Introduction
Thank you for purchasing Avisoft UltraSoundGate 116Hm This
bus-powered USB device supports single-channel high-speed data
acquisition at sampling rates of up to 1 MHz
The accompanying recording software Avisoft-RECORDER USGH
provides either continuous or triggered direct-to-disk recording with
real-time spectrogram displays
Getting started
The supplied RECORDER USGH software can be launched from
Start / All Programs / Avisoft Bioacoustics / ECO DE USGH
On the first program start, the configuration dialog box will be
launched automatically (otherwise it is available from Options /
Configuration). Select the desired Sampling rate from the Input
Device Settings section and click at Ok. Then click at the Pause
button (Monitoring/Pause) and the Start button (Monitoring/Start)
You will then see the real-time spectrogram displaying the incoming
signals

1 XL input connector
The 5-pole XLR input connector represents the analog inputs of the
recording device and provide power supply voltages for external
amplifiers and microphones The connector scheme is as follows:
2 SYNC input/output
This socket allows to synchronize the sample clock signals of several
UltraSoundGate units To accomplish this, all devices must be
connected to a single computer and one device must be configured
as the master (see section RECORDER USGH Settings for details)
3 T IGGE input/output
This 2-pole (mono) 2 5 mm mini-jack connector is electrically
connected to the TRG button (7) and allows connecting an external
trigger This input is TTL-compatible (there is additionally an internal
pull-up resistor of 10 kOhm to Vcc) Pulling this input to ground (for
instance by closing a simple switch) will activate the logic USG TRG
button. See the last page on how to congigure the TRIGGER socket
as an output

This 2-pole 2 5mm mini-jack connector allows to connect an external
digital signal The input is TTL-compatible (internal pull-up resistor of
10 kOhm to Vcc) The status of this signal is stored in the LSB (bit 0)
of the 16-bit data words that are transmitted over the USB and can be
used as a sample-precise trigger source in the RECORDER software
It can be extracted afterwards by the Avisoft-SASLab Pro sound
analysis software (e g for creating labels) The digital input
functionality is not available in the 8-bit recording mode
5 PHONES
This stereo 3 5mm mini jack connector allows to connect headphones
or a small speaker for acoustically monitoring the incoming
ultrasounds A undersampling technique is being used to convert the
ultrasonic sounds into audible signals The undersampling ratio can be
adjusted from the Advanced USGH Settings dialog box of the
RECORDER USGH software (see section RECORDER USGH
Settings for details)
6 T IGGE button
This button can control the wav file recording process in the
RECORDER software To enable this mode of operation, one of the
following Trigger source options must be selected from the
configuration dialog box:
USG T G button auto hold : Pressing the button for more than 2 seconds will
activate an auto hold mechanism (the recording continues after releasing the button and
will stop once the button is pressed again) If the button is pressed for less than two
seconds, it will only record as long as the button is being pressed
USG T G button : The software will record as long as the button is pressed
USG T G button inversed : The software will record as long as the button is not
pressed (or as long as the external TRG signal is not active (logic high))
USG T G button toggled : The software will start recording once the button is
pressed and continues until the button is pressed again
7 EC indicator
This amber colored LED will flash once the device is connected to the
PC It will be switched off once the RECORDER USGH software is
running the in the monitoring mode In this mode, the REC LED
indicates whether the RECORDER software is recording the incoming
data onto disk
8 Peak level meter
The peak level meter indicates the instantaneous recording level The
red OVER LED indicates clipping (over-modulation) If this happens,
the gain should be reduced by turning the gain control knob to the left
(anticlockwise)
9 POWE indicator
This green LED indicates that the unit is connected to the USB power
supply
10 GAIN control knob
This control knob adjusts the analog input recording level
11 VOLUME control knob
This knob adjusts the volume of the phones monitor output (5)
12 USB 2.0 interface
The supplied USB cable with the push-pull plug must be plugged in
here The USB cable should be first connected to the UltraSoundGate
116Hm and then to the computer Make sure that the red dots on the
LEMO socket and the plug are aligned Otherwise the device can be
damaged It is also recommended to leave the USB cable connected
to the UltraSoundGate when it is not in use

Installation procedure
First download and install the RECORDER USGH software from the
Avisoft Bioacoustics website (www avisoft com/downloads htm or
directly www avisoft com/RECORDER USGH exe) This installation
program will install both the RECORDER USGH application
(rec_usgh exe) and the required device drivers (usgh_xx16h inf,
usgh sys) for the UltraSoundGate xx16H devices When the
installation procedure has completed, the UltraSoundGate unit can
be connected to the computer The device should then be detected
as “Avisoft-UltraSoundGate 116H” and the pre-installed driver
should be finally activated
Under some circumstances it might happen that the silent
installation of the device driver fails If that happens, navigate to the
Windows Control Panel > Hardware and Sound > Device Manager
and right-click at the entry Other devices > visoft UltraSoundGate
116H and select the Update Driver Software.. option Then click at
Browse my computer for device driver software, click at Browse and
navigate to the folder C:\Program Files (x86)\ visoft
Bioacoustics\RECORDER USGH\Drivers and finally click at Next

