3 Description
This section provides a general description of the
Opticom™ GPS system and a detailed description
of the intersection equipment.
Opticom GPS System
The Opticom GPS system assists authorized
priority vehicles through signalized
intersections by providing temporary right-ofway through the use of common traffic
controller functions.
The Opticom GPS system consists of the
following matched components:
Vehicle Equipment —
•
Radio/GPS unit containing a GPS receiver and
a 2.4 GHz transceiver
•
Radio/GPS antenna
•
Vehicle Control unit
Intersection Equipment —
•
A traffic pole mounted Radio/GPS unit
containing a GPS receiver with antenna and a
2.4 GHz transceiver with antenna (Model
1010)
9
The vehicle equipment is mounted on the
priority vehicle. Its GPS receiver acquirers
position information from the constellation of
GPS satellites. This information is used to
compute the location, speed, and heading of
the vehicle. This information, along with a
priority request and the state of the vehicles
turn signal, is broadcast using the 2.4 GHz
transceiver.
The intersection equipment receives the radio
transmission from the vehicle equipment. The
intersection equipment then compares the
information being received from the vehicle to
the parameters stored in the intersection
equipment’s memory. If the vehicle is heading
toward the intersection in a predefined approach
corridor, is requesting preemption and has met
all other programmed parameters, the
corresponding phase selector output is activated.
This output is connected to the traffic controller
preemption input. When activated, the
controller cycles to grant a green light to the
requesting vehicle or holds the green allowing
the vehicle to pass through the intersection.
The card rack/input file provides the power and
logic wiring for the phase selector, which plugs
directly into a slot in the unit.
•
Or a Traffic Cabinet mounted Radio/GPS unit
containing a GPS receiver and a 2.4 GHz
transceiver (Model 1012)
The auxiliary interface panel provides additional
connection for monitoring green phases and also
provides additional priority control outputs.
•
Radio/GPS antenna (Model 1050)
•
Phase Selector (Model 1000)
•
Card Rack/Input File (Model 1040)
The auxiliary harness can be used to provide
additional connection for monitoring green
phases when the auxiliary interface panel is not
required.
•
Auxiliary Interface Panel (Model 1030)
•
Green Sense Harness (Model 1035)

Intersection Equipment Installation Instructions
3.1 Intersection Equipment
The Opticom™ GPS System intersection
equipment has two styles of Radio/GPS units
available.
The first is the Model 1010, which is a compact,
weather-resistant, Radio/GPS unit containing a
GPS receiver with antenna and a 2.4 GHz
transceiver with antenna. This model is typically
mounted on a traffic pole near the traffic cabinet.
The second is the Model 1012 Radio/GPS unit,
which contains a GPS receiver, a 2.4 GHz
transceiver and a separate Radio/GPS antenna.
This model is mounted in the traffic cabinet with
the antenna mounted on the roof of the cabinet.
Both models of the Radio/GPS unit are connected
to a phase selector via an 11-conductor radio/GPS
cable.
The phase selector can be installed directly into
an input file of a traffic controller equipped with
priority phase selection software. The phase
selector can also be installed directly into virtually
any other traffic controller equipped with priority
phase selection inputs and related software.
When input file space is not available, a card rack
is required. The phase selector is powered by +24
VDC. A power supply in the card rack or an
external power supply provides the +24 VDC.
The phase selector processes the signal from the
radio/GPS unit and activates outputs which are
connected to the preemption inputs on the traffic
controller. There are four channel outputs
accessible on the rear connector of the phase
selector and up to 12 additional channel outputs
accessible on the front of the phase selector.
Each channel output delivers a constant output for
high priority activation, and a pulsed output for
low priority activation. A high priority signal
received on a channel will override any low
priority activation. In certain modes of operation,
outputs may be activated that are dependent on
the state of the requesting vehicle’s turn signal.
Another mode provides separate outputs for high
priority and low priority. The use of an auxiliary
interface panel is required to access these
additional modes and outputs.
This manual describes the installation of the
radio/GPS unit, a card rack (when required), and
installation of a phase selector into either a card
rack or a Type 170 input file.
Figure 3-1 shows the phase selector installation
components including the phase selector, card
rack, input file, auxiliary interface panel, and the
wiring harnesses and cables. The 9-pin harness
connects the card rack to the traffic controller. The
communication cable connects the phase selector
to a PC. Additional communication connections
are available on the auxiliary interface panel. The
auxiliary interface panel cable connects the phase
selector to the auxiliary interface panel. The
auxiliary harness connects green sense inputs to
the phase selector. The radio/GPS cable connects
the phase selector to the intersection radio/GPS
unit. A customer-supplied 24 VDC power cable
connects the phase selector to an external power
supply, which is required when the phase selector
is plugged directly into an input file of a traffic
controller cabinet that does not have 24 VDC on
the edge connector.
NOTE: Illustrations and connections to the
traffic controller may not be exactly as shown
or described in this manual. Refer to the
controller wiring diagram for correct terminal
connections.

