Getting Started
Features
The UNIBLITZ VMM-D1 and the VMM-T1 replace the D122 and T132 controllers
respectively. The VMM-D1 and the VMM-T1 contain nearly all of the features of the D122
and T132, in addition to some new features, which enhance the units’ capability in even more
demanding applications.
These new features include:
• An addressable RS-232 input. Eight units can be daisy chained together via the RS-232
input and the user can select an address for each unit at the rear panel.
• Switching capability on all input BNC inputs to either an active high or an active low, logic
trigger level.
• An AUX (auxiliary) output that can be toggled high to low and low to high by RS-232
commands (the VMM-D1 only).
• An AUX (auxiliary) output that is now the DELAY timer output (the VMM-T1 only).
• A GATE INPUT which will allow the user to select a single (or multiple) trigger signal(s)
from a stream of trigger signals.
• A LOCAL/REMOTE switch which will effectively "disconnect" all input signals from the
controller allowing the user to manually control the shutter without the need to remove the
signals from the BNC inputs or the terminal strip - located at the front panel (the VMM-D1
only). RS-232C signals are also disabled in the LOCAL position.
• An EXP. PRESET control, which combines the functions of the NORM/CONT switch (of
the T132) and an exposure counter. The user can pre-select a number of exposures per
trigger signal from 1-99. By selecting the EXP. PRESET to 00, the unit will re-trigger
continuously (the VMM-T1 only).
• A manually re-configurable AC input module. The 115/230VAC input is no longer
automatically switched (as with the D122 and T132). The user will need to manually re-
configure for 230VAC operation. This AC input module includes the AC power cord
input connector, power switch, dual .5A SB 3AG line fuses, line voltage switch over fuse
holder, and line filter.

Introduction
The UNIBLITZ VMM-D1 and VMM-T1 are capable of controlling all shutter types in
the UNIBLITZ product line. The VMM-T1 incorporates two precise timers to control shutter
exposure and delay intervals. Each timer range is from .1ms to 9999sec. Four digit pushwheel
switches provide exceptional resolution for use in a multitude of shutter applications, ranging
from holography to microscopy. The VMM-D1 incorporates a state of the art shutter driver
while relying on the users input signal to determine exposure and frequency.
One feature of the VMM-T1 is the PRE or POST exposure delay. The PRE/POST
toggle switch allows the user to actuate the shutter immediately upon receipt of a trigger signal
or delay the EXPOSURE for a predetermined period. The period of the DELAY interval is
determined from the front panel DELAY TIME SELECT. The DELAY signal is provided to
the AUX output terminal located at the rear panel of the control. In addition to the PRE/POST
DELAY, the VMM-T1 can re-trigger itself continuously to provide low level chopper control.
By selecting the EXP. PRESET pushwheel switch to “00”, once triggered, the DELAY interval
control acts as the recycle interval to determine the exposure frequency. The unit will run
continuously until reset. By selecting any value between 01-99, the shutter will trigger for the
number of exposures selected.
One feature of the VMM-D1 is the selection of interrupt mode. With the mode switch
in the “A” position, the unit will disable itself upon an AC line loss. When power is restored,
the unit will remain disabled until reset. In the “B” position the unit will become disabled when
a DC voltage level is removed from the interrupt input. When the input is restored, the unit will
remain disabled until reset. The STD mode will bypass the interrupt capability. This mode
selection makes the VMM-D1 more versatile for applications where the shutter must not re-
open until acted upon by the user.
Both models contain an addressable RS-232 input. By using our daisy chain cable (the
910RSDC, purchased separately) multiple controllers can be connected together. Eight
separate addresses allow up to eight units to be individually controlled via one computer serial
port.
The patented driver design of the VMM-D1 and VMM-T1 allows the controller to operate all
shutter types in the UNIBLITZ product line.
A l0ft. 7-pin female to 7-pin male shutter inter-connect cable is also included with each unit
(the 710C).

Start Up
After unpacking your unit inspect for any defects. If upon inspection a problem is
found, or a part (or parts) are missing, notify Vincent Associates immediately.
After the initial inspection the unit is ready to use. To properly install and power on the
VMM-D1 or VMM-T1, perform this procedure.