Setting in this guide

ECO DE USGH Settings
User's Guide Model 116Hm
The configuration dialog box can be launched from the menu
Options/Configuration or through the button
The input sample rate can be selected from the Input Device
Setting section Available sample rates are 1000, 750, 666,
500, 375, 400, 333, 300, 250, 214, 200, 187, 166, 150, 125,
100, 75, 62 and 50 kHz
The Buffer setting determines the USB transfer buffer size on
the PC Shorter durations will provide low real-time
spectrogram display latencies but might lead to erroneous
USB transfers under certain conditions
Enable band-pass mode At a few sample rates (50, 62 5, 75, 150,
187 5, 200, 250, 333 and 375 kHz), the A/D converter can be
configured for a special band-pass mode in which the analog input
bandwidth ranges from fs/2 to fs instead of the normal mode from 0
to fs/2 This option can be advantageous for monitoring applications
that require minimal WAV files sizes Note that the frequency scale
of the resulting WAV files will be reversed
Turn on the polarization voltage This option activates the internal
200V polarization voltage generator of the UltraSoundGate XX16H
devices and must be activated when using the CM16/CMPA
microphones
Ignore GetOverlapped esult error By default, the GetOverlapped
Result error message will stop the monitoring/recording process If
this option is activated, the monitoring procedure will be immediately
restarted, which is desired in long-term monitoring applications
T G out mode This option allows to change the I/O direction of the
TRG socket If activated, the TRG socket will be configured as a
digital output that carries the state of the internal trigger or file
saving state as selected from the Control Output settings dialog box
(Ctrl Out... button) In this case, the USG TRG button trigger source
options will not work The TRG out mode option is only available on
units that have the firmware version 1 1 or higher
Monitor undersampling ratio This list box allows to select the
desired undersampling ratio of the acoustic monitoring output (5)
from 2 to 30 in steps of two The internal D/A converter will be
clocked at a rate that is equal to the selected input (A/D converter)
sample rate divided by the selected ratio The resulting output
sample rate is displayed behind the ratio (= xxx Hz) For instance, if
you have selected an input sample rate of 333333 Hz and an
undersampling ratio of 10:1, the resulting output sample rate will be
33333 Hz All input signal components above the Nyquist frequency
(half of the output sample rate = 16666 Hz) will be folded down to
the range between zero and the Nyquist frequency For instance, a
30 kHz input signal will appear at the monitor output at a frequency
of 3333 Hz
The Setting ... button in the Input Device Settings section
launches the dvanced USGH Device Settings dialog box that
provides several additional device-specific options:
:
Enable master/slave mode for synchronizing several
devices If you use more than one UltraSoundGate XX16H
device, it is possible to synchronize their A/D converter
sampling clock signals by connecting them through the SYNC
sockets and activating this option (a 3 pole cable fitted with
3 5mm phone plugs is required) In such a set-up, one device
acts as the clock master and the other devices listen to the
clock signal as slaves
Activate slave mode for this device In the master/slave
mode, one devices acts as the master and the others as
slaves So, this option must be disabled on the unit that
should act as the master and must enabled on all other slave
units (all USG XX16H devices can act either as slave or
master)
Enable low power mode The A/D converter chips can
optionally be operated in a power-saving mode that would
increase the battery life in mobile laptop-based systems The
low-power mode slightly degrades the dynamic range
performance
Sound-activated recording can be arranged by selecting the
Trigger source option level of thi channel For remote-controlled
triggering via the trigger button on the device or via the external
TRG input, one of the trigger options USG TRG button... can be
used For triggering by a TTL signal attached to DIN, select
UltraSoundGate DI
The Pre-trigger duration should be kept as short as possible Long
pre-trigger settings can lead to data transmission errors if the
sample rate and the number of channels is high
In order to simplify the operation of the Avisoft-RECORDER
software in the field, a link to ECO DE USGH may be added to
the Windows Startup folder (Start-> ll Programs->Startup)
Additionally, the Avisoft-RECORDER option Monitoring/Auto tart
should be activated This arrangement will start the monitoring
process automatically after booting the laptop (the UltraSoundGate
device must be attached to the USB port prior to booting
Windows)

Installing the GPS eceiver
The supplied USB GPS receiver allows to log the geographic
coordinates of the recorded wav files from the Avisoft-RECORDER
software
It is required to install a device driver for the GPS receiver This can
be done from the supplied NAVILOCK installationCD, from the GPS
subfolder on the Avisoft Bioacoustics CD or from the manufacturer
website www navilock com
Once the GPS receiver is connected to the PC, a new USB device
will be detected and its “USB-Serial Controller” driver should be
finally activated
The sucessfully installed driver is listed on the Ports section of the
Windows Device Manager as a “Profilic-to-serial Comm Port”:
Windows automatically assigns the GPS receiver to a virtual COM
port (COM6 in the above example)

