About this Manual
This is the hardware manual for the emPC-X embedded PC.
Throughout the manual, the term emPC-X is used to identify the all systems. When required, the CPU
options are identified explicitly.
Conventions
If numbers are specified in this manual, they will be either decimal or hexadecimal. We use C-notation
to identify hexadecimal numbers (the 0x prefix).
If we refer to low active signal names, they will suffixed by a “#” character.
Some parts of the contains notices you have to observe to ensure your personal safety, or to prevent
damage to property. These are visually marked with the following alert symbols:
DANGER
Indicates that death or severe personal injury will result if proper precautions are not
taken.
WARNING
Indicates that death or severe personal injury may result if proper precautions are not
taken.
CAUTION
Indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
Indicates that damage to equipment can result if proper precautions are not taken.
Indicates information that we think you should have read to save your time by avoiding
common problems. Important suggestions that should be followed will also be marked
with this sign.
Acronyms and Abbreviations
EMC Electromagnetic capability.
ESD Electrostatic discharge.
GND System ground potential. Inside the product this is connected to the metal housing,
which might be connected to protective earth by the installation. There exist some
isolated reference grounds for communication interfaces or IO. These reference
signals are referred to as GND-x, where x indicates function.
SELV Safety extra low voltage.

1 Introduction
The emPC-X platform is a flexible computer system. It consists of one CPU board and can be
expanded with a variety of IO expansion boards. The boards are stacked together and are inserted
into a rail mounted housing. This allows flexible system building. Internal busses are documented, so
users can build application specific IO expansion boards.

The RS232 (Console) serial interface is provided by Super IO W83627 chip, hence it is a legacy
compatible serial port. The connector is a standard 9 pin D-SUB plug, but the interface is connected
with four wires only, table 7 shows the pin out.

4.2 RS232
Additional serial interfaces might be implemented by a XR16V2750 dual UART chip. This type of serial
port has proprietary implementation over the internal expansion bus. Hence it needs special software
driver. For a description of UART registers refer to the EXAR manual. The UART clock input is
14,7456MHz to allow error free generation of standard baud rates. This RS232 variant provides all 8
interface signals as shown in table 8.

In the RS485 variant, there are only the differential signals D+ and D- provided. The transceiver is
enabled to send data, when RTS# of the corresponding UART is low. Hardware can be customized to
either receive or not-receive (standard) the transmitted data on the UART’s RxD input. Ask Janz Tec
for customization regarding this option.

The bidirectional differential signals D+ and D- are provided. When the transmitter is enabled, and no
data is send (1=MARK), then D+ > D- (refer to figure 8 ).
Note that D+ corresponds to pin “A” of the transceiver chip. However, this is signal B according to the
EIA-485 or Profibus standards.
The receiver has the failsafe input feature, which ensures that no data is received when D+ and D- are
floating or are shorted (e.g. by the termination resistor).

4.5 SD Card
The optional SD card slot can be accessed from the front panel. It is protected by a cover (see figure
9).
After having removed the SD card cover, push the card to eject it.
NOTICE
Removing and installing the SD card is possible when the system is running.
However, ensure that the operating system is ready for card removal before you push the
card. Otherwise, you might lose data.
To install the SD card push it into the socket until the card locks. Then install the cover.
