(6) Verify version string by reading serial no. and firmware versions (command: :v). The new

firmware version will be displayed as part of the version string. If the version is identical to

the expected the camera is ready to use for capturing images.

6.11 Horizontal pixelbinning

Pixelbinning adds the gray values of two adjacent pixels and outputs it as one pixel with double sensi-

tivity. In X-direction only 512 pixels are needed to cover the sensors full size.

To retain aspect ratio, every second line is discarded, if this feature is not disabled by setting Bit 8 of

Command: :r7010

This is an example for enabling this function. Depending on the wanted camera

mode it can be necessary to add additional bits of this register .

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

If discarding of every other line is not disabled (:r61xx), the contents of :r1 is doubled in camera logic.

To address a specific line on the sensor, the value written into :r1 has to be divided by two and :r3 must

not exceed 1ffh.

Example:

To output 256 lines from line 128, set r1 = 63 and r3 = 255 (=0xff).

6.12 Vertical pixelbinning

Vertical pixelbinning adds the gray values of two superimposed pixel of a column. This doubles sensi-

tivity and vertical field of view. To retain aspect ratio, in addition horizontal binning must be activated.

To activate, set bit 2 in register 6.

Command: :r6034

This is an example for enabling this function. Depending on the wanted camera

mode it can be necessary to add additional bits of this register .

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

6.13 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

This is an example for enabling this function. Depending on the wanted camera

mode it can be necessary to add additional bits of this register.

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