1)How the Trailer Tracks Service Works
Introduction
The Trailer Tracks service is the Omnitracs wireless system for identifying and locating trailers
for the trucking industry. This service provides cost-effective status monitoring and
management of trailers.
The TT150 system sends status information over-the-air (OTA) to the customer using cellular
functionality. The Trailer Tracks service is a comprehensive, end-to-end trailer identification and
location system, consisting of rugged mobile hardware, reliable network services, robust host
software, and extensive data integration capabilities.
Note: Trailer Tracks service refers to the wireless service that locates trailers. TT150 system
refers to the complete hardware system for the Omnitracs Trailer Tracks 150 service.
Trailer Tracks Service Network Description
The Trailer Tracks service consists of these network components:
Component
Description
Network Operations
Center (NOC)
This facility is responsible for processing and managing the data
traffic between the customer and the trailer. The NOC is located
in Las Vegas, NV.
Customer
The customer’s computer connects with the NOC in order to
receive information from the TT150 system.
Global Positioning
System (GPS)
GPS is a constellation of 24 strategically placed satellites. Signals
from the satellites determine the trailer’s location, which is then
reported to the NOC by the TT150 system.
Cellular Network
The TT150 system uses an existing cellular network to connect.
Trailer Tracks Web
Portal
This allows customers to receive information, request trailer
location information, and perform other functions. The user
interface can be accessed through the Omnitracs Services Portal
or for machine to machine interface, the data can be accessed
via web services integration.
The following illustration shows the interaction between the TT150 system network
components. The TT150 system sends information to the Omnitracs NOC through the cellular
network provider’s gateway. The gateway center sends the information via secure data lines to

80-J7616-1 Rev. C
MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION
8
the NOC. After the NOC receives the information, it sends the information to the Trailer Tracks
Web Portal. The GPS satellite constellation is used for location determination.
What is the Trailer Tracks Service?
The Trailer Tracks service is networking technology and hardware components installed on a
customer’s trailer. The hardware works to send information to customers over a cellular network
and also computes trailer location information using GPS technology.
The GPS and Cellular Network Systems
The TT150 system uses GPS to locate the trailer and a cellular network to deliver
information about the trailer to the customer.
The Global Positioning System
The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a
constellation of satellites and ground stations. GPS uses the satellites as reference points to
calculate positions accurate within a few meters.
How the TT150 System Uses GPS
Signals received from at least four GPS satellites determine the TT150 system terminal’s
(i.e., trailer’s) location. The GPS receiver resides inside the TT150 system terminal to
determine the trailer’s position. The GPS receiver calculates the trailer’s location based on
the time that signals are received from the various satellites. The trailer’s location is sent
each time it communicates and is then available on the Trailer Tracks Web Portal.
The location data is retrieved automatically at regular intervals or can be requested at any
time.
The Terrestrial Wireless Network
The TT150 system uses digital technology to track customers’ trailers over a cellular
network. The TT150 terminal consist of a microprocessor, a wireless modem module, data
storage, antenna, and rechargeable battery.

2)TT150 System Component Overview
TT150 Components
TT150 Terminal
TT150 terminal with microprocessor, cellular modem, rechargeable internal battery pack,
cellular antenna, and GPS antenna. Attached to the terminal is a cable for recharging the
TT150 battery pack when the trailer is connected to a tractor.
The terminal is designed according to industry environmental specifications. The system
allows over-the-air (OTA) reprogramming of the terminal’s on-board firmware.
The TT150 terminal also has two LEDs for verifying cellular coverage and a GPS fix when
active.
The trailer operator (truck driver, loader, or unloader) does not need to access the terminal.
It should be mounted in a safe and secure place on the trailer.
Internal TT150 Battery
Internal to the TT150 terminal housing is a lithium ion rechargeable battery that is used
when the trailer is not connected to external power (i.e. not connected to a tractor). A
fully charged terminal will work for 90 days sending one message/position a day when
not powered. The battery will recharge when power is applied to the 7-way. The battery
is not serviceable.
Note
: The TT150 does not ship fully charged. It is recommended that the battery be
fully charged immediately after it is installed to provide the best messaging experience.
TT150 Power Cable Assembly
The TT150 power cable assembly is permanently attached to the TT150 terminal enclosure.
The power cable assembly contains fuse holders, which are separate from the power cable
assembly to ease routing of the cable assembly and make installation of the TT150 terminal
easier.

