4. Typical Programming Workflow

  1. Create new project – Define node count, network type.
  2. Add hardware – Populate racks with CPU, SLC, NAC, relay cards.
  3. Add field devices – SIGA detectors (smoke, heat, CO), modules (relay, monitor).
  4. Define zones – Input zones (detection), output zones (notification/appliance).
  5. Build logic – Custom Logic or Cause & Effect matrix.
  6. Configure panel attributes – Timers, silence inhibit, auto-reset, walk test.
  7. Simulate & verify – Run offline tests.
  8. Download – Connect laptop via RS-232 or USB-to-serial.
  9. Commission & test – Verify all events trigger correct outputs.

Step 4: Write Signal Logic (Rules)

Navigate to the Rules tab.

  • Create a new Group: "General Evacuation".
  • Rule 101: When ANY [Pull Station Group 1] Then ON [Horn Group A]
  • Pro tip: Use descriptive group names (e.g., West_Wing_5th_Floor). Avoid generic names like "Zone 7".

2. Software Architecture & Core Components

The SDU software suite consists of several tightly coupled modules:

| Module | Function | |--------|----------| | SDU Editor | Main programming interface: define hardware, zones, messages, C&E rules | | Panel Database Creator | Prepares a blank database for a specific panel firmware version | | Graphics Manager | Links floor plans and custom graphics to points/events (used with EST3 Vision) | | Network Manager | Defines peer-to-peer messaging between nodes, including global rules | | Debugger / Simulator | Emulates panel behavior offline to test C&E logic before downloading | | Firmware Loader | Updates bootloader, application code, and voice firmware for an AMG-1 or PMC | | Event Logger Viewer | Parses and filters panel history logs downloaded via serial or TCP/IP |

All data is stored in a Microsoft Jet (Access) database, typically with password-protected access. The database contains ~50+ interlinked tables:
Devices, Zones, Rules, Messages, Panel_Setup, Network_Links, Voice_Evac, etc.

Summary Table – Key SDU Capabilities

| Capability | Detail | |------------|--------| | Max panels | 64 | | Max devices per panel | ~20,000 | | Max rules per panel | ~5000 | | Programming model | Rule-Based (declarative) | | Networking | Token-ring, peer-to-peer | | Database format | MS Access (.mdb) | | Connection types | RS-232, modem, TCP/IP | | Simulation | Full offline emulation | | Reporting | Event logs, device inventory, C&E cross-reference |

Title: The Ghost in the Optic

The rain in Sector 4 didn't fall; it hovered, a thick, suffocating mist that clung to the neon signage and the weary synth-leather jackets of the locals.

Elias Vance sat in the back of a dumpling shop, the steam from his bowl obscuring the device on the table. It was a matte-black brick, ruggedized against shock and water, with a heavy rubberized grip. To the untrained eye, it looked like an industrial scanner or a vintage camcorder. But Elias knew what it was. He knew the weight of it.

It was the EST3 SDU.

Most people thought the EST3 was just a high-end "Spatial Data Unit"—a tool used by architects to map collapsing buildings or by police to reconstruct crime scenes. But the version sitting on Elias’s table wasn’t retail. It was "Software Defined," and it was running a patch that wasn't supposed to exist. est3 sdu software

"Three thousand," a voice rasped.

Elias didn't look up. He fished a dumpling out of the broth with trembling fingers. "Sit down, Kael."

Kael slid into the opposite booth. He was young, twitchy, his eyes darting to the device. "You said you had the 'Phantom' firmware. Is it loaded?"

Elias wiped his mouth. "The EST3 is a unique platform, Kael. You know why? Because the hardware is dumb. It’s a vessel. The magic is in the software. Right now, this thing is running the standard industrial survey package. It beeps, it scans, it measures distance."

"Load the drive," Kael hissed, sliding a micro-data chip across the sticky table.

Elias picked up the chip. He turned it over in the light. "This is military-grade ghost-hunting tech. If the Grid Authority catches you with an SDU running this algorithm, they don't arrest you. They delete you."

"I paid the fee," Kael said, sweating. "Load it."

Elias sighed. He slotted the chip into the side of the EST3. The device hummed, a low vibration he felt in his bones. The screen flickered from a friendly amber to a harsh, clinical crimson.

[INITIALIZING SDU PROTOCOL: PHANTOM v.9.0]

The EST3’s lens, usually a passive glass circle, dilated mechanically. A fan whirred inside the casing.

"The SDU software reconfigures the hardware," Elias narrated, his voice low. "It stops capturing light. It starts capturing residue. Intent. Echoes."

He pointed the device at the empty seat next to Kael.

The screen buzzed with static. Lines of code scrolled rapidly, too fast for human eyes, building a wireframe in real-time. The EST3 chirped—a sharp, aggressive sound, unlike the polite beep of the survey tool.

Kael went pale. He was staring at the screen. "What is that? There’s nobody there."

"There is," Elias said, watching the readout. "Three hours ago. A woman. She sat where you’re sitting. She was scared."

The EST3’s software wasn't just recording; it was interpolating. It took the ambient heat displacement, the microscopic depressions in the cushion, the lingering pheromones, and it reconstructed a ghost. A wireframe woman appeared on the screen, mouthing silent words.

Kael reached out, mesmerized. "Can it hear her?"

"The software can reconstruct vocal cord vibrations from the glass pane behind you," Elias said. "But Kael... you told me you wanted to find your missing partner. You said she vanished."

Kael froze. His hand hovered over the device.

The wireframe woman on the screen turned her head. She was looking directly at the camera. She was looking at Kael. The EST3 SDU (System Definition Utility) is the

[TARGET IDENTIFIED: TRAJECTORY ANALYSIS ACTIVE]

The EST3 began to beep faster. Louder.

"She didn't vanish," Elias said softly, his hand drifting to the heavy blaster under his coat. "Did she?"

Kael’s face twisted. "She was going to leave me. She was going to the authorities."

The EST3 chirped one final time. A red box highlighted a spot on the floor beneath their table. [ORGANIC RESIDUE DETECTED. TEMP: 2 HOURS.]

"You used the wrong tool for the job, Kael," Elias said, clicking the safety off his weapon. "You wanted to buy the SDU software to see if there were any ghosts haunting you. You didn't realize the EST3 doesn't just find ghosts."

Elias leveled the gun.

"It records everything."

The EST3 sat between them, its crimson lens staring blindly, the software patiently processing the data of a murder that was about to be avenged.
