Studying Directive and Operation

After connecting power, studying status will operate within the first 10 seconds. The studying

directive is oxFF oxXX oxXX oxXX oxAA. The screen can be used normally after study completed,

but the projector lift can not be used normally after the address bit changed, so that one port can

be used to control many projector lifts.

Example:

There are projector lift A and B with RS-485 port, if need to control these rwo projector lifts

synchronously that the directive oxFF oxEE oxEE oxEE oxDD will be sent out from the port. If

need to control these two projector lifts in different movement, such as projector lift A goes

down and projector lift B goes up, common directive can not be used and separated by address

bit at this time.
