To superimpose two images onto one screen, the same image must be input to
the Main and Sub projectors. There are various methods to input the image to the
projectors. This chapter describes different ways to connect the cables. Read this
chapter to nd a method that meets your needs.
4.1 Connecting an RS-232 cable
If you are using Intelligent Stack, connect an RS-232 null modem cable between
the
CONTROL
ports on the Main and Sub projectors. (

) This connection is not
required if you are using Simple Stack.
4. Connecting cables
NOTE • If Simple Stack without an RS-232 connection is used, the Main and
Sub projectors described below do not exist. Main in this chapter refers to one
projector and Sub to the other projector.

NOTE • If the RS-232 cable becomes disconnected between the two projectors
operating in Intelligent Stack mode, the projectors will exit from Intelligent Stack
and start to operate individually. Intelligent Stack will not restart even if the cable
is reconnected. Follow the procedures below to restart Intelligent Stack:
(1) After the cable has become disconnected, do not operate the projectors
for more than 10 seconds to allow the projectors to recognize the cable
disconnection.
(2) Turn off both projectors and allow them to cool sufciently.
(3) Reconnect the two projectors with the RS-232 cable and turn them on again.
Intelligent Stack will restart.
