Get Cmd: 0 None
Set Cmd: 2
&
Resp: 2
Bytes 0 to 1: ITT filter value
0 = immediate
1-255 = Numerator (Denominator =
256)
0x3F PLATEAU_LEVEL
Specifies the Plateau level for Plateau AGC
Get Cmd: 0 None

Resp: 2
Data Range is 0 to 1000
0x4C AGC_ROI
Gets and sets the region of interest for AGC in normal
and zoom mode. Tau uses 0,0=center and signed
coordinates. When the Get Cmd byte count is 0, the
ROI returned will be the normal ROI if camera is in
normal mode or the zoom ROI if the camera is in
zoom mode. If the Get Cmd byte count is 2, the first 8
bytes contain the normal ROI and second 8 bytes
contain the zoom ROI.
Data range for normal ROI is:
FPA 0604 NTSC
Left: -320,Top: -240, Right:320, Bottom:240
FPA 0604 PAL
Left: -320,Top: -256, Right:320, Bottom:256
Get Cmd: 0 None
