Operating instructions

pixel+
This command increments the number of pixels above threshold that are required to
indicate an event. The default is 12.
pixel-
This command decrements the number of pixels above threshold that are required to
indicate an event. The default is 12.
clock
This command prints the current sentuser clock time. The sentuser clock time is based on
the PC’s system time but also uses a time correction value in a file named “TimeOffset”
in the current directory (if it exists). This correction value (which is a text string)
specifies the number of seconds that must be added to the system time to produce the
correct time. A separate application (like the sclock application described below) can be
used to periodically update the TimeOffset file so that accurate time is maintained.
setclock
This command sets the PC’s system time by adding the correction value found in the file
named “TimeOffset” (if it exists).