This section describes the installation of
intersection equipment. There are two models of
the Radio/GPS unit. See section 5.2.1 for details
on installing the Model 1012 Radio/GPS unit.
The Model 1010 radio/GPS unit should be
oriented such that the cable retainer is facing
an area from which vehicles will NOT be
approaching. See Figure 5-1.
•
Do not paint the Model 1010 radio/GPS unit
cover. Metals or metal oxides in the paint may
interfere with GPS reception and/or radio
reception/transmission.
•
Do not modify the radio/GPS unit circuitry.
There are no user-serviceable parts inside.
5.1 Model 1010 Radio/GPS unit mounting
Location Considerations
Read and understand the following precautionary
paragraphs before starting the installation.
•
The Model 1010 radio/GPS unit should be
mounted in a location that has an
unobstructed view of all approaches out to a
distance of 2500 feet.
•
Blockage of approaches by things such as
bridges, buildings, walkways, and trees should
be avoided.
•
The Model 1010 radio/GPS unit is usually
mounted to the mast arm or span wire pole
nearest the traffic controller cabinet. If an
appropriate mounting location on a mast arm
or span wire pole is not available, you can
mount the unit to a span wire. Try to use a
signal head or sign mount to minimize sway.
•
The Model 1010 radio/GPS unit should be
mounted level and as high as possible. Do
not mount the unit upside down.
•
The Model 1010 radio/GPS unit should have
an unobstructed view of at least 50% of the
sky.
•
The mounting location should be such that
the cable run from the radio/GPS unit to the
phase selector (located in the traffic controller
cabinet) is no more than 250 feet.
•
The radio/GPS cable may be run through
conduit or attached to a messenger wire. The
cable should not be suspended unsupported.
IMPORTANT NOTE
Modifying the radio/GPS unit may seriously
damage the equipment and void the warranty.
Do not attempt to modify the radio/GPS
circuitry in any way. Modifying the radio and/or
antenna in any way may cause the radio to
violate FCC/IC requirements.

5.3 Model 1012 Radio Installation
This section describes how to install the Model
1012 version of the Opticom™ GPS radio.
Important Note:
The Model 1012 radio is designed to be installed
directly inside of the traffic cabinet with the
antenna mounted on the roof of the cabinet.
This style radio should only be installed if it is
determined from a site survey that the location
will not overly degrade GPS reception and or
radio transmission and reception. Since the
antenna is mounted at the height of the top of
the traffic cabinet rather than at the height of the
traffic signals, the antenna’s view of the sky (for
GPS reception) may be less. Also by mounting
the antenna lower, obstacles such as buildings,
trees etc., will likely reduce radio range. If it is
determined by survey of the intersection that
these reductions will still allow the Opticom GPS
system to operate satisfactorily, then the Model
1012 may be installed. If not, it is recommended
that a Model 1010 radio be used.
IMPORTANT NOTE
Modifying the radio/GPS unit may seriously
damage the equipment and void the warranty.
Do not attempt to modify the radio/GPS
circuitry in any way. Modifying the radio and/or
antenna in any way may cause the radio to
violate FCC/IC requirements.
REMARQUE IMPORTANTE
La modification du système radio/GPS risque
d’endommager sérieusement le matériel et d’annuler
la garantie. Ne pas tenter de modifier les circuits du
système radio/GPS de quelque façon que ce soit. En
modifiant le système radio et/ou l’antenne de quelque
façon que ce soit, la radio risque de ne plus répondre
aux exigences de la FCC/IC.
5.3.1 Model 1050 Antenna mounting
NOTE:
1. Do not paint the radio/GPS antenna
cover. Metals or metal oxides in the
paint may interfere with GPS reception
and/or radio reception and transmission.
2. Be sure to capture metal shavings when
drilling a hole in the cabinet.
Antenna mounting factors:
•
The antenna must be mounted on the top
of the cabinet so that the GPS antenna has
a good view of the sky.
•
To minimize possible vandalism, mount it
in a location that is the least visible.
1. Remove the nut and washer from the
Radio/GPS antenna.
2. Drill a 5/8 to 3/4 inch hole in the top of the
cabinet. See Figure 5-7.
3. Route the cables through the hole and replace
the lock washer and nut.
4. Tighten the nut with a 15/16 inch wrench (a
24 mm wrench may be used if a 15/16 inch
wrench is not available).
Note: Do not over tighten the nut or the antenna
may be damaged. 5 ft/lbs is the recommended
torque.
5. Apply silicone RTV (not provided) around the
antenna to provide a good seal with the
antenna’s built-in gasket.

