required.
c. Connect the other end of the projector control cable to the MLC
Display/Source Control RS‑232 port. Wiring depends on the projector. See
the diagrams below and on page 8, and the pin assignments in the projector
user manual. Also see the display driver setup document available from
the download page of the Extron Web site.
