M-LYNX-503 / Operating Instructions

1. OVERVIEW

The M-LYNX-503 provides three independent wide-screen displays in only 2RU rack height
and very slim 1.75” (44.5mm) depth. Each display has inputs for 3GSDI, HDMI and standard
composite analog video sources. The SDI and HDMI digital inputs provide active loop-through
connections while the composite input is self-terminating with passive loop-through.
Controls are conveniently placed on the front panel (computer not required). Menus are straight­forward and intuitive. Front panel headphone jacks allow monitoring of embedded digital audio
(SDI and HDMI) as well as analog audio (for composite video AV input). Large, three color tally
lights above each screen operate from standard GPI connections (contact closure or open­collector pull-down) for maximum compatibility with existing systems.

2. UNPACKING

Carefully unpack the M-LYNX-503 monitor and verify the following items are included:

Inspect the unit for any physical damage that may have occurred during shipping. Should there be
any damage, immediately contact Marshall Electronics at [phone]. If you are not located
within the continental United States, call [phone].

3. INSTALLATION

The M-LYNX-503 is designed to mount in a standard 19” equipment rack using the pre-installed
mounting ears. Once mounted, the monitor may be tilted to the ideal viewing position. Care
should be taken to allow suf cient slack in cables attached to the monitor so as not to bind when
the monitor is tilted. Also, check that the ventilation holes are not obstructed by other equipment
in the rack.

4-pin XLR DC power input compatible with typical broadcast television camera 12-volt power
