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,

projector numbers, see 3.7, Adjusting and Checking System Parameters.
