Firmware for HAE Series Mount (7/23/2023)

This firmware upgrade is NOT for the HAE29/43/69B and C version mount, which can be operated without an 8411 handset.

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.
