System Features
The Horizon Signal SQ2 PTS 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 (Communication must be set to Radio to
achieve this). Systems can include up to 14 controllers or phases of traffic. Multiple controllers can be
grouped into the same traffic 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 SQ2 console box:
1. Enhanced Operation - Utilizes all features of the MS 2.0 Controller. Each PTS must have a MS 2.0
controller installed. To activate Enhanced Mode, power on the controller with the Operation Selector
switch in the upward position.
2. Compatibility Operation - Allows MS 2.0 Controllers to work in conjunction 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 Operation Selector switch in the right position.
The controller is programmed using the PTS Programmer hand-held module. The PTS Programmer plugs
into the face of
the controller via the 7-pin receptacle indicated above.
The Rotary Switch can be used to quickly switch between Automatic, Manual, and Flashing operations. In
Enhanced Operation turn the Rotary Switch of any controller in the system to select the desired setting, and
all other signals in the system will enter that mode. In Compatibility Operation only the Master controller’s
Rotary Switch will select the desired setting for all other signals in the system. Before powering up the
controller make sure the Rotary Switch is in the “Automatic”, or “Lamp Off” position only.
