1-2 Introduction

1.2 Network Concepts

The concept of using LED technology displays as a cost effective, high impact
method of communication is rapidly growing throughout many industries and
businesses. The common thread of most requests is a means of programming and
controlling the displays in a variety of ways.

The Parking Garage displays can be controlled via wire current loop, fiber optic or
manual functions.

Current Loop (DataMaster)

The DataMaster controller connects to the Parking Garage display either from a j­box located outside near the display or from an indoor location. The communication
method is current loop to the host display, and from the host to the client. Current
loop is a standard communication method that uses a maximum cable length of 600
meters (approximately 2000 feet). Refer to Section 3 for additional information and
connections.

Current Loop (Signal Converter)

Two types of signal converters can be used in the case of some Parking Garage
displays. In each case the computer connected to the signal computer will be running
custom software for the displays. Refer to Section 3 for additional information and
connections.

In one case, a serial cable connects to the signal converter, and then current loop wire
will run to the display at a maximum length of 300 meters (approximately 1000 feet).

In the second case, a serial cable connects to the first signal converter, and fiber
connects it to a second signal converter. The fiber cable between displays can be up
to 1.2 k (approximately 4000 feet). From the second signal converter a current loop
wire can go another 300 meters to the display.

Manual Control Functions

In some cases, a manual switch box can be wired to the Parking Garage display to
either increment or decrement the number on the display. The switch box is outdoor
rated, and has a maximum length of 300 meters (approximately 1000 feet) from the
display.

1.3 Product Overview

DataTime and DataMaster Parking Garage displays are part of a family of
Daktronics LED digit displays designed for easy installation, readability, and
reliability.

The DataTime/DataMaster Series includes:

Parking Garage Display Specifications

There are two basic models in the numeric, or fixed-digit, parking display series: DF­1050 and DF-1051. Figure 2 and Figure 3 shows that both are modular displays, but
DF-1050 signs are typically used in a tower arrangement with end caps, while DF­1051 signs have a drop-in cabinet, designed for placement in an existing parking
garage structure, in a wall cutout or in a new custom sign.

1-4 Introduction

Figure 2: Model DF-1050

Because this series is based on a modular design, there can be any number of module
and caption combinations. Some displays may utilize a single module, while others
may consist of multiple modules arranged vertically. Each model has four digits that
can display the words “OPEN” and “FULL” as well as any number from 0 to 9999.
The text messages or numbers are controlled via signal protocol.

Caption modules are un-powered units that attach to the top or bottom of a digit
module. Caption modules all use permanent vinyl lettering. Some signs may also use
optional “blank” modules as filler or spacer panels.

Each section in this manual contains model-specific information, including physical
dimensions, digit configuration and power requirements. Display drawings, located
in Appendix A, also list dimensions, weight and mounting instructions for each
display. Additionally, model number and electrical requirements can be found on a
label located on the display's entrance panel.

The Parking Garage displays have been designe d for use with the Daktronics
DataMaster
Daktronics DataMaster parking garage so ftware and the appropriate interface. Refer
to Section 5 for detailed operating information.

1.4 Component Identification

The following terms include some of the more commonly used terms when referring
to these displays. Because Daktronics occasionally alters standard design to meet
customer needs, the actual display design may vary slightly from the illustrations
below.

This is only a brief overview. Refer to Section 4 for additional information on
maintaining the various display components.

Introduction 1-5

Client: The client display contains a client driver that receives signal from the “host”
driver on the Signal IN terminals. These drivers can re-drive signal to other client
drivers.

DataMaster Controller (DM100): The handheld keyboard like device used to set
the time, date, hold times, dimming etc. on the Parking Garage display. See Section

5 for more information on the DataMaster controller.

Display Address: The display address is an identification number assigned to each

driver in a network. The address is set using an 8-position binary switch on the driver
board. For single-line displays, the address will typically be “1”. For Parking Garage
displays with several levels, the top display is often set to address “1” and the others
are set to “2”, “3” etc. The address will be displayed each time the display powers
up.

Digit Circuit Board: The LEDs are mounted to a circuit board, which mounts to the
back of a digit panel. Problems with individual digits, segments or LEDs may require
accessing or replacing this board.

