The gray levels along the center line of the image are saved in volatile memory and then subtracted
form all lines of the following images, as long as this bit remains set.
6.12 Digital gain
Out of the 10-bits sensor data either the most significant 8 bits (gain 1), or bits 8..1 (gain 2), or the least
significant 8 bits (gain 4) are selected.
Command:
:r700x
x = 0: gain 1
x = 4: gain 2
x = 8: gain 4
6.13 External clock input
MC132x frequency synthesizer can use the Camera Link® used to synchronize several MC132x to one
master clock.
To activate set Bit 9 of register 7.
Command example:
:r7200
response: none
*
If the external reference clock is different from
3.6864 MHz, the codes for the clock synthesizer have
to be recalculated.
6.14 Polarity of EXP-signal
The polarity of the EXP-signal can be positive- or negative active.
Use :r7[8] to select.
Negativ = :r7[8] = 1
Positiv = :r7[8] = 0
Command example:
:r7100
Response: none
6.15 Test image
For testing of camera logic and video data transmission, sensor data can be replaced by an internal gray
scale pattern with pixel values of 0..127. Use digital gain command to see pixel values of 0..255.
Command example:
:r7040
r7[6]
Response: none
6.16 Image counter
If a sequence of frames is to be recorded for long time at a high frame rate, it can be useful to mark the
images for later identification or check for completeness.
