SETUP
This mode allows the user to enter specific values for the operation of the controller. The
following parameters are stored in battery backed-up memory, allowing these values to
be re-Ioaded the next time the controller is powered up.
TIME, MONTH, DAY, YEAR Current Time, Month, Day, Year
This information is required for the correct operation of the system. It is used for setting
the telescope limits as well a calculating the Planet positions.
UT-OFF Universal Time Offset from GMT
The Universal time offset is used to calculate the local sidereal time. The local sidereal
time is used for performing the meridian flip of the mount.
LAT Your Site Latitude (.:!:.DD.dd_degrees,tenths of deg)
LONG Your Site Longitude (!:DDD.d degrees, tenths of deg)
These values are used for checking the horizon limits and calculating local sidereal time
DISBRI LED Display Brightness (0 - 9)
RETBRI Illumined Reticle Brightness (0 - 9)
FOCSPD Focus Motor Speed (0 - 9)
SCRSPD Display Scroll Speed (0 - 9)
These values are user configurable for setting preferences.
SLWSPD Slew Speed (30 - 70)
This value sets the motor maximum slew speed. A slower speed might be required for a
mount that is heavily loaded or un-balanced.
TSCOPE Telescope Type (0 - 3)
This entry selects the current mount that is being used. This is used for calculating the
PEC and tracking rates.
o = Losmandy G-11
1 = Losmandy GM-8 Mount
2 = Celestron CI700 mount
3 = Reserved for future use
DECBAK DEC Backlash Reduction (0 - 99)
RABAK RA Backlash Reduction (0 - 99)
These two values are available to the user for Telescope types 2 and above. These
values can be adjusted the remove the gear-train backlash that exists. Adjustment is
performed while looking through an eyepiece while alternately pressinq the SET button
along with a direction button (N,S,E,W) and adjusting the backlash value until the motor
delay is removed.
NOTE: Pressing any motion button (SLEW, SET, NORTH, SOUTH, EAST, WEST) will escape
from ANY mode.
The table on the following pages shows the system control flow in tabular form. The contents of
