Page 21: Firmware Upload
PCAN-Router – User Manual Firmware Upload The microcontroller in the PCAN-Router can be equipped with new firmware in two different ways: Via CAN (recommended): Via a CAN channel and the Windows software PEAK-Flash, the firmware can be transferred from the computer to the PCAN- Router. -
Page 22: Preparing Hardware
Preparing Hardware For an upload of new firmware via CAN, the CAN bootloader must be activated in the PCAN-Router. This can only be done via CAN channel 1. Firmware transfer, on the other hand, can also be done via CAN channel 2. -
Page 23: Firmware Transfer
CAN2 orange Firmware Transfer On the PCAN-Router a new version of the firmware can be transferred via both CAN channels. Only the bootloader can be activated via the first CAN channel. The firmware is uploaded via a CAN bus using the supplied Windows program PEAK-Flash. - Page 24 PCAN-Router – User Manual Figure 7: Main window of PEAK-Flash Click the Next button.

Page 27: Uploading Firmware Via The Serial Connections
Attention! Electrostatic discharge (ESD) can damage or destroy components on the card. Take precautions to avoid ESD. Switch the PCAN-Router off by disconnecting it from the power supply. Open the casing of the PCAN-Router by removing the screws in order to gain access to the board. - Page 28 PCAN-Router – User Manual Switch on the PCAN-Router by applying a supply voltage. Due to the Low level on port P0.14 of the microcontroller, the PCAN-Router starts the bootloader for serial copying. The two LEDs remain off.
