1 Introduction
This manual explains the installation and maintenance of Daktronics TI-2022 portable
timing display. For additional information regarding safety, installation, operation, or
service, refer to the telephone numbers listed in Section 6: Daktronics Exchange and
Repair & Return Programs (p�16). This manual is not specic to a particular installation.
Project-specic information takes precedence over general information found in this
manual.
Important Safety Instructions
• Read and understand all instructions before using the display.
• Do not drop the device or immerse it in water.
• This device may be used outdoors temporarily, but it is not to be permanently
mounted outdoors or left in wet weather.
• This device shall not be exposed to dripping or splashing, and no objects lled with
liquid shall be placed upon it.
WARNING! To reduce the risk of re or electric shock, do not expose this device to rain
or moisture.
• Operate the device with the built-in rechargeable battery. A completely charged
battery will provide at least 10 hours of operation. Use 120 V power only when the
battery’s power is low.
CAUTION! DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY REPLACED.
REPLACE ONLY WITH THE SAME OR EQUIVALENT TYPE.
WARNING! Do not expose batteries to excessive heat, such as direct sunlight or open
re.
• Do not run the display’s battery dead. Charge it for 24 hours before putting it away.
• 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.
• Before using an extension cord, inspect the cable thoroughly and verify its
compliance with the local electric codes.
• Always turn off and unplug the control equipment when it is not in use.
• Never yank the power cord to pull the plug from the outlet. Grasp the plug and pull
to disconnect.
• To avoid electrical shock, do not disassemble the control equipment or the driver
modules. Incorrect reassembly can cause electric shock and faulty operation or
permanent damage to the circuits.
WARNING! To prevent injury, the display must be securely attached to a wall in
accordance with installation instructions.

Display Overview
The TI-2022 is a portable timing system with 9 programmable functions. Though external
power and signal can be applied, the control and power systems are entirely self-
contained. Refer to Section 4: Controls & Timing Functions (p�10) for descriptions of the
TI-2022 control capabilities.
Manufactured in two models, the outdoor version of the timing display is designated as
TI-2022-11, while the indoor unit is designated TI-2022-13.
The timing display is powered by 12 V batteries. Detachable power cord/transformer
assemblies also permit operation of the TI-2022 with 120 or 240 VAC. The unit draws 1
Amp of power. The enclosed batteries (two in the outdoor model and one in the indoor
model) are rechargeable and have a built-in charger.
Product Safety Approval
Both models of the TI-2022 are ETL-listed and tested to CSA standards for indoor use.
Contact Daktronics with any questions regarding the testing procedures.

2 Mechanical Installation
This section describes the mounting details of the TI-2022. Use this section when mounting
a display to a wall or on the tripod kit. Other mounting methods can be used, but
Daktronics engineers do not recommend those not documented here. Daktronics is not
responsible for mounting the display.
Note: Daktronics assumes no liability for any installation derived from the information
provided in this manual or installations designed and installed by others.
Wall Mounting
The TI-2022 mounts to a wall using an optional mounting bracket (Daktronics part #
0M-173125). This bracket then attaches to two wall anchors. A qualied engineer must
specify the anchor type according to national and local building codes.
Note: Do not attempt to permanently suspend the TI-2022 by its carrying handle.
Also, do not permanently mount outdoor displays or leave in wet weather.
Before beginning installation, place the bracket against the mounting surface, level it,
and then mark the surface through the anchor holes on the bracket with a marker or
heavy pencil. Drill holes in the wall and install anchors at the marked locations. Minimum
steel anchor size is 3/16" diameter (4.7 mm).
Note: Due to the variety of wall materials used in sports facilities, Daktronics cannot
anticipate every user’s installation needs or provide mounting hardware suitable
for every installation. Choose a method of installation that will safely support the
display’s weight.
Refer to Figure 4 for display mounting instructions:
Wall Mounting Bracket
(0M-173125)
1. Mount the bracket to
the wall.
2. Loosen 4 screws on
sides of display, slip
them into slots on
bracket, and re-tighten.

Tripod Mounting
Mounting the display to a tripod requires the optional tripod mounting kit (Daktronics part
# 0A-1153-0325). A camera tripod is not sturdy enough to safely support the display and
will not attach to the display or adapter plate. An appropriate “speaker stand” tripod is
available from Daktronics (part # A-1580).
Refer to Figure 5 for instructions on preparing the display for mounting:
1. Remove rubber bumpers
from bottom of display.
2. Push in and discard 2
bottom knockouts.
3. Attach tripod adapter plate
using bumpers and screws.
4. Install knob, nut, and washer
on the tripod adaptor.
5. Attach tripod bracket to adaptor
plate using O-rings and T-bolts.

Power
The TI-2022 contains internal batteries for power but can receive external power through
a detachable transformer cord (Figure 6).

240 VAC
Power Supply Kit:
120 VAC (0A-1240-0071)

12 V IN
Figure 6: Transformer Connection
The primary purpose of the transformer is to charge the internal battery, but the display
can still be operated while the battery is charging. The transformer and cord can remain
plugged into the power source indenitely with no damage to the timer or its battery.
The indoor version (TI-2022-13) has one battery, while the outdoor version (TI-2022-11)
has two batteries. On a full charge, each battery should last approximately 10 hours
before recharge is necessary. To recharge the system, simply plug the power cable into
a grounded power receptacle. The recharging unit will not overcharge the batteries.
Indicator lights on the side control panel show when the unit is charging and when it is
fully charged (refer to Figure 11).
Auto Off
The TI-2022 features an Auto Off function, which will automatically turn the unit off in
response to two conditions:
1� Idle Timeout – If the display is not plugged into a transformer, and not in program
8 or 9 (time of day), and has been idle for 1 hour (not counting, no switch activity,
no signal input), the display will sound the horn and ash the digits 10 times before
turning itself off. Pressing any switch will reset the one hour timer.
2� Low Battery – This feature prevents the TI-2022 from running its battery completely
dead and damaging the battery. When the battery has dropped below a minimum
level, the unit will begin sounding the horn once per second as a warning. If the unit is
not plugged into the transformer for recharging within about one minute, the unit will
automatically turn off.
To turn the TI-2022 back on after an Auto Off has occurred, turn the power switch off,
wait a few minutes, and then turn it back on. In the case of a low battery, be sure to plug
the display into a charger before continuing use.
