MonitorLink™
MonitorLink is a new digital interface introduced in
Mitsubishi's 2003-2004 model line, including the
V23 chassis.
MonitorLink provides a proprietary connection for
Mitsubishi's HD-5000, Monitor/Receiver, allowing
Mitsubishi's upgradeability promise to be fulfilled
using a digital, rather than analog, interface.
While MonitorLink is a proprietary connection, it
uses industry standard technologies that may pro-
vide even more versatility.
• RS-232C - Provides device communication
and control.
• Audio - Standard analog stereo connections.
• DVI - (Digital Visual Interface) Provides a
digital video connection.
RS-232C… The RS-232C connection interfaces
communications and control between the receiver/
controller and display. Commands such as Power
On, Input, Mute, etc., make the system operate as
one via the customer's remote control.
Audio… Analog Left and Right Audio connectors
are provided for the set's internal audio/speaker sys-
tem. The V23 chassis has digital audio outputs and
IEEE1394 for more advanced connections with an
external A/V receiver.
DVI… Technicians experienced with computer
monitors may already be familiar with DVI and its
features. However, because it is new to home the-
ater, it will be covered here further.
Digital Visual Interface (DVI)
DVI was originally designed by the Digital Display
Working Group (DDWG) to provide a universally
accepted digital connection between a PC and a dis-
play device.
At first glance, another digital interface would seem
unnecessary with the presence of IEEE1394,
Firewire. However, differences between IEEE1394
and DVI make them each suitable for different ap-
plications. A comparison of the two interfaces, as
applied to home theater, is provided in Table 4.
Simply stated, 1394's bi-directional, compressed
data, and AV control capabilities make it suited for
recording and networking between various devices.
DVI's high speed, full bandwidth capabilities make
it most suitable to connect a display device.
