2. Directive Composing Instruction:
oxFF is only bit; ox stands for hexadecimal system; FF is eective 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

5. Directive for retracting: 0xFF 0xEE 0xEE 0xEE 0xC9
6. Directive for stopping: 0xFF 0xEE 0xEE 0xEE 0xCC
7. Directive for extending: 0xFF 0xEE 0xEE 0xEE 0xE9
8. Studying address directive: 0xFF 0xXX 0xXX 0xXX 0xAA
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 is completed, but the projector lift cannot be used normally after
the address
bit has 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 two
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 dierent movement, such
as projector lift A goes down and projector lift B goes up, common directive cannot be
used and separated by address bit at this time.

12
Connect the power for projector lift A, and send out directive oxFF ox10 ox11 ox12 oxAA.
At the same time, the address of projector lift A is ox10 ox11 ox12. Entering the operating
address of projector lift A can control this projector lift.
Directive for retracting: 0xFF 0x10 0x11 0x12 0xC9
Directive for stopping: 0xFF 0x10 0x11 0x12 0xCC
Directive for extending: 0xFF 0x10 0x11 0x12 0xE9
Complete the studying in projector lift A, and then disconnect the power for projector
lift A. Please operate the projector lift B in the same way and change the address to
oxAA oxAA oxAA. Entering the operating address of projector B can control this
projector lift.
Directive for retracting: 0xFF 0xAO 0xAA 0xAA 0xC9
Directive for stopping: 0xFF 0xAO 0xAA 0xAA 0xCC
Directive for extending: 0xFF 0xAO 0xAA 0xAA 0xE9
This studying is one address bit for a long time until next address bit change to update.
After studying address bit, the common directive is still eective, so the address bit
cannot be oxEE oxEE oxEE.

4. Remote Controller Instruction
There is a matching function between the controller and projector lift, then the controller
needs to be programmed – follow these steps:
1. The projector lift is at load position. After connecting the power,
within 5 seconds please press the UP button and STOP button simultaneously
for 5 seconds, then release.
2. Press the DOWN button to check whether the programming works.
3. If the programming fails, please repeat steps 1 and 2.

PROJECTOR LIFT POSITIONING FUNCTION
There are 2 solutions to position the projector lift: upper/lower limitation and
remote localizer. NOTE: Changing these limits will void warranty.
NOTE: Do not change the factory pre-settings for any emergency, please operate
according to the following instructions if necessary.
1. Remote limit setting adjustment (Soft Limits)
a. When the projector lift installation has been completed, turn on the power to the lifter.
Confirm the lifter is operational.
b. To set the lower limit (show position), turn over the remote control and locate the limit
setting button. Press this button using a small pin or paperclip for 3 seconds and
release (red LED will light up). Then press the down button on the front of the remote.
Then the lifter is at the correct show position press stop. Turn over the remote again
and press the limit setting button, the red LED will go out and the new limit is set.
figure 16 figure 17
c. To set the upper limit (closed position), turn over the remote control and locate the
limit setting button. Press this button using a small pin or paperclip for 3 seconds and
release (red LED will light up). Then press the up button on the front of the remote.
Then the lifter is at the correct closed position press stop. Turn over the remote again
and press the limit setting button, the red LED will go out and the new limit is set.
figure 18 figure 18
NOTE: For ensuring the security of positioning function, the eective setting period
of electric positioning should be 60 seconds, after which it will return to the normal
situation. If the setting fails within 60 seconds, please repeat the following steps:
to press the setting button – LED light will turn o; press the setting button again
– LED light will turn on. With this process the resetting function will begin.
2. Upper/Lower Limitation Adjustment (Hard Limits)
Upper limitation and lower limitation are preset in the factory. The upper limitation
should be a little higher than ceiling height. Lower limitation is showed as numerical value
D in the specification table (the upper/lower limitation for sling wire should be regulated
by professional people or dealers. Improper regulation carries safety risks).
(See figures 12 & 13 on page 14)

14
figure 12 figure 13
NOTE: the following operation should only be undertaken by people fully
conversant with the lift’s operation:
a. For upper limitation adjustment, pull out the knob and adjust using the allen key
provided. A clockwise adjustment will retract the projector lift (decreasing distance
between casing and installation point) and a counter-clockwise adjustment will extend
the projector lift (increasing distance between casing and installation point).
b. For lower limitation adjustment, pull out the knob and adjust using the allen key
provided . A clockwise adjustment will extend the projector lift ( increasing distance
between casing and installation point ) and a counter-clockwise adjustment will retract
the projector lift (decreasing distance between casing and installation point).
figure 14 figure 15
MOTOR POSITIONING
Do not roll and retract the projector lift continuously
over 4 minutes at a time to avoid overheating. If the motor
overheats, wait 30 minutes for cooling. No lubrication is
needed for the motor, the drop and retract limit of the
projector lift has been prepositioned to an optimal
configuration before delivery. In order to avoid motor
damage, please consult your local dealer or a professional
technician when a new position setting is needed.
Use the M4 allen-key for adjusting the upper and lower
limitations of the projector lift, but the distance cannot be
more than value D in the specification table.
