Connecting cables, Connecting an RS-232 cable

4. Connecting cables

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 find a method that meets your needs.

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.

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. (8) This connection is not required if you are using Simple Stack.

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 sufficiently.

(3)Reconnect the two projectors with the RS-232 cable and turn them on again. Intelligent Stack will restart.
