Product Snapshot
MultiWave is a purpose-built field diagnostics device that tests RJ45, RJ11, and BNC cables through a wireless two-node architecture. It was designed for practical cable verification in environments where both cable ends are physically separated.
Engineering Goal
Traditional cable testers are often tethered and connector-specific. MultiWave aims to provide:
- multi-connector support in one platform
- untethered endpoint validation over RF
- mode-driven diagnostics for both quick checks and deep fault isolation
- portable operation with dedicated power management
Two-Node System Architecture
The platform is split across two physical units:
- receiver/controller node:
- drives test sequencing
- energizes and scans pin patterns
- renders operator feedback on OLED and LEDs
- transmitter/remote node:
- senses remote conductor states
- returns readings to controller in near real time
- RF link:
- nRF24L01+PA+LNA modules for bidirectional communication
This architecture allows end-to-end testing without dragging both cable ends to a single enclosure.
Diagnostic Mode Design
- Continuity mode:
- validates line-by-line conductor integrity
- quickly identifies opens and missing paths
- Wiring mode:
- checks expected pin map standards
- catches swaps and crossover mistakes
- Short mode:
- detects unintended coupling between lines
- useful for damaged crimps/connectors
- Manual mode:
- pin stepping for targeted technician debugging
- enables deterministic fault tracing
Hardware and Interface Stack
- Arduino Mega 2560 + Mega 2560 Pro
- 1.3” I2C OLED for status/UI
- LED arrays for immediate visual pin feedback
- RJ45, RJ11, and BNC connector interfaces
- battery + boost/power subsystem for portability
Firmware Characteristics
MultiWave firmware coordinates pin drive/read cycles, RF message exchange, and display updates under a deterministic test loop. Mode separation keeps operator workflows clear and reduces ambiguity during field diagnostics.
Practical Field Advantages
- supports mixed connector environments
- avoids single-box physical limitations
- gives both quick pass/fail and detailed analysis paths
- designed for mobile usage rather than bench-only operation
Why This Build Is Significant
MultiWave is a full-stack hardware project in the real sense: embedded firmware, RF transport design, electrical interface mapping, device UX, and power/enclosure engineering all had to align for reliable on-site operation.
