The Vincent/UniBlitz VMM-T1 is a precision shutter driver and timer controller engineered for direct command of all UniBlitz shutter types. It delivers crystal-controlled exposure and delay timing with 0.5% accuracy and 1 ms resolution, supporting both normally open and normally closed operation modes. The unit accepts external TTL pulse triggers via BNC or internal timer control, with timing intervals spanning 0.1 ms to 9999 seconds. Independent delay timers enable pre-exposure or post-exposure control, while selectable pulse energy supports VS35 and VS45 shutter variants. The VMM-T1 replaces the T132 controller and scales across multiple units via daisy-chained RS-232 addressing.
Technical Specifications

– Compatibility & Integration
The VMM-T1 controls the entire UniBlitz shutter product line and interfaces with external systems through TTL command signals, RS-232 serial control, and synchronization outputs. Eight units may be networked and individually addressed via RS-232 for multi-shutter applications.