3)General Wiring Guidelines
Making Electrical Connections
Approved Omnitracs Electrical Connectors
The only Omnitracs-approved electrical connectors are crimp butt splices and crimp ring
terminals. Omnitracs recommends Nylon insulated, seamless butt connectors with
inspection windows. Heat-shrinkable butt connectors are preferred. When butt splicing
multiple wires on one end of a butt splice and a different number of wires on the other end,
step-down butt splices are recommended.
Warning
: Not following proper wiring guidelines and using improper crimps and butt
splices may cause intermittent connections and may result in unexpected truck down time
or system failure.
Wire Stripping
1. Using a wire stripper, strip approximately 1/4" off the end of an insulated wire.
2.
3. After stripping the wire, verify that the wire is not severed, nicked, or damaged by the
stripping tool. If the wire has been properly stripped, it is ready to be butt spliced. If the
wire has been damaged, restrip the wire.
Butt Splicing
Make sure the size of the butt splice is appropriate for the job. A good butt splice has these
characteristics:
•The ends of the bare wires are visible through an inspection window.
•The ends of the wires “butt” up against the stop.
•The wires are not exposed beyond splice shielding.
•Crimping does not sever or damage the wires or insulation.
1. Insert the stripped wires approximately half way into a butt splice, preferably one with
an inspection window for verifying the wire is in the correct position.

80-J7616-1 Rev. C
MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION
12
2. Repeat this process for the wire on the opposite end of the butt splice. Once a proper
butt splice is confirmed, it is important to properly crimp the butt splice to hold the
connection.
Crimping
•When crimping a butt-spliced wire or cable, be sure the insulated butt splice is crimped
using the insulated position on the crimp tool and not the crimping “tooth” of the tool.
•Crimping butt splices incorrectly can result in a severed wire and a failed wire
connection.
1. Using a crimping tool, crimp the butt splice one end at a time. First, crimp the inside
crimp area where the wire has been stripped. Apply necessary pressure to this inside
area.
2. After crimping the inside of both ends of the butt splice on the “insulated” area of the
crimping tool, next crimp the outside of both ends of the butt splice.

80-J7616-1 Rev. C
MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION
13
3. Verify that the crimps are good and the wires have not been damaged.
4. Do a pull test. Pull on both ends of the wires to ensure a solid butt-spliced connection
exists. The crimped butt splice securely grips the insulated wires.
Strain Relief
If there is sufficient wire available for the Four-Finger Wrap Method:
1. Wrap a wire around four fingers of a hand, one full loop, so that the wire loop is longer
than the wrapped butt splice.
2. Pinch the loop tightly and center it against the wrapped butt splice.
3. Secure the wires together and place 4" tie wraps at the outside ends of the butt splice.
4. Cinch the tie wraps tight and cut them flush to the lock head.

80-J7616-1 Rev. C
MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION
14
5. Firmly tug on the butt-spliced wire connection to make sure the tie wraps do not pull
loose.
If there is NOT sufficient wire available for the Four-Finger Wrap Method:
1. Securely tie wrap the butt spliced wires to existing wires or harnesses in the nearby
vicinity.
Ring Terminals
When making electrical connections, crimp ring terminals onto the ends of the wires to
ensure good contacts. A properly crimped ring terminal has these characteristics:
•The barrel crimping indent is well-formed and properly positioned.
•The insulated wire’s grip impression is well-formed and provides proper support
without crushing the insulation.
•The wire does not move independently of the lug. Firmly tug on the ring terminal to
ensure it does not pull loose.
•The end of the bare wire protrudes through the crimp barrel approximately 0.03 to
0.125" depending on the lug size and crimp tool.
Install the ring terminal on the ground connection using one of the following options:
Grounding Guidelines
Caution
: When establishing a good chassis ground, avoid areas that can be potentially isolated
from ground by a hinge or some welds.
It is extremely important that you create clean, secure, tight, metal-to-metal grounds.

80-J7616-1 Rev. C
MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION
15
If grounding terminals are not available, remove the paint from the surface of the metal
connected to the chassis to make the ground. Make sure the wires are not strained or
vulnerable to damage.
Routing and Protecting Cables
Cable Routing Guidelines
•When routing outside of the vehicle or around sharp edges always use protective
sheathing, such as convoluted tubing or wire loom to protect the cables.
•Use P-clamps and tie-wraps to secure cables and wires.
•If drilling penetrates into an enclosed area, seal all holes to keep moisture out.
•Whenever possible, route cables with any existing vehicle cables.
•When reinstalling plywood sheets, be careful that screws do not penetrate cables.
•Use rubber grommets when cables are routed through holes with sharp edges.
•Use silicone sealant (RTV) around the 7-way where cables enter to prevent water
intrusion.

