needed. Users must use the download cable (packaged with I-7188XBD-CAN/
μPAC-7186EXD-CAN) to connect the I-7188XBD-CAN/ μPAC-7186EXD-CAN
COM1 with PC available COM port. Then, use the tool, 7188xw.exe, in

2.5.2 General application

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.
