If we choose this, we can see on the display or when the Power led flashes that the
device is in upgrade mode, then Disconnect!
You can then start the upload via the firmware updater. It may happen that some
anti-virus programs prevent the Updater from working. In such a case, temporarily
disable our anti-virus application.
To start uploading, press the
Upload firmware button. An uploading message at the
bottom of the window shows the process status. When the uploading is in progress,
the LED light of the serial communication is flashing. Red flashing is the sign of back
reading.
When the process is complete, the device is restarting and the display shows the
new version number.
Troubleshooting:
If you encounter problems with your FMC , please refer first to the following advices,
before you contact your dealer. It may help to regain full functionality.
- the focuser moves out when pressing IN:
Reverse motor direction in motor menu
- the motor is moving, but the focuser is not:
Check if the coupler is connected properly to the focuser worm
- the motor is not moving:
is it at min or max position? Change the cable (Ethernet cable, not crossed),
See if the PIN contacts in the jacks are ok and clean
- the motor sounds irregular sometimes:
especially when not connected to the focuser worm, there are resonances
- the worm is connected, but at some rotation position it feels tighter:
make the motor fixation slightly loose and turn the worm manually, to allow
the motor to settle in respect to the focuser worm

restart in in update mode and do a factory reset
- when power on,
FMC
always starts with Position 0 (zero):
set StartSavedPos to Yes.
