2.
Write the 3-byte Integration value (in µs) to the three Integration registers. These three bytes
are then combined to form a 24 bit frame Integration time. The number programmed in the
three registers should not be below 10
µ
S (0000Ah), or above the calculated value noted in
section
3.13 Triggering, Integration, and Frame Rate Overview.
3.
Using the command 82h, set bit [7] of the data byte to 0 (Integration Mode = Internal) and bit
[3] of the data byte to 0 (Trigger Mode = Internal).
NOTE:
All bits within the register are written at one time. Ensure the correct value for all bits
are used when changing camera modes.
4. Use commands 8Ah, 8Bh, 8Ch to set the 24-bit Integration time value.

External Trigger/Programmed Integration
This is the same as Programmed Integration/SMA Trigger Mode or Programmed Integration/Serial
Trigger Mode. Reference to section 3.14 Controlling Integration Mode.
Example: Set the Frame Rate to 2.5 fps
1.
Refer to section 3.13 Triggering, Integration, and Frame Rate Overview to ensure that the
desired frame rate can be supported for the selected binning and integration modes.
2.
Using the command 81h, set bit [0] of the data byte to 0 (Integration Mode = Internal) and bit
[3] of the data byte to 1 (Trigger Mode = External).
NOTE:
All bits within the register are written at one time. Ensure the correct value for all bits
are used when changing camera modes.
3. Set the desired integration time per section 3.14 – Controlling Integration.
4.
Each TTL rising edge on the SMA connector or serial bit [0] of the Control Register will
initiate a new frame of data, using the programmed integration time. To achieve 2.5 fps, a
TTL pulse must be sent to the camera every 400 ms (1/2.5).
External Integration
This is the same as the External Integration/SMA Trigger Mode or the External Integration/Serial
Trigger Mode. Refer to section 3.14 Controlling Integration Mode.
