Commercial TV lntro
Commercial TV's differ from non-commercial TV's in many areas. One
in particular is external control of the TV from third-party interactive
systems. Today, most commercial applications incorporate a third-party
control system, Master Antenna Television System (MATV), and some
sort of interactivity.
Commercial TV's:
have to be adaptable to the different types of third-party
systems in use today.
have two setup menus, a basic menu and a master menu.
(The master menu allows more control of set operation and
limits access to features commonly found on the basic menu
of non-commercial TV' s.)
have an interface for a third-party controlling device.
incorporate spill-resistant cabinets, (all grills, seams or other
openingsare designed to minimize the likelihood of cleaning
agents or spills entering the instrument and causing
operational problems).
incorporate integral mounting provisions, (mounting bosses
on the bottom of the cabinet that allow affixing the instrument
to existing mounts, brackets, and plates).
have restricted access to channels and menus, front panel
lockout, IR and wired cloning, and de-commercialization
features. (De-commercialization prepares the commercial TV
for after marked resale.)
RCA commercial TV's are indicated by the letter Jat the beginning
of the model number and GE commercial TV's are indicated by the
letters GH in the model number. An example ofa RCA commercial
model number is J32430.
Commercial TV Application
Professional /Educational TV's arc mainly used in situations that
require televisions to always perform a particular function such as
always turn on with the volume preset and on the same channel. Certain
features and functions are enabled or disabled depending on the appli-
cation, in this application controlling of the TV externally, although
possible, is not common.
Lodging TV's are similar to Professional /Educational in that some
features are disabled and in some cases none of the TV's controls are
enabled, in a Lodging environment, the TV's are typically controlled by
an external device or set-top box connected to the Digital Serial
Communications lntert:ace (DSCI) jack. When connected to the DSCI
other devices can communicate with the TV sending it commands and
getting front panel or remote commands back from the TV. With this
interactivity, the user can send requests to the controller and do more
than the non-commercial TV. For example: Pay-Per-View and room
service can be requested by the customer using the on screen menu
system. The service can then be billed directly to the room account. This
type of interactivity can even include an itemized list of room charges
and advance checkout for the customer.

usesastandardstereoV4plug for controlling the TV. The pendant is a
wired remote control used to control basic functions of the TV. There
are two types of pendants; 1) Smart pendant and 2) "Dumb" pendant.
Smart pendants control TV on/off; volume, and channel +/- much like the
standard remote control does. The "dumb" pendant has channel up and
on/off capabilities only. Both smart and dumb pendants can incorporate
volume control of an external speaker and are hardwired to the TV.

Jack Panel
The jack panel is based on a particular application. Although
specific applications require specific jack panel connections, any
of the commercial TV's can be used in a commercial establishment.
The first commercial TV's only had the Pendant connection. As
commercial sets evolved, more interaction between user and the
TV became apparent. The DSCI was added to provide this type of
interactivity. Commercial TV's today have a pendant and or DSCI
port for external control of _he TV.
Note: The DS(T port and Patient Remote Pendant are not used at
the same time, Only one controlling device can be connected to
the TV at a time.

Healthcare Jack Panel
The healthcare jack panel uses the most basic of connections.
There are three connection jacks but only two are used at any given
time. The connections are:
1. Patient Remote Pendant
2. DSCI Port
3. Cable /Antenna
The Patient Remote Pendant uses a standard V4 stereo plug that
allows connection of a wired remote control unit called a pendant
to operate the TV.
The DSCI port uses an eight pin phone jack style plug to connect
the TV to a set-top box for controlling the TV and providing
interactivity.
The Cable /Antenna connection is for the coax cable used to
transmit the TV signal to the TV.

Figures L-3and L-4 can be found in profcssionaL, educational, or lodging
applications. These applications typically do not use the Patient Remote
Pendant jack. Both jack panels have the DSCL for controlling the TV by
an external system. The other connections are features that are used in
different applications.
The DSCL only jack panel has basic connections and is used in
applications that require DSCL, cable /antenna, and possible video
and audio input. It can also be used with a stereo system.
The connections are:
Video: Composite video input from a VCR, DVD,
camcorder, etc. connected to the TV.
Audio R/L/Mono: Audio signal from a VCR, DVD,
camcorder, etc. connected to the TV to provide audio
input when using composite video.
R/L Out: Audio signal out to a stereo system amplifier
used when higher volumes levels are required.
Cable /Antenna connection is for the coax cable used to
transmit the TV signal to the TV.
DSCI port uses an eight pin phone jack style plug to
connect the TV to aset-top box for controlling the TV and
providing interactivity.

