Set the exposure time of the electronic shutter. Auto exposure (CCD IRIS) can be also set.

(1)Manual adjustment

Command = 82000nnnh

<When DFW-SX900>nnn: Adjust in the range of 7F1h (long) – C2Dh (short).

B22h (1/30 sec) is the standard value.

2.0sec ≥ Shutter Speed ≥ 1/7.5 sec

nnn = 800h – 7.5 ∗ Shutter Speed (sec) 1/7.5 sec > Shutter Speed ≥ 1/5,882 sec

nnn = 3116.4 – 7999 ∗ Shutter Speed (sec) Shutter Speed = 1/10,000 sec

nnn = C2Ch

Shutter Speed = 1/20,000 sec nnn = C2Dh

<When DFW-X700>nnn: Adjust in the range of 7E2h (long) – B20h (short). 992h (1/30 sec) is the standard value.

2.0sec ≥ Shutter Speed ≥ 1/15 sec

nnn = 800h – 15 ∗ Shutter Speed (sec) 1/15 sec > Shutter Speed ≥ 1/8,361 sec

nnn = 2848.4 – 11962 ∗ Shutter Speed (sec) Shutter Speed = 1/20,000 sec

nnn = B20h

NOTE : When nnn < 800h, do not turn ON the Gain and White Balance Auto functions.

(2) Auto exposure (CCD IRIS)
ON : Command = 83000∗∗∗h	∗∗∗: Undefined

OFF : Specify 82000mmmh. (Or read out the shutter speed once and rewrite the value.)

NOTE : When the CSR F0F00830h Trigger is ON, do not set Auto exposure to ON.

(3)Shutter OFF

Command = 80000000h

At this time, the shutter speed will be 1/30 seconds.
