The VMM-T1 is a complete timer/driver system for normallyopen or closed shutter operation. For precision control,flexibility, accuracy, and repeatability, it incorporates every
feature necessary for most applications.
The VMM-T1 offers an exposure and delay interval range from.1ms to 2.8 hours. It also provides three choices for bothinternal timer activating and resetting. In addition to shutter
control from the BNC inputs, these inputs can also becontrolled via a computer serial port (RS-232C). By selecting
the proper address for each unit, up to 8 devices can becontrolled from one serial port.

OPTIONS• 710R-(BNC male to hand held pushbutton switch.) For
remote manual operation of the VMM-T1, this 10’ remote
activate cable is available. The 710R connects to any VMMT1 input BNC connector. Upon depression of the hand heldswitch, the selected input BNC function will be activated. (Afoot activated switch can be substituted for the hand heldtype; please order 710R/F.)• 910RS-(9-pin D-sub female to 9-pin D-sub male.) For
connecting a single VMM unit to a computer’s serial port,
this 10’ interconnect cable is available. The 910RS
connects the RS-232 computer serial port to the RS-232C
input of the VMM-T1.
• 910RSDC-(9-pin D-sub female to 9-pin D-sub male/malemodule.) For connecting multiple VMM units to one
computer serial port, this 10’ interconnect cable isavailable. This cable effectively connects a number of VMM
RS-232C ports to one RS-232 computer serial port, creating
a “daisy chain.” One cable is required for each unit desired
within the chain.
• LVD96 - (“LVDS” Driver/Receiver Adapter.) For applications
requiring an interface between LVDS (Low VoltageDifferential Signaling) and TTL (Transistor Transistor Logic)
signal levels.

VMM-T1 FRONT PANEL
Timer configuration is easy and straightforward
using the VMM-T1. EXPOSURE and DELAY intervals
are selected by simple 4-digit push wheelswitches, the (+) pushbutton increments aparticular digit while the (-) pushbutton
decrements. The number of exposures per trigger
can be selected from 1-99 via the EXP. PRESET 2digit push wheel switch. Zero indicates continuousoperation. The 5 position rotary switches selectthe range for each TIME SELECT push wheelgrouping. LED indicators reveal shutter status at aglance, while the toggle switches easily configure
the VMM-T1 for specific control functions.

Figure 1VMM-T1 REAR PANEL
All main input/output functions can be accessedat the VMM-T1 rear panel, including the115/230VAC input. Manually selectable.
Additionally, BNC connectors allow for quick
termination of TTL command signals, FUNCTION
SWITCHES A-D determine the active state of eachof the BNC inputs (high or low level active).
FUNCTION switch E selects HIGH/LOW status.
Addressable RS-232C control is also available via
the DB-9 connector. The unit’s specific address isselected via the ADDRESS rotary octal switch.