Host/Primary: The host display contains the host driver which relays signal directly
from the DataMaster controller on its Signal IN terminals. It is the only driver
connected to the temperature/photo sensor. The Signal OUT terminals are used to
connect the client driver. The host driver is selected by inserting the “Protocol-4”
plug into the protocol jack.

LED (light emitting diode): LEDs are high-intensity, low-energy lighting units.

Mirror/slave: receives a signal from the master but does not have a driver.

Power Supply: Converts AC line voltage from the load center to low DC voltage for

one or more digit circuit boards.

Protocol plug: The “Protocol-4” plug is inserted in the 5-pin protocol jack to select
the host driver for a set of host-client displays.

1.5 Daktronics Nomenclature

To fully understand some Daktronics drawings, such as schematics, it is necessary to
know how various components are labeled in those drawings. You will find this
information useful when trying to communicate maintenance or troubleshooting
efforts.

The following labeling formats might be fou nd on va ri o us Daktronics drawings:

• “TB _ _” denotes a termination block for power or signal cable.

• “E _ _” denotes a grounding point.

• “J _ _” denotes a power or signal jack.

• “P _ _” denotes a power or signal plug for the opposite jack.

Finally, Daktronics part numbers are commonly found on drawings. Those part
numbers can be used when requesting replacement parts from Daktronics Customer

3.1 Preparing for Power/Signal Connections

Reference Drawings:

Enclosed Driver, 4-col MASC, Wide............................Drawing A-191943

Electrical Specification Drawings............................. Refer to Appendix A

Electrical installation consists of the following processes:

• Providing power and ground to a disconnect near the display.

• Routing power and ground from the main disconnect to the display driver

enclosure.

• Connecting the ground to a grounding electrode at the display location.

• Routing the control signal cable from the control location to the display

location.

Electrical Specifications Drawings for displays in this series show the locations of

internal components and display signal and electrical access holes. Refer to these
drawings before making power and signal connections. All power and signal
terminates to blocks within the driver enclosure, immediately below the power
supply. Termination is to be completed by the customer's electrician to the power
terminal block (TB4). Refer to Drawing A- 19 1943.

3.2 Power and Grounding Connections

Correct power and grounding installation is imperative for proper display operation.
The subsections that follow give details of display power and installation. Only
qualified individuals should attempt to complete the electrical installation. Improper
installation could result in serious damage to the equipment and could be hazardous
to personnel.

Power

Daktronics DataMaster displays have been designed for easy access to components,
and to power and control signal hookup. Front panels ar e hinged to allow access to
the digits, cabling and other electronic components.

The DataMaster, Parking Garage displays require a dedicated, 120 VAC circuit for
incoming power. The display itself has no breakers or fuses.

Grounding

Reference Drawings:

Enclosed Driver, 4 Col MASC, Wide........................... Drawing A-191943

Displays MUST be grounded according to the provisions outlined in Article 250 of
the National Electrical Code and according to the specifications in this manual.
Daktronics requires a resistance-to-ground of 10 ohms or less.

The contractor performing the electrical installation can verify ground resistance.
Technicians from Daktronics Sales and Service offices can also provide this service.

The display system must be connected to an earth electrode installed at the display.
Proper grounding is necessary for reliable equipment operation. It also protects the
equipment from damaging electrical disturbances and lightning. The display must be
properly grounded, or the warranty will be void. Refer to Drawing A-191943, for
information on where to connect the grounding wire. Connection at the driver
enclosure terminal block is illustrated at the bottom of the drawing.

The material for an earth-ground electrode differs from region to region and may
vary according to conditions present at the site. Consult the National Electrical Code
and any local electrical codes that may apply. The support structure of the display
cannot be used as an earth-ground electrode. The support is generally embedded in
concrete, and if it is in earth, the steel is usually primed or it corrodes, making it a
poor ground in either case.

3-2 Electrical Installation

Power Installation

There are two considerations for power installation: installation with ground and
neutral conductors provided, and installation with only a neutral conductor provided.
These two power installations differ slightly, as described in the following
paragraphs:

Installation with Ground and Neutral Conductors Provided
For this type of installation, the power circuit must contain an isolated earth-ground
conductor. Under this circumstance, do not connect neutral to ground at the
disconnect or at the display. This would violate electrical codes and void the
warranty. Use a disconnect so that all hot lines and neutrals can be disconnected. The
National Electrical Code requires the use of a lockable power disconnect within sight
of or at the display.

