The displays are offered as single-face (one-sided) units which may consist of a number of
separate sections. Two types of display sections are used, one called the “master” and the
other an “echo.” Master sections contain the controller board which receives information
from the computer. Echo displays do not contain a controller board and require a master
display to operate. Displays show information from a third party source, such as a wire
service, ticker input, or Internet service, and scroll these messages from right to left on the
display. A generic KE-1010 setup is illustrated in Figure 2.

Introduction 1

A module is the building block of the DakTicker display.
By placing modules side-by-side, a display of any length
can be designed and built. Individual modules can be
easily removed from the display, if required
modules consist of an array of LED (light emitting diode)
pixels that are available in several matrix sizes. The
height options include 16-pixels high and 24-pixels high
as well as a twin ticker with two separate sections of 16
pixels high. Text can be configured into one large font or
two to three lines of smaller fonts, as shown in Figure 1.
Tickers are available in tri-color (red, green and amber) characters.

1.2 Drawing References

2.1 Support Structure Design

DakTicker KE-1010 displays are generally mounted on the wall or from the ceiling. Support
structure design depends on mounting methods, display size, and weight. (Figure 5). The
structure design is critical and should be done only by a qualified individual. It is the
customer’s responsibility to ensure that the structure and the connectors are adequate. Refer
to the Shop Drawings listed in Appendix A for dimensions and mounting clip locations.

Attaching or hanging anything from the display will render the warranty null and void.

Figure 5: Mounting Options

Mechanical Installation 3

2.2 Display Mounting

• It is the customer’s responsibility to ensure that the installation will meet local
standards.

• The mounting hardware must be capable of supporting all components to be
mounted.

Daktronics recommends either a wall mount or hanging mount method (Figure 5).
Remember to have all mounted displays inspected by a qualified structural engineer.

Ceiling Mount

Splice bars, provided by Daktronics, have 3/8"-16 UNC holes that can be used
to secure the ticker displays from a ceiling or other overhead structure. Use the
middle hole only when using the splice bars for mounting. Daktronics does
not provide the ceiling mounting supports. To hang a ticker, refer to Drawing

A-118572 and the following instructions:

1. Determine and mark the locations where the ceiling mounting

supports will attach to the overhead structure. The supports, when
installed, should form a 90-degree angle with the top of the display
(Figure 6).

2. Install the supports. Qualified personnel must approve the ceiling

mounting supports. Daktronics is not responsible for ceiling mounting.

3. Secure the splice bars to the supports.

4. Carefully hang each display by fitting the channel on the top of the

display over the splice plates and slide it into place (refer to Drawing
A-118572). When multiple sections are used, each joint between

displays must have hanging support.

Figure 6: Ceiling Mount

4

Wall Mount

The wall mount method includes the installation of Z-brackets to hold the
mounting clips attached to the back of the displays. Refer to Figure 7.

1. Determine the desired location of the top of the ticker display. Refer

to Drawing A-234483.

2. From the desired location for the top of the display, measure down

the distance listed in the chart following or Drawing A-234483. This
is the height location where the bottom Z-bracket is going to be
attached to the wall.

3. Determine the desired location of the end of the ticker display.

Measure from this point 3/4” in toward the display body if the
display has an endcap, or 1/2” if an endcap is not present.

4. Mount the bottom Z-bracket at this location.

5. Once the bottom Z-bracket is mounted place the metal spacers

(provided by Daktronics) on top of the bottom Z-bracket. Be sure the
arrow points up.

6. Mount the top Z-bracket so that the bottom of the bracket touches the

top of the spacer and the ends align with the bottom bracket.

Mounting Multi-section Tickers

The echo sections are shipped without end caps. Remove the left outer end cap from the
master ticker and attach it to the left-most echo ticker (refer to Figure 8).

Figure 8: Master-Echo Installation Detail

1. Before attempting to connect the sections, check their mounted alignment in relation

to each other. If the alignment is off, then adjust the mounting clips on the back of
the tickers.