See also the RECORDER manual or click at the Help... button to
get further information on how to set it up
The optionally availble notebook carrying frame also allows to
attach the USB GPS receiver to it, which makes the entire system
more convinient
Alternatively, a battery-powered Bluetooth GPS receiver could be
used, which would eliminate the additional cable connection The
principle of the data transfer is the same because the Bluetooth
communication is estabished through a virtual COM port
The proviously installed GPS receiver can then be selected from the
Avisoft-RECORDER command 'Option '/'GPS Setting ...'
By clicking at the Scan port ! button in the GPS receiver
communication etting section, the proper COM port settings for
the GPS receiver should be detected automatically Alternatively,
you might select the serial port communication settings (COM port
number and Boud rate) manually
The GPS data logging mechanism is activated from the option
enable GPS receiver communication at the top of the dialog box

LANC / SMPTE time code interface
The RECORDER USGH software can decode LANC and
SMPTE time code information that is fed into the
UltraSoundGate digital inputs (DIN) To enable the time
code signal detection / decoding mechanism, the option
Show time code on the Configuration dialog box must be
checked:
Once a valid LANC or SMTPE signal is detected on one of
the DIN inputs, a time code display will be launched:
In case the software cannot extract a meaningful time
stamp stream, a TC ERROR message is displayed:
Interfacing to LANC Time Code
LANC (RS232, 9600 boud) time code information was
available on a number of MiniDV (tape-based) SONY and
Canon camcorders that is no longer available on the new
file-based products The LANC signal is usually a 2 5mm
stereo TRS jack (or in newer models a 10-pin A/V terminal
jack, which requires an appropriate adapter cable) that
can be connected to a USG DIN socket by using a
custom-made interface cable that has a 3-pole 2 5 mm
TRS plug at one end (with the ring pin left unconnected )
and a 2-pole 2 5 mm TS plug at the other end Such a
cable is available from Avisoft Bioacoustics (part# 40122)
Interfacing to SMPTE Time Code
SMPTE time code signals are provided by a number of
SMPTE time code generators, such as the model HORITA
PG-2100 or TG-50/TG-50P The output signal of these
devices is an AC-coupled signal that is originally intended
for recording onto an analog audio input channel It is
therefore required to convert this AC-coupled signal to the
open-collector DIN input of the UltraSoundGate A suited
adapter cable with integrated amplifier is available from
Avisoft Bioacoustics (part# 40123 )
The recorded time code can also be played from within
the Avisoft-SASLab Pro software through a common
soundcard or audio interface, which can be set up by
activating the option File/Advanced playback
options/Route UltraSoundGate DIO track (LTC) to the right
playback channel
If activated, an UltraSoundGate DIO track containing
linear time code (LTC) will be routed to the right channel of
the playback device, which will enable synchronization
with suited video playback equipment
On multichannel wav files, the channel containing the
time code must be selected from the command
Analyze/Time axis format… (activate the option “absolute
clock time” and select “SMPTE time code on USG DI
(LSB)”) In addition to that, one of the following
“multichannel mode” (mono output) options must be
selected from the command File/Playback settings…: :”1
of N”, “SUM” or “SUM mix”

Using the acquired time code
The serial time code that is acquired by the DIN input of
the UltraSoundGate hardware is stored into the least
significant bit of the waveform data samples
This information can be accessed by the Avisoft-SASLab
Pro analysis software by selecting the options LANC
timecode on USG DI (LSB) or SMPTE timecode on
USG DI(LSB) from the main window command
Analyze/Time axis format... The time axis on both the
main and spectrogram window will then represent the
recorded time code Red-coloured ticks along the time
axis indicate the individual video frames
Note that the time code track located on the least
significant bits of the wav file will be destoyed by applying
any filter command, unles the option „keep DIO state“ is
activated
SMPTE and LANC time code can also be synthesized
by the Avisoft-SASLab Pro software and stored into the
LSB of 16 bit wav files (File > Special > UltraSoundGate DIO >
In ert time code / pul e train... or Edit > Synthe izer > In ert time
code / pul e train...) The wav files containg such a time
code track can then be played through the
UltraSoundgate Payer 116 and 216H, where the time
code signal will be available on the DOUT socket
For applications that require distributing the SMPTE time
code signal to several UltraSoundGate units, a special
Active SMPTE/SYNC distribution unit is available
(part#40124) :

Setting up the Universal
Notebook Carrying Frame
The Universal Notebook Carrying Frame allows to mount the
UltraSoundGate 116Hm, the Navilock USB GPS receiver and a
notebook computer by using the supplied Velcro tapes
Avisoft Bioacoustics will not be liable for any damages or losses
that might arise from inproperly fixed units So, make sure that the
notebook computer is fixed reliably to the frame before using it
Make sure that the velco tape is attched tightly so that the units
cannot slip out It is recommended to use a short USB cable to
connect the UltraSoundGat eunit to the laptop/netbook PC
When using the UltraSoundGate with the carrying frame, it is
recommended to add the RECORDER USGH software to the
Windows Startup folder and to activate the RECORDER software
option Monitoring/Autostart In this way, the system will be ready for
recording immediately after booting the computer
