Installing the 6157 Industrial Monitor

This section describes how to install the monitor.

Tools Needed

In addition to the tools required to make the cutout, you will need the
following tools:

3/8” Deep Well Socket

•

1/4” Drive Extension - 12” or longer

•

1/4” Drive Ratchet or 1/4” Drive Torque Ratchet

•

Before Installation

When installing the unit, it is important to consider environmental
factors at the site that could affect performance as well as possible
effects from equipment operation on personnel and nearby equipment.

Following the guidelines will help ensure that the monitor will provide
safe and reliable service.

Ensure that sufficient power is available from a single phase AC

•

outlet at the site.
Ensure that sufficient space is available around air inlets and outlets

•

to provide the circulation necessary for cooling. Never allow air
passages to become obstructed. The monitor is equipped with a fan
to ensure proper cooling.

• Dust and smoke part icl es ca n ca us e pr obl ems , s ince they can collect

at ventilating holes in the enclosure and interfere with cooling.
Accordingly, wh ere dust and smoke are probl ems it is esp ecia lly
important to keep air vents clean. Refer to the Routine Maintenance
section (Page 20) for more information.

Ensure that the ambient air temperature will not exceed the

•

specified maximum temperature. A user supplied fan, heat exchanger
or air conditioner may be required to meet this condition in some
installations.

Leave the m onitor’s enclosure or cover in place at all times during

•

oper ation. The c over affords prote c tion agai nst hig h voltages inside
the monitor and inhibits radio-frequency emissions that might
interfere with other equipment.

The Federal Communications C ommission has prepa red a pamphlet

•

that addr esses the pr ob lem of radio frequency interference to radio
and televisio n receptio n, which should b e consu lted i n c ase of
problems with such interference. This publication, “How to Identify
and Resolve Radio/TV Interference Problems” (Stock #004-000­00345-4) may be obtained from the US. Government Printing Office,
Washington, DC 20402.

Publication 6157-5.1

6 Industrial 20" CRT Monitor

Determine the mini mum and maximum ambient humidity for the

•

monitor by consulting the specification sheets at the back of this
manual. Ensure that the humidity of the ambient air will not exceed
these limits. In very dry environments, static charges build up very
rea dily. Proper groundi ng of t he equ ipment through th e AC pow er
cord can help reduce the likelihood of static discharges, which may
cau se shoc ks and damage e lectronic c omponents.

Panel Mounting

When properly installed, the 6157 Industrial Monitor is designed to
pr ovide prot ection agai nst wa ter a nd dust to NEMA 4, NEMA 4X
(plastic panel), and NEMA 12 standards.

No slides or shelves are required because the 6157 Industrial Monitor is
designed to be supported by the panels in which it is installed.

Industrial 20" CRT Monitor 7

Panel Mounting Guidelines

Observe the following precautions before installing the unit in a panel:

Confirm that there is ad eq uate spac e behind the p anel. Rememb er to

•

allow extra space (3 in. (76.2 mm) behind and 1 in. (25.4 mm) below
and on each side) for air circulation.

Confirm that the cabinet is deep enough to accommodate the

•

monitor's depth while providing rear clearance for airflow. A cabinet
with depth of 23.11 in. (587 mm) is sufficient.

Take precautio ns so tha t meta l c utti ngs do not enter any c ompone nts

•

that are already installed in the panel.
Supporting panels should be at least 14 gauge to ensure proper

•

sealing against water and dust and to provide proper support. The
mounting hardware supplied accommodates panels up to 0.25 in.
(6.35 mm) thick.

Note:

Supporting panels must be cut and drilled to
specifications prior to installation.

ATTENTION: Failure to follow these warnings may
result in personal injury or damage to the panel

4. Tighten the captive screws on the cable connector to secure it.

Connecting AC Power

The 6157 Industrial Monitor requires a single phase power supply
providing 90 to 264V AC at 47 to 70 Hz. Power must be available at a
grounded three-pi n outlet locate d nearby. Whenever possible, connect
the monitor to the same AC source that supplies the computer.

To connect AC power to the monitor:

1. Turn off the mai n switch or breaker.

2. Use the ground terminal of the monitor to establish a chassis-to-earth
ground connection. Secur e one en d of a grou nd strap t o the ground
termina l. Conne ct th e other end of t he ground strap to a good earth
ground.

