Now the upgrade is finished.
Typical Errors:
1. Invalid Port Number: in Device Manager, make sure you have the correct COM port
number for CP210x.
2. Wrong “.bin” file: make sure you have the correct “.bin” file for firmware upgrade.
3. Wrong downloader, you should use iOptron Downloader instead of the Flash
Downloader.
4. Use CP210x driver provided by iOptron. The newest version from SiLab may not work
properly for iOptron’s hand controller.
What can I do if the firmware is not loading or the screen is blank, due to any reason?
y Turn on the mount to power on the hand controller (the key pad should be lit)
y Click on the iOptron Downloader. Change the Serial Port to the right COM port in the
pull-down menu (example: COM4)
y Click on Open Data ile(O) button to select the right Firmware for your hand controller.
(example: 8401_Ver090701.bin)
y DON’T click on Start Download (D) button yet. Turn the mount power off.
y Turn the mount power back on. Right after hearing the “beep”, click on Start
Download (D) button. The timing is very important. The downloading process will begin
y When the download is successfully finished, turn the mount off and back on to check
the hand controller. Double check the settings, such as time and site info, mount type,
anti-backlash, to see if they are changed
y You may need to practice a few times to get the procedure work correctly.
