CONTROLLING
The projector can be controlled with
a. the RCU
b. the hardwired RCU (cable is not included)
c. the local keypad.
Controlling the projector with the RCU and the hardwired RCU is equal.
How to Use the RCU?
a) Point the front of the RCU to the reflective screen surface.

b) RCU used in a hardwired configuration.
Plug one end of the remote cable in the connector on the bottom of
the RCU and the second side in the connector in the front panel of
the projector labelled 'CTRL'.
c) Point the front of the RCU directly at one of the IR sensors of the
projector.
When using the wireless remote control, make sure you are within
the effective operating distance (30m (100ft) in a straight line). The
remote control unit will not function properly if strong light strikes the
sensor window or if there are obstacles between the remote control
unit and the projector IR sensor.
Projector Address
a. Software Set Up of the Projector Address.
See 'Change projector address' in chapter 'Service mode'.
Every projector requires an individual address between 0 and 255
which can be set in the Service mode. Only projectors with
addresses between 0 and 9 can be controlled with the RCU.
b. How to Control the Projector or Projectors.
The projector's address may be set to any value between 0 and 255.
When the address is set, the projector can be controlled now :
- RCU for addresses between 0 and 9.
- Computer, e.g. IBM PC (or compatible), Apple MAC, etc. for
addresses between 0 and 255.
Note : A projector will respond to a RCU set to an address of '0'
regardless of what address is set in the projector itself.
c. Using the RCU.
Before using the RCU, it is necessary to enter the projector address
into the RCU (only when that address is between 1 and 9). The
projector with the corresponding address will listen to that specific
RCU.
When address 0, 'zero address' is programmed into the RCU, every
projector, without exception will listen to the commands given by this
RCU.
