The VMM-T1 is a complete timer/driver system for normally open 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. The VMM-T1 also provides three choices for both internal timer activating and resetting. In addition, the shutter can be controlled from the BNC inputs, these inputs can also be controlled via a computer serial port (RS-232C). By selecting the proper address for each unit, up to 8 devices can be controlled from one serial port.
