Designation
J6 unmarked
The J6 USB mini-B female connector allows for factory and in-field programming of the RC4000's
operational software via a standard USB cable. At power up, the RC4000's bootloader software checks
the presence of a powered USB cable. If a USB cable is detected, the bootloader switches into
downloading mode but if no USB is detected the bootloader will jump to the currently stored program for
normal operation.
The update procedure is as follows:
1) Power off ACU. Connect USB cable between ACU and PC.
2) Power on ACU, wait for USB drive to be created on PC.
3) Drag hex file (attached) to USB drive. Wait for file to copy over.
4) Power off ACU. Disconnect USB cable between ACU and PC.
5) Power on ACU. New software can be identified by version and build number.
