MLC 60 Series Rear Panels
Host/Config port
— This bidirectional RS-232 serial port can be used for
configuration and firmware updates in the same way as the USB port (see
on page 10). The baud rate is 9600 bps. This port can be used
as a backup for the USB Configuration port (although you cannot power a device
through it).
Digital Input port
(RS models only)
— This port enables the MLC to monitor
devices such as push buttons, switches, motion sensors, and moisture sensors and
provides an additional way to trigger functions on the MLC. Connect a switch or a
sensor to this 2-pole captive screw connector to initiate commands via the MLC to
the display device, switcher, or other room devices such as lights or a motorized
screen.
Relay ports (RS models only)
— These relays allow control of room devices such
as motorized screens, lights, and projector lifts. They are normally open relays and are
rated at 24 V, 1 A. Low-power devices can be connected directly to the relay ports;
devices requiring more than 24 V can be connected through a third-party low-voltage
controller (LVC).
