Operating Multiple Projector with Remote Control
You can operate as many as 64 projectors with the same remote control in wireless operation.
To do so:
1. Select [Settings Menu]®[Projector ID] under the main menu and assign an ID number to each projector.
2. Specify the remote ID number to the projector to be used. To do, press and hold the CTL and press Adr button to enter the ID
number.
You can operate the projector assigned the same ID number as the remote address.
Projector ID= 01Projector ID= 02 Projector ID= 03
Remote Address = 03
You can daisy-chain as many as 64 projectors and operate them separately with the same remote control in wired operation.
To do so:
Use the remote control cable supplied to connect the Remote Control Output of one projector to the Remote Control Input of the next
until all the projectors are connected.

To calculate:
EX C6-EX C0  can be presented in binary; Lo=1 and Hi=0
Convert a decimal number (channel number) to the binary number.
Example: Channel number14 (master 1 and slave 4)=23 + 22+ 21. Set C3, C2 and C1 to Lo.
In other words 14=26 x 0 + 25 x 0 + 24 x 0 + 23 x 1 + 22 x 1 + 21 x 1 + 20 x 0
Therefore you will get C6=Hi, C5=Hi, C4=Hi, C3=Lo, C2=Lo, C1=Lo, C0=Hi
