System Features®
The Horizon Signal system is capable of three communication types:
• Radio - Wireless communication between all controllers in the system.
• Cable - Wired communication between all controllers in the system.
• Quartz - Synchronized timing of all controllers in the system via quartz clocks. Controllers do not communicate
in this mode. NOT RECOMMENDED.
• A system can also utilize a mixture of radio and cable connections.
Systems can include up to 14 controllers or phases of traic. Multiple controllers can be grouped into the same traic
phase.
Multi-Signal 2.0 Controller
The Multi-Signal 2.0 Controller is capable of two Operation modes, changeable via the Operation Selector Switch inside the
SQ3TS control cabinet:
1. Enhanced Operation - Utilizes all features of the MS 2.0 Controller. Each signal unit must have a MS 2.0 controller
installed. To activate Enhanced Mode, power on the controller with the Mode Selector in the upward position.
2. Compatibility Operation - Allows MS 2.0 Controllers to work in conjunciton with MS 1.0 controllers. See Page 21 for
more information on how to enable this mode. To activate Compatibility Mode, power on the controller with the Mode
Selector in the right position.
The controller is programmed using the PTS Programmer handheld module. The programmer plugs into the face of the
controller via the 7-pin recept indicated below.
The Rotary Switch can be used to quickly switch between Automatic, Manual, and Flashing operation. Turn the dial to select
the desired setting, and al lother signals in the system will enter that mode. The dial only has to be set on one controller.
There is no need to set the dials to the same Mode on all trailers.

Assigning Controller Identities
Before a program can be entered, all of the controllers in the system must be communicating. To accomplish this, each
controller is given an identity. Additionally, when using wireless communication, each radio must be assigned a “Master” or
“Slave” designation as well as an operating channel. Cable can also be used to link the signals together.
1. To begin, power the Controller on with the PTS Programmer plugged in. You will be presented
with the initial startup screen which displays the soware version number.
2. You will then be presented with the “New System” screen. By answering “No,” no changes are
made to the controller’s identity. If you would like ot make changes, use the arrow keys to
navigate the menu, and the plus/minus keys to change the values.
Connection Communication method. Choose from Radio, Cable, or
Quartz (no communication).
Amount of Controllers Total number of controllers in the signal system

3. Repeat this process on each controller in your system. Remember that each controller must
have a dierent Controller Number, but the same total “Amount of Controllers”. These settings
only have to be congured once, unless you are changing the number of lights in your system.

Conguring the Radio
Signal systems using radio communication require one Master radio which can relay program information to all other remote
radios of the system. There are 14 channels that can be used for communication. To congure radio settings, choose
“Congure Radio” from the Main Menu.
1. Use the Arrow keys to select the Radio Type. Each system can only have one Master.
All others get set to Slaves.
2. Set the Channel. All signals (Master and all Slaves) must be on the same channel.
3. Set the Baudrate. For Enhanced Mode (Multi-Signal 2.0 systems), the baudrate should
be 57600. For Compatibility Mode (using Multi-Signal 1 controllers), the Baudrate
must be set to 19200.
4. On the DataLink SRM6230 Radio, press the “Reset/Cong” button. The LED labeled
“M2” will illuminate.
5. On the PTS Programmer, choose “Send” to apply the new radio conguration.
Note: The PTS programmer can read conguration settings from a radio using the “Read” function. This will help to identify
existing network settings when conguring a system.

Main Menu
The Main Menu can be accessed at any time by pressing the “M” button on the Programmer. By using the Up and Down keys,
the user can scroll through the following menu options:

Congure Radio Set radio network parameters
Basic Programming
Programs can be edited or changed at any time while the Horizon Signal system is running. By plugging in the
Programmer, the user can create new programs without any eect on the current program. A new program that is
created will be loaded during the next Red Clearance time, and will be undetectable by motorists.
The Programmer has several program templates for you to choose from. These simple templates represent the most
common types of workzones. To pick the correct template, you will need to know how many phases of traic will be in your
workzone and how many Horizon controllers are in the system. When necessary, basic programs will automatically group
Lights numerically based on their controller identities.
For more advanced programming, or programs that do not fall into any of the templates, SPECIAL programming should be
used.
1. Select the appropriate rogramming type and press E.
2. The speed of the work zone gets entered rst, followed by the distance. The
programmer uses these values to calculate a recommended All Red interval.
This interval can still be adjusted using the Plus and Minus buttons.

3. Set the green times for Phase 1. The rst number on the screen is the base
green. This is the minimum amount of green time a given phase will allow
without detection. The second number is the extension time. The extension will
only be applied if the system is using some form of vehicle detection. If you are
not using detection, the extension will be ignored. Base green plus extension
equlas your maximum green time.
When set to “Yes,” Rest in Red means that the given phase will only go green in the
event of a vehicle detection. When set to “No,” the signal will cycle as normally.
4. Set the green times for Phase 2. These values can dier from those set for Phase
1.
5. Quartz substitution allows the signal system to continue to operate following a
communications loss. It utilizes quartz clock timing for synchronization between
signals. Signals are not in communication when this mode is enabled.
6. Your program can be given a custon name to help identify it. Use the Plus and
Minus buttons to change each character, and press E to advance the cursor.
7. Finally, the Programmer gives you the option to save the program you created.
While it is not a requirement, it may be helpful in the future to have a stored copy
of the program for future use/edits.

