Connect your USB to UART interface with the cable. Connect the plug to the GND, Rxd, Txd and 3.3u pins - you may want to solder them in place to make sure that the stay in place.
Now connect the other side with the camera mainboard and solder them in place. Make the connection according to:

Pin #1 Ground → Ground Pin #2 Rxd → Txd Pin #3 Txd → Rxd Pin #4 3.3u → 3.3u

Make sure that the connection is solid and that you don´t have a loose contact somewhere.
The UART Status LED should light up after plugging in the USB connector (depends on the model you are using).

First you have to define a new connection after starting up the HyperTerminal. Type in any name and click on OK.

Select the COM port of your UART interface and confirm with OK. You can check the COM port under Control Panel → Device Manager → Ports COM & LTP. Adjust the settings according to the following screenshot and click OK to confirm.

Save your settings under File → Save As
Now open the connection by double-clicking the shortcut on your desktop that was created in the previous step.
The program should automatically launch the mainboards bootloader - then press ESC. You should now see the following screen.
Now type in the following two commands: del 6 Enter THEN del 7 Enter (Don´t forget the SPACE!!!)

Now type in the following: fx 6 romfs.img 0x7f0e0000 0x7f0e0000 -a Enter Waiting for download... will be displayed.
Select the romfs.img file you downloaded earlier in Transfer → Send file → choose the romfs image file by browsing to the location you extracted it to earlier. Then set the protocol to Xmodem and click on Send.

After the upload is completed repeat these steps for the Linux.zip file. Type in: fx 7 linux.zip 0x7f020000 0x8000 -acxz Enter
Choose the file linux.zip from the earlier download and select the protocol Xmodem.
Now type in boot and confirm with Enter.
You can now reassemble your camera and check if you can connect it to your local cable network.

After starting TeraTerm you first have to set up a new connection. Choose a serial connection (Seriell) and select the port the UART interface is connected to. Confirm these settings with OK. You can check the COM port under Control * Panel → Device Manager → Ports COM & LTP.
Now go to Einstellungen (Settings) and choose Serieller Port (Serial Port).
