INSTALLATION & SETUP
DLV 1280 User's Manual
2-19
To control multiple projectors with a computer/controller, chain the projectors
together by connecting the "
RS-232 OUT
" connector of the first projector (already
connected to the computer/controller) to the "
RS-232 IN
" connector of the next
projector in the chain. See Figure 2-26.
Figure 2-26. Adding Another Projector
Continue connecting projectors in this way to the last projector in the chain, so
that only the last projector has an empty "
RS-232 OUT
" connector. See Figure 2-27.
Communication parameters such as baud rate must be set to match your
controlling device—refer to the documentation for the controlling device. See
3.7, Adjusting and Checking System Parameters if you need help changing the
projector baud rate from its default of 38400.

Notes: 1) To avoid damage, connect only properly wired RS-232 serial
communication cables to the DLV 1280 RS-232 connectors. 2) It is
recommended that each communication cable be no more than 25 feet in length.
Each projector can be assigned a unique 3-digit projector number (for example,
001). These numbers are particularly useful when you are working with multiple
linked projectors, enabling you to direct commands to a certain projector rather
than broadcast to all projectors. For complete information on how to assign
projector numbers, see 3.7, Adjusting and Checking System Parameters.
