1. Introduction
The I-7188XBD-CAN series PACs (Programmable Automation Controller) are powered
by 80188-40 processor with 512K bytes of static RAM, and 512K bytes of Flash
memory. All of them provide several communication interfaces to adapt to various
applications, such as CAN port, RS-232 port and RS-485 port. Uses can program their
application program flexibly with C/C++ language because of the built-in MiniOS7
operation system. Besides, the I-7188XBD-CAN series PACs have different I/O types
for users to match their requirement. For I-7188XBD-CAN, it provides 1 open collector
digital output channel and 1 digital input channel. It is useful for transfer the command
from differential communication interface. Therefore, it can satisfy the applications with
I/O demand. Therefore, the I-7188XBD-CAN series PACs are economic and convenient
solution for diversification CAN application.

2. Terminal Resistor Jumper Selection
Remove the cover of the I-7188XBD-CAN/μPAC-7186EXD-CAN. Users can see the
part of internal structure shown as following figure. The XC100 provides users one
jumper-selected termination resistor (J3). Its position is displayed below.
The jumper J3 is used to judge the resister of CAN network. When users want to set the
jumper JP3, the upper cover of I-7188XBD-CAN/ μPAC-7186EXD-CAN needs to be
removed. About the J3 jumper setting, please refer the following figure

3 . Wiring Diagram For Different Application
If users want to download users’ program, the following structure may be needed. Users
must use the download cable (packaged with I-7188XBD-CAN) to connect the I-
7188XBD-CAN COM1 with PC available COM port. Then, use the tool, 7188xw.exe, in
OSImage folder to download users’ program. Please refer section 4 of user manual for
more detail information.
The following figure shows the wiring diagram for general application. When the COM1
of I-7188XBD-CAN is used, sending data to COM1 will transmit the data both on RS-
232 and RS-485 port. One of the RS-232 and RS-485 port receives the data, these data
will be obtained by COM1 of the I-7188XBD-CAN. Therefore, it is not recommend using
both RS-232 and RS-485 functions of COM1 at the same time. If users select the RS-
232 function of COM1, the RTS1 and CTS1 pins are not always necessary. It is need to
check if the connection target machine uses 3-line RS-232 communication or 5-line RS-
232 communication.

Moreover, in order to wire conveniently, the I-7188XBD-CAN provides not only one CAN port, but also
another bypass CAN port. There two CAN ports are the same one. The bypass CAN port is just for wiring
with another CAN device conveniently, it doesn’t have any other function.
The general wire connection methods for DI channel of I-7188XBD-CAN are shown below.
