Functions and operations
Various mode setup and adjustment of HV-F203SCL are performed by the remote control via CameraLink.
Operation and adjustment way of function utilized are described below.
See "Remote control" (page 14
~
) and "Command list" (page 21
~
) about communication method of each command.
9.1 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.
-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
CC1 (Factory setting)
: Input trigger signal from CameraLink signal CC1 (see page 5 "Connector").
12pin : Input trigger signal from 7 pin of 12 pin DCIN/SYNC connector.
* See "Trigger operation and timing chart" (page 30
~
).
9.2 SHUTTER : Setting of electronic shutter
OFF : 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 (Factory setting): 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.
