1 Introduction
This manual outlines specications, operation, and troubleshooting for Daktronics TI-2025
and TI-2026 LED segment timer displays. For additional information regarding the
safety, installation, operation, or service of these displays, refer to Section 4: Daktronics
Exchange and Repair & Return Programs (p�7). This manual is not specic to a
particular installation. Project-specic information takes precedence over any other
general information found in this manual.
Important Safeguards
• Read and understand all instructions before rst use.
• Do not let the power cord touch hot surfaces or hang over the edge of a table, which
could damage or cut the cord�
• If an extension cord is necessary, use a three-pronged polarized cord� Arrange the
cord with care so that no one will trip over or pull it out� Inspect the extension cord
thoroughly and verify its compliance with the local electric codes before using�
• Never yank the power cord to pull the plug from the outlet� Grasp the plug and pull to
disconnect�
• Toggle the power switch to “OFF” when not in use or when servicing�
• Disconnect power to the display before servicing power supplies to avoid electrical
shock� Power supplies run on high voltage and may cause physical injury if touched
while powered�
• Do not modify the structure or attach any panels or coverings to the display without
the express written consent of Daktronics�
• Do not disassemble control equipment or electronic controls of the display; failure to
follow this safeguard will make the warranty null and void�
• Do not drop the control equipment or allow it to get wet�
Specications Label
Power specications as well as serial and model number information can be found on an
ID label on the display, similar to the one shown in Figure 1.
Please have the assembly number, model number, and the date manufactured on hand
when calling Daktronics customer service to ensure the request is serviced as quickly as
possible. Knowing the facility name and/or job number will also be helpful.

Daktronics Nomenclature
Most display components have a white label that lists the part
number (Figure 3). Part numbers will also appear on certain drawings.
If a component is not found in the Replacement Parts (p�6), use
the label to order a replacement. Refer to Section 4: Daktronics
Exchange and Repair & Return Programs (p�7) if replacing or
repairing any display component.

Display Controllers
The TI-2025 and TI-2026 timers are designed for use with the All Sport®100 handheld
control console and may also be controlled via the wireless, battery-powered RC-50
controller. The controllers use keyboard overlays (sport inserts) to control multiple sports.
Refer to the following manual for operating instructions:
• All Sport 100 Series Control Console Operation Manual (ED-13432)
The control console manual is available online at www.daktronics.com/manuals.

Mechanical Installation
The timing displays in this manual are portable and are equipped with a handle on the
top for easy transport.
Note: The handles are designed for carrying only and are not to be used as a
temporary hanger or for permanent mounting.
Power & Signal
Reference Drawings:
System Riser: TI-2025 Segment Timer................................................................. DWG-274283
The displays receive power through a 120 VAC power cord. The power cord plugs into a
standard three-pronged outlet. Flip the switch on the side of the display to power it on.
The display will remain blank until it receives signal from a controller.
Signal is provided in one of two ways: 1) via a 9-pin serial to 4-pin XLR cable (Daktronics
part number 0A-1196-0095) connected between the J31 signal input on the side of the
display and the jack on top of the All Sport 100 console, or 2) via radio transmission from
the RC-50 controller to the built in antenna. Refer to DWG-274283 in Appendix A.
Note: Before using the RC-50, the All Sport 100 must rst be connected to the timer in
order to set the practice values as described in the All Sport 100 Control Console
Operations Manual (ED-13432). Then the RC-50 can be used to run the practice
from anywhere on the eld without being constrained by control cable.
Extension XLR control cables are available from Daktronics.

Disconnect power before doing any repair or maintenance work on the display�
Permit only qualied service personnel to access internal display electronics.
Disconnect power when not using the display�
Troubleshooting Table
The table below lists potential problems with the display and indicates possible
causes and corrective actions. This list does not include every symptom that may be
encountered, but it does present several of the most common situations that may occur.
Problem Possible Cause Solution/Items to Check
Display does not light,
and console does not
work
No power to the display Flip power switch ON.
Check that the display has 120 VAC power.
No power to console
Ensure the console is plugged into the J31
jack.
Exchange the console with a working one,
and enter the correct sport code to test.
Replace if necessary.
Display digits do not
light, but console works
No wired signal from
control console
Check that the display is receiving 120 VAC
or battery power.
No radio signal from
control console
Check the receiver (display) and
transmitter (console) radio settings.
Move the console 20–30' (6–9 m) from
the display and test again. Verify that the
display antenna is securely tightened and
in a vertical position.
Replace the radio receiver.
Display digits light, but
not in the correct order
Incorrect sport code
Ensure the correct sport code is being used
for the display model. Refer to the All Sport
100 operation manual (ED-13432).
Incorrect driver address Check that the display driver is set to the
correct address.
Digits light, console
works, but nothing
displays
No wired signal from
control console (see solution above)
No radio signal from
control console (see solution above)
Display works, but some
LEDs always stay on Bad digit
Exchange the digit with a working one
of the same part # to verify the problem.
Replace if necessary. See Replacing Digits
(p�5).
Display works, but some
LEDs do not light or they
blink
Bad connection
Verify the connector on the back of the
digit circuit board is secure. See Replacing
Digits (p�5).
Bad digit (see solution above)
Display works, but some
digits do not light

Component Locations & Access
Reference Drawing:

Component Location; TI-2025/2026, Segment Timer ..................................... DWG-278310
DWG-278310 shows front, back, and side views of the display along with the location of
vital components and the location of the hardware used to attach those components.
To gain access to the internal components of the display, simply remove the screws
securing the front or rear panels. DWG-274184 illustrates the schematic diagram of the
power and signal input wiring.
Replacing Digits
LEDs are embedded in a printed circuit board (PCB) that is mounted to the back of
the timer’s face panel, as shown in Figure 4. Newer weather-sealed digits consist of a
digit circuit board mounted to a black polycarbonate tray and encased in protective
gel, as shown in Figure 5. Do not attempt to remove individual LEDs. In the case of a
malfunctioning LED or digit segment, replace the entire digit circuit board.
To replace a digit:
1� Open the back panel as described in Component Locations & Access (p�5).
2� Disconnect the plug from the back of the digit by squeezing together the locking
tabs and pulling the connector free.
3� Use a 9/32" nut driver to remove the nuts securing the digit to the inside of the panel,
and then lift the digit off the studs.
4� Position a new digit over the studs. Make sure the rubber side of the rubber-backed
spacers are facing the digit circuit board before tightening the nuts. Weather-sealed
digits do not require these spacers.
5� Reconnect the plug to the back of the digit. This is a keyed connector and will attach
in one way only. Do not force the connection.
6� Close and secure the back panel, then power up and test the display to verify the
issue has been resolved.

Adjusting the Horn Volume
The horn volume is set at its maximum level at the factory. If the horn is too loud, reduce
its volume by adjusting the set screw mounted in the front of the horn. A plastic tip on the
screw touches the horn's diaphragm, reducing the volume. Turn the screw clockwise and
test the volume by operating the horn from the scoreboard control console. Continue
adjusting and testing until the desired volume level is obtained.

The following table contains display components that may require replacement. Many of
the other components will have attached part number labels.