Installation with Only a Neutral Conductor Provided

Installations where no grounding conductor is provided must comply with Article
250-32 of the National Electrical Code. If the installation in question meets all of the
requirements of Article 250-32, the following guidelines must be observed:

• Connect the grounding electrode cable at the local disconnect, never at the

display driver/power enclosur e.

• Use a disconnect that opens all of the ungrounded phase conductors.

3.3 Lightning Protection

The use of a disconnect near the display to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. The National Electrical
Code also requires it. In order for this device to provide protection, the power must
be disconnected when the display is not in use. The control console should also be
disconnected from power and from the signal j-box when the system is not being
used. The same surges that may damage the display's driver can also damage the
driver console's circuit.

3.4 Signal Connection

Reference Drawing:

Enclosure Driver, 4 Col MASC, Wide ..........................Drawing A-191943

Electrical Specification Drawings............................. Refer to Appendix A

To gain access to the driver enclosure, open the access door and remove the cover
from the enclosure. Refer to the Electrical Specification Drawings for the access
location for your sign.

Route power and signal cables into either side of the display, where there is a
separate knockout for signal conduit. The signal cable terminates to the signal
terminal block (TB3) in the driver enclosure, immediately below the power supply
and to the right of the power connectors. The component is a dual-row barrier
terminal block, and it accommodates “Signal In,” “Signal Out,” and “12 V DC Out”
as well as “Inc” (increment), “Dec” (decrement), “Open,” “Full” and “Common”
terminals for operating the display from switches.

Electrical Installation 3-3

Figure 7: DataMaster Driver Enclosure with 4-Column Driver

The customer's electrician completes the signal termination as shown on the
schematic, Drawing A-191943. Recommended signal conductor is 2-pa ir, 22 AWG,
stranded with shield (Daktronics part number W-1234), but 18 AWG may b e us ed as
indicated on the drawing. If the sign is to be operated from switches, this wiring may
be done using 22 AWG cable. Shielded cable is recommended if the switch wiring is
run next to other cables that may induce noise in the switch wiring.

Daktronics provides the protocol plug for the signal, and the customer may use
standard DataMaster software or may provide his or her own software.

Current Loop (DataMaster)

Reference Drawing:

Enclosure Driver, 4 Col MASC, Wide.......................... Drawing A-191943

A directly controlled display uses a current loop connection from the j-box at the
display to the driver enclosure in the sign. All the power and signal wiring terminates
at the driver enclosure. The DataMaster hand-held controller receives its power from
the display. The display layout is shown in Figure 8.

Note: The cable from the j-box to the display needs to be routed through conduit or
the display pole to protect it from weather or vandalism.

1. Mount the j-box near the display.

2. Route a 4-conductor cable through conduit

from the j-box to the driver enclosure in the
host display. (Distance limit from the j-box
to the display is 50 ft.)

3. Connect the signal/power cable from the j-

box to the driver enclosure as shown in

Figure 9 and listed in the table. Refer to
Drawing A-191943 for additional

information.

4. Using a DB9M to DB9F serial cable, plug

the DataMaster controller into the j-box

A typical control setup for parking garages will be one in which the signs are
controlled remotely from a booth or office in the facility. Signal cabling is similar to
wired, base-of-sign control, except that the controller requires a wall pack
transformer. The transformer plugs into both the hand-held controller and into a
120VAC outlet. The DataMaster controller also connects to a junction box to send
signal to the display, but the j-box will be located within the booth or office. The
operator then changes the display by entering current parking information and
operating instructions on the keypad of the DataMaster controller. For complete
details on sign operation, refer to Section 5.

Current Loop (Signal Converter)

Reference Drawing:

Enclosure Driver, 4 Col MASC, Wide ..........................Drawing A-191943

System Riser Diagram; DF Display, Parking Lot.........Drawing A-196787

A display, or set of displays, can be progra mmed using a current loop signal from a
signal converter. The signal into the display can be sent directly from the computer,
through the signal converter, and then into the display, or the signal can be extended
through the use of two signal converters. The following sections will explain the two
different communication methods.

