Getting Started
Features
The VMM-T1 Shutter Driver/Timer replaces the T132 controller. The VMM-T1 contains nearly all
of the features of the T132 plus some new features which enhance the unit’s 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
connector (DB-9 female) and the user can select an address for each unit at the rear panel
through the use of the ADDRESS switch.
•Switching capability on all BNC input jacks to provide either an active-high or active-low logic
trigger level.
•An Auxiliary (AUX) output that is the DELAY timer output, on a three-pin terminal located on
the rear panel. This terminal also includes pins for +5VDC and Ground.
•A GATE INPUT which allows the user to select a single or multiple trigger signals from a
stream of trigger signals.
•An EXPOSURE PRESET (EXP PRESET) control which combines the functions of the
NORM/CONT switch of the previous Model T132 and an exposure counter. The user can pre-
select a number of exposures per trigger signal from 1 to 99. By selecting the EXP PRESET to
00 the unit will re-trigger continuously.
•A user-configurable AC input module. This AC input module includes the AC power cord input
receptacle, power switch, dual 3AG, 0.5A time-lag (slo-blo) line fuses (For 115 VAC
operation), line voltage change-over fuse block, and line filter. Dual 3AG, 0.25A time-lag (slo-
blo) line fuses for 230 VAC operation are supplied.

Introduction
The UNIBLITZ VMM-T1 is 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
has a range from 0.1msec to 9999 seconds. Four-digit pushwheel switches provide exceptional
resolution for use in a multitude of shutter applications, ranging from holography to microscopy. The
VMM-T1 incorporates a state of the art shutter driver and relies on the user’s input signal to determine
exposure and frequency.
Another 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. 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”, 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 and 99 the shutter will trigger
for the number of exposures selected.
The VMM-T1 contains an addressable RS-232C input. By using the Model 910RSDC daisy-chain
cable, multiple controllers can be connected and controlled. Eight separate addresses are available
which allows up to eight units to be individually controlled by a single computer serial port.
The patented driver design of the VMM-T1 allows the controller to operate all shutter types in the
UNIBLITZ product line.
A Model 710C, 7-pin female to 7-pin male (3 meter length), shutter interconnect cable is also included
with each unit.
Start Up
After unpacking the unit, inspect for any obvious defects and that all manufacturer supplied materials
are present.
If a problem is found or a part (or parts) is missing, please contact Vincent Associates immediately for
problem resolution. Do not attempt to connect the unit if defects or damage are noted until Vincent
Associates has been contacted and the problem resolved.
After the initial inspection the unit is ready to use. To properly install and power on the VMM-T1,
please follow the procedure below.
1. Check for proper electrical connections. Please note the label covering the AC input module. It
is there as a reminder to re-configure the AC input module if the unit requires operation at
230VAC. The VMM-T1 is shipped with the proper fuses for 115 VAC operation installed (two
3AG, 0.5A time-lag (slo-blo)). See “Voltage Change” instructions elsewhere in this manual.
CAUTION
This label must be removed prior to inserting the power cord into the
AC input receptacle regardless of which AC voltage level is used.
Caution statements identify conditions or practices that could result in
