Chapter 1
Installing InView Marquee
Message Display
Section 1.1 Introduction
These instructions show you how to change the serial address, and how to mount
InView series signs with NEMA Types 4, 4X, and 12 enclosures. These signs are
intended for indoor or outdoor use depending on the NEMA standard.
• Type 4 enclosures are intended to provide a degree of protection against
windblown dust and rain, splashing water, and hose-directed water.
• Type 4X enclosures are intended to provide a degree of protection
against corrosion, windblown dust and rain, splashing water, and hosedirected water.
• Type 12 enclosures are in a sealed case that is, dust free, gasketing, and
spray-down resistant.
Section 1.2 Wire and Safety Guidelines
Install the InView display conforming to NFPA 70E, Electrical Safety
Requirements for Employee Workplaces. In addition to the NFPA general
guidelines, refer to the following.
• Careful cable routing helps minimize electrical noise. Route incoming
power to the module by a separate path from the communication cables.
NOTE
You can configure your InView Messaging software without having an
InView display connected.
• Where communication and wire paths must cross, make their intersection
perpendicular.
• Grounding helps limit the effects of noise due to electromagnetic
interference (EMI). To avoid problems caused by EMI, properly ground
all equipment and use shielded cables.
EXPLOSION
HAZARD
Identifies information about practices or circumstances that can cause
an explosion in a hazardous environment, which may lead to personal
injury or death, property damage, or economic loss.
1-2 Chapter 1: Installing InView Message Display
User’s Manual 0300277-02 Rev. D
AVERTISSEMENT
Actions ou situations risquant de provoquer une explosion dans un
environnement dangereux et d’entraîner des blessures pouvant être
mortelles, des dégâts matériels ou des pertes financières.
NOTE
Power wiring must be in accordance with Class I, Class II and Class III
Division 2 wiring methods (Articles 501-4(b), 502-4(b) and 503-3(b) of
the National Electrical Code, NFPA 70) and in accordance with the local
authority having jurisdiction.
Section 1.3 Change the Serial Address
A serial address for an InView sign is a number from 1 to 254 in hexadecimal (01
to FE). All signs leave the factory with a default address of 1 or 01.
This serial address is resident in the InView display and is used for RS-485
networking. If one of the factory network communications modules are used
(2706-Pxxx-SCx), this serial address is typically left at its factory default and the
network node or IP address is set in the factory network communication module.
Section 1.4 Checkout Procedure
After you install a sign according to the Electrical and Mounting Instructions,
make sure the sign is installed properly by applying power to it. The following
information should be displayed on the sign.
• Firmware part number and version letter (xxxx).
• Amount of RAM in the sign, (256 K).
• Serial address of the sign (a number from 01 to FE or from 1 to 254).
WARNING
Hazardous voltage.
Contact with high voltage may cause death or serious injury.
Always disconnect power to sign prior to servicing.
AVERTISSEMENT
Tension dangereuse.
Tout contact avec une tension élevée peut entraîner la mort ou des
blessures graves.
Déconnectez toujours l’alimentation de l’afficheur avant toute
opération de maintenance.

User’s Manual 0300277-02 Rev. D
To connect the 2706-P42-SC and 2706-P44-SC displays:
1. Remove the power supply cover by unscrewing its six screws.
Save the screws for a later step.
NOTE
It is recommended that you install power and serial wires at the bottom of
the power supply enclosure to reduce noise from power wires crossing
serial wires.
You can install the power or serial wires at the top of the enclosure if
necessary.
2. Remove the left or right conduit hole plug from the top of the enclosure
by removing its wing nut inside the enclosure.
Save the hole plug for a later step.
3. Insert the power wires through the left conduit hole on either the top or
the bottom of the sign.
NOTE
Use watertight conduit connectors only.
Also, only use flexible conduit.
1-4 Chapter 1: Installing InView Message Display
User’s Manual 0300277-02 Rev. D
4. Strip the wires back 6.35 mm (1/4-in.). Connect the incoming electrical
wires.
NOTE
Be sure to place the wires so they are not caught by screws when replacing
the power supply cover, and also so that they do not interfere with fan
operation.
5. Insert the serial wires through the right conduit hole on either the top or
the bottom of the sign.
NOTE
TB1 may be used for incoming serial connections for RS-232 or RS-485.

IN007B-EN-P) for more information about RS-485 end-of-line,
terminating resistors.
NOTE
Be sure to place the wires so they are not caught by screws when replacing
the power supply cover, and also so that they do not interfere with fan
operation.
To maintain NEMA compliance, and to prevent EMI emissions, install
hole plugs in any open conduit holes in the power supply enclosure. If
needed, an extra hole plug is shipped with the sign, in addition to any
hole plugs removed in step 2 of this procedure.
8. Replace the power supply cover using the 6 screws removed when the
cover was removed.
9. Torque the screws to 2.7 Nm (24-lb in.).
10. Connect the power cable to a power source.

10. Match the alignment holes of the brackets on the sign with the alignment
holes of the brackets on the wall so that the sign is at the desired viewing
angle.
NOTE
The second mounting bracket is shown here for illustration only. It is
actually mounted to the wall.
11. Fasten the mounting brackets together using two 10-32 × 3/4 Phillips
screws, two 10-32 washers, and two 10-32 lock nuts through selected
alignment holes on each end of the sign.
