APx515 B Series Audio Analyzer: Installation 21
Select “Demo Mode.” APx500 will run in demo mode,
which allows you to explore the user interface but does
not enable any measurement functions. Input data shown
in Demo Mode is false data, generated for display only.
From the Instrument Type menu, select an instrument to
be emulated in Demo Mode.
Running the software with instrument
hardware attached
NOTE: You must have standard user rights or
administrator rights to operate APx500 soft-
ware. Guest users are not supported.
Connecting the instrument to your PC
Before connecting your APx515 instrument to your PC,
install the APx500 measurement software as described
above. Connecting the instrument prior to software instal-
lation may cause Windows to select an incorrect USB
driver for the instrument.
USB driver selection
The measurement software communicates with the
APx515 using a USB 2.0 interconnection. Once the soft-
ware is successfully installed, connect one end of the
USB cable to a USB 2.0 port on the PC, and the other end
to the PC INTERFACE port on the rear of the APx515.
We strongly recommend that you use the USB cable
included with your instrument (AP part number CAB-
APSI). We have tested other USB cables that perform
poorly.
Note: Some PCs have optional USB ports on
the front of the PC, or on extension brackets
on the rear. In many cases these convenience
ports have compromised performance due to
the extra cable length within the PC. We rec-
ommend using USB ports directly connected to
the PC motherboard, typically at the rear of the
PC.
Connect the APx515 mains power cord to the instrument
and to a source of ac mains power. See Connecting your
instrument to the electrical mains supply below for
more information about mains connections.
Turn the instrument on by rocking the mains power
switch up to ON ( | ). The mains power switch is located
in the power entry module on the rear of the APx515.
Windows will detect the presence of the APx515 on the
USB port and will open the Hardware Update Wizard to
search for the correct software driver. Select “Install the
software automatically.” Windows will find the Audio
Precision driver software installed with APx500 and con-
nect to the APx515.
Launch APx500 by double-clicking on the installed
shortcut. With the APx515 connected, you may be asked
to update the instrument firmware during the first launch
of the measurement software. APx500 will start, and in a
short time you will be presented with the opening screen.
Refer to the APx500 User’s Manual for more informa-
tion about making measurements.
