode” while waiting for a signal (this is
possible only as long as no pre-trigger is used). To exit the automatic recording mode, press
the ON/OFF key briefly once while the detector is waiting and then press/hold the ON/OFF
key until the display indicates that the detector is awake.
Changing the settings
Press the F1 key to enter the Settings menu. The settings are grouped into the following:
To select one of the categories above, move the highlighted section to the desired category
using the up/down arrow keys and press ENTER.
When the detector is turned off, it saves all of the current settings so the next time it is turned
on it will use the same settings.
Each “profile” contains the following parameters:
Sampling frequency (44.1 kHz, 300 kHz or 500 kHz)
Pre-trigger time (OFF, 0.1, 0.3, 0.5, 1 sec)
Recording length (0.3, 0.5, 1, 2, 3, 5, 10, 20 sec or Manual)
HP filter (ON/OFF)
Autorec (YES/NO)
Trigger source
Trigger sensitivity (1 Very high, 2 High, 3 Medium, 4 Low, 5 Very low)
Switching between different profiles is an easy and fast way to change the settings. The
D500X has ten fixed profiles and ten “user profiles”. To select which one of the 20 profiles to
use, press ENTER while the display shows the “READY” screen and use the left/right arrow
keys to select the desired profile. Press ENTER again to confirm the selection.
The use of the different parameters is described in more detail in the sections “Using the
D500X for automatic/manual recording”.
To edit one of the user profiles, select USER PROFILES from the F1 menu and then select
the desired profile, e.g. “USER0” using the arrow keys and press ENTER to enter the edit
mode. The highlighted parameter is changed with the left/right arrow keys. To move to the
next parameter, press the down arrow key. To accept and save the settings, press ENTER and
the detector will return to the main screen.
If Recording Length “Manual” is chosen, the recording will continue until the REC button is
pressed a second time. However, the recording time is limited to 1 hour in this recording
The high-pass (HP) filter attenuates low-frequency signals and should usually be used (ON).
It starts cutting off at around 20 kHz. To record signals with a frequency below ca. 15 kHz,
set the filter to OFF.
The trigger sensitivity (T SENS in the User Profiles menu) - not to be confused with the
trigger level – determines the requirements for the duration of the signal in order for
triggering the detector. To make the detector start recording for minimum signal duration and
level, set the trigger sensitivity to VERY HIGH and the trigger level to a low value. The
trigger level is set in the Recording settings menu.
The trigger source is normally the sound from the microphone and this is currently the only
alternative in the profiles. The external trigger signal is activated through a link in the plug
connected to the External Trig input jack.
The parameters in the recording settings menu are:
Input gain (volume)
Trigger level
Minimum time interval to the next recording
The highlighted parameter is changed with the left/right arrow keys. To move to the next
parameter, press the down arrow key. To accept and save the settings, press ENTER and the
detector will return to the main screen.
The input gain should be adjusted to keep the recording level (as shown on the dB indicator)
below the limit.
The trigger level should be adjusted to make the detector trigger (start recording) at the
desired level. To aid this adjustment, the text “***” flashes during the setup process each time
the detector is triggered.
The (minimum) time interval between successive recordings is determined by the Interval
parameter. It takes the values 0, 5, 10, 15,….., 55, 60 seconds. Using a value greater than 0
means that at least the chosen time interval will have to elapse before the next recording is
made, thus avoiding that the CF cards are filled excessively fast in situations with high sound
activity. The actual minimum time between recordings may differ somewhat from the entered
value, since there are variations in the time it takes to open and close files depending on the
number of files on the CF card.
The D500X has a timer that is used to turn off the detector for parts of the day, e.g. during
daytime. This will save battery power. Up to four on and off times can be entered. The timer
function is available only when the pretrigger function is not used (Pretrig = OFF).
When the TIMER ON/OFF settings mode is entered, a list of the four timer on/off times is
shown. If one or more of the timers are disabled, “--:--“ is shown as the time. To enable a
disabled timer, highlight the timer and press the ON/OFF key. The time will change from
“--:--“ to “00:00”. Press ENTER to change the time. Use the left/right arrow keys to move
between hour/minute and the up/down keys to change the value. To accept and save the
changes, press ENTER. If more than one timer is chosen, the time intervals of different timers
must not overlap.
The text WAITING will be shown on the display while the detector is asleep in an automatic
recording session (if the display is enabled).
To change the date and time, use the left/right arrow keys to change the value and the
up/down keys to move between the different items (year, month….). Press ENTER to save the
changes and return to the main menu.
