To superimpose two images to one screen, the same image is required to input
to Main and Sub projectors. There are some options to input image to the
projectors. This chapter shows you such option for connection of cables. Read
this chapter to nd one that matches to your demand.
4.1 Connecting RS-232C cable
If you use Intellectual Stack, connect RS-232C port on Main and Sub projectors
with an RS-232C cross cable. (

) If you use Simple stack, it is not required.
4. Connecting cables
NOTE • If you use Simple Stack without an RS-232C connection, Main and
Sub projectors mentioned below do not exist. So, be aware that Main read as
a projector and Sub does as the other in this chapter.
• For detail of input port, specs, connections and so on, refer to Connecting
with your devices (←
Operating Guide) and Connection to the ports (←
Operating Guide - Technical)
NOTE • If the cable that connects two projectors working in Intellectual Stack
is disconnected, the projectors exit from Intellectual Stack and start to work
individually. Even if the cable is just connected again, Intellectual Stack will not
restart. Go through the following procedure to restart Intellectual Stack.
(1) Leave the both projectors unattended for 10 seconds or more after the cable
is disconnected, to let projectors recognize that.
(2) Turn off the both projectors, and allow them to cool sufciently.
(3) Reconnect the two projectors with the RS-232C cable, and turn them on
again. Then Intellectual Stack will restart.
