1.Introduction
The I-7188XC(D) is a series of expandable embedded controllers
designed for industry applications and can be used to replace PC or
PLC devices in harsh environments. The I-7188XC(D) also has support
for an I/O expansion bus, which can be used to implement various I/O
functions, such as D/I, D/O, A/D, D/A, UART, Flash memory, battery
backup SRAM, AsicKey and other I/O functions. Most types of I/O
function can be implemented using this bus. ICP DAS offers more than
20 types of I/O Expansion Board for the I-7188XC(D), which can be
used to expand the features of the controller. Depending on the type of
embedded firmware programs that are being developed, and which I/O
Expansion Board, the I-7188XC(D) can be used as a single versatile
controller.

2.Quick Start
2.1 Software Installation
Step 1: Insert the companion CD into the CD drive.
Step 2: Copy the 7188XC folder from CD:\Napdos\7188XABC\ to the
Hard Drive of the Host PC.
Step 3: Install the MiniOS7 Utility.
Locate and execute the minios7_utility_v311.exe file from
CD:\NAPDOS\MINIOS7\UTILITY\MiniOS7_utility\ folder or
http://ftp.icpdas.com/pub/cd/8000cd/napdos/minios7/utility/minios7_
utility/
Step 4: Copy the 7188xw.exe file from the CD:\Napdos\MiniOS7\utility\
folder to the PATH directory, for example C:\Windows\.
After all the software is copied to the Host PC, the content of 7188XC
folder should be as follows:
7188XC
Demo Demo programs for the I-7188XC(D)
BC_TC Demo programs for the BC++ and the TC++
compiler
MSC Demo programs for the MSC compiler
7188XC_DemoList.htm Demo list for the I-7188XC(D)
Document Documents related to the I-7188XC(D)
OS_image The MiniOS7 image file matches the demo
programs
Readme.html The detailed description about the 7188XC
folder
Note: The 7188xw.exe file is used as a bridge between the I-7188XC(D)
and the Host PC. Therefore, the 7188xw.exe file must be copied to the
“C:\Windows\” folder to allow it to be executed from any location.
