Overview
CHINOWING V21 is an RC data link designed for long-range video and telemetry. It integrates image transmission, network protocol compatibility, and transparent data transmission across 800MHz, 1.4GHz, and 2.4GHz bands. The system supports transparent transmission for seamless image/data transfer, dual S-BUS I/O for remote control integration, and a TTL/RS232 serial interface for flexible device connectivity. LAN video I/O enables connection to IPC devices or a PC. Typical latency is 20ms from Tx to Rx.
