Page 8: Preface
Preface This Manual provides information for the VCM-D1 Shutter Driver. The manual contains the following chapters: • Getting Started contains a brief product description, information needed to power on the drivers, fuse replacement and voltage change information, and a brief procedure to verify that it functions.
Page 9: Getting Started
Features The UNIBLITZ VCM-D1 replaces the VMM-D1 controller for those customers requiring CE/UL/CSA certification. The VCM-D1 contains all of the features of the VMM-D1, in addition to some new features, which enhance the units’ capability in even more demanding applications.
Page 10: Introduction
One feature of the VCM-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.

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 VCM-D1 has been shipped with the proper fuses for 115VAC operation (3AG ½ A “T” type - time-lag).

SYNC output and SYNC ACTIVE LED. The remainder of the VCM-D1 systems will not be affected. In addition the SYNC system can be disabled by sliding the “G” FUNCTION switch to the upper position.

CONTROL #5 Output. When interrupt is activated, this normally low output is high until reset deactivates the interrupt. CONTROL #6 AUX Output. The VCM-D1 AUX output is an active low pulse output that can be toggled TTL high and low from commands presented to the RS- 232C control input.
Page 16 10. N.O./N.C. Toggle switch. The position of this switch determines shutter status BEFORE a trigger signal is received by VCM-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.

VCM-D1. Therefore, this input can be used to “pick” a pulse or pulses from a series of trigger pulses presented to the TRIGGER INPUT. This input must be used in conjunction with the TRIGGER INPUT.
Page 20 11. PULSE OUTPUT BNC. The duration of this pulse is equal to the duration of the shutter exposure pulse. This output can be used to daisy chain VCM-D1 units together. A TTL exposure pulse input to the PULSE INPUT BNC will appear at the PULSE OUTPUT BNC. Note toggling the N.O./N.C.
Page 21: Operating Basics
TRIGGER INPUT is selected to the active low state (function switch “A” down position). When a stream of trigger pulses is input to the TRIGGER INPUT and the GATE INPUT is in the high state (TTL logic “1”, +5V), the trigger signals will operate the VCM-D1 as described in the VCM-D1 User Manual...
Page 22: Gate Timing Diagrams
(See Figure #5B.) Therefore, the number of trigger pulses input (or GATE INPUT duration) is equal to the trigger period times the number of exposures desired. The VCM-D1 TRIGGER INPUT opens the shutter with the first pulse presented to the input and closes the shutter on the subsequent pulse.
Page 23: Mode Selection
The key can be removed in any position thus preventing the switch from inadvertently being changed while in operation. This will ensure that if an interrupt is set, the shutter will not return to its original state until the VCM-D1 unit is reset (by any of a number of methods).

All other pins not used. Be sure to connect the Tx pin, Pin 3 from the IBM 9-Pin D-Sub (or Pin 2 from the 25-Pin D-Sub) male connector to the Rx pin, Pin 5 of the VCM-D1 RJ-45 INPUT connector (located at the rear panel) for proper operation. Connect all other functions as indicated above.

Page 28: Shutter Frequency Of Operation
VS25 shutter (with Teflon shutter blades) has a minimum exposure pulse of 6ms, if the exposure or pulse width presented to the VCM-D1’s PULSE INPUT is less than 6ms, the shutter may not open fully. If the unit still does not operate properly, when using the proper pulse width, please notify Vincent Associates immediately.

Page 31: Maintenance
Proper care and maintenance of the unit should be taken as with any electronic instrument. Inspection and Cleaning Inspection and cleaning describes how to inspect and clean the VCM-D1 . Inspection and cleaning are preventative maintenance. Preventative maintenance, when done regularly, may prevent driver malfunction and enhance its reliability.
Page 32: Inspection - Exterior
– no user serviceable parts inside. Cleaning Procedure - Exterior 1. Remove loose dust on the outside of the VCM-D1 with a lint free cloth. 2. Remove remaining dirt with a lint free cloth dampened in a general purpose detergent-and-water solution.
