Jumper Description Status
SW1 120Ωterminator resistance of CAN port.
Enable Disable
JP1
Lock mode for resisting the noise or disturbances.
In this case, updating firmware is not allowed.
Unlock mode for updating the firmware of I-8120W.
Lock Unlock
JP2
Debug port for user-defined firmware. The I-8120W
prints the debug messages or system information
from this port. Connect this port to PC COM port.
Use 7188xw.exe to show the messages. The baud
rate is 115200 bps. You can find the 7188xw.exe in
the CD. The path is CAN/SlotModule/
I_8120W/Tools/PC
JP4
Reset mode for forcing the I-8120W into download
mode. Wiring this jumper until Tx/Rx LED and Err
LED are always ON. Then, remove the wire.
Reset Normal
3. How to Start
Step1: Set the SW1 of the I-8120W to the proper position. Generally, the both end of
CAN bus (line topology) needs 2 terminator resistance. Each of them is 120Ω.
Step2: Unlock the JP1. Generally, unlock the JP1 during developing the application.

When running the application in practice, locking the JP2 is helpful to resist the
noise and disturbances.
Step3: Connect the JP2 with PC COM port.
Step4: Set the JP4 to normal.
Step5: Plug the I-8120W in your PAC. Here, use WinPAC for the demonstration. Connect
the CAN port of the I-8120W with the CAN network. Connect the peripherals
(such as monitor, Keyboard, mouse, and Ethernet) with the WinPAC. Then, turn
on the WinPAC.
Step6: Download the I8120W_Utility.exe and the I-8120.dll into the same folder on the
WinPAC. You can use ftp or USB disk to do this. (Before using the ftp, you must
configure the ftp parameters of WinPAC by using WinPAC Utility. You can find the
shortcut on the desktop of WinPAC.) Please refer to the WinPAC user manual.

For Default Firmware:
Step7: Run the I8120W_Utility.exe. Assume the I-8120W is plugged in slot 4 of the
WinPAC, set the slot No. to slot 4.
Step8: Assume the baud of the CAN network is 125 kbps. Set the filter, baud, and
message format as follows:

Setp9: The receiving messages will be shown on the list, and users can use the button
“Send” to send a CAN message. Use “SaveToFile” to save the receptions. In this
case, uncheck the “Show message on the list” to improve the efficiency of the
WinPAC.
Step10: Users can download and run the demos for default firmware on the WinPAC.
You can find them in the CD. The path is shown as follows:

For Updating Firmware:
Step7: Run the I8120W_Utility.exe. Assume the I-8120W is plugged in slot 4 of the
WinPAC, set the slot No. to slot 4. Then, click the button “Update Firmware”.
Step8: Use ftp or USB disk to copy the newer firmware on to the WinPAC.
Step9: The pop-up dialog shows the information of current firmware. Click the button
“Update”. Afterwards, select the newer file from the pop-up dialog.
For User-defined Firmware:
Step7: Users need to build their application of the WinPAC and the firmware of I-8120W
firstly. Use eVC++, WinPAC SDK, I8120.lib and I-8120.h to develop the WinPAC
application. Use TC/BC/TC++/BC++, 186COMM.lib, and 186COMM.h to develop
the firmware of I-8120W. You can find these file in the CD or website. The path is

Step8: When finishing the user-defined firmware of the I-8120W, download it into the
WinPAC. Please refer the Step7 of the “For Updating Firmware”.
Step9: Run your WinPAC application. For more details about how to program the
application and firmware, please refer to the user-defined demos and user manual
for the details.
