* THIS IS A DISCONTINUED PRODUCT*
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.

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
damage to this product or other property.
