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.