radio/GPS unit location.
2. Coil up any excess cable.
NOTE: When coiling excess cable do not create
any sharp bends in the cable or the cable may be
damaged.
3. Connect the cable labeled GPS to the GPS
connector on the radio/GPS unit. Connect
the other cable to the Radio connector.
Tighten the connectors using a 5/16 inch
wrench (an 8 mm wrench may also be
used).
4. Plug the 15 pin connector of the
radio/GPS cable (black cable) into the P1
connector of the radio/GPS unit and
tighten the screws.
5. Route the cable to the location where the
phase selector will be installed.
6. Skip to Section 5.5.2 for details on
connecting the radio/GPS cable.
NOTE:
1. The connectors are keyed and
cannot be connected to the wrong
connector.
2. To avoid damage to the equipment
always connect the GPS and Radio
connectors before connecting the
radio/GPS cable. Plug the cable into
the phase selector last.
3. The radio/GPS unit is not watertight;
therefore it should be mounted inside
the cabinet compartment.
4. Never operate the equipment with the
antenna cables disconnected or the
equipment may be damaged.

5.4 System Configurations
This section describes two configurations for
installing Opticom™ GPS System Phase Selectors:
Type 170 controller installations and NEMA
controller installations. Determine which
configuration applies to your system, then go to
the section number shown for the installation
instructions.
NOTE: Read through the section for your
configuration and perform the applicable
installation procedures, then go to Section 8 to
check out the installation.
5.4.1 Type 170 Controller Installations
5.5.1 Phase Selector Installation
WARNING
Improper or incomplete programming of the
traffic controller may cause improper
operation of the traffic signals, which may
result in accidents and/or injuries. To avoid
this problem, verify that the operation of
the traffic controller is appropriate for your
needs before, during, and after actuation of
the priority control inputs. Improper
operation of the traffic signals may result in
unsafe driver action.
CA/NY Type 170 controller cabinets (and some
NEMA cabinets) have input files that will accept
one phase selector. Logic wiring is factory
installed in the cabinet for the phase selector.
Power for the phase selector is provided by an
external power supply.
See Section 5.4 for installation of phase selectors
into Type 170 controllers.
5.4.2 NEMA Controller Installations
NEMA controllers with priority control inputs
usually require a card rack. Each phase selector
plugs directly into the card rack. The card rack
wiring harness provides inputs and outputs to the
traffic controller system hardware.
See Section 5.5 for installation of phase selectors
into NEMA controllers.
5.5 Installation — Type 170 Controllers
These instructions include:
•
Installing the phase selector. See Section
5.4.1.
•
Connecting the radio/GPS cable to the phase
selector. See Section 5.4.2.
•
Installing the auxiliary interface panel.
See Section 5.4.3.
•
Wiring for green sense.
See Sections 5.4.4 and 5.4.5.
•
Cabling for remote communication.
See Section 5.4.6.
Two input file slots are dedicated for use by
Opticom GPS System Phase Selectors. These slots
are usually J12 and J13 in the lower input file.
They are pre-wired and have a direct association
with particular priority control inputs to the traffic
controller. Both J12 and J13 supply two priority
control inputs to the traffic controller. Refer to
your cabinet drawings to verify the slots, which
are usually referred to as EVA, EVB, EVC, or EVD.
The outputs from the phase selector are
connected to the preemption inputs of the traffic
controller. Each phase selector output must be
connected to a separate controller preemption
input. Consult the manual for your controller to
determine if the preemption inputs are handled
with the same priority. For some traffic
controllers, preemption inputs one and two are
intended for railroad and draw bridge preemption
and are given precedence over the rest of the
preemption inputs.
Intersection Equipment Installation Instructions
When programming your priority control routines,
it is important to use values that will allow the
traffic controller to respond to a priority control
request as quickly and safely as possible. If the
routines are not programmed to respond quickly
enough, the requesting vehicle may not receive a
green light in time to travel through the
intersection safely.
1. Set the power switch on the front panel of the
phase selector to OFF.
2. Install the phase selector into slot J13 of the
lower input file, making sure it is fully seated.
See Figure 5-11.

