Lacerta MGEN Quick Start Manual page 3

You camera has a differnet firmware loaded than the handbox. Please always connect the
camera too, if you upload a new firmware. Reload with camera connected.
- MGEN has a wobble contact at the power socket, and frequently shuts down
The socket has the 5,5/2,1mm dimension. There are cables with similar jacks measuring
5,5/2,5mm out there, please check for the correct dimension. Further, clean the contacts in
jack and socket (using alcohol or proper solvent) as corrosion may cause random power
cutoffs.
- MGEN is suddenly not guiding properly, it looks as if it just omits a direction
Check the ST4 connection to your mount: Go to calibration screen and choose "manual". Now
you can outout ST4 signals by pressing the direction buttons. Set your mount to tracking
mode, and with your ear the the mount head check if the motors change sound when pressing
a button. If all 4 directions are ok, maybe a DEC direction is disabled at DEC parameters. If
not sure, go to misc / modes and choose factory reset.
- MGEN is suddenly not guiding properly, and there is a little cross at the guide star
This happens at emulation mode, for training purposes MGEN can simulate a guidestar. Go to
misc / modes and deactivate emulation mode.
- the guidestar is visible at the display, but MGEN says "star lost"
You have a very big guidestar and use the "NEW" algorithm which is good especially for the
small stars of a finder scope. Switch to "OLD" and it will work also with big stars.
- there are two guidestars in the guide window, and MGEN oscillates between them
You are using algorithm "OLD", in this case please change the sub parameter from "window"
to "partial" and choose one of the two stars. With algorithmus "NEW", this is automated.
- I am still not so familiar with MGEN, and it does not behave as expected
Especially important if you have bought an used MGEN. In course of many years
development many features have been implemented, and maybe something is turned on or off
that you are not aware. Go to misc / modes and use firmware reset which loads the
recommended parameters. They are chosen that way your MGEN should work out of the box
in almost any circumstance.
