CAT. NO. 689 REMOTE CONTROLLER
Introduction
The Cat. No. 689 Remote Controller provides the capability to control the Model
CP500 Digital Cinema Processor from multiple remote locations. The unit
features:
x Film format select
x Fader and mute functions
x A simple three-wire interface
x Projector changeover
Multiple remote controllers may be connected, each simultaneously capable of
controlling the CP500.
Installation
The Cat. No. 689 is packaged in its own housing and may be used stand alone or
installed into a console or wall by removing the top plate from the housing. Four
screws located at the corners of the top plate affix the top plate to the housing. If
the housing is used, the entry for the interface cable is designed to accept common
electrical conduit. See the fold-out manual page for wiring details.
The electrical interface to the CP500 is made over three wires:
x +24 volt power from the CP500
x An RS232-like multi-drop duplex data interface signal
x A ground return wire.
Remove the four screws attaching the top plate to the housing of the Cat. No. 689
and observe the PC board attached to the underside of the top plate. The interface
connector, marked "J1", is located on the lower left corner of the board. Connect
the unit as shown in the wiring diagram.
For compliance with FCC and European EMC requirements, it is necessary to
shield all three interface wire conductors with a braid or foil shield, which
electrically connects the chassis of the Cat. No. 689 to the chassis of the Model
CP500 and is not connected to circuit ground.
Multiple Projectors
In installations containing multiple projectors, it may be desirable to install a
remote controller at each projector. Each Cat. No. 689 can be programmed to
signal the CP500 to changeover to the projector associated with each remote
controller. The projector number is programmed by means of a switch located on
the Cat. No. 689 internal PC board. The switch is a 4 way DIP switch located in
the middle right of the board.

The remote is set at the factory with all switches ON (UP), which causes the Cat.
No. 689 not to be associated with any projector. To program the Cat 689 to be
associated with projector 1, set DIP switch 1 OFF (DOWN), and leave the other
switches ON (UP). To program the Cat. No. 689 to be associated with projector 2,
set DIP switch 2 OFF (DOWN), and leave the other switches ON (UP).
When a Cat 689 is programmed to be associated with a projector, any format
selection from that remote will cause the CP500 to switch to that projector.
NOTE: Mute and fader changes from any remote controller will not affect the projector selection.
Operation
The Cat. No. 689 is activated when the CP500 enters its Format Selection menu
"Current Format" and is disabled at all other places in the CP500 menu tree in
order to avoid unwanted activation of CP500 modes from the remote.
When the CP500 Current Format screen is active, the Cat. No. 689 is allowed to
control the CP500 in the same manner as the front panel keys on the CP500. The
eight format selection softkeys on the CP500 and their associated format-active
LEDs are repeated on the Cat 689's eight format selection switches and LEDs.
Both the CP500 fader and the Cat. No. 689 fader are simultaneously active, and the
7-segment fader displays on both devices reflect the current fader level. The mute
buttons on both devices will change the mute state of the CP500.

When a Cat 689 is programmed to be associated with a projector, any format
selection from that remote will cause the CP500 to switch to that projector,
however, mute and fader changes from the Cat 689 will not affect the projector
selection.
NOTE: The CP500 can be configured so that a particular projector is automatically associated with any
particular format. This is done using features of the CP500 Custom format screen. If your CP500 is set up
this way, it is possible that a conflict may arise between the projector associated with the format and the
projector associated with a particular Cat. No. 689 remote box. In all such cases, the projector associated
with the format will be selected, regardless of which remote box originated the command.
