Installation Precautions

WARNING: This system has internal components which may be damaged by electrostatic discharge.

To protect yourself from harm and the internal components from electrostatic damage, be sure to observe the
following precautions when ha ndling or storing the system:

• When you disconnect the power cable from the socket, pul l on the plug not the cord.

• To help prevent electric shock, connect the power cable to a properl y wired and grounded

power source. Do not use adapter plugs or remove the grounding prong from the cable.

• Always connect any eq uipmen t used with the prod uct to properl y wired and grounded

power sources. Be sure to tighten all connector screws.

• Reliable earthing of this equip ment must be maint ained. Particular attention should

be given to supply conne ctions when co nnec ti ng to power str ips , rather than direct
connections to the branch circuit.

• Do not connect or disconnect this product during an electrical storm.

• Do not place any object on the cables that might cause the cables to make sharp bends or that

affect the integrity of the cables. Be sure that cables are not located where they can be
stepped on or t rippe d over.

• Route all wiring and cabling away from heat sources and sharp metal edges to avoid

damage.

• Keep product away from direct sunlight and heat sources. Hot air may cause damage to

the cabinet and other parts.

• Install the product in a well-ventilated area . Do not block ventila tion slots and openings

with objects.

• Do not allow metal pieces or obj ects of any kind to fall into the ventilation holes. Keep the

ventilation holes and openings clean. Vacuum openings if you notice dirt accumulating on
them.

• Handle the product with ca re. The di splay may contain gla ss parts. Dropping the product

may cause any glass parts to break.

• To help protect the product from sudden, transient increases and decreases in electrical

power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).

• Consideration should be given to t he connectio n of the eq uipment t o the supp ly circuit a nd the

effect that circuit overloading might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addre ssing
this concern.

• The ambient temperature within the rack may be greater than room ambient. Installation

should be such that the amount o f air flow required for safe operation is not compromised.
Consideration should be given to the maximum rated ambient.

• Installation should be such t hat a hazardous stability co ndition is not achieved due to

uneven loading.

Trenton Systems, Inc. ii

TMM4500 Ref er ence Guide

Rack Mounting Precautions (Where Applicable)

The following safety gu idelines are provided for all rack-mountable equipment:

• Maximum operating ambient temperature is typically 50 °C.

• Never restrict the airflow through the devices’ fan or vents.

• When installing equipment into a rack, distribute the units evenly.

• Otherwise, hazardous conditions may be cre ated by an uneven weight distribution.

• Connect the unit only to a properly rated supply circuit.

• Reliable earthing (grounding) of rack-mounted equipment should be maintained .

ACK MOUNTING

R

The TRC4012 system can be installed in a rackmount cabinet that conforms to EIA standards for computer
equipment with 19-inch wide panels. The cabinet must be tall enough to accommodate the computer’s
height and deep enough to accommodate the system’s depth, while providing the proper clearances for air
flow and cabling. A cabinet with a standard depth of 31.5 inches (800mm) should be sufficient ; however, a
rack with a non-standard depth dimension of at least 22 inches (559mm) will provide the suggested
minimum front and rear chassis clearances needed for an installation.

The TRC4012 is designed to be supported in the cabinet with rack slides or placed on a cabinet shelf. The
front flanges of the computer are designed to secure the TRC4012 to the rack cabinet’s front mounting rails

ACKMOUNT INSTRUCTIONS

R

A) Determine the mo unting location within the ra ck and mark the mounting holes in the front and
rear of the rack enclosure accordingly (this is for easy reference while you are mounting the equipment).

NOTE If instal ling by yourself or even with a helper, just b elow where you are going to mount the unit
install 2 of the 10-32 screws (or M6 if using an alternate r ack) in the front mounting sur face leaving at
least 1/4” inch of thread exposed . This will act as a wrest to assist holding the unit in place when
installing the unit.

B) Install the rear “L” mounting brackets to the rear face of the enclosure using 4x 10-32 Panhead
Screws set at the desired height/location.

C) Find the target installation depth by measuring the front face/mounting surface of the rack to
center- line of the mounting hole of the rear “L” mounting bracket.

D) The measurement from the front ear to the rear arms elongated mounting holes must be the same
length as step 3. Some adjustment of the aluminum support arms is likely needed ensure a proper fit. To
adjust the arms use the Hex Head tool to loosen or remove the Pancake screws as necessary until the
elongated holes of the arms match the measurement. Once at the correct measurement then once again
secure the arms in place.

3-1 Trenton Systems, Inc.

TMM4500 Reference Guide

NOTE: The arm may need to be adjusted to the next set of mounting holes to fit correctly.

E) S lide the rack mount unit straight into the rack ( if following the TIP you can wrest it on the screws
you previously installed in the front) and secure the rear arms into the “L” brackets with the provided 10-32
Panhead screws.

F) With the re maining 10-32 screws, secure the unit into the Rack Frame. (Removing the 2x 10 -32
screws you were using as stops in the TIP a nd install them i nto the remaining hold of the rack ears). Ensure
the unit is level and then tighten all of the 1 0-32 screws.

G) Your equipment should now be mounted in the rack.

NOTE: This is a general insta ll gu ide. Actual rack mount install may vary from unit to unit. For
additional assistance please contact Trenton Systems technical support

CAUTION

Ensure that the TMM4500 is securely mounted in the component

rack before opening and extending the display drawer.

The display head of the TMM4500 contai ns the majo ri ty of the unit weight. Failure to secure the unit before
sliding open the display drawer will cause the unit to tip forwa rd and may result in system damage or injury.
For pre-installation, testing situations the back of the unit should be secured to a stable surface or countered­weighted to prevent the unit from tipping forward.

Follow the steps below to open the TMM4500 display drawer, slide out the display assembly and rotate and

Chapter 5 - Unified Button Board Operation

The TMM4500 includes an On-Screen Display (OSD) button board for use with multi-display systems. In
the past each panel required its own OSD button board and controls to manage the basic display functions.
The single unified OSD button board mounted on the center screen allows the user toggle control
functionality of each individual display or all of the panels at once. This single OSD management feature
brings a ne w level of control to multi-screen display systems.

BUTTON BOARD LAYOUT

The OSD button board located on display screen one (1), i.e. the center display screen, is illustrated below.

The basic functions of the OSD button board are:

• Power Button – Turns the TMM4500 on and off

• Menu – Activates the OSD set-up menu

• Navigation & Hot Keys, Up Arrow – Brightness

• Navigation & Ho t Keys, Down Arrow – Auto-Calibrate (VGA Only)

• Navigation & Hot Keys , Left Arr o w – Contrast

• Navigation & Hot Keys, Right Arrow – Activates Volum3

INDICATOR LIGHT DEFINITIONS
