1 Overview
1.1 Introduction
The EXP-ISO-COM8 is an Add-on Module conforming to the EPIC Express Specification. It comprises eight
independent serial ports with RS232 / RS422 / RS485 standards.
Especially for the embedded market all interfaces are galvanic isolated that external distortions cannot
damage the whole Module as well as the CPU board. The galvanic isolation is a good solution for potential
differences with interconnections.
The EXP-ISO-COM8 supports Stack-up and Stack-down to a CPU Module.
The different modes RS232/RS485 for the serial transceivers can be selected by setting a 2.00 mm jumper close
to each interface. The same can be done with termination resistors for RS422 / RS485 mode. Four serial ports
can be found at the front in form of DSUB-9 connectors. The other four are available on IDC10 pin headers.
Furthermore the EXP-ISO-COM8 runs out of a single 5 Volts power supply coming from the PCI/104 Express
connector. All other voltages are generated on the board itself.
The EXP-ISO-COM8 runs with Linux and Windows XP operation systems.

Note: It is strongly recommend using plastic spacers instead of metal spacers to mount
the board. With metal spacers, there is a possible danger to create a short circuit
with the components located around the mounting holes.
This can damage the board!
