Why the SMC 4000 and 5000?

Full-Matrix Design

The continuous, full-matrix design allows the display of messages using text, graphic symbols, or both. Graphic symbols are displayed at a standard 50-inch height and text messages are displayed using either 20″ or 28″ tall characters.

LED Lamp Pixel Design

The SMC 4000/5000 uses 5 high-intensity, solid-state LEDs per 2-inch pixel. This creates a more uniform light output in each pixel, resulting in increased message definition and distance legibility.

Standard NTCIP-Compliant Controller

A user-friendly, NTCIP-compliant, dedicated computer reduces the number of keys required to program the SMC 4000/5000.

Sign Flexibility

The Mast-Mini is designed for use in areas where space is limited and provides variable character fonts with both 12″ and 18″ character heights.

Standard NTCIP-Compliant Controller Full Matrix Display

The Mast-Mini provides 250 text, 60 graphic and 20 arrow board display messages preprogrammed and stored in the controller. Additionally, 100 user-created messages can be programmed and stored.

Industrial-Grade Structural Steel Trailer

The Mast-Mini uses a durable trailer system designed to provide years of dependable service. The trailer’s high-quality powder-coat finish, 2″x 3″ 11-gauge steel frame and a 2,000-pound axle enhance the overall durability of the unit and has 4 leveling jacks with slide out extensions provide stability when deployed.

Modular Electronic Componentry

The entire system was developed with the operator/end user in mind. Electronic components are easily replaced, reducing downtime and maintenance costs. This modularity also improves system diagnostics.
