Connect your Android device to supported USB Serial, USB-to-CAN adapters, or RS485 converters to monitor, analyze, debug, and log communication in real time. Whether you're testing embedded firmware, diagnosing industrial equipment, polling Modbus registers, or monitoring automotive CAN networks, Thingsup Terminal provides a reliable and high-performance solution for field diagnostics.

Key Features
• Triple Communication Modes – Supports Serial CAN, Plain Serial UART, and Industrial Modbus RTU communication through a single, clean interface.

• Industrial Modbus RTU Polling Grid – Execute cyclic holding register scans (Function Code 03), scale raw data formats on-screen (IEEE 754 Float32, Int32, Hex, Bin, Int16), and edit values instantly via Function Code 06 (Write Single Register).

• Custom JSON Telemetry Dashboards – Import standard JSON schemas to map register addresses to named gauges, visual telemetry indicators, and custom groups, with instant Slave ID filters.

• Cyclic Auto-Send Scheduler – Automate periodic message transmission. Setup custom sequential steps, and import massive frame schedules directly from Microsoft Excel (.xlsx) worksheets.

• High-Speed Communication – Supports serial baud rates up to 2,000,000 bps (2 Mbps) for fast and reliable data capture.

• Real-Time Terminal Monitoring – Monitor incoming and outgoing data streams with a highly responsive terminal interface supporting both ASCII and Hexadecimal visualization modes.

• Background Logging – Continue logging while the app runs in the background. Wake Lock support helps prevent interruptions during long logging sessions.

• Crash & Session Recovery – Automatically restores unsaved log buffers after unexpected battery failures or app closures, protecting valuable diagnostic data.

• Smart Message Highlighting – Color-coded Sent, Received, and System messages improve readability during live monitoring.

• Export Logs – Save and share captured session data as CSV or Text files instantly utilizing the native platform share sheet.

• Flexible CAN Configuration – Configure Standard (11-bit) or Extended (29-bit) CAN frames, Data or Remote frames, DLC, and CAN baud rates to match your hardware requirements.
