The line executed in the timer file is the line where                 
the current time is within the listed interval. 
 
The operator writing a new timer file must follow this format 

exactly

. The format of the sequence file name can be different, 

i.e. it can be at another hard-disk and in another directory.  
 
The current version of the ACC2 program can accept 
maximum 100 lines from the timer file. 
 
Note: In order for the ACC2 program to read the correct date 
and time format the Windows 95 date and time format must be set 
correctly. The date and time is every second printed in the         
right upper corner of the ACC2 window. This format has to be 
(If this ever has to be changed, it is changed by using the 
Regional Settings in the Windows 95 Control Panel): 
 
    y

yyy-mm-dd hh:mm:ss

 

 
    Example:  
 
    

1997-11-

15

 10:17:24

 

 
 
CORRECT DATE AND TIME: 
If the Garmin GPS 12XL receiver is not used, the date and time 
of the computer should be set to correct UT time. This is done 
in the Windows 95 control panel, Date/Time . 
 
      

3) The sequence file: 
--------------------- 

 
The current sequence file is the filename at the end of the 
line executed in the current timer file. The sequence file 
determines the type of sequence executed. The '$' below are  
numerical characters ('0', '1', ..  '9'). 
 
Lines starting with # in first column are comment lines. The 
other lines in the sequence file, must be executable lines. 
 
When the ACC2 program execute a sequence the sequence length is 
60 seconds. 
 
The executable lines have the  format: 
 

t$$ f$ e$$$ g$ s$ u$ c$ 

     

or 

 

b$$ f$ e$$$ g$ s$ u$ c$

 

 

t$$ 

is the second in the minute when program is running in 

normal mode. 

b$$ 

is the second in the minute when program is