Electrical Installation 3-5

Standard Wire Current Loop Setup

A standard wire connection requires a computer connected to a signal converter, and
then signal cable connected to the display. Refer to Figure 10 and Draw i ng A-

Manual Control Functions

Reference Drawing:

Enclosure Driver, 4 Col MASC, Wide.......................... Drawing A-191943

System Riser Diagram; DF Display, Parking Lot ........ Drawing A-196787

This is the simplest control
scheme, suitable for low cost
applications where an integrated,
remote control system is not
needed. Using the switches, a
four-digit display can be made to
count from 0 to 9999, blank, or
display ‘OPEN’, or ‘FULL’.
Data sent to the display from
third party software, or from the
DM-100 controller will override
the switch inputs. When the data
signal is removed, the display
will be blank until a switch
closure is sensed.

The signal will be sent using three wires from the switch box to the display. Refer to

Figure 14 and Drawing A-196787 for system layout.

1. The switch box has three pre-attached wires that will need to be connected
to the wires going to the display using wire nuts.

2. Using a 2-pair, 22AWG, cable, connect to the wires going to the display.
The maximum distance is 1000 feet.

3. Use the table and figures to connect the manual switch box to the display.

(Note: The switch box can control the display to either increment o r
decrement a number or to switch between open and full.)

As shown on Drawing A-19 19 4 3,
the terminal block inside the driver
provides connections for 4
switches: INC. (+1), DEC. (-1),
‘OPEN’ and ‘FULL’. Switch
control is implemented by wiring
from these terminals to normally
open switches, as shown on
Drawing A-196787. An optional
switch assembly containing
momentary toggle switches in an
outdoor enclosure is available from
Daktronics (0A-1279-0403).

3-8 Electrical Installation

Figure 14: Manual Control Layout

Figure 15: Manual Control Connections

INC. (+1): Closing this switch momentarily increments the count by 1. Holding

the switch closed will cause the display to increment rapidly. If the
count is at ‘9999’, incrementing will cause the display to blank.
Incrementing again will roll the count over to ‘0’.

DEC. (-1): Closing this switch momentarily decrements the count by 1. Holding

the switch closed will cause the display to decrement rapidly. If the
count is at ‘0’, decrementing will cause the display to blank.
Decrementing again will roll the count over to ‘9999’

OPEN: Closing this switch momentarily makes the display show ‘OPEN’. A

toggle switch may be connected to this input to hold it closed if it is
desired to have the display revert to ‘OPEN’ whenever the data signal
is not present.

FULL: Closing this switch momentarily makes the display show ‘FULL’. A

toggle switch may be connected to this input to hold it closed if it is
desired to have the display revert to ‘FULL’ whenever the data signal is
not present.

To Quickly Reset the Count to ‘0’:
Hold the INC. and DEC. switches closed at the same time until the count resets.

To Blank the Display:
Reset the count to ‘0’ and then decrement once.

Connecting Client Displays:

The display controller will transmit its display information on the “Signal Out”
terminals available inside the control enclosure. Any display, set to the same address
as the sending display, can receive this signal and show the exact same information.

3.5 Host/Client and Address Settings

Reference Drawing:

Enclosed Driver, 4-col MASC, Wide.....................................Drawing A-191943

Address settings, MASC drivers.............................................Drawing A-227502

Host/Client Definitions

One driver at each sign installation is designated as the “host driver.” This driver
receives its signal from the DM100 controller or signal converter. The “Signal OUT”
terminals are used to connect to “client drivers.” Refer to Drawing A-191943 and

Figure 16: Host, Signal Out to Client, Signal In

Electrical Installation 3-9

Figure 16 for an illustration of the host/client display connection.

Select the host driver by inserting the Protocol 4 plug into the 5-pin protocol jack
(J20.) For protocol jack location, refer to Drawings A-166216.

All other drivers in the display system are client drivers. These drivers receive signal
from the host driver on the Signal IN terminals and can re-drive this signal to other
“client drivers” on the Signal OUT terminals.

The address is an identification number assigned to each sign or display in a
network. Drawing A-227502 shows how to set the address on the drivers used in the
DataMaster and DataTime products. The control software uses the address to locate
and communicate with each sign. Because of the variety of installations using
DataMaster displays, addressing for each unit will be determined at point of sale or

installation. In general, a typical Level 1 parki ng
display would have an address of 1, a Level 2
would have an address of 2, and so on.

