Vincent / UniBlitz VMM-D1 Shutter Drive Controller

The Vincent/UniBlitz VMM-D1 Shutter Drive Controller is a precision instrument for reliable control of UniBlitz shutters across scientific, imaging, and industrial applications requiring accurate optical path timing and positioning. This controller replaces the legacy D122 model and supports three selectable operational modes via key switch, accommodating diverse triggering scenarios from external pulse sources to contact closure detection. The unit accepts control inputs via BNC TTL, switch contact, RS-232C serial (8 addressable units), or remote actuate cable, and outputs exposure pulses, electronic synchronization signals, and configurable AUX control. All BNC inputs and outputs are TTL compatible with selectable active-high or active-low logic, supporting both rising and falling edge triggering. The VMM-D1 operates in Standard Shutter mode for external pulse or contact-driven exposure, Line Interrupt mode for AC power loss detection with manual/remote reset capability, and DC Interrupt mode for external switch contact break detection with similar reset requirements. It supports normally open and normally closed shutter configurations with pulsed on/pulsed off exposure control.

– Key Features

• Three operational modes selectable via key switch
• Multiple input control options: external pulse (BNC, TTL), switch contact closure, RS-232C serial, remote actuate cable
• Output signals: exposure pulse (BNC, TTL), electronic synchronization (BNC, TTL), AUX (RS-232C configurable)
• Reset via external pulse, front panel pushbutton, or remote actuate cable
• TTL logic configurable for active-high or active-low operation
• Supports rising and falling edge triggering on BNC inputs
• Manual voltage selection eliminates auto-switching requirements of predecessor D122

– Compatibility & Integration

The RS-232C interface addresses up to 8 independent units from a single computer port, enabling multi-shutter systems under centralized serial control. Flexible input and output configurations accommodate retrofit installations alongside existing trigger infrastructure.
