Windows Software for Updating the Firmware of PEAK-System Hardware Products

The firmware of PEAK-System's hardware products is constantly being improved. A new firmware may contain changes and bug fixes as well as improvements and even new features.

With our free Windows software PEAK-Flash, it is possible to update the firmware of a PC interface connected to the computer or of a hardware product via a CAN connection. For this, the user is guided step by step through the procedure. After the detection of the hardware, the latest firmware version can be uploaded. PEAK-Flash includes the latest firmware of our hardware products and is regularly updated for this.

In addition, PEAK-Flash is used for uploading custom firmware when working with our programmable hardware products such as the PCAN-Router Pro FD.
