4.3.7 Shutter

Shutter mode is saved in address 7 in the RAM bank.

In Normal shutter mode (DS=0), Manual and Async can be selected. The shutter speed can be changed

by setting the proper value on the Shutter Dial (0 through 9). If a value is set on the Shutter Dial, then

the preset values for this dial are loaded from different locations of the address in RAM.

Address 7

MSB LSB

X G DSASD3D2D1D0

G Gamma Conversion Mode

(0: off (1.0), 1: on (0.45))

DS Direct Shutter Flag

(0: Normal Shutter, 1: Direct Shutter)

AS Async Shutter Flag

(0: Manual, 1: Async)

D3:0 Shutter Dial

(0 to 9)

In Direct Shutter mode (DS=1), Manual and Async mode can be selected. In Direct Shutter mode, the

Shutter Dial has no effect; the preset shutter speed value is loaded from address A, B (hex) or 3E, 3F

(Hex) (Async). Users can upload the Direct Shutter preset value by accessing these direct shutter preset

addresses.

In order to convert the exposing line count (H) to direct shutter speed, the following formula is applied:

Direct Shutter Manual:

Shutter Speed = 1049 (dec) - n ------>TMC-1000

524 (dec) - n ------>TMC-6700

Direct Shutter Async:

Shutter Speed = 8-n when n=1H~8H
