1. Introduction
1.1 What is the I/O Expansion Bus?
The I-7188XA, I-7188XC, I-7188XB, I-7188XG, I-7188EX, I-
7188EG & 7521 all support I/O expansion buses. The I/O
expansion bus can be used to implement various I/O
functions such as D/I, D/O, A/D, D/A, Timer/Counter, UART,
flash memory, battery backup SRAM & other I/O functions.
Nearly all kinds of I/O functions can be implemented on this
bus.
1.2 Using I-7188 I/O Expansion Boards:
The I-7188X series can plug an I/O Expansion board inside
the main body. To install it, users have to loosen the screw
and remove the shell of I-7188XA / I-7188XC / I-7188XB / I-
7188EX / I7188XG / I7188EG. The supported I/O expansion
boards are as below. It will be more.
1.3 Overview:
Even though the 7000 family is so powerful, there are some
applications chart cannot be solved, such as:
 High speed applications
 Special hardware requirement applications
 Special software requirement applications
 Combine special hardware & software applications
So we developed an I/O expansion bus in the 7188X / 752N /
7188E family to solve all these applications above. The I/O
expansion bus can be used to implement various I/O
functions such as D/I, D/O, A/D, D/A, Timer/Counter, UART,
I/O Expansion Bus for7188X/7188E User’s Manual,Jan/2005 v1.5, 7PH-000-15---5

flash memory, battery backup SRAM & other I/O functions.
Nearly all kinds of I/O functions can be implemented in
this bus.
The I/O expansion bus includes serial & parallel interface.
The parallel interface is very similar to an ISA bus, so the
user can move the old ISA bus design to the I/O expansion
bus with very little modification. The power consumption table
is given as follows:
7188XC 7188XB / XG 7188EX / EG
CPU Module 140mA@5V 260mA@5V 290mA@5V
I/O Expansion
Board 410mA@5V 290mA@5V 260mA@5V
Total Max. 550 mA@5V 550 mA@5V 550 mA@5V
Note:
Power consumption of 7-SEG
LED is 140 mA
For example:
7188XCD=140+140=280
So I/O=550-280=270 mA max.
Note:The 7188XA(D) supports I/O expansion bus but does not support
user defined pins, so the 7188XA only supports X002, X003, X560,
X600, X601, X607, X608.
I/O Expansion Bus for7188X/7188E User’s Manual,Jan/2005 v1.5, 7PH-000-15---6

The I/O pins of serial bus are programmable. They can be
programmed as D/I, or D/O. Some pins can be configured to D/I
or D/O or timer input or timer output. There are many serial
interface devices today. The features of these serial devices are
given as follows:
 Smaller size compared to parallel devices.
 Lower cost compared to parallel devices.
 Easier to design for isolation application.
The serial interface of an I/O expansion bus can link to these
serial devices very easily. The combination of serial & parallel
interface makes the I/O expansion bus very easy & powerful for
various industry applications. These are many design examples
given in this manual and all hardware circuit & software driver
sources are OPENING for all user. From these examples, the
users can buy these examples or modify them for their special
requirements. The system design steps are given as follows:
Step 1: List all functions required.
Step 2: For all functions, go to step 3. If all functions are solved 
STOP.
Step 3: If this function can be solved by the 7000 module Go to
step 2 for next function.
Step 4: If this function can be solved by 7188X+X??? Go to step
2 for next function.
Step 5: Now user must design special hardware on the I/O
expansion bus.
Step 6: User writes their special software driver based on this new
hardware.
Step 7: Refer to “7521/7522/7523/24/27 Software User’s manual”
for firmware. Modify & download this firmware into the CPU
module, this module now will work as a customized 7000
module.
Step 8: Go to step 2 for next function.
After the above steps, user can combine the standard-7000
modules & customized-7000 modules to solve all applications
in the same RS-485 network. This customized solution diagram is
given as follows:

The design of a I/O Expansion Bus make the idea of
a“Customized-7000 Module” come true. The features of
a“Customized-7000 Module” are given as follows:
 7188X+X??? Single module solution “Customized-
7000 Module”
 7000 compatible command sets & RS-485 networking
 Easy hardware/software interface for users to design &
manufacture their special hardware & software
 Time-to-market ODM solution for user’s special
requirements (any high speed, complex or combined
functions of D/I/O, A/D, D/A, ….., etc.)
 Robust, stable, flexible, time-to-market & cost-effective
total solution.

1.4 Reconfiguring the 7188XC(D)/7521(D)
From pin-4 to pin-8 of the 7188XC(D)/7521(D) there are three D/O &
two D/I pins. For the application of “Customized 7000 Modules”, these
5 D/I/O pins can be hardware reconfigured to other functions as
follows:
Step 1: Remove the reconfiguration-resistor as follows:
If DO3 is reconfigured, remove R19
If DO2 is reconfigured, remove R20
If DO1 is reconfigured, remove R21
If DI3 is reconfigured, remove R22
If DI2 is reconfigured, remove R23
Then, the onboard D/I/O functions can be disabled.
Step 2: Install a 5-pin male reconfiguration-jumper into the TP0 of the
7188XC(D)/7521(D)
Step 3: Design a 5-pin female reconfiguration-jumper in X??? for
Connection to TP1. Then the external signals from pin-4 to
pin-8 can be connected to X???. The user can refigure these
5 D/I/O pins to their special requirements now.
Note: If the DO2 is reconfigured to D/I, its initial state must be High. If
its initial state is LOW, system clock will be reduced to 10M. So
all clock-related libraries will only be at half-speed.
Refer to next page for more information.
I/O Expansion Bus for7188X/7188E User’s Manual,Jan/2005 v1.5, 7PH-000-15---9

Example:
The X100 is an 8-channel D/I board designed for the 7188X(D) /
7521(D). It removes all 5 resistors, R19 ~ R23, and reconfigures all
these pins as D/I pins. It installs another 5-pin female reconfiguration-
jumper into TP1 of the 7188XC(D)/7521(D). Therefore, user can select
the original 3_DO_2_DI functions or new 5_DI functions by setting the
jumper in different positions.
The I-7188XB(D), I-7188XG(D), I-7188EX(D), I-7188EG(D) has 14
user-defined pins. But the I-7188XB(D), I-7188XG(D), I-7188EX(D),I-
7188EG(D) & I-7188XA(D) don’t support the reconfiguration-resistor.
So the user-defined pins of the 7188X / 7521 family are given as
follows:
Module User defined pins Reconfiguration pins Customized I/O pins
7188XA (D) 0 0 0+0=0
7188XB (D) 14 0 14+0=14
7188XC (D) 3 5 3+5=8
7188XG (D) 14 0 14+0=14
7188EX (D) 14 0 14+0=14
7188EG (D) 14 0 14+0=14
7521 (D) 3 5 3+5=8
7522 / 23 / 24 / 27 (D) 0 0 0+0=0
Note:The 7188XA(D) supports I/O expansion bus but does not support
user defined pins, so the 7188XA only supports X002, X003, X560,
X600, X601, X607, X608.
