2. Bracket is a part of projector lift，and combine hanger、threded rod（M10）、nut（M10） to the following
mechanism. Cut the length of threded rod (M10) for H-C+60mm, H is the distance concreted-ceiling and
ceiling surface, which measured in last step. C is the height of frame in specification table.
(Example: H is 1000mm, height of bracket C is 600mm, the length of H-C+60 is 460mm), figure 3.

3. Ensure the security distance M、N according to the figure 4 and the model of table. Install the brackets to
the roof via the screws, figure 5.

Grandview Projector Lift RS485 Setting Address
1、RS-485, RS-232 input
A continuous data sends two times，each time interval of 200ms
3 bytes of studying address directive are custom setting address directive
Central Control Format Agreement
1)Communication Agreement Setting
Data Bits: 8 bits
Start Bits: 1 bit
Stop Bits: 1 bit
Baud Ratio: 2400
Common directives are in chip of projector lift and can not be changed
2) Directive for retracting：
3) Directive for stopping：
4) Directive for extending：
5) Studying address directive:
2. Directive Composing Instruction:
oxFF is only bit; ox stands for hexadecimal system; FF is effective bit; a directive is composed by 5 bits.
Studying directive oxFF oxXX oxXX oxXX oxAA
oxFF and oxAA can not be changed, but oxXX oxXX oxXX can be changed to any 16 hex data, which stand for
address bit
The changed working directive
1) Directive for retracting:
2) Directive for stopping:
3) Directive for extending:
4) Studying address directive:
Example: The studying directive is oxFF ox10 ox11 ox12 oxAA which can be changed to:
5) Directive for retracting:
6) Directive for stopping:
7) Directive for extending:
8) Studying address directive:
3. 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.