The address of each driver is set using an 8­position DIP-switch (S1), and the address is
based on that driver’s position in the sign or
display system. If a single-line sign is used, the
address will typically be Address “01.” This
means that switch 1 is turned “ON” and the
remaining 7 switches are in the “OFF” position.
This is the default address, set when each display
is shipped. In multiple-product displays, the
address determines which line of information is
shown on the driver’s digits. The switch is set
using a binary address. Use the table and the
examples for setting the address.

Figure 17: Common Address
Settings

Binary Address Settings

Note: Some older drivers set the address of each driver using an address plug
(Daktronics part # 0A-1279-0122) in J19. The address, either using a switch or a
plug, needs to be set for each driver.

Programs

To serve customers' repair and maintenance needs, Daktronics offers both an
Exchange Program and a Repair and Return Program.

Daktronics' unique Exchange Program is a quick, economical service for replacing
key components in need of repair. If a component fails, Daktronics sends the
customer a replacement, and the customer, in turn, sends the failed component to
Daktronics. This not only saves money but also decreases display downtime. The
company offers the service to qualified customers who follow the program
guidelines explained below.

Daktronics provides these plans to ensure users get the most from their Daktronics
products. Please call the Help Desk – [phone] – if you have questions
regarding the Exchange Program or any other Daktronics service.

When you call the Daktronics Help Desk, a trained service technician will work with
you to solve the equipment problem. You will work together to diagnose the problem
and determine which exchange replacement part to ship. If, after you make the
exchange, the equipment still causes problems, please contact the Help Desk
immediately.

If the replacement part fixes the problem, package the defective part in the same box
and wrapping in which the replacement part arrived, fill out and attach the enclosed
UPS shipping document, and RETURN THE PART TO DAKTRONICS. In most
circumstances, you will be invoiced for the replacement part at the time it is shipped.
This bill is due when you receive it.

Daktronics expects immediate return of an exchange part if it does not solve the
problem. The company also reserves the right to refuse equipment that has been
damaged due to acts of nature or causes other than normal wear and tear.

If the defective equipment is not shipped to Daktronics within 30 working days from
the invoice date, it is assumed you are purchasing the replacement part, and you will
be invoiced for it. This second invoice represents the difference between the
exchange price and the full purchase price of the equipment. The balance is due
when you receive the second invoice. If you return the exchange equipment after 30
working days from the invoice date, you will be credited for the amount on the
second invoice, minus a restocking fee.

To avoid a restocking charge, please return the defective equipment within 30
days from the invoice date.

Figure 24 illustrates the DM-100 insert used
to control the displays. If an insert
is lost or damaged, a copy of the insert
drawing, A-164998, can be used until a
replacement is ordered. The drawing is located
in the Appendix A.

To start the controller and begin programming
with the insert, refer to the following display
operation information. Read each subsection
carefully to fully understand the operating
procedures.

5.3 Parking Garage Display Operation

The DataMaster 100 controller can be configured to program information displayed
on the DataMaster Parking Garage sign. The console can program “OPEN” or
“FULL” for each level, or a numeric value, (9999-0), representing the number of
open positions. The instructions provided in this section discuss the functions the
operator uses to control the Parking Garage display.

In the event that the Parking Garage display malfunctions, refer to ED13481:

Frequently Asked Questions in Appendix B, and to the troubleshooting tables in
Section 4.4 of this manual. Both of those subsections detail measures that can be

taken to correct various problems.

Note: There is more than one way to reach certain LCD screens on the DM100. One
way is by using the menu and then the arrows to reach the desired programming
location. The other way is to set the first parking garage display and then continue to
enter though the additional screens.

Parking Garage Display Startup

To operate the DataMaster Parking Garage displays, the DataMaster 100 must first
be programmed to the parking functi o n. Use the <

DataTime®/DataMasterTM FAQ

The following frequently asked questions (FAQ) list was designed to provide DataTime or
DataMaster display owners with answers to common questions as well as additional
troubleshooting information. Reviewing this FAQ list before calling the Daktronics Custom er
Service Help Desk will result in a better, more complete information exchange.

