1. Introduction
The I-7188XB(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-7188XB(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-7188XB(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-7188XB(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 7188XB 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 7188XB
folder should be as follows:
7188XB
Demo Demo programs for the I-7188XB(D)
BC_TC Demo programs for the BC++ and the TC++
compiler
MSC Demo programs for the MSC compiler
7188XB_DemoList.htm Demo list for the I-7188XB(D)
Document Documents related to the I-7188XB(D)
OS_image The MiniOS7 image file matches the demo
programs
Readme.html The detailed description about the 7188XB
folder
Note: The 7188xw .exe file is used as a bridge between the I-7188XB(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.

2.2 Connect the Download Cable to the Host PC
Step 1: Connect the CA0910 download cable between COM1 of the
I-7188XB(D) and the COM Port of the Host PC, as shown in the
diagram below.
Step 2: Apply power (Vs+, GND) to the I-7188XB(D). Vs+ can be in a
range from +10V to +30V DC.

2.3 Downloading Programs to the I-7188XB(D)
Before using the MiniOS7 Utility, ensure that the download cable is
connected from the Host PC to the I-7188XB(D) and ensure that no
other programs are running on the I-7188XB(D). For details of how to
connect between the I-7188XB(D) and COM1 on the Host PC, refer to
the wiring diagram in the Sec.1.4.5---Program download.
Note: Instead of using the MiniOS7 Utility to download programs to the
I-7188XB(D), the 7188xw.exe file can also be used. Refer to Appendix
B: MiniOS7 Utility and 7188XW for details of the program download
procedure for 7188xw.exe.
The program download procedure is as follows (Refer to Sec2.1 to
install MiniOS7 Utility Ver 3.11):
Step 1: From the Windows START menu, go to
Programs/ICPDAS/MiniOS7 Utility Ver 3.11/and locate the
MiniOS7 Utility Ver3.11.
Step 2: Press and Select “New connection”. Choose the
right COM port and set other parameters. Click OK button and
the utility will search module automatically.

3.2 Compiler and Linker
A C Language compiler must be used to develop any applications. Valid
compilers include:
BC++ 3.1~5.02
TC++ 1.01
TC 2.01
MSC
MSVC++ (Prior to version 1.52).
ICP DAS suggests that BC 3.1 is used as the compiler as the libraries
provided have been created using the BC 3.1 compiler. Special
attention should be paid to the following items before using the compiler
to develop custom applications:
Generate a standard DOS executable program.
Set the CPU to 80188/80186
Set the floating point to EMULATION if floating point computation
is required. (Make sure not to choose 8087)
Cancel the Debug Information function as this helps to reduce
program size. (MiniOS7 supports this feature.)