The following parameters are available in this menu:
The MODE parameter determines in which situations the display is on. When the detector is
left unattended, there is no need to have the display on at all, while in other situations it may
be better to keep the display on at all times. The following values are available, ON, OFF,
AUTO (the display is turned off while the detector is asleep) and DIMMED (the display is
dimmed while the detector is asleep).
The TIMEOUT parameter determines the time that the display remains on after being
temporarily turned on with the ON/OFF key while the detector is in the sleep mode.
The BRIGHTNESS parameter determines the brightness of the display (00 = weakest, 255 =
Use up/down arrow keys to move between the parameter and the left/right arrow keys to
change the value.
Press enter to save and return to the main menu.
Service modes
If the ESC or REC key is pressed/held as the D500X is powered on, the unit will enter special
service modes. These modes should only be used by qualified service personnel. Entering
these modes may change the performance of the detector. If you have inadvertently entered
any of these modes, turn the detector off with the Power switch. The warranty does not cover
any problems arising from unauthorized use of these service modes.
Formatting a CF card
The D500X expects the CF cards to have a FAT32 file system with (at least) one partition. If
you are unsure about this, insert the CF card into a card reader connected to your computer,
open Windows Explorer and right-click on the drive containing the CF card. Select
“Properties” from the menu and check that “File system: FAT32” is shown.
To format a CF card, open Windows Explorer and right-click on the drive containing the CF
card. Select “Format” from the menu and select File System FAT32. You can also enter a
name for the Volume Label to describe the card.
If the CF card to be used is new or if you have encountered problems with the card, the
CF card should be formatted in a Windows PC, selecting FAT32 as file system.
Important! D500X firmware version 1 used a different method to store the files on the
CF cards, requiring the CF cards to first be “prepared” using the D500X Utility
program. The preparation stage has been eliminated in firmware version 2, so this
version only requires that the CF cards used have been FAT32 formatted as described
above. Cards to be used with firmware version 2 must not be “prepared”. A prepared
CF card will appear to have no space left to the D500X.
CF card precautions.
Always follow the instructions supplied with the CF card and any CF card reader
you are using. To read files from the CF card in your PC using a USB card
reader, insert the card in the reader and then plug the USB connector into a USB
port of the computer. To remove the CF card from the computer, use the Safely Remove
Hardware application, if the Safely Remove Hardware icon appears in the notification area
on the computer screen (click on the icon and follow the instructions).
Make sure the D500X is turned off using the INT/EXT Power switch before you insert a CF
card into the CF card slot or remove a CF card from the slot.
Never switch the power off while the D500X is accessing the CF card, i.e. while recording,
playing or formatting the CF card. Doing so can cause loss of recorded files and/or
corruption of the CF card. Make sure that the text “READY” appears on the display before
switching the power off.
Before inserting a CF card into the D500X, check that the pins of the CF card holder are not
bent or have other defects. When inserting a CF card into the D500X, make sure that the card
is oriented correctly. Make sure that the correct side of the card is facing up and that you
insert the correct side of the card into the detector. Damage to the CF card holder of the
D500X resulting from any of the above conditions is not covered by the warranty.
Static electricity, electromagnetic radiation and other electrical phenomena can cause
corruption or loss of data stored on the CF card. For this reason, you should always make
backup copies of important sound files on other media such as computer hard disk or CD.
CF card problems can usually be corrected by formatting the card. Formatting a CF card
deletes all information stored on the card, including sound files and profiles. Before
formatting a card you should copy all files you wish to keep on other media. If you plan to use
the D500X where you don’t have access to other storage devices, it is a good idea to take
along a few extra CF cards just in case you experience an unexpected CF card problem.
Formatting is recommended for any CF card that you suspect contains corrupted files or for
newly purchased CF cards.
Caution. Formatting a storage medium erases all data previously stored. Make
sure you don’t inadvertently format a card or other storage device that contains
data you wish to retain!
Using more than one CF card
The D500X can use up to four CF cards. The first card must be located in slot #1 and the next
in slot #2 etc. The CF card indicator on the display shows the remaining total space on all of
the cards. When the unit is set up for an automatic (level-triggered) recording session, all the
CF cards should be newly formatted (i.e. not contain any previous recordings).
The switching between cards is made automatically. When the remaining space on the current
card is not enough to make another recording with the current settings (sampling frequency,
file length) and the unit is used in the automatic (level-triggered) recording mode, it switches
to the next card and makes the next recording there. If the detector is used in the manual
recording mode, it is not always possible to know the recording length on beforehand. In this
case, the unit switches to the next available CF card if there is less space than 10 seconds at
the chosen sampling frequency. This means that if the remaining recording time is e.g. 15
seconds and you attempt to make a recording of 20 seconds, this recording will be interrupted.
The active CF card (the card currently used to make recordings to) is shown on the display
before the file name. The remaining space on the active CF card is shown after the file name.
Choosing CF card type
Sandisk CF cards should be used. We have successfully tested Sandisk Ultra II and Extreme
III cards in sizes up to 32 GB.
In order to make it easier to remove a CF card from the D500X, a small “handle” can be made
with a piece of tape (see the picture).
Using the D500X for automatic recording
To set up the D500X for automatic recording, start with the display in the standard mode,
showing “READY” and then follow the steps below. Steps 1-4 can be skipped if the settings
do not need to be changed.
1. Check that the date and time are correct. If not, change it in the DATE AND TIME
menu accessible by first pressing the F1 key. Press ENTER to accept the settings.
2. Set the desired Timer ON/OFF time(s) by pressing F1 and selecting “TIMER
ON/OFF”. Entering 21:00 as ON time and 03:00 as OFF time will make the detector
active between 21:00 (9 pm) and 03:00 (3 am). During other hours, the detector will be
asleep and will not respond to any sound. Please refer to the section “Changing the
settings” for detailed information about the timers. Press ENTER to accept the settings.
3. Press F1 and set the display operating mode in the DISPLAY menu. The recommended
modes for automatic recording are OFF or AUTO. OFF will keep the display off during
the entire recording session to save power. AUTO will keep the display off while the
detector is waiting for a sound and on while recording. To turn on the display
momentarily when it is off, press the ON/OFF key briefly.
4. Press ENTER to display the current profile settings. If necessary, change the active
profile by pressing the LEFT/RIGHT ARROW keys. If e.g. PROFILE2 is selected, the
display will show:
f=500 PRE=OFF LEN=3
This means that the settings are:
Sampling frequency: 500 kHz
Pre-trigger: off
Recording length for each file: 3 seconds
High-pass filter enabled
Autorecording enabled
The trigger source is the signal
The “trigger sensitivity” is very high
More information on these parameters can be found in the section “Changing the
In order to use the automatic recording mode, the profile must have “A=Y”
(Autorecording enabled).
Press ENTER again, to confirm selecting the displayed profile.
5. To start the recording session, press the REC key. This will first invoke the Recording
Settings menu. Use the up/down arrow keys to change the parameter and the left/right
arrow keys to change the values, if desired.
The input gain should be adjusted to keep the recording level (as shown on the dB
indicator) below the limit.
The trigger level should be adjusted to make the detector trigger (start recording) at the
desired level. To aid this adjustment, the text “***” flashes during the setup process each
time the detector is triggered.
The Interval setting determines the (approximate) minimum time between successive
Press ENTER to accept the recording settings. This will make the detector enter the
automatic recording mode. The REC and ON indicators will flash once every 5 seconds
while the unit is waiting for a sound. During the “Interval” time (the minimum time
between successive recordings), the indicators will flash once every second. The detector
will of course not respond to any sound as long as the current time is outside of the timer
ON/OFF interval.
6. To end the recording session, wake the detector up by first momentarily pressing the
ON/OFF key and then holding it for a few seconds. This puts the unit in the standard
mode, showing “READY” on the display. If a recording is in process, it should first be
interrupted with the ESC key. When the display shows “READY”, the power can be
turned off with the main power switch. Never turn the unit off with the Power switch
while the detector is accessing the CF card (reading and/or writing)!
The D500X can be used to make recordings either with or without pre-trig (the recording
starts before the trigger occurred). Using the detector without pre-trig (“PRE=OFF”, the
recording starts as a sound triggers it) makes the detector use much less power while waiting
for a sound and is the recommended mode for long battery life time.
For unattended recording, the recording length should not be set to “MAN” since this requires
manually pressing the REC key to interrupt the recording.
Using the D500X for manual recording
To set up the D500X for manual recording, select a profile with “AUTOREC = NO” (A = N).
To start recording, press the REC key. If a profile without pre-trig (“PRE=OFF”) is used, a
recording of the chosen length (e.g. 3 seconds if “LEN=3” was chosen) will be made. If
“LEN=MAN” was chosen in the profile, press the REC key a second time to interrupt the
If a profile with pre-trig (e.g. “PRE=1”) is used, press the REC key to start recording. The text
“BUFFERING” will be displayed until the pre-trig time has elapsed in order to fill the
memory buffer. In order to stop the recording, press the REC key again. The recording will
continue to make the total recording time equal to the chosen “LEN” value and then stop.
File management
After a recording session, the recorded files are usually transferred to another medium, e.g.
the hard disk of a computer, for storage and/or analysis. In order to use the same CF card for
new recordings with the D500X, the card should be formatted in Windows (as FAT32). This
will erase all files from the CF card.