Note: This FAQ refers to specific sections in following installation and operation man uals.

DataTime Outdoor LED Display Series:

Q. How do I know which driver is the “host” (that is, which driver connects to the

DataMaster

A. All driver boards are identical until you install the Protocol 4 plug. The driver

containing the Protocol 4 plug becomes the host. (Refer to the section titled Power
and Signal Connection of the manual.)

Q. Which driver do I connect the temperature and light sensor to?
A. Connect the sensor to the host driver only (the driver that is connected to the

DataMaster 100 controller).

Q

. I have a price display with multiple lines. Which line do I put the host driver

on?

A. You can designate any driver as the host driver by installing the protocol plug in jack

J20. Be sure to set the line number of each driver by installing the correct address
plug. Use the Signal Out terminals of this display to go to the driver on the next line.
Connect signal to all other displays using the Signal Out terminals of the previous
line. (Refer to the section titled Power and Signal Connection of the manual.)

Q. I powered up the display for the first time, and nothing happened; no digits lit

up or anything. What’s wrong?

A. First, open the display containing the host driver (the driver connected to the

DataMaster 100 controller). Is the green LED labeled POWER illuminated? If not,
the driver is either not getting 24 V DC, or there is a problem with the power supply
circuit on the driver board. If there is 24 V DC on J17, and J17 is secure, the driver is
defective. If the POWER LED is illuminated, check the protocol and address
settings.

Check to make sure that the protocol plug is loaded in J20 of the host driver. The
protocol plug should be installed only on the host driver (the driver connected to the
DataMaster 100 controller.)

If the host driver has power and the proper protocol and address settings, it will
always display something on power-up (it may be just an error code). If this does not
resolve the problem, the driver is probably defective. You can try swapping the host
driver with one from a different display. Make sure that the host driver always has a
protocol plug installed on J20.

Q. My sign is displaying “Ex” (x is a number). What’s wrong?
A. The driver displays error codes for common problems; refer to the Troubleshooting

section of the manual to resolve the problem.

Q. My sign is displaying garbage. What’s wrong?
A. Most likely the protocol and/or address plug settings are incorrect. The protocol plug

should be installed in jack J20 only on the host driver (the driver conn ected to the
DataMaster 100 controller). (Refer to the Power and Signal Connection section of
the manual.)

Q. I don’t want to show __ (°C/°F/time) on my Time & Temp display. How do I

remove this?

A. Use the DataMaster 100 controller to set the hold time for this item to 0.0.

Q. When I try to set the hold times on my Time & Temp display to less than 1.1

seconds, it doesn’t work. Why?

A. DataTime displays with driver software versions earlier than 2.0 did not support hold

times of less than 1.1 seconds. Versions 2.0 and newer do not have this issue.

Q: I just connected my DataTime display, and instead of showing temp, it shows an

error message. What's wrong?

A: Refer to Drawing A-166883 for temp sensor jumper settings and LED indicator

information. Refer to Drawing A- 16 6 21 6 for the 4-column MASC LED driver (or
appropriate 8- or 16-column driver specifications) for troubleshooting information.
The CAN RX and CAN TX LEDs should blink once every few seconds. If both
LEDs are on constantly, suspect the wiring between the MASC LED driver and the
temp/light sensor.

Q: I have a multiple line display and all lines of the display show the information

set on the first line. How do I get the correct information on each line of the
display?

A: The line number for the display is set using address plug J19. All displays ship with

an address plug that defaults to Line 1. The install kit includes a set of 12-pin Mate-

™

N-Lok
they should be installed. If a driver is located inside a display on a line other than
Line 1, remove the Address plug and install the corresponding plug to the line of
price data you would like to show.

Q: My Time and Temp display doesn’t keep accurate time. Every month I have to

reset the time. What’s up with that?

A: Signs shipped before 4/29/03 may exhibit this problem. It can be corrected by

installing a 60Hz reference retrofit kit (0A-1279-0283), and updating the driver
software to version 3.0 or newer.

The following table lists problems that have been found with older versions of the
display driver software. If you see this problem, look at the version label on the
MASC driver. If the version is earlier than the one listed in the fix column, this
driver needs to be sent back for reprogramming. Contact Daktronics Customer
