The VMM-D3 is a three-channel shutter driver capable of controlling up to three Vincent shutters independently. The compact design puts three individual shutter drivers in a single streamlined system. Active high-level logic inputs allow independent shutter control. One single input will activate all channels simultaneously. Active low-level logic outputs are available to monitor the status of each individual synchronization system output. One single output is available to monitor when all shutter synchronization system circuits are active. An addressable RS-232C serial input is also available to control these inputs via a computer serial port. By selecting the proper address for each unit, up to 8 devices can be controlled from one serial port. In this way, 24 individual shutters can be controlled from one computer COM port!
