Topcon MC-R3 (3D-MC2) fh915+ Antenna GPS Machine Control

The Topcon MC-R3 is the receiver box at the core of Topcon 3D-MC and 3D-MC2 grade control systems, combining the GNSS receiver, correction radio and machine controller in one powder-coated cast-aluminum housing with a built-in status panel and function keys. Tracking dual-frequency GPS + GLONASS RTK, it feeds position to the control software and drives the valve outputs that let dozers, graders, excavators and scrapers hold grade automatically; in 3D-MC2 installations it works alongside the GX-60 control box and an inertial sensor for faster blade response.

This listing is the FH915+ variant, P/N 9907-0001, carrying Topcon’s internal 900 MHz radio for RTK corrections, and it ships with the FH915+ antenna called out in the title. Power input is 10-30 VDC, with I/O across four RS-232 ports, RS-485, dual CAN, dual Ethernet and I2C on two Deutsch DRC23-40P connectors — the exact hardware shown in the photographs.
