INTRODUCTION
The DM412 Drive Module interfaces the smallest aperture shutter in the UNIBLITZ ®
line, the UHS1T2 High Speed Shutter, to the VMM-D1 or VMM-T1 shutter driver
units. Operation of the DM412 is simple and straightforward. All activate functions are
supplied through the VMM-D1 or VMM-T1 shutter drivers. The only control integral to
the DM412 is the NORM\HIGH switch, which allows “on-the-fly” selection between
the normal (NORM) and the (HIGH) speed modes. The CONTROL BNC allows TTL
(active low) or remote switch (710R) to electronically select the normal and high-speed
modes, providing greater flexibility.
MAINTENANCE
Although the stability of the timing and drive voltage is assured and calibrated prior to
shipment, it may become necessary to make some minor adjustments to the operating
systems of the DM412 and the VMM-T1 or VMM-D1 over time.
It is highly recommended that if you suspect a problem with your unit that it be returned
to the factory for proper adjustments and calibration. The units’ complicated circuitry
will be damaged and/or not function as specified if adjusted improperly.
Proper care and maintenance of the unit should be taken as with any electronic
instrument.
WARRANTY
Great care has been taken to ensure that our products are free from defect when shipped.
Defective units will be replaced or repaired at no charge, excepting transportation
charges, if returned within 90 days from the date of shipment. Vincent Associates will
consider the return of unused equipment if returned within 30 days from the date of
shipment subject to a 20% restocking charge. This offer does not apply to used or
damaged equipment.

between the HIGH and NORMAL speed modes. A low level input places the
unit into the NORMAL speed mode. A high level places the unit back to the
HIGH speed mode.
2. NORM/HIGH Switch. Allows manual switching between the HIGH and
NORMAL speed modes.
3. POWER Indicator.
4. SHUTTER. DM412 9-Pin female connector to mate with 9-Pin male connector
of the 10’ shutter interconnect cable provided with the control.
5. CONTROLLER. DM412 7-Pin male connector to mate with 7-Pin female
connector of the 10’ interconnect cable provided with the VMM-D1 or VMM-
T1 controller. This cable provides power and control for the DM412 control unit.
6. FUSE B. Replace with 5x20mm 800mA slow blow fuse.
7. FUSE A. Replace with 5x20mm 800mA slow blow fuse.

OPERATING INSTRUCTIONS
After unpacking unit, inspect for any defects. If upon inspection a problem is found,
notify Vincent Associates immediately.
After initial inspection, the unit is ready for use. Please read the following operating
instructions. Improper input/output connections to the unit may cause irreparable
damage.
The DM412 receives power from VMM-D1 or VMM-T1 driver. Connect the DM412
as per drawing #L-0171. Follow the power up procedure as described in the VMM-
D1/VMM-T1 users manual. Once power is on, the DM412 POWER LED will
illuminate. Place the NORM/HIGH switch in the NORM position. Place the
N.O./N.C. switch (of the VMM-D1 or VMM-T1) to the N.O. position. The shutter will
open and remain open until either the N.O./N.C. switch is returned to the N.C. position
or the NORM/HIGH switch is returned to the HIGH position. Note, the SYNC LED
and the SHUTTER LED (of the VMM-D1 or VMM-T1) will illuminate when the
shutter goes to the open position to indicate the presence of a shutter activate signal and
that the shutter has opened respectively.
In the HIGH-speed mode, a signal to the VMM-D1 or VMM-T1 will trigger the
UHS1T2 for 300µsec. only. The shutter cannot be held open in this mode. For example,
with the DM412 in the HIGH mode, switching the N.O./N.C. switch to the N.O.
position the shutter will open for 300µsec. (typical A - G time). The SHUTTER LED of
the VMM-D1 or VMM-T1 will illuminate, however, the SYNC LED will only flash
indicating a high-speed exposure. Please note, the typical shutter timing for each of the
modes respectively is enumerated in the attached UHS1 data sheet.
When operating the UHS1 shutter from a pulse source (through the VMM-T1 or VMM-
D1) the minimum pulse width, in the NORM mode, is 600µsec. If the input pulse width
in this mode is set to less than 600µsec., the shutter response will be indeterminate. If the
input pulse is greater than 600µsec., the shutter will be held open for the duration of the
pulse and therefore, in this mode, is programmable. Please note, though the minimum
input pulse in the NORM mode is 600µsec., the shutter response (A - G window time)
will typically be1.0msec (see UHS1 data sheet for typical timing data). In the HIGH
speed mode the shutter exposure is 300µsec (proper exposure pulses are derived within
the DM412), regardless of the duration of the input pulses to the VMM-D1 or VMM-T1.
Therefore, the minimum input pulse or trigger width, input to the VMM-D1 or VMM-
T1, will be as enumerated in the SPECIFICATIONS section of the VMM-D1 or
VMM-T1 manual.
Please review the Caution section on page #21 in the VMM-D1/VMM-
T1 manual for information concerning fuse inspection and replacement.
The UHS1 can be operated as any typical shutter in the NORM speed
mode. Therefore, the shutter can also be controlled via the RS-232
interface. Please review SYSTEMS OPERATIONS section on page #22
in the VMM-D1/VMM-T1 manual.

• 1mm diameter aperture
• Fastest shutter in the UNIBLITZ®line of electro-
programmable shutters.
• 300µsec. total exposure time in the (HIGH) speed
mo de.
• 100µsec. rise time.
• Activated by an electronic pulse through shutter
driver module, the DM412, included.
• Exposure repetition rate continuously variable
from DC-400Hz.
• Non-resonant design allows instantaneous changes in
repetition rate and duty cycle in the normal (NORM)
mo de.
• No optical surface when open provides 100%
transmittance
The UHS1 supersedes the LS2 as the fastest shutter in
Vincent’s UNIBLITZ line. As with the LS series, the
UHS1 is specially suited for laser use, with applications
including low level chopping, high speed switching, pulse
gating and selection, and modulation to 400 Hz. In the
high speed mode (HIGH) the UHS1 produces a total
exposure pulse of 300µsec! This speed is
unprecedented in Vincent type instrumentation shutters.
In the normal speed mode (NORM) the shutter is
programmable, and activated by an electronic pulse
generated by Vincent’s drive module, the DM412. This
module is included with the UHS1, and will interface with
the D122 and T132 controllers. The DM412 converts the
specialized shutter drive outputs into the voltage pulses
necessary for proper operation of the UHS1.
DM412 Drive Module:
Operation of the DM412 is simple and straightforward. All
activate functions are supplied through the D122 or T132
shutter drivers. The only controls integral to the DM412
are the NORM/HIGH switch which allows “on the fly”
selections between the normal (NORM) and high (HIGH)
speed modes. The CONTROL BNC allows TTL (active
low) or remote switch (710R) to electronically select the
normal and high speed modes, providing greater
flexibility.

The question regarding enhancement of shutter speed with the application of user
supplied lubricants has been repeatedly asked. It is our experience that lubricating
the shutter blades will actually slow the shutter down and eventually render the
shutter inoperable. UNDER NO CIRCUMSTANCES SHOULD ANY TYPE OF
LUBRICANT BE APPLIED TO THE SHUTTER BLADE AREA.
