RD-300 3-Inch LED Display: Optical Sun-Visor Hood, Weatherproof Cabinet & Driver Visibility

High-Visibility Outdoor LED Architecture
RD-300 3-Inch LED Display Cabinet Metallurgy & Powder Coating

Extruded Aluminum Housing with Matte Black Finish. Engineered for outdoor mounting in direct Iraqi sunlight.

  • Heavy galvanized cold-rolled steel cabinet with electrostatic outdoor polyester powder coating.
  • Integrated top sun visor hood shades the optical window from direct midday desert solar glare.
  • Heavy-duty adjustable steel swivel brackets allow horizontal and vertical aiming towards truck driver eye-level.
Ingress Protection & Optical Window (IP65 Rated Weather-Sealed Enclosure)

IP65 sealed weatherproof cabinet designed for severe sandstorms and driving rain.

  • High-impact tinted acrylic/polycarbonate faceplate with anti-reflective optical treatment.
  • Gasket-sealed perimeter prevents airborne dust, desert sand, and water jets from entering the cabinet.
  • Passive labyrinth thermal cooling vents prevent internal heat buildup without compromising dust sealing.

High-Luminance LED Digits & Distance Visibility

Compact footprint with brilliant visibility; compatible with SCA1, KRONOS, BM1000, and all major indicator brands.

High Daylight Contrast Visible up to 40 meters distance provides clear readability through dirty truck windshields.
Automatic Day/Night Dimming Integrated ambient optical sensor automatically dims LED intensity at night to prevent blinding approaching truck drivers.
Status Annunciator Matrix Clear annunciator icons indicate Gross, Net, Tare, Stable reading, and metric kg units to the driver.

RD-300 3-Inch LED Display: Serial Communications, Auto-Baud Detection & Current Loop Interfacing

Hardware Interface Map
Serial Input Terminals & Power Supply Wiring Map
RS-232 (RXD/GND) Direct serial link from scale indicator cabin (Baud: 1200–19200 bps)
RS-485 (A+/B-) 2-Wire balanced differential line for long distances: RS-232, RS-485 Serial Interface
20mA CURRENT LOOP Active or passive current loop interface immune to plant electrical noise
MAINS POWER Power supply: 110V - 240V AC 50/60Hz (Mains Surge Suppressed)
LOOP-OUT Standard Multi-Drop Baud Rates allows daisy-chaining multiple displays
Protocol Compatibility & Auto-Sensing Intelligence
  • Auto-Baud Protocol Sensing: Microcontroller automatically detects and synchronizes with indicator baud rate and data string formats.
  • Universal Indicator Support: Works seamlessly with SCA, KRONOS, Toledo, Rinstrum, Dini Argeo, and Avery indicator data protocols.
  • Zero Display Latency: Zero Drift mirrors indicator instantaneously.
  • Surge Guard: Shock-Resistant LED Array protects communications boards.
Outdoor Cabling & Surge Protection Advisory: Always route outdoor RS-485 and current loop communication cables for RD-300 3-Inch LED Display through grounded metal or rigid PVC conduit. Use Waterproof Connector Port with Wall/Pole Mount Bracket to protect against lightning-induced transients.

RD-300 3-Inch LED Display: Regional Field Performance Across Iraq & Solar Radiation

COSQC Legal Verification
Southern Iraq (Basra Customs & Refinery Gates)

High ambient humidity and industrial emissions require UV-stabilized polycarbonate faceplates to prevent discoloration and yellowing over years of service.

Central Iraq (Baghdad & Western Corridors)

Extreme midday sun (>100,000 lux) and temperatures over +50°C. High-brightness LEDs and sun-visor ensure driver readability without cabin disputes.

Kurdistan Region (Border Checkpoints & Mountain Roads)

Freezing winter temperatures down to -20°C. Solid-state LED construction eliminates cold-weather start-up lag and digit freezing.

Iraqi Legal Metrology Auxiliary Display Standards

Functions as a legal auxiliary repeater display compliant with COSQC and OIML R76 regulations, providing transparent weight verification directly to truck drivers.

OIML R76 Compliant Auxiliary Repeater Automatic Night-Dimming Anti-Glare UV-Resistant Desert Enclosure
