FUNCTIONS OF INDIVIDUAL KEYS: PRESS and RELEASE
Note that when the key is pressed the command is sent to CPU at the point of release,
not when the contact is made.
(PGM) PROGRAM - Allows the user to enter in a set of data specifications from scratch.
Data specifications include preset shot, preset total, exposure time, lapse time, load count, and total count.
The PROGRAM key is used in a toggle manner, once for entering the program mode, and second time for
NOTE: The (PGM) key when used after data has already been loaded, will reset the count, lapse time,
preset total, and preset shot count to zero. Useful when starting a new scene.
(MOD) MODIFY- Displays the previously programmed set of specs, and allows the user to modify them if desired. MODIFY is also a toggle key, similar to PROGRAM. NOTE; When in the MODIFY mode and the PAUSE key is pressed the LED display will turn off to save power under battery operation.
(VER) VERIFY - Merely displays the pre-programmed specs. VERIFY is not a
toggle key, and should be used with
each item to be checked. The verified number will be displayed for 2 sec.
COUNTER OPERATION KEYS:
(LOAD COUNT) LOAD COUNT - Pre loads the display counter with a particular value for each scene, such as operating the control off of a cue sheet. This number is reset by the program key, unlike the total count which is not.
(TOTAL COUNT) TOTAL COUNT - This key when pressed alone will display for 2
sec. the total net frame
count runoff in a single shooting day. This value may also be pre-loaded if desired.
EXPOSURE SPECIFICATION KEYS:
(PRESET TOTAL) PRESET TOTAL - Presets the desired number of frames tube exposed, either when using RUN,
or when activating the external trigger input.
(EXP TIME) EXPOSURE TIME - Selects the desired exposure time in increments of 0.1 seconds. The minimum open-shutter exposure time of 0.175 seconds is automatically accounted for. "0" exposure time = this value.
(LAPSE TIME) LAPSE TIME - Selects the desired lapse time in increments of 0.1
seconds. The minimum revolving motor lapse time of 0.5 seconds is automatically
accounted for, as well as any specified exposure time. "0" lapse
time =this minimum value.
(PRESET SHOT) PRESET SHOT - Presets the number of exposures desired per time
lapse interval. This would be
useful for special stop motion studies. Normally only1 shot is preset per time lapse interval. This number is
always equal to 1 unless changed. If zero is entered it will automatically be set back to one.
MOTOR OPERATION KEYS:
(FWD) FORWARD - Directs the motor to run the camera transport in the forward direction. This is the only motor mode which will use the time exposure and time lapse options.
(REV) REVERSE - Reverses the direction of the camera motor. Time exposure and time lapse sequences are ignored.
(SHTR OPEN) SHUTTER OPEN - Runs the motor to the shutter open position and
leaves it there. Subsequent uses
of the individual frame or preset count function will advance the film with shutter open, as would be useful for rotoscoping. Time exposure and time lapse sequences are ignored.
HTR CLOSED) SHUTTER CLOSED - Closes the camera shutter, and returns control back into the normal mode of operation. Time exposure and time lapse sequences are restored for forward advancing operation.
(RUN) RUN - Executes the currently programmed sequence. NOTE: If the preset total equals zero the run key will execute zero exposes. (PAUSE) PAUSE - Pauses the currently running sequence. The sequence continues only
when PAUSE is pressed a second time. When in the PAUSE mode, the verify key may be used to display any
of the display oriented keys, and the stop key may be pressed to abort the currently running sequences.
(STOP) STOP - Entirely aborts the currently running sequence.
(INDIV) INDIVIDUAL - Runs a single exposure in whatever mode of operation which was specified.
(CAPON) CAPPING SHUTTER ON - Enables the external trigger output option for
devices, such as capping shutter assemblies, or photo flood accessories, etc. The trigger signal spans
beyond the duration of the exposure interval.
(CAP OFF) CAPPING SHUTTER OFF - Disables the external trigger output option.
(1) to (9) NUMBER KEYS - are used to enter data specification in conventional calculator style.
(.) DECIMAL POINT - should be used only with exposure time or lapse time specs.
(CLR) CLEAR - Clears the currently entered data, in the event of a correction, or modification.
(ENTER) ENTER - Enters the currently specified data parameter into the program's memory.
When H16AC and H16DC is initially powered up, or manually reset, the following default conditions apply:
Forward film direction / 0 preset count selected / 0 total count loaded / shutter is normally closed / no time
exposure / no time lapse. Default exposure time is set to 0.2 sec.
Individual keys when gently pressed down do not complete the key's function till released.