The ground terminal is an M5 screw.

A TTENTION: Chassis ground must be connected for
safe operation of the monitor. The AC receptacle on the
monitor is a 3-wire type with chassis ground pin, and the
mating AC cord supplied is a 3-wire type, designed for
connection to a grounded 3-pin AC outlet. However, a
properly ground AC ou tlet is not always avai lable, and
grounding using a 3-wire cord can easily be defeated. If
you fail to ground the monitor properly, the setup may
resu lt in p ersona l injury fro m e lectric al shock or damage
to the equipment.

Operat i n g th e 6157 Industrial Monitor

This section describes how to operate the 6157 Industrial Monitor.

Controls

The f o llowi n g is a summary of the controls and indicators on the
membrane keypad on the 6157 Industrial Monitor:

Figure 6
Monitor-Re sident Control s

Note:

The number of controls supported by the monitor may vary
depending on the monitor type or customer-specified
options.

Status LED Indicators

The keypa d includes seven green L ED in dicators and one amber LED
indicator. These provide information about the current status of the
monitor.

When the monitor is operating in normal mode, one of the green LEDs
will be lit. The monitor indicates an error condition if more than one
gre e n L E D is lit, or if only the amb er SCF LED is lit.

Note:

Saving Changes

When you finish adjusting the monitor’s settings, the monitor
automatically saves your changes. Approximately 20 seconds after you
stop pressing controls, the amber SCF LED blinks twice to indicate that
your changes were saved.

For information on troubleshooting the 6157 Industrial
Monitor, refer to Page 23.

Publication 6157-5.1

Industrial 20" CRT Monitor 17

Manual Degauss

The monitor is equipped with an automatic degaussing system to remove
residual magnetism from the CRT’s shadow mask at power-up.
Degaussing helps keep the screen free of any color impurities which
might otherwise result from magnetism picked up by the shadow mask
from the earth’s magnetic field when the monitor is moved.

In addition, a degauss push button is provided on the control panel. This
manual control can be us e d if col or impurities appear on the screen wh ile
the monitor is in operation.

Note:

Tip: For best results, perform a manual degauss only after allowing at
least 15 minutes to pass following power-up or a previous manual
degauss.

The internal degauss will not prevent color impurities
caused by local ma g netic fields. Metal encl osu res can
easily become magnetized by welding and machinery
operations.

Use a hand held degaussing coil to remove residual
magnetism from the enclosure.

Brightness and Contrast

The 6157 Industrial Monitor is equipped with adjustable brightness and
contrast c o ntrols. Th ese controls are located on the front panel of the

unit.

To obtain the best display, first set the brightness control to the
appropriate setting under the lighting conditions in which the monitor
will be used. Then adjust the contrast control to increase or decrease the
intensity of the video imag e as required.

To set the brightness and contrast controls:

1. Press the Select Mode button until the status LED indicator below
the Brightness icon is lit.

Note:

2. Use the left arrow button to adjust the brightness value to its lowest
setting.

3. Use the right arrow button to adjust the brightness until the black
colors in the screen image change from black to dark gray.

For best results, display a screen image with a large
black area before setting these controls.

Publication 6157-5.1

18 Industrial 20" CRT Monitor

4. Use the left arrow button to lower the brightness until the dark gray
colors change back to black. This is the optimal brightness setting
given the current lighting conditions

5. Press the Select Mode button until the status LED indicator below
the Contrast icon is lit.

6. Use the left and right arrow buttons to change the value for the
contras t contr ol to achieve t he appropr iate level of i ntensity in t h e
image.

Horizontal and Vertical Size and Position

The mo nitor is fa c tory preset and normally requires no manual
adjustment for vertical or horizontal alignment. However, four
adjustable size and position contr ols are provide d to permit adjustment if
it should become necessary.

To change size or position:

1. Press the Select Mode button until the status LED indicator below
the a p propriate icon is lit .

2. Use the left and right arrow buttons to change the value for the
selected control.

Raster Rot ation

A ra ster rotation contro l allows for c orrectio ns to any disp lay
misalignment which might be present as a result of interaction between
the monitor and an external, low-level uniform magnetic field, such as
th e ea r t h ’s ma g netic fi e l d.

