2 Introduction
Thank you for choosing the MicroSys SBC-LX2160A Single Board Computer
system. This manual should help you to get the best performance and details out
all of its features.
2.1 Safety and Handling Precautions
ALWAYS use the correct type and polarity of the power supply!
DO NOT exceed the rated maximum values for the power
supply! This may result in severe permanent damage to the
unit, as well as possible serious injury.
ALWAYS keep the unit dry, clean and free of foreign objects.
Otherwise, irreparable damage may occur.
Parts of the unit may become hot during operation. Take care
not to touch any parts of the circuitry during operation to avoid
burns, and operate the unit in a well-ventilated location.
Provide an appropriate cooling solution as required.
ALWAYS take care of ESD-safe handling!
Many pins on external connectors are directly connected to the
CPU or other ESD sensitive devices.
Make or break ANY connections ONLY while the unit is
switched OFF.
Otherwise, permanent damage to the unit may occur, which is
not covered by warranty.
There is no separate SHIELD connection.
All the metal sheaths of shielded connectors are connected to
GND.
Also, all mounting holes of the carrier board are connected to
GND.
The module’s mounting holes are not connected to GND
Take this into account when handling and mounting the unit.
DO NOT REMOVE THE MODULE FROM THE CRX-08 CARRRIER
UNLESS INSTRUCTED BY MICROSYS.
IF THE MODULE NEEDS TO BE REMOVED, USE EXTREME
CARE AND ONLY EXERCISE EQUAL FORCE / PRESSURE ON
THE BOARD-TO-BOARD CONNECTORS. DO NOT TILT / SHIFT
THE MODULE DURING MATING OR REMOVAL.

3 Quick Start Guide
3.1 Prerequisites
Always make sure to handle the SBC-LX2160A unit ESD-safe!
Otherwise, the unit may suffer permanent damage.
However, do not place the unit directly flat on a metal surface,
as this may result in short circuits and damage to the board.
After unpacking the unit, make sure that is clean and free of visible damage or foreign
objects.
3.1.1 Minimum Required Items
To operate the board, you will at least need the following items:
■an adequate ATX power supply, delivering 200W minimum.
■an USB cable (type A –mini B) adapted to connector ST29
■a serial terminal, such as a PC with an USB port running a terminal Software
(e.g. TeraTerm, HyperTerminal, putty, ckermit...), or else a hardware serial
console. Choose the following parameters:
(a) 115200 Bd
(b) 8 Data bits
(c) No parity
(d) 1 Stop Bit
3.1.2 Recommended Items
The following items are optional, but strongly recommended for practical operation
and development purposes:
■Network connection to your local network installation
■TFTP server available for downloading within the network (Hint: may run on the
same PC as the serial Terminal)
■SD card as mass storage and/or boot media

3.2 Basic Operation
3.2.1 Board Preparation and Power-Up
■Make sure the switches SW4 and SW5 are set properly in order to select the
correct boot source and board configuration. The board comes preconfigured
to boot correctly on arrival.
■Connect a mini USB cable to ST29.
■Connect other peripherals (USB, LAN ...) as intended.
■Connect the ATX power supply to the PWR connectors ST3 and ST5, while the
ATX power supply is still switched off.
■Make sure a jumper is placed on ST4 (DCDC_ON) to enable all dc/dc on
carrier
■Make sure a jumper is placed on ST49 (ON/OFF-switch) to switch the carrier
board ON
■Enable the ATX power supply via its On/Off switch, located near the AC input.
After Power-up, the green LEDs on the carrier and the module
should light up and the red LEDs should be off.
IF NOT, DISCONNECT THE UNIT FROM POWER AND CHECK
FOR FAULTS!

For detailed setup instructions and general information on the board support pack-
age, refer to “Linux_QorIQ_Yocto_SDK_User_Manual”.
3.2.4 Power-Down
To power doen the complete system switch off the ATX-power supply.
Removing ST49 will power down just the carrier. The modul is not powered down
by ST49. The module is just forced to RESET.
3.2.5 Reset
Pressing the SW2 switch will force a RESET to carrier and module.
RESET will also occure if one oft he carrier voltages is no in defined range. (12V,
2V5, 1V8, 1V5, 5V0, 1V3, 1V1, 0V88)
