Configuration MC132x Users Manual Rev. 0.23

Make sure that a sync signal is present on EXP/CC1 before this command is issued or the “trigger on

CC1” button is pressed on the MC13xx camera configuration tool.

The polarity of the sync signal can be selected with the _Polarity_of_EXP-signal

6.7.6 Frame rate with asynchronous exposure

The frame rate with asynchronous exposure = Frame rate with synchronous exposure – (1 / exposure

time).

6.7.7 Asynchronous exposure, shutter control by pulse width

This operating mode is selected with register 6:

:r6[7..4] = 0xb

Exposure time depends on the width of the external EXP – signal.

6.7.8 Asynchronous exposure, shutter control by timer

This operating mode is selected with register 6:

:r6[7..4] = 0xf

The asynchronous exposure time is dependent on :r2[9..0]. The exposure timer counts as many lines as

are defined in register :r2[9..0].

Exposure time:

= 1/F

sens

* 136 • (1+r2[9..0]) [Sec]

... exposure time

sens

.. sensor clock

example: sensor clock = 66MHz

value of r2[9..0] = 6

= 136 • 6

• 15 ns = 12,2 µs

6.8 Extended command features

For conformity to standards, e.g. GigE Vision the command structure of the camera was extended. It

supports separate commands for direct input of horizontal position, horizontal size and vertical size.

Command: :l<nn><xxxxxxxx> direct programming of additional 32bit registers

<nn> … no. of register,

range 00 … 02 (hex in ascii characters)

<xxxxxxxx> … 32bit value of register, hex in

ascii characters

Response: ACK if enabled by separate command :A<n>

Defined are following registers (command example):

:l00… horizontal start position, hex value as ascii characters,

range (<xxxxxxxx> = ): 00000000 … 0000007e

(same value as for register r4)

1 2 ... 20 21 22 23 24 25 26 27 28 29 30 ... 44 45
