1.5
Tips on safety
Improper or incorrect handling of the product can substantially reduce its life span.
1.6
Symbols and typographic conventions
Table 1: Terms and Conventions
Symbol Meaning
This symbol represents the handling of electrostatic-sensitive modules and / or components. These
components are often damaged / destroyed by the transmission of a voltage higher than about 50 V.
A human body usually only experiences electrostatic discharges above approximately 3,000 V.
This symbol indicates the possible 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 symbol indicates a possible source of danger. Acting against the procedure described can lead to
possible damage to your health and / or cause damage / destruction of the material used.
This symbol represents important details or aspects for working with TQ-products.
Command
A font with fixed-width is used to denote commands, file names, or menu items.
1.7
Handling and ESD tips
General handling of your TQ-products
The TQ-product may only be used and serviced by certified 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 beforehand
that the power supply of the system has been switched off.
Violation of this guideline may result in damage / destruction of the MBLX2160A and be 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 0101 l © 2022, TQ-Systems GmbH 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 between 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 by slashes when they are important for the wiring.
The identification of the individual functions follows the above conventions.
Example: WE2# / OE#
1.9

BRIEF DESCRIPTION
This User's Manual describes the hardware of the MBLX2160A revisions 01xx and 02xx.
The MBLX2160A is designed as a carrier board for the TQMLX2160A.
All TQMLX2160A interfaces, which can be used, are available on the MBLX2160A, thus the features of the LX2160A
can be evaluated and software development for a TQMLX2160A-based project can be started directly.
The MBLX2160A supports TQMLX2160A modules with an LX2108A, LX2120A or LX2160A CPU.