1. Strip approximately 3 inches of the outer
jacket from the end of the cable. Be careful
not to cut the wires inside.
2. Strip 1/4 inch of insulation from each wire.
NOTE: It is very important to not strip too much
insulation, which may lead to short circuits; or
too little insulation, which may prevent the wire
from making good contact.
Place each wire into the appropriate terminal in
the 11-pin terminal block and tighten the screw to
secure the wire. The label on the terminal block
shows the color of each wire. Table 5-1 also
shows the terminal block pin number, wire color,
and function of each wire.
The terminal block may be removed from the
phase selector to allow easier connections.

14 Appendix C: Driving a Relay From a Phase Selector
It is possible to drive an electro-mechanical or
solid-state relay from a phase selector output.
However, this application falls outside of the
intended use of the Opticom™ GPS System and
the system was not designed for this application.
Should you do so on your own, it is important to
use a relay that falls within the parameters
described below to prevent damage to the phase
selector. It is recommended that you use a Model
1045 Gate opener card rack which includes a
relay. See Appendix D for details
Figure C-1 is a wiring diagram that shows how
the relay is connected to the phase selector.
Figure C-1. Wiring Diagram
*Numbers 1 – 4 correspond to the numbers in the Recommendations section on the next page.

58
Intersection Equipment Installation Instructions
Recommendations
1. Use a 1N4004 or equivalent diode.
2. Use a 24 VDC relay with a coil impedance of
approximately 1000 ohms. The maximum
amount of current that the phase selector
output is designed for is 50 mA.
The following relay manufactured by IDEC meets
the above listed requirements:
•
Relay: RH1B-UD-DC24V
•
Socket: SH1B-05
This relay contains a diode, so the diode shown in
Figure C-1 is not needed.
This relay is available from Newark Electronics and
other electronics supply houses.
NOTE: For applications with frequent activations,
it is recommended that a solid-state relay be used
in place of an electro-mechanical relay. A load
switch would be another option.
•
Omron G3NA-205B-DC5-24
This relay is available from Digikey
www.digikey.com, (p/n Z165-ND) and other
electronics supply houses.

15 Appendix D Gate opener Card Rack
15.1 Model 1045 Card Rack Installation
The Model 1045 Gate Opener Card rack is
intended to allow an authorized vehicle that is
equipped with Opticom GPS vehicle equipment to
open a gate. Other possible applications are to
allow an authorized vehicle equipped with
Opticom GPS vehicle equipment to activate a
flasher, sign, etc.. The 1045 Gate Opener card rack
is used in conjunction with an Opticom GPS phase
selector and an Opticom GPS radio/GPS unit to
accomplish these tasks.
The Opticom™ GPS System Model 1045 Gate
Opener Card Rack has the following features:
• Integrated Electro-Mechanical Relay compatible
with most Gate Openers.
• Provides dry contact outputs.
• May be used in Normally Open and Normally
Closed applications.

verify that the operation of the gate opener
is appropriate for your needs before, during,
and after actuation of the priority control
inputs. Improper system operation may
result in system/device failure leading to a
delay of the emergency vehicle.
Rear outputs 1 and 2 from the phase selector are
connected to the relay inside the card rack. The
outputs of the relays are then connected to the
terminal on the front of the card rack. These
terminals are intended to be connected to the gate
opener to activate the gate. Consult the manual for
your gate opener to determine the proper
connections. See Figure 15-1 for a typical
mounting location of the Gate Opener Card rack in
a gate opener cabinet.
WARNING
This procedure may expose you to AC voltage
and the risk of electric shock or electrocution.
Turn off the AC mains and use accepted and
recognized safety precautions to avoid
exposure to the risk of electric shock or
electrocution. Electric shock may cause
severe injury or death.
60