1. Check that you have the proper electrical connections. The rear label, which covers the AC
input module, is there to remind you to manually configure the AC input module if the unit
requires operation at 230VAC. See “Voltage Change” instructions. THIS LABEL
MUST BE REMOVED PRIOR TO INSERTING THE POWER CORD INTO THE
AC INPUT CONNECTOR REGARDLESS OF WHICH AC VOLTAGE LEVEL IS
USED.
2. Check the line fuses to be sure they are the proper rating. The VMM-D1 and VMM-T1
have been shipped with the proper fuses for 115VAC operation (3AG .5A time-lag). For
230VAC operation, change line fuses to the 5mm x 20mm .25A time-lag (supplied w/unit,
packaged separately). See “Line Fuse Replacement” instructions.
3. Be sure the AC module power switch is toggled to the “0” position and the power end of
the line cord is not connected to the AC line. Then connect the opposite end of the
supplied line cord to the rear panel AC module connector. Be sure the cord is inserted
completely into the AC module connector.
4. Connect the power end of the line cord to the AC line. Power unit ON by toggling the AC
module power switch to the “1” position. Power LED indicator will illuminate.
Line Fuse Replacement
1. Have handy a small flat-bladed screwdriver or similar tool and refer to Figure #1.
WARNING. To avoid injury or death, unplug the line cord from the
line voltage power source before continuing.
2. Set the VMM-D1 or VMM-T1 unit so that the rear panel is facing you.
3. BE SURE THE LINE CORD IS DISCONNECTED FROM THE LINE VOLTAGE
POWER SOURCE. Unplug the line cord from the AC module connector. You cannot
proceed with this procedure without removing the line cord from the VMM-D1/T1
control unit.
4. Using the small flat bladed screwdriver or similar tool; insert the tool into the cover door
slot; pry open cover door.
5. Using the same tool; insert the tool into the fuse holder slot; pry out the fuse holder block.
6. Remove defective fuse(s); replace with new fuse(s) and replace fuse holder into housing;
close the cover door.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Voltage Change
WARNING. To avoid injury or death, unplug the line cord from the
line voltage power source before continuing.
1. Repeat steps 1-5 in “Line Fuse Replacement” instructions and refer to Figure #1.
2. Rotate the fuse holder block 180°; if changing to 230VAC, replace fuses with two 5mm x
20mm .25A time-lag fuses. (Be sure to change fuses back to 3AG .5A time-lag fuses when
changing back to 115VAC).
3. Replace fuse holder block and close the cover door. The desired voltage will be indicated
and appear in the cover door window.

Initial Operation and Testing
The VMM-D1 and VMM-T1 will operate from 115VAC or 230VAC (50-60Hz), this
is manually selectable. *PLEASE BE SURE THAT THE UNIT IS PROPERLY SET UP
FOR THE LINE VOLTAGE TO BE USED.* Once the line cord has been attached to unit
and connected to properly grounded wall receptacle, the unit may be operated. *BE SURE
POWER SWITCH IS IN THE OFF POSITION BEFORE CONNECTING PLUG TO
LINE. ATTACH LINE CORD TO THE UNIT FIRST BEFORE PLUGGING INTO
THE AC POWER SOURCE.* See “Start Up” section.
Insert the seven pin male connector of shutter interconnect cable into seven pin female
receptacle at rear of unit labeled SHUTTER. Connect the seven pin female connector of shutter
interconnect cable to seven pin male connector on shutter to be driven.
Place POWER switch to the ON “1” position, the POWER LED will illuminate. Place
the N.O./N.C. switch into the N.O. position. The shutter will open and remain open until the
switch is returned to the N.C. position. The SHUTTER ACTIVE LED will illuminate when
this switch is in the N.O. position.
All UNIBLITZ drivers provide the circuitry necessary to support shutters equipped with
the solid state synchronization option. Simply plug the shutter interconnect cable into the
driver. If your shutter is equipped with this option the green LED, labeled SYNC ACTIVE,
will illuminate when the shutter is in the open position. In addition, the active low SYNC
output will change to the low state when the shutter is open. The absence of the solid state
synchronization option will only inhibit the operation of the SYNC output and SYNC ACTIVE
LED. The remainder of the VMM-D1 and VMM-T1 systems will not be affected.
