Aim Brightness
Parameter # 668 (SSI # F1h 9Ch)
This feature sets the brightness of the aim pattern. The default is 0, which indicates that the aim pattern is
always on in between camera exposures. For values above 0, each increment of the brightness value
increments the aim duration 0.5 ms.
To program Aim Brightness, scan this bar code followed by three numeric bar codes in Appendix D, Numeric
Bar Codes that correspond to the value representing brightness. Settings range from 0 to 255. The maximum
aim duration is limited by the frame time, so the recommended range is 0 to 30 when the frame rate is set to 60
fps.
Illumination Brightness
Parameter # 669 (SSI # F1h 9Dh)
This feature sets the brightness of the illumination by altering LED power. The default is 10, which is maximum
LED brightness. For values from 1 to 10, LED brightness varies from lowest to highest level of brightness.
To program Illumination Brightness, scan this bar code followed by two numeric bar codes in Appendix D,
Numeric Bar Codes that correspond to the value of desired illumination brightness. For example, to set
Illumination Brightness to 6, scan the bar code below followed by the 0 and 6 bar codes.
