Firmware for HAE Series B and C Mounts (4/20/2024)

This firmware upgrade is ONLY for an HAE series B and C mount. It has a built-in main board and an optional 8411 hand controller. Do not load it into a different mount. No firmware upgrade is needed if your mount works properly.

Please read the Release Notes before performing any firmware upgrades. Follow the Upgrade Instruction carefully. Loading the wrong file into the system may cause the mount inoperable!


Encoder calibration is needed for a mount with a high precision encoder (EC version) after the firmware upgrade.