Special Programming
Special Programs allow for more control than basic programs, allowing the user to adjust all settings and create custom
signal groups for more advanced aplications. To create a special program, choose Programming from the Main Menu, and
select “SPECIAL.”
1. Start by setting the number of group (phases of traic). For a typical lane closure
project, with an SQ3 signal on either end of the work zone, there would be two
groups.
2. Settings for Group 1 (Phase 1) get entered rst.
Controllers: The number of controllers in the given phase.
Yellow: Yellow time for the given phase.
Traic Gap: Amount of time between vehicles that the controller will
hold a detection.
Error: Flash pattern in the event of an error.
Flash: Flash pattern in a user-requested ash mode.
3. Congure the same settings for Phase 2, and each subsequent phase in your
system.
4. The signal Controller can calculate recommended Red times based on speed
and distance. Enter the distance (from stop bar to stop bar) between each signal,
and the anticipated average speed of vehicles traveling through the work area.
These values will determine the “All red” value that is displayed below. Using
the arrow keys, you can still navigate down and change the All Red interval as
desired.

5. Set the number of programs. Up to 20 dierent programs can be created, each
with diernt green times for dierent times of day / day of week. If you do not
wish to change timings based on time or day, keep this value at 1.
6. Green times for Phase 1 get entered next. The rst number, labeled “Green,” is
the minimum green time. This is the guaranteed amount of time the given phase
will go green per cycle.
The 2nd number, labeled “Extension,” is the additional time this phase will go
green, if detections are active due to traic demands. The minumum green plus
the extension equals the maximum possible green time. Note: Extension will
drop prior to the complete interval if the traic gap value from step 2 is met.
7. Enter the Green times for Phase 2, and each subsequent phase in your system.
8. Enter the number of times you will switch between programs. If you only chose to
create 1 program in Step 5, this number must be 0. If you have created multiple
programs, you can choose up to 30 switch times to move between each program.

9. Enter program parameters.
Max Red: If a signal has rested in red for this amount of time, a call will be
placed to force a cycle on that phase.
Min Red: Minimum red time between green indications on the same phase.
This option prevents very short red times in the event of a
detection on the phase that just ran.
Min Green: Minumum green time, specically when in Manual mode.
Timeout: Communication timeout prior to fault for radio systems.
Red manual: When enabled, red time may be shortened by the operator in
manual mode. When disabled, programmed red times apply.
Quartz sub: When enabled, systhem will revert to quartz timing mode in the
event of a radio communication interruption.
10. Give your program a name, and choose your Save
option.
11. Finally, you can choose to upload and run the
program immediately. If you choose No, the
program is stored in memory, but not uploaded.

System Options
To change these settings, choose System Options from the Main Menu.
• Language sets the micro-terminal language.
• Signal sets units of distance and speed to the appropriate country (USA or Canada - CND).
• Red manual allows the user to manually handle the system with no regard for programmed
Red clearance time. When the option is disabled (set to “No”), Red clearance time is
automatically added between opposing greens when manually handling.
• Timeout refers to the amount of time the controller will tolerate a break in radio
communication. Note that the higher this number is, the longer it will take the system to fail
in the event of a communication loss. The default Horizon value is 5.0 seconds
• Quartz Sub is an option that allows the system to continue operating once radio
communication has been lost. If communication is broken for longer than the Timeout
value, the controller can revert to Quartz mode to continue operating. By default, this
option is set to “Disabled.” There are four other options to choose from in the event of lost
communication:
• Enabled - Normal operation during green intervals, although extension times are
disregarded.
• Error - Instead of a green indication, the programmed Error mode is displayed during
green intervals.
• Preset - Uses the Quartz Substitution setting selected during programming.
• Lamps O - Instead of a green indication, lamps go dark during green intervals.
When the system is running in Quartz Substitution mode, extended green times will be
disabled due to the loss of communication. All green times will equal the base green time
plus half the extension time. If communication is reestablished, the program will run as
normal. Once activated, the system will run a minimum of 2 cycles before returning to radio
mode (once communication has ben re-established).
• Error is the mode that this particular controller will enter in the even of a failure when
running a program. Flash Red, Flash Yellow, Solid Red, and Lamp O are available. Flash
Red is the default setting.
• Flash is the indication that will be displayed when the user manually activates Flash Mode
via the micro-terminal when running a program. Flash Red is the default. NOTE: Using
SPECIAL programming, each phase can be set to a dierent Flash Mode to allow main traic
to ow while side streets must stop.
• Password By setting a password,the user can lock the active program, allowing edits to
be made only aer the correct password has been entered. If the password is forgotten,
please contact Horizon Signal at 800-852-8796.
NOTE: If any of these settings are changed, they will not take eect until a new program is loaded.

System Mode
The mode function of the micro-terminal is used to change between signal operation modes. This menu can also be
accessed by simply pressing “E” from the home screen. Once inside this menu, the user can scroll through the various
operational modes by using the Up and Down Arrow buttons and pressing “E” to select and enter that mode. When a
mode is selected, it will not change until the next programmed red clearance interval has expired.
Runs the currently loaded program.
Signals are operated manually via the micro-terminal. User cannot override red
clearance times.
Signals will operate in the Flash mode selected in the System. Options menu (Red
Flash or Yellow Flash). SPECIAL programs allow for override of this setting within
the program.
Signal indications will go dark and no longer be displayed. Program is not deleted.
All signals will go to a solid red indication and remain in this state until the mode
is changed.
All signals will go to a ashing red indication and remain in this state until the
mode is changed.
All signals will go to a ashing yellow indication and remain in this state until the
mode is changed.
The current program is stopped and erased. Signals will go to Flash mode. A new
program must be created or loaded from memory before signals can operate in
Automatic mode again.