All C RT displays are affe c ted by the earth’s magn etic fi e ld and by
simi lar low level uniform fields. Ge nerall y, th e eff e c ts of su ch a field on
the display vary with the display’s spatial orientation relative to the field
lines. For example, wh en th e unit’s screen is faci n g west, t h e effects of
the earth’s field are minimal. When the screen is rotated toward the north
or south, the disp lay ca n exhibit a small amount of rota tion, so that its
top and bottom edges are no longer parallel to the edges of the panel.

Note:

This effect is differ ent from the effect of magn etis m on th e
shadow mask, which takes the form of color impurity and is
corrected b y th e d egau s s ing system.

Publication 6157-5.1

Before making any adjustments, display a f ull scre e n image a n d chec k
for rotation (top or bottom edge of the image out of parallel with the
corresponding edge of the panel).

Industrial 20" CRT Monitor 19

To change raster rotation:

1. Press the Select Mode button until the status LED indicator below
the raster rotation icon is lit.

2. Use the left and right arrow buttons to adjust the rotation.

Important:

The raster rotation control cannot correct for the effects of
external AC fields such as those produced by large motors,
generators a nd trans formers. Such eff ects often take the
for m of display jitter. Protectio n agai nst this kind of
magn etic interf erence requires sp ecial sh ieldin g.

Secondary Control Function Mode (SCF) for Vertical
Pincushion

The 6157 Industrial Monitor allows you to adjust the vertical pincushion
to straighten the sides of the screen. You adjust the vertical pincushion
by switching the monitor to sec ondary control function mode.

To change the vertical pincushion:

1. Press the arrow buttons simultaneously to enter secondary control
function mode.

The SCF status LED indicator and the brightness LED indicator are
lit to indicate secondary control function mode.

2. Use the left and right arrow buttons to adjust the value.

Note:

3. Press the arrow buttons simultaneously to exit secondary control
function mode.

To best observe the effects of the vertical pincushion
adjus tment, disp lay an approp riat e full-sc reen i mage on
the monitor.

Description

Setting Up the Touchscreen Interface

All touch controllers are configured by default to provide serial
communications at 9600 baud, 8 data bits, 1 stop bit, no parity.

For Allen-Bradley monitors equipped with touchscreens, a serial
communications cable is requ ir ed. A suit able cable can be obta i n ed fr o m
Rockwell Automation or you can create one.

The cable provides a communications channel between the touchscreen
controller, which is mounted inside the monitor, and an RS-232-C serial
port on the host computer. Because the touch controller obtains power
from the monitor's power supply, no external touch power connections
are necessary.

Software supplied with the touchscreen must be loaded on the host
computer to handle communications with the touch controller over the
channel.

Because t he touchscreen emu l ates a mouse, there may be c ompa tibili ty
issues involving how the touchscreen emulates mouse buttons, especially
multiple buttons. For a complete discussion of these issues and how to
troubleshoot them, refer to the touchscreen documentation.

This section describes how to set up the touchscreen system using the
6157 Industrial Monitor. Setup involves the following:

• Enabling the touchscreen interface

• Installing the software on the host computer that will handle

communications with the touchscreen controller

• Performing a calibrati o n

Enabl ing th e To uchscreen Interf a c e

The 6157 Industrial Monitor provides a female DB-9 connector on the
rear panel. This connector provides the serial interface for the touch
controller.

Installing the Touchscreen Driver Software

To install the touchscreen driver software correctly, obtain the following
information about the host hardware:

The COM port in use for the touchscreen. Ensure that the RS-232

•

cable is properly installed between the monitor port and the host’s
COM port.

The baud rate at wh ich the controller is oper ating. You will need to

•

match the baud rate at the COM port. The controller baud rate is
factory set at 9600.

Note:

Once you have obtained this information, install the software using the
installation disks found in the touchscreen accessory package.

If you are using older touchscreen software, you may be
prompted for the type of touchscreen controller being used.
The 6157 uses the following controllers:

Resistive: Elo TouchSystems model E271-2210.

•

Ca paciti ve: MicroTouch model SMT-3.
