Introduction
Thank you for purchasing Avisoft UltraSoundGate 416H. This bus-
powered USB device supports 4 channel high-speed data
acquisition at sampling rates of up to 750 kHz.
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
/
RECORDER 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. For details on the operation of the RECORDER software
see the Avisoft-RECORDER manual and the section
RECORDER
USGH Software Settings
in this guide.
1 XLR input connectors
The 5-pole XLR input connectors represent the analog inputs of the
recording device and provide power supply voltages for external
amplifiers and microphones. The connector scheme is as follows:
2 USB 2.0 interface
Use this USB socket to connect the device to the computer.
3 TRIGGER 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
.

4 DIN
These 2-pole 2.5mm mini-jack connectors allow to connect
external digital signals. These inputs are 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 inputs are not available in the
8-bit recording mode.
For a reliable electrical connection, a Switchcraft 0.01” Micro Plug
(part number 850X) is recommended.
5 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 on this).
6 TRG 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 TRG 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 TRG button
: The software will record as long as the button is pressed.
USG TRG 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 TRG button toggled
: The software will start recording once the button is
pressed and continues until the button is pressed again.
7 REC 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 POWER indicator
This green LED indicates that the unit is connected to the USB
power supply.
9 GAIN control knobs
The control knobs adjust the analog input recording levels for each
channel.

Installation procedure
First install the RECORDER USGH software either from the
supplied software installation media (navigate to the subfolder
RECORDER USH
and run
setup.exe
) or 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 416H” 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
>
Avisoft UltraSoundGate
416H
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)\Avisoft
Bioacoustics\RECORDER USGH\Drivers
and finally click at Next.
The completed device driver installation will then look like this:
