Functions and operations
Various mode setup and adjustment of HV-F202SCL are performed by the remote control via CameraLink.
Operation and adjustment way of function utilized are described below.
See "Remote control" (page 10 to 16) and "Command list" (page 17 to 20) about communication method of each command.
(1)
TRIGGER : Setting about external trigger
・MODE : Selection of mode
OFF (Factory setting）
: Trigger mode set to OFF (normal mode).
FIXED SHUTTER : Set to Fixed shutter mode.
ONE TRIGGER : Set to ONE trigger mode.
VD CONTROL : Set to VD reset mode.
・POLARITY : Selection of trigger polarity
POSITIVE (Factory setting) : Input polarity HIGH is made into trigger signal.
NEGATIVE
: Input polarity LOW is made into trigger signal.
・SOURCE : Selection of trigger source
CL-CC1 (Factory setting) : Input trigger signal from CameraLink signal CC1 (see page 4 "Connector").
12pin
: Input trigger signal from 7 pin of 12 pin DCIN/SYNC connector.
* See "Trigger operation and timing chart" (page 25 to 27).
(2)
SHUTTER : Setting of electronic shutter
OFF (Factory setting) : Shutter operation set to OFF (normal shutter).
1/30, 1/60, 1/100,
1/250, 1/1000, 1/2000,
1/10000, 1/50000 second : Set to setting shutter speed (PRESET shutter).
VARIABLE
: Set to shutter speed from 10 second to 1/100000 second (VARIABLE shutter).
-VARIABLE VALUE- : Setting speed of VARIABLE shutter.
10 to 1/100000 second : Electronic shutter can be set in the range of 10 to 1/100,000 second in 1536 steps
(Factory setting is 1/30)
Shutter speed setting value can be derived as follows. (
ShutterSpeed:: μsecond)
a) Setting value xyy obtained from exposure time.
