Because this signal is internally OR’ed with the TRIGGER IN Sync input, care must

be taken to ensure the TRIGGER IN signal is equal to a logic 0 while in Serial

Trigger mode.

Controlling Frame Rate

The 1M60 allows you to control frame rate in three ways.



Free Running (Programmed Frame Rate): (default) The camera free runs

with the internally programmed frame rate time and integration time.



External Trigger/Internal Integration: The camera frame rate will be

controlled by the TTL pulse on the TRIGGER IN SMA connector. The camera

will integrate for the programmed integration time. (Reference section 3.10

Controlling Integration Mode)



External Integration: The camera frame rate will be controlled by the TTL

pulse on the TRIGGER IN SMA connector. The camera will integrate fas long

as the pulse is held high. In this mode, TRIGGER IN also controls integration.

(Reference section 3.10 Controlling Integration Mode)

Free Running (Programmed Fame Rate)

To specify programmed frame rate, you must set bit [7] of register 1 = 0 (Integrate

Mode = Internal), and bit [3] of register 1 = 0 (Trigger Mode = Internal). Next, write

the frame rate bit value to the Frame Rate register.

Example: Set the Frame Rate to 30 fps

1.0 Reference section 3.10 Triggering, Integration, and Frame Rate Overview to

ensure the desired frame rate can be supported for the selected binning and

integration modes.

2.0 Using the command 82h, set bit [7] of the data byte to 0 (Integration Mode =

Internal), bit [3] of the data byte to 0 (Trigger Mode = Internal), and bits [2:0]

of shutter control to 000.

NOTE: All bits within the register are written at one time. Ensure the correct

value for all bits are used when changing camera modes.

3.0 Use command 88h to set bits [6:4] of control register 3 to the integration time

value 001.

Value = 30 fps
