About this Manual
This is the hardware manual for the emPC-A500 embedded PC. It starts with an introduction to the
emPC-A500. Then it describes the features and architecture of the emPC-A500. After that it
discusses some topics about installation of the product. The rest of the manual then covers technical
details about the emPC-A500.
For a detailed architecture description of the emPC-A500 and how to develop software for it the
System Reference Manual for A500-Platforms gives information about it.
Conventions
If numbers are specified in this manual, they will be either decimal or hexadecimal. The C-notation to
identify hexadecimal numbers (the 0x prefix) is used.
Low active signal names are suffixed by a “#” character.
Some parts of the text are important. These are visually marked with the following signs:
Indicates information that, when not fully understood or followed causes permanent
damage to the system. Before using the product this information must be read.
Indicates information that saves time by avoiding problems. Important suggestions are
also marked with this sign.
Acronyms and Abbreviations

1 Introduction
The A500-Platform is a small form factor embedded computer with a display or without. It is powered
by a Freescale i.MX515 CPU with 600MHz, and hence it is powerful enough for sophisticated
embedded applications. The i.MX515 is based on ARM Cortex-A8 Core.
It can run many commonly known operating systems (e.g. Linux, Windows-CE, VxWorks). Thus one
can migrate its existing software solutions easily.
1.1 Features
The emPC-A500 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
mount housing. This allows flexible system building. So that users are able to build application specific
IO expansion boards.

Table 1: The different variations of emPC-A500
The different variations of emPC-A500 are attained by the modular assembly. Basically there are two
types of modules. The first module is the CPU module with the listed features
•600MHz ARM Cortex-A8 CPU (i.MX515),
•256 MB DDR2-RAM,
•32kB instruction and data caches,
•Unified 256kB L2 cache
•NEON SIMD media accelerator
•Vector floating point co-processor
•2 MB FLASH (for boot loader),
•internal compact flash socket type I/II for “true-IDE mode” compatible CF cards,
•dual 10 / 100 MBit Ethernet Interface,
•dual USB 2.0 interface (480MBit/s),
•2 user programmable front panel LEDs,
•32 kB nvSRAM which does not require battery backup,
•battery buffered RTC,
•internal watchdog function,
•temperature monitoring,
•Video controller with OpenGL ES 2.0 and OpenVG 1.1 hardware accelerator,
•VGA display connector (15pin HD-DSUB ),
•Internal LVDS display interface,
•Internal expansion bus (iX-Bus) for connection with IO-boards and power supply.

The second type of module is the IO module. This module can yield the listed features
•System power supply with 9..32V DC input capability,
•Reset button and Power LED,
•2 male 9pin D-SUB connectors, which can be used by the following functional blocks:
oup to 2xCAN (isolated)
oup to 2xRS232
oup to 2xRS485 (optional isolated)
oUART ports of the CPU module (console),
•Power supply monitor.
Note that not all feature are available simultaneously, contact Janz Tec AG for the possibilities
configurations.

2 Installation
The emPC-A500 is designed as a fan less computer system. Nevertheless a certain
amount of heat is generated inside the housing. The housing transports this heat to the
environment. Caution when touching the housing, burns hazard!
To check for operation, connect serial port to the system console (9600 8N1). Apply power to the
power supply connector and view the boot messages of the emPC-A500 firmware.
If the Power LED does not lit, the input polarity might be reversed. Swap the wires and try again.
2.1 Front Panel Layout
The following figures are showing the front panels of the emPC-A500s. The differences between
emPC-A500/0, emPC-A500/1 and emPC-A500/2 are at the two 9pin D-SUBs. Depending on which
configuration the IO module has, the connectors supports CAN or RS232. Optional the serial
connector can be assembled with RS485. The emPC-A500/R3 has two additional D-SUB connectors.
All emPC-A500s have jointly a VGA connector, two USB connectors, two Ethernet connectors, the
LEDs S1 and S2, the reset-button, a power LED and a power connector which are mounted on the
CPU module. The external power supply must be connected to “+” and “-“. The additional input “S” is
the sense input of the power supply monitor. Leave open if the power supply monitor is not available.
