1 XLR input connector
The 5-pole XLR input connector represents the analog inputs of the
recording device and provide pow er supply voltages f or external
amplifiers and microphones. The connector scheme is as follow s:
2 USB 2. interface
3 REC indicator
This amber colored L D w ill flash once the device is connected to
the PC. It w ill be sw itched off once the R CORD R USGH
sof tw are is running the in the monitoring mode. In this mode, the
R C L D indicates w hether the R CORD R softw are is recording
the incoming data onto disk.
4 POWER indicator
This green L D indicates that the unit is connected to the USB
pow er supply.
5 TRG button
This button can control the .w av f ile recording process in the

Introduction
Thank you for purchasing Avisof t UltraSoundGate 116Hnb. This
bus-pow ered USB device supports single-channel high-speed
data acquisition at sampling rates of up to 300 kHz.
The accompanying recording softw are Avisoft-R CORD R USGH
provides either continuous or triggered direct-to-disk recording
w ith real-time spectrogram displays.
Getting started
The supplied R CORD R USGH sof tw are can be launched from
Start / All Program s / Avisoft Bioacoustics / RECORDER
USGH. On the first program start, the configuration dialog box w ill
be launched automatically (otherw ise it is available from Options /
Configuration). Select the desired Sam pling rate from the
Input Device Se ttings section and click at Ok . Then click at the
Pause button (M onitoring/Pause ) and the Start button
(Monitoring/Start). You w ill then see the real-time spectrogram
displaying the incoming signals. For details on the operation of the
R CORD R softw are see the Avisoft-R CORD R manual and the
section RECORDER USGH Software Settings in this guide.
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.

Installation procedure
First install the R CORD R USGH sof tw are either from the supplied
sof tw are installation media (navigate to the subfolder RECORDER
USH and run se tup.exe) or from the Avisof t Bioacoustics
w ebsite (w w w .avisof t.com/dow nloads.htm or directly
w w w .avisoft.com/R CORD R USGH.exe). This installation
program w ill install both the R CORD R 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 > Avisoft
UltraSoundGate 11 H and select the Update Driver Software...
option. The click at Browse my computer for device driver software,
click at Browse and navigate to the folder C:\Program Files
(x8 )\Avisoft Bioacoustics\RECORDER USGH\Drivers and finally
click at Next. The completed device driver installation w ill then look
like this:
