Right panel, Host/Config port — For MLC configuration and
control, connect to the 3-pin captive screw.
This port has the following RS-232 protocol:
• 38400 baud
• 1 stop bit
• no parity
• 8 data bits
• no flow control
b
Display RS-232 /IR port — This port is configurable for
bidirectional RS-232 or infrared signal output control.
From this port, commands sent from a driver or user-defined
command strings (entered via the Global Configurator) can be
sent to the display device.
For bidirectional RS-232 communication, the transmit, ground,
and receive pins must be wired at both the controller and the
projector connectors, as shown on the following page.

SCP Comm port — The SCP 104 replicates the MLC’s front
panel controls. You can connect up to two Extron SCP 104
control pads to this port to allow remote control of the MLC 104
controller.
SCPs can be daisy chained. Extron recommends the
Comm-Link (CTL and CTLP) cable for these connections.
