3.2 Installing the Software
System requirements
Software: One of the following Windows operating systems is required: Windows 7, Vista
or Windows XP (English and German versions supported). Other language versions may lead
to software errors.
Hardware: USB Port 1.1
Installing the software
Please check the system requirements before you install the software. MCS cannot guarantee
that the software works properly if these requirements are not fulfilled.
Important: Please make sure that you have full control over your computer as an administrator.
Otherwise, is possible that the installed software does not work properly.
1. Double-click Setup.exe on the installation volume. The installation assistant will show up
and guide you through the installation procedure.
2. Follow the instructions of the installation assistant.
3.3 Setting Up and Connecting the PGA
Note: You can use an USB hub for connecting the PGA to the computer, for example, if you have
no free USB port or if you need to extend the USB cable. Please note that other devices that are
connected to the same USB port and that send or receive continuous data streams, for example,
a web cam or USB speakers, can hinder the transmission of the gain settings from the computer.
The following instructions refer only to the operation of the PGA. For general recommendations
on the grounding and shielding of the setup, please refer to the Miniature Preamplifier Manual.
Provide a power supply, for example PS40W, and a computer with USB 1.1 port in the immediate
vicinity of the installation site.
The recommended value of supply voltage should be U
S
=
 6.0 V. The limits for proper operation
ranges from
 5.7 V to  12.0 V. Please use the lowest possible supply voltage. The higher the
supply voltage, the more heat will be internally generated by the voltage regulators!
Note: The PGA should only be operated if the brightness of the power LEDs is stable (without
flickering), otherwise the DC shows instabilities.
+6.0 V: 4 mm red plug connector positive supply voltage
GND: 4 mm black plug connector ground
–6.0 V: 4 mm blue plug connector negative supply voltage
