15% due to fluctuations in the CMOS manufacturing process.

The user can display two panels: Command Terminal and a
download utility.

Command Terminal
– shows information about all the
commands sent to or received from the camera. User can type in
CHEETAH command directly in the text box provided – Figure
5.5. All commands must start with
0x
followed by
ADDRESS
and
DATA
, without spaces – refer to chapter 4 for more
information. The “Disable Polling” check box will turn on/off
the polling commands (such as Frame Time, Exposure time,
Frame Rate and Sensor Temperature) in the dialog windows. The
user can change the polling time by entering the desired number
in the window. If for some reason the camera returns an error,
when command was sent to the camera, the GUI will respond
with a pop-up window displaying an error message. The user has
option to disable the error checking by enabling the “Disable
Error Checking” box.
