    Important Notice: Before using the Starterkit MBa6x or parts of the schematics of the MBa6x, you must evaluate it and determine if it is suitable for your intended application. You assume all risks and liability associated with such use. TQ-Systems GmbH makes no other warranties including, but not limited to, any implied warranty of merchantability or fitness for a particular purpose.

  • Page 9: Tips On Safety

    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.

  • Page 10: Naming Of Signals

    User's Manual l MBa6x UM 0203 l © 2024, TQ-Systems GmbH Page 3 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.
