C20 Focus Motor
---------------

October 14, 2006


The focuser on the C20 is a unique and known to be in use on only two
commercially delivered C20's as of October 2006. However, this note
clarifies the use of the auxiliary command set.


From Andre Paquette --

The key bit of information is that the focuser behaves almost
exactly like one of the motor control devices outlined in chapter 4, so
most of the basic commands in that section work with the focuser. The
big difference is that the focuser is on device 18 (0x12) instead of
devices 16 and 17.

For example, an aux command to move the focuser forward at rate 5 would
look like:
0x3b 0x04 0x0d 0x12 0x24 0x05

If you wanted to send the same command via the hand control interface it
would look like:
'P', 0x02, 0x12, 0x24, 0x05, 0x00, 0x00, 0x00
