## Front Panel Layout Simple and straightforward controls allow the VMM-D3 to be easy to use and configure. LED indicators reveal each shutter’s status at a glance. Three fuse holders with .6A slow blow fuses, accessible at the front panel for ease or replacement. N. O./N. C. switches allow manual shutter operation.

Addressable RS-232C control is available via the DB-9 connector. Address selected by SW1. | Front Panel | |---| | Shutter Fuse (1) | 5 x 20mm,0. 6A, “T” time-lag fuse to protect that shutter output-one for each channel. | | N. O/N. C Switch (2) | The position of the key switch determines shutter status BEFORE a trigger signal is received by the VMM-D3-one for each channel. | | Sync.

Active LED(3) | A green LED indicator that indicates status of Solid State Synchronization output-one for each channel. | | Driver Active LED (4) | A red LED that indicates when the internal shutter driver circuit input has an active signal present- one for each channel. | | RS-232C Input (5) | DB-9 female connector provides access to the VMM-D3 RS-232C interface.

| | Address Select Switch-SW1 (6) | Selects the active RS-232C address of the unit. | | Power Indicator (7) | A red LED indicates that power is applied to the unit. |

## Rear Panel Layout All main input/output functions can be accessed at the VMM-D3 rear panel, including the 115/230VAC input. Manual switching as required.

Additionally, (2) 6-pin pluggable terminal strips allow for easy termination to input (active high) and output (active low) signals. Channel #4 output is not operational. | Rear Panel | |---| | AC Input Module (1) | AC input via IEC male receptical for AC line cord (supplied). Additional functions are described on page(s) 9-1, 15 and page 32 in the VMM-D3/D4 user manual.

| | Output Control (2) | Provides Electronic Sync. signal output from each shutter channel. Output indicates state of shutter’s Electronic Sync., if shutter is so equipped. One output for each channel. See terminal strip layout in VMM-D3/D4 User Manual page(s) 15-19. Active Low outputs. Output Terminal #5 – Active Low when all Sync. outputs go low.

| | Input Control (3) | Provides Active High control for each channel. Input TTL high – shutter open, input TTL low – shutter close. Terminal #5 – Active High, input TTL high – all shutters open, input TTL low – all shutters close. See terminal strip layout in VMM-D3/D4 User Manual page(s)15-19. | | LO/HI Select Slide Switch (4) | “HI” position allows the selection of appropriate pulse energy for 35 mm and la |
