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.
Figure 4: Wall Mounting Kit Installation

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.

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.

Electrical Installation

Wired Signal Connection
The TI-2022 is designed as a standalone timer with no need for signal cable from control
consoles. However, it is still possible to connect signal in from Daktronics All Sport®scoring
consoles and OmniSport®2000 timing consoles, and signal out to multiple displays. For
signal cable, Daktronics recommends, as a minimum, single-pair, shielded cable, 22
AWG (Daktronics part # W-1077). Two-pair shielded cable (part # W-1614) is preferred.
Wireless Signal Connection
The TI-2022 is capable of being controlled via wireless signal. The wireless radio system
requires a Daktronics All Sport®scoring console or OmniSport®2000 timing console
equipped with radio transmitter as well as a radio receiver mounted inside the display.
The optional radio receiver is installed on the left side of the display cabinet (as viewed
from the front).
1� Power off the display.
2� Turn the display around so that you are looking at the rear.
3� Using a Phillips screwdriver, remove the 10 outer screws to separate the front and rear
panels of the display.
4� CAREFULLY lay the front panel at to expose the internal components.
5� Connect the 6-pin power/signal cable from the radio receiver unit (A) into the mating
6-pin radio adapter cable (B) connected to the J2 RADIO JACK on the left side of the
driver printed circuit board (PCB). Refer to Figure 7.

Radio Settings
With a radio receiver installed in the display, watch for the radio Broadcast settings (“b1”)
and Channel settings (“C1”) during the Power-On Self Test (POST).
These values must match the settings in the control console:
If the radio receiver channel and broadcast settings match those set in the console but
the console does not control the display, there may be radio interference. This can occur
when a nearby display also uses radio control. In this case, change the settings of the
wireless radio receiver inside the display and in the console as described in the radio
control manuals.

Program Operations
1� Count Up with Pushbuttons� This program counts up from 0 to a programmed time
and sounds the horn. Operators can program the time from 0 to 99:59 (mn:sc) using
the switches on the side of the display. If the time is set to 0:00, the display will count
up to 59:59, roll over to 0:00, and continue counting.
In this program, the time can be started and stopped using the switches on the side,
or external, normally open contacts. If a stop input is received within 9.99 seconds
before the start, the display will show a -XX.X time on the digits for 10 seconds
following the start and then will resume counting. While the display is counting, a start
input will hold the elapsed time for 10 seconds and then go back to the running time.
2� Count Up with Photocells. This program counts up from 0 to a programmed time and
sounds the horn. The operator can program the time from 0 to 99:59 (mn:sc) using the
switches on the side of the display. If the time is set to 0:00, the display will count up to
59:59, roll over to 0:00, and continue counting.
In this program, the start and stop inputs are typically external, normally closed
contacts. If the stop input is received within 9.99 seconds before the start, the display
will show a -X.XX time on the digits for 10 seconds following the start and then will
resume counting. While the display is counting, a start input will hold the elapsed time
for 10 seconds and then go back to the running time.
3� Agility Timer. This program is used to time events with a unique start and stop. These
events typically last less than 99.99 seconds; if the timer reaches 99.99, it will roll over
to 0.00 and continue counting. Unlike programs 1 and 2, once the timer is stopped, a
start input will not cause it to begin counting again.
4� Game Clock. This program counts down to 0 from a programmed time and sounds a
horn. The operator can program the time using the switches on the side of the display
from 0 to 99:59 (mn:sc). If the time is set to 0:00, the display will count down to 0:00,
roll over to 59:59, and continue counting down.
5� Qualifying Timer. This program utilizes one photocell plugged into the START input to
qualify oval track. Timing range is from 0 to 99.99 seconds.
Pressing the <RESET> switch will set the display to 0.0 seconds and clear the best time.
With a photocell connected to the START input, the rst car that passes through the
photocell will start the clock counting. The timer will then ignore the photocell for 3
seconds to ensure that the car has completely passed through the Start/Finish line.

Controls & Timing Functions
12
The next time the car passes through the photocell, the clock will display the current
lap time for 10 seconds. Again, the clock will ignore the photocell for 3 seconds to
ensure that the car has passed completely through the Start/Finish line. The internal
clock also restarts at 0 and counts the time for the next lap. After the previous lap
has displayed for 10 seconds, the digits will show the new lap time. The next time a
car passes through the photocells, the time will freeze for 10 seconds and repeat the
cycle. This may be repeated for however many qualifying laps that a car will make.
When the car has completed its qualifying run, press the <STOP> switch on the side
of the display, and the best lap time will be displayed on the digits. The qualifying
sequence for the next driver will start the next time a car passes through the
photocells.
6� Flop Clock. This mode counts up in one-second increments to 9999, rolls over to 0,
and continues counting.
7� Lap Counter. This program uses the <START> switch to increment the display by one
from 1 to 9999. The <STOP> switch decrements the count by one.
8� 12-Hour Time of Day. This program displays the time of day in 12-hour format.
9� 24-Hour Time of Day. This program displays the time of day in 24-hour format.
Note: An All Sport control console or an OmniSport timing console can be connected
to the TI-2022 to control it, but the TI-2022 system is then limited to being an output
device rather than the self-contained timing system for which it was designed.

Exchange Program
The Daktronics Exchange Program is a service for quickly replacing key components
in need of repair. If a component fails, Daktronics sends a replacement part to the
customer who, in turn, returns the failed component to Daktronics. This decreases
equipment downtime. Customers who follow the program guidelines explained below
will receive this service.
