1.6 Tips on Safety
Improper or incorrect handling of the product can substantially reduce its life span.
1.7 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, contents, file names, or menu items.
1.8 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 MB-COME6-1 module 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.

1.9 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#

. INTRODUCTION
The COM Express™ mainboard MB-COME6-1 is a carrier board for COM Express™ modules with Type 6 pinout. It can be used for
embedded computers or as evaluation platform for COM Express™ modules. In combination with a standard COM Express™
module it forms a very compact hardware kit that can be used for a freely scalable embedded PC platform thanks to its modular
design. Because of this – with uniform interfaces and mechanical dimensions – the PC system can be easily adjusted to suit the
requirements of the application. The many extension options and storage media that can be added offer a high level of flexibility
and allow functionalities and performance to be extended easily, quickly and inexpensively. Typical uses are found in embedded
server applications, PC systems for automation, visualisation and monitoring and all applications that place high demands on
quality, durability and long-term availability.

3.5.4 Gigabit Ethernet
The MB-COME6-1 supports 2 common Gigabit Ethernet ports.
The Ethernet signals of the COM Express™ connector are routed to X9.
An Intel® i210IT Ethernet controller with 10/100/1000 Mbps speed implemented on the MB-COME6-1 is connected to X8.
Table 4: Ethernet EDs
Illustration 4: RJ45 Connectors X8, X9
3.5.5 Serial Interfaces (RS232/RS422)
The MB-COME6-1 supports up to 3 serial ports:
- 2 × RS232 port (D-Sub front connector and on-board header)
- 1 × RS422 (on-board header)
The COM Express™ Specification does only provide signal definitions for RX and TX lines for the serial interface. Due to the TQ-
flexiCFG feature the serial ports can be configured to route the handshake signals to free pins on the COM Express connector.

The four COM Express™ serial signals (RX/TX) are specified to provide a protection and level shifter circuit.
The implementation of this circuit would result in a lower transfer speed on the two serial ports of the COM Express™ module.
On the MB-COME6-1 the protection circuit is removed and the serial ports provide a transfer rate of up to 115 kbaud.
The MB-COME6-1 can only be used in combination with COM Express™ modules Type 6 pinout.
1: These signals are not specified in COM Express™ specification.
These signals are only available when the TQ flexiCFG feature is available on the COM Express™ module. TQMx50UC modules support this feature.

3.5.6 VDS
The MB-COME6-1 supports an VDS interface where suitable displays can be connected directly.
There are also connectors for powering the backlight of the connected display.
The MB-COME6-1 has an on-board EDID EEPROM to store display specific timing information. This EEPROM can be programmed
with an external IC programmer. If the programmer supports a 3.3 V output voltage the MB-COME6-1 can be programmed
without any additional power supply. In this case no COM Express™ module should be connected to the carrier.

1) These pins can be used for programming the on-board EDID EEPROM. The EEPROM can be powered by the 3V3_PROG pin.
3.5.7 Mini PCIe Socket
The MB-COME6-1 is equipped with a socket to support one full size Mini PCIe card. There is also a SIM card socket for native
support of UMTS or TE Mini PCIe cards.
A half size card can be inserted into this socket by means of a mechanical adapter.
The reachable transfer rate of this interface depends mainly on the COM Express™ module used and the connected device.
