Product Safety
Product Safety
Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive devices.
Electrostatic discharge (ESD) can damage components. To protect the PCB
and other components against damage from static electricity, you should
follow some precautions whenever you work on your computer.
Power down and unplug your computer system when working on the
inside.
Hold components by the edges and try not to touch the IC chips, leads,
or circuitry.
Use a grounded wrist strap before handling computer components.
Place components on a grounded antistatic pad or on the bag that came
with the component whenever the components are separated from the
system.
Only store the product in its original ESD-protected packaging. Retain
the original packaging in case you need to return the product to MEN for
repair.

Conformity
MEN products are no ready-made products for end users. They are tested according to
the standards given in the Technical Data and thus enable you to achieve certification of
the product according to the standards applicable in your field of application.
RoHS
Since July 1, 2006 all MEN standard products comply with RoHS legislation.
Since January 2005 the SMD and manual soldering processes at MEN have already been
completely lead-free. Between June 2004 and June 30, 2006 MEN’s selected component
suppliers have changed delivery to RoHS-compliant parts. During this period any change
and status was traceable through the MEN ERP system and the boards gradually became
RoHS-compliant.
WEEE Application
Nevertheless, MEN is registered as a manufacturer in Germany. The registration number
can be provided on request.
Copyright © 2018 MEN Holding. All rights reserved.
The WEEE directive does not apply to fixed industrial plants and tools. The
compliance is the responsibility of the company which puts the product
on the market, as defined in the directive; components and sub-
assemblies are not subject to product compliance.
In other words: Since MEN does not deliver ready-made products to end
users, the WEEE directive is not applicable for MEN. Users are
nevertheless recommended to properly recycle all electronic boards
which have passed their life cycle.

1 Product Overview
1.1 Product Description
Analog Audio Interface
The PX5 is a PCI Express Mini Card providing an industry-grade USB HID to analog audio
interface. It supports one differential stereo audio IN and one differential stereo audio
OUT channel at line level.
Rugged Design for Rail and Aerospace
Thanks to its standardized form factor the PX5 can be used as an audio extension for
CompactPCI and CompactPCI Serial systems as well as box and panel PCs.
Its rugged and compact design makes it especially suitable for the rail and aerospace
markets, for example for ELA systems, in-flight and rolling stock entertainment systems,
cockpit-to-passenger communication in planes, inter-phone or intercom systems.
