Introduction to DX LCD Display
Introduction
The DX LCD Display unit is a person/controller interface used with
the DX-9100 series of controllers. The display can act as a simple
adjust and indication unit or be used for more complex tasks often
associated with a workstation. The display is designed for the
maintenance person who needs a straightforward way to monitor and
adjust points in a controller without being limited in capability. This
chapter gives an overview of the DX LCD Display.
Note: In this guide, Building Automation System (BAS) is a
generic term, which refers to the Metasys® Network,
Companion ™, and Facilitator™ supervisory systems. The
specific system names are used when referring to system-
specific applications.

DX LCD Display
Figure 2-1 shows the DX LCD Display.
Dxlcd_1
Figure 2-1: DX LCD Display
Use the display as either a portable, hand-held unit for use with more
than one controller, or it can be permanently mounted on the wall, on a
Universal Packaging Module (UPM) or in a panel as an integral part of
the controller application.
Features
The DX LCD Display:
• Stores up to eight configurations.
• Displays up to 8 pages of 12 points per page (up to 96 points) for
each configuration.
• Chooses the appropriate configuration to match the connected
controller.
• Allows you to configure the display unit to communicate with any
one of eight controllers connected to an N2 Bus, using the
appropriate configuration to match the selected controller.
No other supervisory system may be connected in this
configuration.
• Allows you to fully configure point data using the GX-9100
software configuration tool.
Introduction to DX LCD Display 2-3
• Indicates alarms both visually and audibly.
• Maintains an Alarm Summary of points currently in an alarm state.
• Maintains an Alarm Log of the last 96 alarm and return-to-normal
Changes-of-State (COSs) with time and date stamp. For the Alarm
Log feature to operate as described, the DX LCD Display must be
permanently connected to one DX controller.
• Displays Trend Data collected in the DX controller (if supported
by the controller).
• Allows you to define and change Time Schedule parameters.
• Allows you to define and change Optimal Start/Stop parameters.
• Allows you to set the system clock, date, and daylight saving
times.
• Includes sealed membrane keypad.
• Provides backlit, 240 by 128 pixel Liquid Crystal Display (LCD)
(equivalent to 16 lines of text with 40 characters per line).
• Displays graphical Home Pages with selected ‘live’ data that can
be customized according to Original Equipment Manufacturer
(OEM) or end user requirements.
• Allows use of the DX LCD Display as either a portable, hand-held
device or permanently mounted in a panel or on the wall. A wire
stand pulls out of the back of the display to set it at an angle on a
table top or hang it on a door panel during portable operation.
Theory of Operation
The DX LCD Display works with the DX-9100 (Version 2.0 or later)
and DX-9120 Series of digital controllers. The display connects
directly to the built-in RS-232 serial port of the DX controller,
allowing easy access to all of the system functions available at the
user’s password level.
A DX LCD Display unit with an earlier firmware version (2.x) can
communicate directly with one DX controller by a direct connection,
but not via the N2 Bus. The DX LCD Display with firmware starting
from Version 3 can use an RS-232/RS-485 converter (with plug
adapter) to communicate, via the N2 Bus, with one of up to eight DX
controllers working in standalone mode (that is with no supervisory
system monitoring the N2 Bus).
The DX LCD Display is operated through a keypad and menu system
to provide access to the data and parameters stored in the DX
controller.
2-4 Display Terminals
Note: In the remainder of this guide, the DX-9100 and DX-9120
controllers are referred to simply as DX controllers.
Display Configurations
Each DX LCD Display unit stores up to eight display configurations.
Different configurations customize the display as required for different
applications or situations. When defining a configuration you can
describe point names, point units, and digital (binary) state names, and
each configuration can indicate whether a specific point can be
commanded (adjusted or overridden) by the user of the display. Each
configuration specifies a graphical Home Page, allowing you to
display pictures such as a company logo or a system diagram. You can
map live data points to the Home Page as desired.
Each display configuration is identified by a configuration name and
configuration code. The configuration (i.e., application) stored in the
DX controller is also identified by a configuration code (also called the
User Config Code). When you attach the DX LCD Display to a
controller, the display unit attempts to match one of its stored
configuration codes with the User Config Code defined in the
controller configuration. If it finds a match, then the DX LCD Display
uses the corresponding display configuration. If it does not find a
match, it uses the default configuration.
In N2 Bus mode, the DX LCD Display unit matches the available
configurations to the DX controllers found on the bus.
Both DX controller configurations and DX LCD Display
configurations are defined using the GX-9100 Software Configuration
Tool, part of M-Tool. The configurations are then downloaded to the
controller or display unit through the serial interface.

5. If required, wire the alarm contacts (Pins 94-96) to the external
annunciation device (alarm horn). The circuit voltage must not
exceed 35 VAC/VDC.
Note: The alarm contacts are provided only on the DX LCD
Display, Version 3 (DT-9100-8104).
6. The VDC supply voltage already available at the DX controller
can power the DX LCD Display. Wire a supply voltage cable to
Pins 91-93, using the 24 VAC pin assignments shown in Figure
3-11.
Extending the Serial Cable with Line Drivers
Note: You can extend the RS-232 serial cable maximum distance
of 15 meters (50 feet) by using line drivers or leased line
modems. We recommend the ME800A-R2 Short-Haul
modem from the Black Box Company. The maximum
distance allowed between the two modems is 3.2 km
(2 miles). If you use shielded cable, the distance is reduced
to 1.1 km (0.7 miles).
To connect the two modems:
1. Use 4-wire 0.6…0.8 mm (24…22 AWG) unshielded twisted pair
telephone cable to wire the short-haul modems so Transmit +
(TX+) on one modem is wired to Receive + (RX+) on the other
modem and Transmit - (TX-) is wired to Receive - (RX-).
A ground connection is optional. See Figure 3-12.

Operating the DX LCD Display
Introduction
The DX LCD Display is operated through a simple keypad and menu
system interface that provides easy, intuitive access to the data and
parameters stored in the DX controller. It provides password

such as adjusting/overriding point values, editing time schedules, and
changing optimal start/stop parameters.
This section describes how to:
• establish communication with a DX controller
• connect to a DX controller via the N2 Bus
• display the Main menu
• display the Home Page
• enter a password
• view point data
• adjust/override points
• release overridden points
• view alarm summary

• set the clock
• edit Time Schedules
• define holidays
• change Optimal Start/Stop parameters
• view Trend data
• connect to another controller
