## Physical Layout

- Sketch of the Control Room layout

- Describe the lighting
*Three light sources—see photos*
- Natural (but mostly blocked now)
- Wall lights

## The Consoles

- Elliott McCrory

## Console Module Design (side view)

- Back

- Front

## Console Module Design (support)

- Knee / toe room is 24 inches – same as modular office furniture

- _Bolt-down Plate:_
- Provides template for positioning console on floor.
- Bolted to Concrete floor to stabilize console
- Has large openings to allow drilling holes in raised floor for cabling and air flow (that misses raised floor support structure).
- Console is bolted down to plate after plate is installed

## Console Module Design (CPU)

- 9 in x 18 in x 18 inch space provided for CPU

- Shelf pieces support CPU so that back panel can slide under it and so that air flow is not obstructed

## Console Module Design (Table Top)

- Removable Formica bench (Corian was considered but felt cold and was expensive)
- Bull nose 30 inches from back wall; connects adjacent consoles seamlessly

- Bench support arms – 4 per console

## Console Module Design (Access)

**Console Module Design ****(Access)**

-  Removable front panel allows quick access to CPU
-  Panels held in place by finger latches - no screws

- Structure is almost entirely open for cabling, PA mixers, air flow, etc. (Vertical struts divide internal area into 3 bays)

- CPU

- Removable, “clam shaped” back panel allows quick access to cabling area.
- Panels remove by just pulling them out, no screws

## Console Module Design (Air Flow)

- Holes hidden from view but allow air to exhaust

## Console Design (Monitors, Keyboard)

- Black brush assemblies used to allow monitor, keyboard, mouse and other cables to enter console interior and be hidden.

- _Monitor Mounting Arms_
- Commercially available arms that fold so that monitor is held a small distance away from wall.
- Extend nearly a foot and allow rotation in two dimensions

## Console Module Design (Utilities)

- _Utilities:_
- Network Ethernet Connections
- USB Port
- Phone jacks
- Microphone jacks
- AC Power outlets

## Console Module Design (optional section)

- _Top Hat_
- Sloped to prevent sitting coffee cups etc on it
- Removable so can be used on structure with only on row of monitors. (Height is 1 in taller than top of monitor)

- _Upper Section:_
- Removable to allow each console to be one monitor or two monitor rows high

## Console Module Design (front view)

## Half-Height Console Module (front view)

- Allows view over top to the Safety System Racks

## Console Module (multiple PC’s)

- PC Choices:
- Windows
- Linux
- Network Choices:
- Control System
- Test Equipment
- Office computing

- One Operator Station, 2 PC’s
