7.15 Commands GAR2 , GAG2, GAB2 and GAIR2 – Fine Gain (R,G, B and NIR)
Fine gain can be digitally controlled.
Settings:
6554 to9830
x0.8 (6554/8192) to x1.2(9830/8192) (R,G,B and NIR)
7.16 Command GM - Gain Mode
Selects gain mode.
Settings:
0=Master Tracking (Factory default)
1=Individual
7.17 Command LR - Line Rate (Scan Rate)
This function is used only when there is not an external trigger pulse (e.g. from an
encoder) available. It allows the user to program the line rate, in order to match the speed
of the object being scanned. In the No-Shutter mode, the exposure time is directly
proportional to the line rate (T
exp
= 1/line rate)
Settings:
No-Shutter Mode
2100 to 2150400, in 25ns increments (19 kHz to 18 Hz)
No-Shutter Mode
2150 to 2150400, in 25ns increments (18.6 kHz to 18 Hz)
Associated functions:
Trigger origin, TG=0
Applicable modes:
No-Shutter with internal trigger (TR=0)
Shutter-Select with internal trigger (TR=1)
Note
•
The data can be stored in the camera memory for next start up.
•
It is recommended to use 52.5
μ
s to 2ms of line rate because the black level is stable
in this range.
7.18 Command LUTC - LUT Control
The SW-2001Q-CL has an internal LUT(Look Up Table) for setting gamma. Command LUTC
selects gamma OFF, Gamma 0.45 or LUT.
Settings:
0 = Off
1 = 0.45
2 = User
γ
=0.45
In this mode, R,G,B and NIR have the same characteristics for gamma.
