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 the ways of connecting the cables. Read this
chapter to nd a method that meets your needs.
4.1 Connecting an RS-232C cable
If you are using Intellectual Stack, connect an RS-232C cross cable between the
RS-232C 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-232C connection is used, the Main
and Sub projectors described below do not exist. Main in this chapter is read
as one projector and Sub as the other projector.
• For details on the specications of the input ports, refer to Connecting with
your devices (Operating Guide → Setting up) and Connection to the ports.
(Operating Guide - Technical)
NOTE • If the RS-232C cable connecting the two projectors operating in
Intellectual Stack is disconnected, the projectors will exit from Intellectual Stack
and start to operate individually. Intellectual Stack will not restart even if the
cable is reconnected. Follow the procedures below to restart Intellectual Stack.
(1) Do not operate the projectors for more than 10 seconds after disconnecting
the cable to allow the projectors to recognize the disconnection of the cable.
(2) Turn off both projectors and allow them to cool sufciently.
(3) Reconnect the two projectors with the RS-232C cable and turn them on
again. Intellectual Stack will restart.
