Windows OS
2.1. Driver Installation
Install EGPC-B4S1 into M.2 B or M key slot of PCIe interface. The two devices named
“CANbus Controller” or “Unknown device” can be found in “Device Manager”.
Run the driver package as administrator.
After installing, please reboot.
After reboot, four CANbus ports can be found in the device manager.
NOTE: Drivers for Windows 64bit need to be signed with digital certificate. The driver is signed with
SHA-2 certificate
Windows 7 must be installed the hotfix KB3033929 to support SHA-2 code signing.

2.2. Loop Back Test Program
We provide a loop back test program with source code in Windows to verify the module.
The test program can be configured by edit “setup.ini”. In majority cases, just keep the
default setting.
Please connect any two ports with each other by using an adapter (MINI GENDER
CHANGER) and connect the other two as well. Then run the “EGPC_B4S1_Sample.exe”
directly.
The test program will detect which ports are connected with each other then run the
test automatically.

When the program is running, for example, CAN1 sends a frame to CAN2, after CAN2
receives the frame CAN2 will check if the frame is correct or not. Then turn to CAN2
sends and CAN1 receives.
If the received CAN port doesn’t receive the frame or the received frame is incorrect, the
program will terminate and show the result is failed.
