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:

1. M-LYNX-503 Monitor

Connections, Power On and Initial Setup

Note: Each screen has its own full complement of video input connections.

Power, TALLY and LAN connections go to all screens

2. Power supply with AC cord

3. Operating Instructions

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.

1. 4-pin Power Connector

4-pin XLR DC power input compatible with typical broadcast television camera 12-volt power
supplies. Caution: Some 4-pin power supplies provide 24 volts. These are NOT compatible with
this monitor. Please check the label on the power supply before connecting.

M-LYNX-503 / Operating Instructions

Plug the included power supply into an AC power source (100 – 240 Volts @ 50/60 Hz). Attach the
power connector to the back of the monitor. (Alternatively, a standard camera-type 12-volt power
supply with an XLR-4 connector may be used).
Connect the required cables for video signal input and output.
The monitor defaults to “ON” when power is connected. The Marshall name will  rst appear then
video will be automatically detected and displayed on the screen. If video does not appear, press
the INPUT button on the front panel to select an active source. HDMI and SDI inputs have active
loop through connections. Active loop-through does not work if main power is remove from the
monitor. Front power buttons have no effect on loop-through operation.

4. BASIC OPERATION

When main power is  rst applied to the M-LYNX-503, the input selection defaults to the last used
source. To see other sources, press the Input button to cycle through three choices: HDMI, SDI
and AV (composite analog).
Headphone audio level may be quickly adjusted any time by pressing the ◄ and ► buttons.
The power button for each screen is located just above the headphone jack. The button lights up
green when the screen is ON.
To con rm that main power is being supplied to the internal components, a red LED light for each
screen is visible through the ventilation holes on top.