Display Series Jack Panel
The display series jack panel has all the connections of the DSCI
only jack panel with two additional connections, PC input and S-
Video. PC input is for connecting a personal computer to display
computer graphics and text on the TV. S-Video is used when a
higher quality video is needed. When using S-video, the
corresponding audio in needs to be connected.
PC INPUT (Scan Converte O
The function of the built-in Scan Converter is to serve as an
interface between a computer and the television. This allows the
television to be used as a computer monitor. Using the PC INPUT
connector, the TV can accept the computer signal and convert this
signal into a standard NTSC Y/C signal for display on the TV
screen. Computer signals with resolutions up to 2048 X 1536 @
152 hertz vertical refresh are possible.

RemoteControls (Master & Basic)
A Master remote is different from a Basic remote in menu access only.
Master remotes have special coding to access the hidden or master menus
of the TV. Basic remotes can only access the basic menus that are
allowed by setup of the master menu. To setup a commercial TV
functions, the master remote or Clone PRO __jclone box needs to be used.
No other remotes can access the master menus. When using the basic
remote to make changes in the menu, each time the set is turned off. the
changes will return to the detZault settings when powered on. Changes
made by using the master remote will remain when power is removed
from the TV. These settings can only be changed back by using a master
remote or the Clone PRO TM. Aside from the special coding used to
access the master menu, the master remote is the same as the basic
remote.
appear to control the TV via 1R but are doing so through the DSCI input
on the back of the TV. These remotes are typically used where pay-per-
view systems are in place and require a set-top box for control. These
remotes do not have the coding to control the TV directly, but control the
set-top box instead. The set-top box then controls the TV via the DSCI
jack. Therefore, when the TV is not responding to remote commands,
check the set using the Clone PRO _Mclone box connected to the DSCI
port. if the TV responds to the Clone PRO _j, there is nothing wrong with
the TV. (Functions of the Clone PRO _Mmay be limited by the setup of
the TV and type of control the set-top box has. At a nfinimum, power on/
off should work.)
A Thomson universal remote is capable of many other operations that a
basic remote is not, for instance; programmable to other brands of VCR,
Cable/Sat, and audio systems. Like the basic remote, the universal can
access the basic menu but is not capable of getting into the master menu.
Universal remotes have the ability to control two Thomson TV's that are
in the same vicinity but independant of each other. TV 1and TV2 buttons
allow controlling two sets using one remote. See Master Menu section,
on page 15, for TVI and TV2 setup.
NOTE:
There are other remote hand units specific to some set-top boxes that

Basic Menu
The basic menus are accessed using the basic remote or the front
panel Menu button. The menus that are available, depend on the
restrictions set by the master user and the active input. For instance,
if Basic Menu Access has been set to Disabled in the Access and
Power Options menu, the basic menus will not be available.
Many of the changes made in the basic menu will revert to their
master menu settings the next time the TV is turned on. Most all
the basic menu items function the same as their master counter
parts. Refer to the users manual for more detailed operation of the
menu items that are different.
NOTE: Some.features, such as PC Video Input Controls, are not
available unless that input has been selected prior to entering the
menu. This holds true/or both Basic and Master Menus,

Master Menus
By using aMaster Remote or the Clone PRO ]Mthe Master "Main Menu"
can be accessed. The master menu sets up how the TV will operate for
the end user. It is important to be extremely familiar with the master
menu and what each feature does. Many times a problem that appears
to be set related is actually improper setup or a misunderstanding of the
menu item's function. Because of the numerous problems that can be
associated with improper menu setup, only the function of each menu
item will be explained.
The following section covers the master menu functions and what
each does. Navigation through the menu is in order of display.
NOTE: Some menu items may not be in all models.
