Frame Rate can only be controlled by setting integration time.

To specify programmed frame rate (by using integration time):

1.

Set bit [7] of the Control Register to 0 (Integrate Mode = Internal), and bit [3] of the
Control Register to 0 (Trigger Mode = Internal). To determine the integration time
needed for a specific frame rate use the following equation:

Integration Time = (1/Frame rate) - 32.35ms

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

P

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.

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.
