Operating Basics
Refer to the section describing the “Initial Operation and Testing” for initial
preparation to put your VCM-D1 into operation.
Function Switches
Located at the Rear Panel and labeled “Function” are eight miniature slide switches.
Switches A – F allow the user to select the active state of the four BNC inputs and two BNC
outputs. When the switch actuators are selected to the down position (a small hole will be visible
just above the switch’s actuator, this actuator could be either black or red), the corresponding
BNC input or output will be TTL active low. This indicates that a logic “0” (0 volts) will activate
the selected input or what the output will switch to when active.
The switches must be in this
(the active low) position to activate the inputs from a remote activate cable such as the 710R
(handheld) or the 710R/F (foot activated).
DO NOT CONNECT A 710R OR 710R/F TO AN OUTPUT. THE OUTPUT COULD
BECOME DAMAGED.
By sliding any of these switch actuators to the up position (covering the small hole), the
selected BNC input will become TTL active high. This indicates that a logic “1” (+5 volts) will
activate the selected input or produce an active high output.
Switch
G will allow the user to disable the electronic sync circuit. Slide switch to the up
position to disable the electronic sync. This shuts off the infrared emitter internal to the shutter
which intern disables the SYNC OUTPUT.
Switch H selects HIGH/LOW pulse energy. HIGH energy is required to operate the
VS35 (35mm aperture) and larger aperture shutters. When the switch is in the down (Lower)
position (a small hole will be visible just above the switch’s actuator, this actuator could be either
black or red), the pulse energy is selected LOW. When the switch actuator is in the up (Upper)
position (covering the small hole), the pulse energy is selected HIGH.
THE HIGH ENERGY SETTING MUST BE USED FOR ONLY THE VS35 AND
LARGER APERTURE SHUTTERS. USE THE LOW POSITION FOR ALL OTHER
UNIBLITZ
SHUTTERS. USE OF THE HIGH POSITION FOR SHUTTER APERTURES
SMALLER THAN THE VS35 AND LARGER APERTURE DEVICES COULD CAUSE
IRREPARABLE DAMAGE TO THE SHUTTER USED AND WILL VOID THE SHUTTER’S
LIMITED WARRANTY.
GATE INPUT
The GATE INPUT is used in conjunction with the TRIGGER INPUT. This input allows the user
to “pick” one or a finite number of trigger pulses to trigger the controller from a continuous
stream of pulses presented at the TRIGGER INPUT.
See Figure #5. The following description
assumes the GATE INPUT is selected active high (function switch ”D” up position) and the
TRIGGER INPUT is selected to the active low state (function switch “A” down position).
When a
stream of trigger pulses is input to the TRIGGER INPUT and the GATE INPUT is in the high
state (TTL logic “1”, +5V), the trigger signals will operate the
VCM-D1 as described in the