See specifications and operator controls for additional operational information
concerning other systems of the VMM-D1 and VMM-T1
CAUTION
Should the shutter and/or control not respond as described previously, be sure line cord is installed into
the receptacle and connections to the shutter are made properly. Note that the shutter output is also fused (located
at the front panel - .6A time-lag). TURN OFF THE UNIT AND REMOVE THE PLUG FROM THE AC
SOURCE BEFORE CHECKING FOR BLOWN FUSES. Be advised, a visual inspection of a fuse is usually
NOT an adequate test to determine if a fuse failure has occurred. Use a DMM (Digital Multi-Meter) or equivalent
test device to determine fuse continuity. Also, particular shutter units respond to different minimum pulse widths.
For example, a standard VS25 shutter has a minimum exposure pulse of 6ms, if the timing is set for an exposure
pulse width less than 6ms, the shutter may not open fully. If the unit still does not operate properly, please notify
Vincent Associates immediately.

VMM-D1 Front Panel Operator Controls
Description
(Refer to Figure #2)
1. CONTROL Terminal block. The five position terminal block referred to on the driver (and
throughout this manual) as CONTROL provide access to several of the input and output
connections for external operation of your driver. Each terminal is explained below:
a. CONTROL #1 Output. +10VDC provided for remote switching applications or control
circuits.
b. CONTROL #2 Pulse In. Active high input to control shutter exposure for duration of
positive pulse, or electronic or mechanical switch contact closure. Shutter will follow pulse
and frequency applied to this input. (This will operate the same as the PULSE IN BNC set
to the active high mode.)
c. CONTROL #3 GND. This convenient ground point allows user to connect input or output
signals to ground (common) the VMM-D1 circuit.
d. CONTROL #4 Input. DC interrupt voltage. With key switch set to mode B, the interrupt
will be activated when input DC voltage (+8VDC min.) is disrupted via a switch, transistor,
or similar method. This input is for DC voltage only.
e. CONTROL #5. Output. When interrupt is activated, this normally low output is high until
reset deactivates the interrupt.
2. MODE Keyswitch. The position of the key switch sets the mode of interrupt. The interrupt
switch disables the shutter driver when a voltage interrupt is detected, either AC or DC. Upon
reset, the shutter will return to the position set by an external input or the position of the
N.O./N.C toggle switch.
a. A(AC interrupt mode). Prevents the driver from re-opening the shutter immediately
upon power-up if the line voltage were to be interrupted. The driver remains disabled until
user supplies reset by specified means.
b. B(DC interrupt mode). When the key switch is in Position B the driver will become
disabled when it detects that the DC input voltage at CONTROL #4 has been removed or
disrupted. When the voltage level is re-applied, the driver remains disabled until reset. The
DC input voltage is supplied (from CONTROL #1) or from an external source, determined
by the user.
c. STD The STD mode bypasses the driver's interrupt capabilities. CONTROL #4 and
CONTROL #5 become inactive. The VMM-D1 will not remain disabled after a disruption
in line voltage.
3. SYNC. ACTIVE LED indicator. Indicates status of Solid State Sync. output. The green LED
is illuminated when shutter's electronic sync. is activated. (This LED functions only if the
shutter used is equipped with the Solid State Sync. system.)
4. DRIVER ACTIVE LED indicator. This LED indicates when the internal shutter driver circuit
input has an active signal present.
5. DISABLED Indicator. Indicates that one of the two interrupt modes (mode A or mode B) has
disabled the driver. LED is off after reset, and STD operation.
VMM-D1 & VMM-T1 User Manual 15
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

6. RESET Momentary Pushbutton Switch. Resets VMM-D1 disabled by interrupts (mode A or
mode B) and returns shutter to the position determined by the N.O./ N.C., or the status of the
PULSE input. (The TRIGGER flip-flop is also reset. If the shutter had been activated by this
input the shutter will close after a reset pulse.) Please note if an open command is sent to the
RS-232 input, a reset command will not clear the RS-232 output and the shutter will not close.
You must send a close command to allow the shutter to close. If you wish to have the shutter
close (or return to the state as set by the N.O./N.C. switch) with a reset command or the
RESET switch, you must open the shutter with a trigger command.
