General Information
A new HFA II-i Motor Driver board (P/N 63710) has been released.
The current Motor Driver board (P/N 61190) has logic level incompatibilities between the 3.3 volt devices
and microprocessor, which runs on 5.0 volts. The logic levels rarely affected the operation of the
instrument, but in some cases the unit will not boot up to the main menu.
The new Motor Driver board (P/N 63710) can be used as a replacement for the previous Motor Driver
boards used in the HFA II-i.