AC POWER SUPPLY:
ITSM/BXAC and MITCHELL16/35AC models require 110 VOLT AC. 60 Hz. power line. Motor speed:
120 RPM. equals 1/6 second exposure time. Use step down transformer to convert 220 VAC to 110 VAC.
50 Hz. line will slow down motor RPM approx. 20%.
DC BATTERY OPERATION:
ITSM/BXDC camera control is powered by 110 VOLT AC line or by 12 Volt DC to 24 Volt DC battery power
supply. The size of the battery depends of extend of use. e.g. For lapse time operation: 1 frames exposed in
15 min. intervals, a 40 Amp. car battery will last approximately one week. In the cold freezing environment
where higher torque is required use 24 VDC power supply.
FOR DC POWER INPUT: use XLB2 type plug and cable provided.
POWER ON/OFF SWITCH
This switch is located in the back panel Use down position for AC input Use up position for DC input.
Use a 4 pin AMP socket. Short pins 2 and 3, this has the same function as RUN key pressed.
MAGAZINE TAKE UP MOTOR: For power on/off output switch use a 1/8" phone
jack, use center tap
for 12 Volt DC power input and body ground.
RESET SWITCH: To erase all read and write memory use the push button switch located in the back panel.
GROWTH LIGHT: Use a 110VAC socket to switch growth light on and off. 2 Amps
max. Light goes on
0.4 seconds before the exposure.
DEFAULT EXPOSURE TIME: ITSM/BXAC and BXDC = 1/6 sec.
#1) For 100 frames (forward):
(PGM) (PRESET TOTAL) (100) (ENTER) (PGM) (RUN)
#2) For 200 time exposure frames at 2.5 seconds:
(PGM) (PRESET TOTAL) (200) (ENTER) - (EXP TIME) (2.5) (ENTER) (PGM) (RUN)
3) To add 10 second time lapse intervals to example #2 above:
(MOD) (LAPSE TIME) (CLR) (10) (ENTER) (MOD) (RUN)
#4) For rotoscoping individual frames in reverse:
(FWD) (SHTR OPEN) (REV) (INDIV)
#5) For 1000 time lapse frames at 60 second intervals, with 5 exposures per
(FWD) (SHTR CLOSED) - (PGM) (PRESET TOTAL) (1000) (ENTER) - (PRESET SHOT) (5) (ENTER) -
(LAPSE TIME) (60) (ENTER) (PGM) (RUN)
Note that the previous exposure time will still exist in this last example.
2 To enter the minutes press the EXPOSURE TIME key. Then the appropriate NUMBER
keys followed by the
ENTER key. Again wait for the display.
3 The seconds can not be entered. Your clock will run continuously until the
ITSM is either reset or powered down.
The exposure cycle will run in the normal fashion described in the instructions.
4 To modify the cycle to run according to time as opposed to frames press the
PGM (PROGRAM) key and
the MODIFY KEY.
5 To modify LED should blink once. Now press the CAP ON key. This will allow
you to enter the time you wish
to have the unit start running first the hour (24 hour format) by pressing the NUMBERS followed by the
Then the minutes in the same fashion. Again the MODIFY LED will blink after the minutes are entered.
6 To enter the time you wish the unit to stop taking exposures press the CAP
OFF key and enter the hours and
minutes in the same fashion as the CAP ON key. If it is past the time for the unit to start you may press the RUN
key to start it manually and the time will take over from there.
STOP KEYS: When the PAUSE key is pressed the unit will still remain in the
run cycle, but the motor will stop
and will allow you to verify any of the data parameters you wish.
The time may be seen by pressing the LAPSE time key and the start and stop
times may be seen by pressing
the VERIFY key followed by the CAP ON or CAP OFF keys. When in the time mode the preset total will have
no effect on the run time cycle.
The following examples demonstrate how to get the ITSM running in the timer mode starting at 7:10 AM
o'clock and ending at 7:30 PM o'clock with a 0.5sec. exposure time and a 60 sec. lapse time. We will say for
now that it is 2:20 PM o'clock when you start this process:
POWER ON FIRST THEN PRESS RESET BOTTOM (Located in the back of the box)
Set clock first - Hours: (PRESET TOTAL) (14) (ENTER) - Minutes: (EXP.TIME) (20) (ENTER)
Program exposure time: (PGM) (EXP.TIME) (0.5) (ENTER)
Program lapse time: (LAPSE TIME) (6) (0) (ENTER)
Set the time to start: (MODIFY) (CAP ON) (7) (ENTER) (10)
