7.2 Setting functions
7.2.1
Bit allocation. BA=0, BA=1, BA=2
This command sets the output from 8-bit , 10-bit or 12-bit.
7.2.2
Partial scan. SC=0 through 5.
The CCD scanning format can be selected between full or partial scanning. With partial
scanning only the vertical central part of the CCD sensor is read out with a higher frame rate.
The partial scan is done by a fast dump read out of the lines in the vertical CCD register down
to the top of the partial image. This central part of the image is read out with normal speed.
The lines below the partial image are read out and dumped with a high speed.
Note: The color sequence for CB-140 MCL differs in partial scan modes. Refer to chapter 6.3.
7.2.3
Vertical binning VB=0, VB=1
This function is only for CM-140MCL camera.
The CM-140MCL has only vertical binning mode. With V binning the pixel charge from 2
adjacent lines are added together in the horizontal CCD register. It is done by double pulses
to the vertical CCD register. V Binning cannot be used together with partial scanning.
7.2.4
Shutter mode. SM=0 and SM=1
With SM=0 this function selects the shutter from the 9 fixed steps (SH=0 through SH=9SH).
With SM=1 from programmable in 1051 steps (PE=2 through PE=1052). In association with
programmable exposure, fine exposure function is available.
7.2.5
Trigger input select. TI=0, TI=1.
This function selects the trigger input to be through Camera Link (TI=0), or as TTL through the
12 pin Hirose connector (TI=1).
7.2.6
Trigger polarity. TP=0, TP=1.
The active trigger polarity is normally low (TP=0). It can be inverted it to active high (TP=1).
7.2.7
Gain level. GA=-84 through +670
GA=0 is 0dB gain, which is the normal working point. The range is from -3 dB to +24 dB.
7.2.8
Black level. BL=255 through BL=767.
Black level (or set-up level) will set the video level for black. Factory setting is 128LSB for
12-bit ,32 LSB for 10-bit or 8 LSB for 8-bit.
7.3 Save and Load Functions.
The following commands are for storing and loading camera settings in the camera EEPROM.
