2.4.2 The digital video input accepts SDI Video as defined by
ANSI/SMPTE 259M-1997 digital format.
2.4.3 SP-LCD6 is an external switch utilized for monitor set-up. The
switch, which must be ordered separately, provides configuration
control via DAAI’s proprietary RS-485 digital data bus
communication or may be configured directly to the J2 connector.
Refer to Section 3.8, Configuration Overview, for monitor set up.
The SP-LCD6 may be removed and stored after the monitor is set
up or can be mounted near the monitor for frequent use. Connector
J2 provides to the switch panel +28 VDC power and ground input,
serial data bus control, and unit ID strapping pins to allow
programming of multiple units.
2.4.4 Device addressing is accomplished via three (3) ID pins, which
allow for a total of eight (8) monitors to be independently addressed
on the data bus.
2.4.5 The monitor casing is specially designed for EMI and noise filtering,
guaranteeing a reduction in interference to ensure a high-quality
display.
2.4.6 A shallow mounting depth makes this monitor ideal for bulkhead
use. Convenient mounting holes are strategically located on the left
and right sides. An optional front cover bezel (see Section 1.3) may
be purchased for added mounting capabilities. Other plating options
are available and allow matching to other cabin décor of the
aircraft.
