Gemini Users Manual 72
These functions allow you to use the Gemini as an alarm timer and to control the safety
limit buzzer. The time for sounding the alarm (useful for determining when to close a
camera's shutter) is set in UTC using “Alarm/Buzzer→Set Alarm Time.” Although the
alarm time remains stored in Gemini's real time clock (RTC), it is always set to "off"
after powering up. You can activate the alarm by executing "Alarm/Buzzer →Activate
Alarm" and can disable the alarm by executing "Alarm/Buzzer →Set Alarm Off."
Selecting "Alarm/Buzzer →Turn Buzzer Off" or "Alarm/Buzzer →Turn Buzzer On"
allows the user to disable or enable the buzzer sound while keeping the alarm in an
activated condition. These commands also control whether or not the buzzer sounds
when Gemini has reached one of the RA safety limits. Note that turning the buzzer off
only affects the buzzer; it does not disable the actual safety limit.
5.3.10.5 UTC Date/Time
The "UTC Date/Time" menu item is where you set Gemini's real time clock (RTC).
Upon executing "UTC Date/Time" the UTC date and time display freezes but the RTC
continues to keep time.
The display of date and time from left to right reads as follows: "yymm.dd hh:mm:ss"
(yy = year, mm = month, dd = day, hh = hour, mm = minutes, ss = seconds). You can
modify the displayed time and date in the usual way by using the Hand Controller's DEC
buttons to change the current digit, and using the RA buttons to move from digit to digit.
When you are at the far right digit of the display, pressing the RA+ button causes the new
UTC date and time, to the second, to be entered into the RTC.
Make sure that you properly consider the time zone difference while calculating the UTC
time. Western longitudes (e.g. the Americas) are behind, eastern longitudes (e.g. Asia,
Australia) ahead of UTC. This may also affect the date. You can use a GPS receiver to
set the correct values. You can also visit http://www:DocGoerlich.de/utcdate.php to get
the current UTC date and time in Gemini format.
IMPORTANT: If you use the “Setup→UTC Date/Time” menu item to change the date
and/or time of Gemini's RTC immediately after a Cold Start, the new values are not used
to set the initial pointing model until Gemini is powered off, powered back on, and Cold
Started again. This does not apply if you set the date and time when prompted during the
Cold Start, a feature first made available with Level 3 version 1.01. Refer to section
2.4.2.1 Cold Start Setup Options for an explanation of how this is done.
5.3.10.6 Credit Info
This menu item loads the information buffer and displays credits for those who
participated significantly in Gemini's design and development.