The files are “wav” files that can be used by most sound editing software. However, due to
the high sampling frequency, the files usually cannot be replayed by common sound cards.
Using special software, such as BatSound, playback at slower speed is possible with any
sound card.
The maximum number of files for a certain recording session (using 1-4 CF cards) is 64000.
The D500X Utility
The D500X Utility software is a Windows program to facilitate the use of the CF cards with
the D500X. This program can be found on the CF card that comes with the detector. Copy it
to a suitable folder on the hard disk of the computer and double-click it to run it. It is used to:
Extract embedded information from D500X files (file date/time, firmware version etc.)
Copy and rename files with optional adding of date/time/prefix/suffix to the file name
Transfer D500X firmware upgrade files to a CF card
The first step in using the D500X Utility is to select the drive that has the CF card. This is
done in the “Select CF card” section in the D500X Utility main window. Please make sure
you select the correct drive or the following operations (including formatting) will be
performed on a disk in a drive you did not intend.
You should close any other application (e.g. Windows Explorer) using the CF card or the
D500X Utility program may not be able to access the card.
Transfer D500X firmware to CF card
This selection transfers a firmware upgrade file from the PC to the CF card in order to
upgrade the D500X firmware through a special procedure. Firmware upgrades are supplied by
Pettersson as they become available. The upgrade file should have the extension “.D500X”.
To upgrade, the firmware file should be transferred to the CF card using the Transfer function
of the D500X Utility program (copying the upgrade file to the CF card through Windows will
not work). Then put the card in slot #1 of the D500X and turn the power on with the
EXT/INT Power switch. The detector will automatically recognize the card as a “firmware
upgrade” card. Follow the instructions on the display to perform the upgrade.
Recorded data files
The Info command will display embedded information from the selected file (file name,
date/time and firmware version).
The Clean file command will remove the extra information that is stored in the file. This
information is stored at the beginning of the file and can be seen in the spectrogram or
oscillogram as a very short transient. Usually, this transient is so short that it is not noticed.
Please note that after using the Clean file command, the information erased from the file
cannot be retrieved, so it is advisable to perform this operation on a copy of the original file.
The File management command opens the File Management dialog box which gives a list of
the D500X/D1000X files in the selected drive/folder with the embedded file information:
The information in the File Management list can be exported to a tab separated text file
(“Export”). Select the desired information to export by first highlighting it. It is also possible
to press Ctrl-C to copy the highlighted section to the Windows clipboard.
The Copy & Rename function is used to copy one or more D500X files from the CF card to
the computer’s hard disk. Optionally the files can also be renamed. The Rename function can
also be used to add the time and date to the original file name. A user defined prefix and/or
suffix can be added to the original file name. Selecting multiple files, will create copies of all
files with time/date, prefix and suffix added. This is useful to add identification information
(e.g. recording location) to a group of files.
As an example, if the settings showed below are applied to the file M00667.WAV above, this
will result in a copy of the file to the file ABC2010-08-26_10_39_50_M00667DEF.WAV in
the C:/temp folder.
NOTE: Older versions of the D500X Utility also have the “Format and prepare” command.
This should only be used with D500Xs running firmware version 1. Do not use the “Format
and prepare” function on CF cards to be used with D500X firmware version 2 or
Connecting external accessories to the D500X
Cables for connecting external devices to the D500X are available from Pettersson. The
connector type is Switchcraft EN3. The illustrations below show the connectors as viewed
from the outside of the D500X housing. In order to maintain water protection when not
mated, the protection cap must be in position over each connector.
External microphone
A – Reserved
B – Ground
C – Differential signal input (+)
D – Differential signal input (-)
E – Power output from detector (+3.3V)
F – External mic select input (tie to pin B on plug to enable ext mic)
External batteries
A – Ground terminal (-)
B – Positive terminal (+), recommended voltage 4.5 – 8V
External trigger signal
A – Trigger input (triggers on “low” level, voltage range 0-3.3V)
B – Ground
C – External trig select input (tie to pin B on plug to enable external trig)
The applied voltage at the trigger input must be within 0 to +3.3V relative to
ground. No voltage may be applied to the trigger input while the detector is
powered off or damage to the detector may result.
Weather protection
The D500X comes in an enclosure which is weather protected in the meaning that it will
withstand dust and a certain degree of humidity. Heavy rain may result in water intrusion, so
under such conditions additional protection is recommended. The protection cover over the
CF card holders and power switch should be used for mechanical and weather protection.
The built-in microphone is sensitive to humidity and should always be protected from rain etc.
System requirements
In order to format and prepare the CF cards for use with the D500X as well as to access the
recorded files, a PC with Windows XP or Vista and a CF card reader are required.
