Main Display
The front panel contains six keypads that can be used for various functions and navigating through
the display.
The Main display screen contains four display windows, each is located in a quadrant of the display.
The windows are
MODE
,
TRIGGER
,
TIME OPEN
, and
TIME CLOSED
. The keypads will modify
(edit) the active quadrant which is indicated by a “
_
” next to the quadrant. The
SELECT
key is used
to move between quadrants.
MODE
When the active window indicator is in the
MODE
quadrant (upper right) the
▲
▼
keys will sequence
through the modes
SINGLE, AUTO
,
MANUAL
,
X GATE
, and
REP
.
SINGLE
– In the single event mode the shutter will open and close at the occurrence of each
trigger using the parameters displayed in the (open/close) time windows.
AUTO
– In the automatic mode the shutter will continually open and close after a single event
using the parameters displayed in the (open/close) time windows.
MANUAL
- In manual mode, the displays in the other quadrants will blank and the
ENABLE
key
will toggle the operation of the shutter.
X GATE
- In the external gate mode the other displays will blank and the control of the shutter
will follow the signal on the input trigger BNC connector on the rear panel. The shutter will be
open when the signal is active high (TTL). The shutter will be closed when active low (TTL).
REP
– In the repeat mode the open/close time sequence will be executed the number of times
shown next to the REP display. The unit may be programmed to repeat the cycle anywhere
between 1 and 99 times. While the active display is in the REP mode the number of events may
be modified by using the
◄
key to place the curser under the number displayed and using the
▲▼
keys to increment or decrement the number. The repeat sequence begins with activation of
a trigger.
TRIGGER
When the active window indicator is in
TRIGGER
quadrant (lower right) the
▲
▼
keys will sequence
through the trigger options
INT
,
EXT
.
INT
- In the internal mode pressing the
ENABLE
key activates or enables the operation of the
shutter as per the selected mode and timing parameters. While the shutter controller is executing
a sequence (actively running) the “ENABLED” indicator will illuminate on the front panel. In all
modes of operation pressing
ENABLE
key while the unit is “enabled” will disable the shutter.
EXT
– In the external trigger mode a rising edge on INPUT TRIGGER BNC input will start
execution of the parameters programmed on the unit. The unit will respond to the external trigger
after the
ENABLE
key is pressed. When enabled the “ENABLED” indicator will illuminate on the
front panel. In all modes of operation pressing
ENABLE
key while the unit is “enabled” will
disable the shutter.
TIME OPEN (ON)
When the active window indicator is in
TIME OPEN
quadrant (upper left) the
▲
▼
keys will increment
and decrement the indicated digit. The
◄►
keys will move between digits. This indicates how long the
shutter will be open (when the shutter is not connected it indicates the “high” time of the TTL output
trigger).
