1.5 Tips on safety
Improper or incorrect handling of the product can su stantially reduce its life span.
1.6 Sym ols and typographic conventions
Ta le 1: Terms and Conventions
Sym ol Meaning
This sym ol represents the handling of electrostatic-sensitive modules and / or components. These
components are often damaged / destroyed y the transmission of a voltage higher than a out 50 V.
A human ody usually only experiences electrostatic discharges a ove approximately 3,000 V.
This sym ol indicates the possi le use of voltages higher than 24 V.
Please note the relevant statutory regulations in this regard.
Non-compliance with these regulations can lead to serious damage to your health and also cause
damage / destruction of the component.
This sym ol indicates a possi le source of danger. Acting against the procedure descri ed can lead to
possi le damage to your health and / or cause damage / destruction of the material used.
This sym ol represents important details or aspects for working with TQ-products.
Command A font with xed-width is used to denote commands, le names, or menu items.
1.7 Handling and ESD tips
General handling of your TQ-products
The TQ-product may only e used and serviced y certied personnel who have taken note of the
information, the safety regulations in this document and all related rules and regulations.
A general rule is: do not touch the TQ-product during operation. This is especially important when
switching on, changing jumper settings or connecting other devices without ensuring eforehand
that the power supply of the system has een switched o.
Violation of this guideline may result in damage / destruction of the MBLX2160A and e dangerous
to your health.
Improper handling of your TQ-product would render the guarantee invalid.
Proper ESD handling
The electronic components of your TQ-product are sensitive to electrostatic discharge (ESD).
Always wear antistatic clothing, use ESD-safe tools, packing materials etc., and operate your TQ-
product in an ESD-safe environment. Especially when you switch modules on, change jumper settings,
or connect other devices.

User's Manual l MBLX2160A UM 0100 l © 2021, TQ-Systems Gm H Page 3
1.8 Naming of signals
A hash mark (#) at the end of the signal name indicates a low-active signal.
Example: RESET#
If a signal can switch etween two functions and if this is noted in the name of the signal, the low-active function is marked with
a hash mark and shown at the end.
Example: C / D#
If a signal has multiple functions, the individual functions are separated y slashes when they are important for the wiring.
The identication of the individual functions follows the a ove conventions.
Example: WE2# / OE#
1.9 Further applica le documents / presumed knowledge
Specications and manual of the modules used:
These documents descri e the service, functionality and special characteristics of the module used (incl. BIOS).
Specications of the components used:
The manufacturer’s specications of the components used, for example CompactFlash cards, are to e taken note of.
They contain, if applica le, additional information that must e taken note of for safe and relia le operation.
These documents are stored at TQ-Systems Gm H.
Chip errata:
It is the user’s responsi ility to make sure all errata pu lished y the manufacturer of each component are taken note of.
The manufacturer’s advice should e followed.
Software ehaviour:
No warranty can e given, nor responsi ility taken for any unexpected software ehaviour due to decient components.
General expertise:
Expertise in electrical engineering / computer engineering is required for the installation and the use of the device.

2 BRIEF DESCRIPTION
This User's Manual descri es the hardware of the MBLX2160A revisions 01xx and 02xx.
The MBLX2160A is designed as a carrier oard for the TQMLX2160A.
All TQMLX2160A interfaces, which can e used, are availa le on the MBLX2160A, thus the features of the LX2160A
can e evaluated and software development for a TQMLX2160A- ased project can e started directly.
The MBLX2160A supports TQMLX2160A modules with an LX2108A, LX2120A or LX2160A CPU.