2. Hang each section according to the appropriate mounting directions.

3. Refer to Section 3 for routing power and Section 4 for signal installation to each

section.

4. Slide the sections together.

5. Slide the splice bar over the joint(s) between the displays.

6. Tighten the screws (provided in the splices) using a 3/16" hex wrench.

Section 4: Signal Installation

To display messages on a KE-1010 display, signal is sent from the computer to the ticker via one of
two possible network systems: RS-422 or Ethernet. Signal is received by the controller board inside
the master section of the ticker. The controller board processes the data and relays it to the shift card.
The shift card relays signal to the modules, then the appropriate LEDs create the messages which
scroll across the ticker display.

4.2 Section to Section Connections

The signal between the master and echo sections is connected using 20-pin ribbon cables
between the shift board and the last module of the previous section (Figure 15). Follow these
steps to connect display sections.

1. Carefully hang the echo section(s) as described in

Section 2.2. Do not yet slide the sections together.

2. A ribbon cable should already be plugged into the

“Signal In” jack on the shift board (Figure 14) of the first
echo section. If it isn’t, do so at this time.

3. Plug one end of the ribbon cable into the “Out” jack on

the back of module A101 (the left end module) of the
master section.

4. If an echo section is present, plug P42/P43 of the echo

section into J42/J43 of the master section to complete
the interconnection of power. Repeat this for additional sections. Note: Total display
length cannot exceed 20 feet per power cord.

5. The connection for a master to one echo is shown in Figure 15. Repeat steps 1 though

3 to connect and hang each consecutive echo ticker. All other internal wiring
between modules has been done by Daktronics.

Figure 14: Shift Board

Figure 15: Master to Echo Connection

4.3 Master to Master Connections

In some cases, more than one master display is used instead of the master-echo
configuration. In this case, signal can be transmitted between master displays using a flipped
6-conductor RJ11 cable running RS-422. To connect multiple master displays:

1. Signal into the first display can be either RS-422 or Ethernet.

2. Connection between displays will always be RS-422. Connect from RS-422 OUT on

the first display to RS-422 IN on the second display (Figure 16).

3. Master displays connected in this way will need to have different addresses set on

each controller.

6.2 Removing the Face Panel

The internal components of the KE-1010 displays may be accessed after the face panel and
modules are removed. Refer to Figure 19 for a visual diagram of the steps involved in
removing the face panel. Never attempt to lift the entire display or carry the face panel using
the suction cups.

To remove the face panel:

1. Disconnect power to the display.

2. Using the suction cups provided with the display, slide the face panel up toward the

top of the display (Figure 19).

3. Pivot the bottom edge of the panel out of the support groove. The face panel should

now be free of the display cabinet.

4. Carefully remove the face panel. The LED modules will now be accessible.

5. Remove the appropriate module to access the internal electronic components.

To replace the face panel, follow the previous steps in reverse order.

Note: When replacing the face panel, it may be slightly wavy and not slide neatly down into
the groove. If the face panel is not easily reinserted, then start at one end of the display and
gently press your hand against the bottom edge of face panel to slide it into the bottom
support groove.

RS-422 Loop-Back Test (Indoor/Outdoor Displays)

All indoor displays and some outdoor displays (AE-3010, AF-3010, AF-3020, and X-1000) use
RJ11 plugs or connectors. In those cases, a “Network Cable Tester” is provided to conduct
the test.

The network cable tester is used to test for two things:

• verify that a flipped RJ11 cable is being used.

• verify that a good connection is made from a computer or signal converter.

The use of a flipped (reversed) or straight cable can be determined visually. Use the figures
below as a guide, or use the Network Cable Tester box for assistance.

Figure 26: Flipped Cable (Reversed)

Figure 27: Straight Cable

1. Plug one end of the flipped cable into the output from the computer or signal

converter.

2. Plug one end of the flipped cable into J2 (Loopback Connector) on the network cable

tester box.

3. When both ends are

connected, perform the loop­back test using the Venus 1500
software as described in
Section 1.4.
