7.12 Command EI – Interlocked R, G, B & NIR Exposure
When this function enabled (interlocked), exposure time for all four channels is selected
by setting the green channel and the red, blue and NIR channels will track.
To obtain white balance, adjust red and blue channels, PER and PEB. It is thereafter
possible to adjust overall exposure time by using the command PEG. The red and blue
channels will track the green channel proportionally, thus maintaining white balance
settings.

Note: The LQ-050CL has a priority for the line rate setting. If the exposure is use around
the longest exposure speed which is nearly equal to the trigger cycle, please note the
followings.
1. Shutter select mode in the internal trigger
The maximum shutter speed is the setting line rate minus 52clk(1.3μs).
2. Shutter select mode in the external trigger
The maximum shutter speed is the provided trigger cycle minus 60 clocks (1.5μs) .
7.13 Command GA – Master Gain Level
This function is a global gain adjustment for all channels. There are two ways to adjust
gain, one is "Master Tracking" and the other is "Individual". Command GM selects
a required mode. The gain setting is done in the analog domain where 1LSB
equals 0.03dB.
Master Mode:
Individual Mode:
Associated functions:
Note: The adjustment range is available under 7800K light. If light with a color
temperature other than 7800K is used, the adjustable range might be limited.
7.14 Commands GAR, GAB and GAIR – Gain Level Red, Blue and NIR.
In conjunction with the Command GA, this function allows the individual setting of gain for
all channels, or it can be used for fine adjustment after one push white balance is executed.
It is important to note that increasing the gain will lead to an increased noise level and
reduced S/N-Ratio. 1LSB equals 0.03dB.

 The adjustment range is available under 7800K light. If light with a color
