
Gain
:
( Gain with GainSelector = GainAll )
Set the Amplification Gain. This command is available in the CommCam “Gain & Offset” section :
 Read function : “r gain”;
Returned by the camera : Value from 0 to 6193 corresponding to a Gain range of 0dB to +8dB calculated as following
: Gain(dB) = 20.log(1+ Gain/4096).

Write function : “w gain” <int> ;

Tap Gain ( Gain with GainSelector = Tap X) :
 Read function : “r fga<tap>”; <tap> is 1 to 4
Returns the Gain value for the tap. Ex : “
r fga1
” returns Gain value Tap1.

Write function : “w fga<tap> <value>”
 <tap> : 1 to 4
 <value> : from -128 to +127 by step of 1 (0,0021dB each step)

Digital Gain (
Gain
with
GainSelector
=
DigitalAll
) : Set the global Digital Gain. This command is available in the CommCam
“Gain & Offset” section :

Read function : “r gdig”;
Returned by the camera : Integer value from 0 to 255. The corresponding Gain is calculated as 20log(1+val/64) in
dB
 Write function : “w gdig” <int> ;

Digital Offset (
BlackLevelRaw
with
BlackLevelSelector
=
All
) : Set the global Digital Offset. This command is available in
the CommCam “Gain & Offset” section :

Read function : “r offs”;
Returned by the camera : Value from –4096 to +4095 in LSB
 Write function : “w offs” <int> ;
The Contrast Expansion (both Digital Gain & Offset) will be automatically disabled if the LUT is enabled..

Tap Balance Gains Enable Switch (
TapBalanceGainEnable
) :

Read function : “r tbe”;
Returns the Gain value for the tap. Ex : “
r fga1
” returns Gain value Tap1.
 Write function : “w tbe <val>” with <val> : 0 or 1

0 : Disables the Tap Balance Gains
 1 : Enables the Tap Balance Gains

ROI Gain () : Set the Gain for the ROI Gain feature.
 Read function : “r roig”;
Returned by the camera : Value from 0 to 2047 (U1.9) corresponding to a Gain range from x1 to x1,999 and
calculated as following : (1+ Gain/1024).
 Write function : “w roig” <value> ;

ROI Set () : Set the ROI and apply the Gain for ROI Gain Feature.
 Read function : “r rois”;
Returns the ROI set for the last ROI gain command
 Write function : “w rois <val>” with <val> : Hexadecimal combination of Start and Stop address for the ROI
(both on 16bits) :
0xStartAdr0xStopAdr

Start address : from 0 to 16382 (0x000 to 0x3FFE)
 Stop address : from 1 to 16383 (0x001 to 0x3FFF)
