Introduction
The ED12DSS is the optimal driver for the new UNIBLITZ® N-CAS® DSS Shutter Series. This
device will operate a single DSS shutter or a single NS series bi-stable shutter from a +12 to 24 VDC
power supply. The bi-stable mode only requires power when switching the shutter’s state.
The repeat exposure specification of the ED12DSS is limited by the type of shutter used and the
open/close pulse duration selected by the 4-position piano DIP switch, S1.
Please note that at higher shutter cycling frequencies heat will begin to rise in the shutter coil especially
if the shutter is in an area with limited air flow. This heat can cause premature failure. Please contact
the factory for specific information concerning shutter modifications and/or drive modifications that
may be necessary for operating shutters at their higher frequency. Please note that the shutter output is
fuse protected.
Please see SPECIFICATIONS, GENERAL CHARACTERISTICS, S1 Settings Chart for further
information.
Note: Under certain circumstances multiple ED12DSS drive units can be operated from one power
supply. If the user requirement does not require that shutters open simultaneously, two drivers may be
operated from one supply. For further information and guidance please discuss your particular
application with a Vincent Associates technical service representative.

Start Up
After unpacking your unit inspect for any defects. Upon inspection if a visible defect is found, or a part
(or parts) is missing, notify Vincent Associates immediately.
Prior to the connection of input/output signals to the ED12DSS be sure that:
1. The 5-pin connector of the ED-IOP (power/trigger input connector) is disconnected from the 5-
pin post connector P1 of the ED12DSS.
2. The power supply is in the off position.
3. Set S1 to the pulse duration required for the shutter being used. See SPECIFICATIONS and
Figure 1 elsewhere in this manual for required settings.
4. Connect the Red wire of the ED-IOP harness to the (+) side of a +12 VDC to +24 VDC 1.5A
power supply.
5. Connect the Black wire of the harness to the (-) return side of the power supply.
6. Connect the 5-pin female connector of the ED-IOP onto P1 of the ED12DSS. (The connector is
polarized and can only be properly connected in one orientation)
7. Connect the 203D shutter interconnect cable between the 2-pin P2 connector on the ED12DSS to
the 2-pin connector on the shutter’s flex interconnect.
8. Turn on the power supply.
9. Connect an input signal, active-high TTL to the input BNC.
Be sure to observe Electro-Static Discharge (ESD) anti-static
unpacking procedures when removing the ED12DSS from the
static shielding bag. Improper handling can result in
destruction of the CMOS integrated circuits on the board.
CAUTION

Initial Operation and Testing
The ED12DSS provides the circuitry necessary to drive DSS shutter units.
The on-board microprocessor accepts a pulse with determined exposure time and produces a bi-
stable open and close pulse whose duration is selected by the on-board piano switch, S1. Please see
Figure 1.
When the ED12DSS receives the correct initiating control signal, the shutter will open and close on
command.
Once the ED12DSS receives an input signal, the shutter should open at the rising edge of the input
pulse and close at the falling edge of the input pulse. Please see Figure 2.
If the requirement is to operate the shutter from a switch contact closure, follow this procedure:
1. Connect a wire to pin #5 of the ED-IOP harness, this is the +5 VDC output.
2. Switch the +5 VDC output voltage to the BNC input.
The shutter will open and remain open for as long as the switch contact is depressed. When the +5
VDC is removed from the input, the shutter will close. Please see Figure 2.
After connecting the input and output harnesses, the user selects the open and close pulse duration
using the on-board, 4-position piano switch and connects a user supplied power supply. After the
shutter and TTL input signals are connected, the shutter’s exposure can be controlled via a TTL
square pulse input.
Pulse duration is determined by exposure time.
The ED12DSS can be easily integrated into OEM applications where a +12 to +24 VDC power
supply is available.
Please read the entire manual carefully before attempting to operate the unit.

Fuse Replacement
1. F1 is a 0.25A fast-acting SMT fuse that is soldered to the ED12DSS PCB. This fuse is non-
replaceable.
2. F2 is an SMT user-replaceable fuse rated for 0.75 A, 125 V, time lag.
3. This fuse can be removed and replaced in the field. Fuses can be procured from the
manufacturer.
Be sure to observe Electro-Static Discharge (ESD) and
anti-static procedures when replacing the fuse.

Maintenance
Proper care and maintenance of the ED12DSS should be taken as with any sensitive electronic
instrument.
There are no user-serviceable parts on the ED12DSS except for F2.
Although the stability of the drive voltage is checked and calibrated prior to shipment, it may become
necessary to make some minor adjustments to the operating systems of the ED12DSS over time.
It is highly recommended that if a problem is suspected with the unit that it be returned to the factory for
checkout, proper adjustments and calibration. Failure to do this may damage the unit’s circuitry and/or
functionality and will void the factory warranty.
Inspection
Inspect the ED12DSS for damage, wear, and missing parts. If the unit appears to show signs of damage,
it should be checked thoroughly to verify correct operation and performance. If damage is suspected,
please return the unit to the factory for repair – there are no user-serviceable parts on the board.
If there is a significant build-up of dust or other material, follow the cleaning procedure below.
Cleaning Procedure
Do not use any tools to brush or scrape away accumulated materials.
Do not use any liquids to clean the board.
Simply use low-pressure air to blow away any dust.
There is no other cleaning required.