7. LOCAL/REMOTE Toggle switch. When in the LOCAL position all inputs to the unit are
effectively "disconnected” allowing the user to manually control the shutter without the need to
remove the signals from the BNC inputs or the terminal strip (located at the front panel). In the
REMOTE position, the unit will function normally. RS-232C signals are also disabled with
this switch in the LOCAL position.
8. POWER LED indicator.
9. SHUTTER FUSE. Replace with 5mm x 20mm .6A time-lag fuse. This fuse may fail if the shutter is
operated at an excessive frequency and duty cycle to protect the coil from premature failure. If the
operation of the shutter used is causing “nuisance blowing” of this fuse, please contact technical
support to discuss your application.
10. N.O./N.C. Toggle switch. The position of this switch determines shutter status BEFORE a trigger
signal is received by VMM-D1. In the N.C. position the shutter will be activated open by an input pulse
signal. In the N.O. position the shutter will be activated closed. The N.O./N.C switch acts to invert the
shutter operation. Any RESET command will return the shutter to the position determined by the
N.O./N.C. switch. Please note if an open command is sent to the RS-232 input, a reset command will
not clear the RS-232 output and the shutter will not close. You must send a close command to allow the
shutter to close. If you wish to have the shutter close (or return to the state as set by the N.O./N.C.
switch) with a reset command or the RESET switch, you must open the shutter with a trigger command.

VMM-T1 Front Panel Operator Controls
Description
(Refer to Figure #3)
1. DELAY TIMER SELECT. Four pushwheel switches determine the DELAY timing range. The
total delay interval will be the product of the DELAY TIMER SELECT and DELAY
MULTIPLIER. (Each depression of the (+) key increases each digit by one, the (-) key
decreases each digit by one.)
2. DELAY LED indicator. LED indicates when DELAY timer is active.
3. EXPOSURE TIMER SELECT. Four pushwheel switches determine the EXPOSURE timing
range. The total exposure interval will be the product of the EXPOSURE TIMER SELECT and
EXPOSURE MULTIPLIER. (Each depression of the (+) key increases each digit by one, the (-
) key decreases each digit by one.)
4. EXPOSURE LED indicator. LED indicates when EXPOSURE timer is active.
5. EXPOSURE MULTIPLIER switch. Clockwise rotation of the 5 position rotary switch
increases the magnitude of the EXPOSURE interval by a factor of ten.
6. EXP. PRESET SELECT. Two pushwheel switches determine the number of exposure cycles
the unit will count up to per trigger input. A setting of “00” allows the unit to run continuously
until reset. In the “00” or continuous setting, the time between exposures is determined by the
DELAY time interval.
7. SYNC. ACTIVE Indicator. LED indicates the status of the Solid State Sync. system. LED is
illuminated when the shutter's electronic sync. is active. (This LED functions only if the
shutter used is equipped with the Solid State Sync. system.)
8. DRIVER ACTIVE Indicator. LED indicates when the internal shutter driver circuit input has
an active signal present.
9. ACTUATE Switch. Depress this momentary pushbutton switch to trigger the VMM-T1
EXPOSURE and DELAY timers from the front panel.
10. RESET Switch. This momentary pushbutton switch inhibits all functions of the unit. Depress
this switch to reset both the EXPOSURE and DELAY timers, and return all outputs to their
original state. Shutter state will be returned to the status set by the N.O./N.C. switch. Please
note if an open command is sent to the RS-232 input, a reset command will not clear the RS-
232 output and the shutter will not close. You must send a close command to allow the shutter
to close. If you wish to have the shutter close with a reset command or this RESET switch, you
must open the shutter with a trigger command. (The shutter will either close, upon reset, or
return to the state as set by the N.O./N.C. switch.)
11. PRE/POST Toggle Switch. Position of this switch determines if DELAY interval occurs
before (PRE) or after (POST) the EXPOSURE interval. The PRE position delays the start of
the shutter EXPOSURE interval until the end of the DELAY interval. In the POST mode the
DELAY timer is triggered at the conclusion of the EXPOSURE interval. In PRE or POST the
DELAY (AUX) output will go high for the duration of the DELAY interval when the DELAY
timer is active, (the VMM-T1 only).
12. POWER LED Indicator.
