T132 REAR PANEL OPERATOR CONTROLS
(Refer to Figure #4)
14. RESET. Active-low input. Inhibits all T132 functions on the falling edge of an external reset pulse.
Both EXPOSURE and DELAY are reset, in addition to the RS-232 controller.
15. PULSE OUT. Active-low output. Normally high output goes low and remains low while the shutter is
energized. This output can be used for daisy chaining T132 units together.
16. TRIG. Active-low input. Falling edge starts EXPOSURE and DELAY sequence. This input provides
access to the T132 timer via a negative going pulse supplied from an external source.
17. PULSE IN. Active-low input. This input will bypass the internal timer and allow the user to access the
T132 shutter drive circuit. Thus the shutter will be energized when this input pulse is Active-low.
18. SYNC. Active-low output for shutters equipped with Solid State Sync. system. The shutter's internal
sync. circuit sets a low output at this BNC connector when the shutter's sync. is activated.
19. CONTROL. The five-pin connector terminal referred to on the driver (and throughout this manual) as
CONTROL provides access to several of the input and output connections for external operation of your
driver. Each terminal is explained below.
CONTROL #1. Active-high input. TRIGGER. The rising edge of a trigger signal starts EXPOSURE
and DELAY sequence. This input provides access to the T132 timer via a positive going pulse from
an external source.
CONTROL #2. Active-high input. RESET. The rising edge of a reset signal will inhibit all T132
functions. Both EXPOSURE and DELAY timers will be reset.
CONTROL #3. Active-high input. PULSE IN. This input will bypass the internal timer to allow
direct access to the T132 shutter drive circuit. The shutter will be energized while this input is high.
CONTROL #4. +5VDC output. Supplies reg5VDC level for external switching or to control
circuits req5VDC.
CONTROL #5. GND. This convenient ground point allows the user to connect input or output
signals to ground common to the T132 circuit.
20. SHUTTER. 7-Pin female connector to mate with 7-pin male connector of 10' shutter interconnect
cable provided with the control.
21. 115VAC/230VAC. Line Voltage connector. Mates with female plug on the line cord provided with
T132. Can be directly connected to the 115VAC or 230VAC line.
22. HIGH/LOW Switch. Pulse energy toggle switch. Switch to HIGH position for operation of VS35
shutters only. Use LOW position for all other
UNIBLITZ
shutters.
