How does the wireless connection perform in areas with radio interference?

The LS-B110W uses frequency-hopping spread spectrum technology that automatically selects the clearest channel from multiple frequencies. This ensures reliable communication even on busy jobsites with multiple radio systems, cell towers, or other potential interference sources. The system continuously monitors signal quality and alerts the operator if connection strength drops below optimal levels.

Can I use this receiver with my existing rotary laser from another manufacturer?

The LS-B110W is designed to work with most standard rotating lasers that emit in the red or infrared spectrum, including many brands beyond Topcon. However, for optimal performance and to access all features (particularly advanced slope functions), we recommend pairing it with Topcon RL-series lasers.

What happens if the wireless signal is lost during operation?

The system includes multiple fail-safe features. If wireless communication is interrupted, the display immediately alerts the operator with both visual and audible warnings, and the last known grade reading is held on screen with a clear signal lost indicator. The receiver continues tracking the laser, so once radio communication is restored, operation resumes without recalibration.

How long does it take to set up the wireless system compared to a traditional wired receiver?

Most operators report setup time reductions of 50-70% compared to wired systems. After the initial one-time pairing, subsequent setups involve simply mounting the receiver on your mast, placing the display in the cabin, and powering both units on—typically completed in under 5 minutes.

Overview

The Topcon LS-B110W Laser Machine Display Receiver (Model 312670121) represents a breakthrough in construction grade control technology, eliminating the frustration of tangled cables and complex wiring systems that have plagued equipment operators for decades. This wireless-capable laser receiver delivers precision grade and tilt data directly to your grader, dozer, or paver cabin through a secure radio link, transforming how you approach site preparation and finishing work.

Designed for contractors who demand both accuracy and efficiency, the LS-B110W system consists of a rugged exterior receiver unit that mounts directly on your machine's blade or screed, paired with a crystal-clear remote display positioned within easy view of your operator station. The wireless communication between these components means no more umbilical cables draped across your equipment, no more damaged wires from blade movements, and no more time wasted troubleshooting connection issues in the field.

This system excels in both single-slope and dual-slope applications, providing real-time elevation feedback that keeps your operators on-grade with millimeter precision. Whether you're working on highway paving projects, building pads, parking lots, or agricultural land leveling, the LS-B110W delivers the reliable performance Topcon is known for, now with the added convenience of wireless freedom. The intuitive interface reduces operator learning curves, while the robust construction ensures this receiver will perform season after season in the harshest jobsite conditions.

Job Applications

Highway and Road Paving: Achieve smooth, accurate road surfaces by maintaining precise elevation control during asphalt placement. The wireless system allows paver operators to adjust grade in real-time without cable restrictions, reducing the need for costly rework and ensuring specifications are met on the first pass.
Building Pad Preparation: Establish level foundations for commercial and residential construction projects with confidence. The dual-slope capability enables quick transitions between different grade requirements across the site, while the wireless display keeps operators informed without leaving the cabin to check external gauges.
Parking Lot and Site Development: Create proper drainage slopes and smooth surfaces for parking facilities and commercial developments. The system's precision prevents ponding issues and ensures ADA compliance, while the cable-free design speeds up setup when moving between different areas of large sites.
Agricultural Land Leveling: Optimize irrigation efficiency and crop yield by achieving precise field elevations. Farmers and land improvement contractors benefit from the long battery life during extended grading sessions, and the rugged construction withstands the demanding agricultural environment.
Trenching and Underground Utility Installation: Maintain consistent slopes for gravity-fed drainage, sewer, and storm water systems. The wireless receiver eliminates the risk of cable damage when working around trenches and excavations, improving both safety and productivity.
Sports Field and Golf Course Construction: Deliver the precise contouring required for athletic facilities and recreational landscapes. The millimeter-level accuracy ensures proper drainage and playability, while the intuitive display helps operators achieve complex grade transitions smoothly.

Contact our technical team to verify compatibility with your specific laser model.
What happens if the wireless signal is lost during operation?: The system includes multiple fail-safe features. If wireless communication is interrupted, the display immediately alerts the operator with both visual and audible warnings, and the last known grade reading is held on screen with a clear "signal lost" indicator. The receiver continues tracking the laser, so once radio communication is restored (typically within seconds), operation resumes without recalibration.
How long does it take to set up the wireless system compared to a traditional wired receiver?: Most operators report setup time reductions of 50-70% compared to wired systems. After the initial one-time pairing (which takes about 2 minutes), subsequent setups involve simply mounting the receiver on your mast, placing the display in the cabin, and powering both units on—typically completed in under 5 minutes. Eliminating cable routing through machine articulation points and protecting wires from blade movement saves significant time on every job.
