6.7. EXT CTRL Port Wiring Diagram
6.8. Extending Control Wiring
6.8.1. Wall Switch
1. Run a Cat5e/6 cable from the projection screen EXT CTRL port to the switch location. Install the cable into the
wall at the switch location, and cut a 1" hole at the desired switch height. Pull about 6" of cable out of the hole
for attachment to the wall switch.
2. Remove the knockout from the switch back-box and mount it over the cable with the RJ12 port opening pointing
down. Use the supplied screws and anchors to secure it to the wall.
3. Cut the RJ12 control cable. Leave about 12" of cable attached to the connector. Splice four of the Cat5e/6
conductors to the appropriate wires as shown above at the projection screen. Then, plug the RJ12 into the EXT
CTRL port. Insulate the ends of the unused RJ12 conductors 1 and 2 to prevent short circuits.
4. Strip the insulation from each of the four conductors used in the Cat5e/6 cable about ¼". Locate the press-fit
connector on the switch assembly and terminate the conductors as shown above. Make sure to match the pin-
out correctly between the screen and the wall switch.
5. Mount the wall switch to the back-box so that the up and down buttons face the right directions.
6.8.2. Contact Closure or RS232 Control
1. Run a Cat5e/6 cable from the control system processor location to the projection screen.
2. Cut the RJ12 cable and leave about 12" of cable attached to the connector.
3. Terminate conductors in the Cat5e/6 to the desired pins of the RJ12 connector as shown in the diagram above.
Insulate the ends of the unused RJ12 conductors to prevent short circuits.
4. Terminate the same conductors to the appropriate wires on the RS232 port or contact/relay connection of the
control system processor.
