The Futaba CIU_2 provides a direct USB connection between a Windows PC and compatible Futaba speed controllers and gyros for configuration and data management. It is intended as an RC-scale programming accessory to read, adjust, and store setup parameters for MC401CR, MC601 and MC850C electronic speed controllers and the GY520 gyro.
Connection is straightforward: the CIU_2 includes a USB connector and a 19.7in extension cable to reach equipment in typical 1/10–1/8 scale car setups. The interface draws typical USB bus power and communicates with Futaba's configuration tools on supported Windows versions stated below.
Key functions focus on parameter access and tuning support rather than runtime control. Available controls include variable frequency range selection, low battery cut settings, current limiter selection, brake duty limits and neutral brake adjustments. A data logging function allows reading and erasing stored logs for troubleshooting or recording setup changes.
System requirements: PC with Windows Vista, Windows XP, or Windows 2000 and an available USB port. The CIU_2 relies on host software compatibility so confirm your configuration tool supports the listed OS before use.
Use the CIU_2 when you need a simple USB link for setting and logging parameters on supported Futaba ESCs and the GY520 gyro, keeping configuration work on the bench or at the trackside PC.
