Configuration MC132x Users Manual Rev. 0.22

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 s

nthesizer 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.
