APPENDIX B: Updating Using an SD Card Besides using the Web interface, it is also possible to update the firmware of the Z3-DM368-RPS using an SD card. The process requires a Windows PC, an SD card, and the ZWriter tool (included with the RPS). The process for updating via SD card is as follows: (1) Locate the img update file received from Z3 and copy it to your Windows computer. -