Survey the Trailer
Survey the trailer and decide where exactly to install the hardware. Ensure the TT150
terminal and cable are not in a location where they are prone to be bumped or damaged
by normal gladhand/connection coupler operation.
Terminal and Cables
Make sure that the TT150 system terminal and cable locations do not hinder normal
operation or maintenance of the trailer. Also if cables are routed internally, make sure the
TT150 system terminal and cables are installed and/or stored safely out of the way of
possible damage by cargo or other factors.
What to Consider Before Installing the System
•Drill holes only when necessary.
•Omnitracs recommends you use existing holes on the trailer for cable routing whenever
possible.
•Use silicone (RTV) sealant when necessary to prevent leakage.
Installation Guidelines
When making installation decisions, consider safety, security, quality and reliability, and
accessibility.
•Use eye protection when using a drill or performing work that poses any hazard to the
eyes.
•Use ear protection in a noisy working area.
•Wear appropriate clothing or uniforms and safety shoes.
•Make sure you know what is behind the area before you drill.
•Make sure ladders and portable scaffolding are in good condition.
•Place ladders in safe positions.
•Install equipment so it will not cause damage to the trailer or hardware over time or will
work loose over time.
•Make sure there are no loose components/cables and no unsecured components.
•Use solid mounting surfaces.
•Install all components in a location where they will not be abused.
•Route all cables away from sharp or abrasive areas where they might become damaged.
•Choose a location where components are safe from tampering.
•Choose a location where future maintenance can be easily serviced.

Typical TT150 Installation Sequence
Trailers and flatbeds often differ from manufacturer to manufacturer. The TT150 system was
designed to work with a variety of trailer types; however, every installation is unique and should
be thoroughly planned out before implementation.
1. Identify the installation location.
2. Mount the unit.
3. Route the power cable and cut as needed to the appropriate length
4. Connect wires to the 7-way.
5. Use the TT150 Field Service Tool (FST) to configure the TT150 and to perform system
verification. The FST is also used to diagnose any problems with the system.

5)Installing the TT150 Terminal
Dry Van Trailers
Overview
The TT150 terminal installs outside the trailer. For dry van trailers, the TT150 terminal is
installed on the trailer’s nose surface. The attached TT150 power cable runs from the TT150
terminal to the 7-way receptacle, which recharges the internal battery when a truck is
connected to the trailer.
Thoroughly evaluate the trailer nose area to determine if the TT150 system can be installed
on the trailer. Determine if rivets or VHB tape will be used to secure the TT150 terminal to
the trailer. Typically, rivets are used for installations on dry van trailers. The trailer should be
free of extensive damage in all installation areas. For specific tools required, refer to Tools
and Supplies Needed for Installation in chapter 4.
The TT150 terminal can be installed high up on the nose of the dry van trailer to reduce the
likelihood of tampering and lessen GPS signal obstruction or it can be installed lower on
the trailer, near the 7-way when not enclosed by metal and does not interfere with
gladhand/hose coupler connection operation. It is recommended to install one terminal in
the desired location and verify operation for both GPS and cellular signal reception before
installing additional units.
Installation
Typically, two rivets are used to secure a TT150 terminal to a dry van trailer. The power
cable connects the TT150 system terminal to the trailer’s electrical power source at the 7-
way receptacle. The power cable is 10 feet long and can be cut as needed depending on
where the TT150 terminal is installed. It may be necessary to drill a hole through the 7-way
housing to provide a route for the cable.

1. On the outside of the trailer, select the location where the TT150 terminal will be
installed/mounted.
2. Use the TT150 terminal as a template for marking the two holes needed for the rivets to
mount the device. Use the holes on the outside of the mounting ears to allow access for
a rivet gun. If rivets are used, the VHB tape should not be used for the installation.
3. Drill the two holes where marked using a 3/16” drill bit.
4. Place a dab of silicone sealant around each hole.
5. Using the appropriate supplied rivets, rivet the TT150 terminal to the trailer.
Note:
Non-duraplate rivets are used for trailer walls with a thickness of .214 to .437 inch,
which is typical dry van panel thickness. Duraplate rivets are used for trailer walls with a
thickness of .35 to .625 inch, which is less common.
6. Check to make sure the TT150 terminal is riveted tightly against the trailer skin and
there is no gap between the back of the terminal and the trailer surface.
7. Route the cable to the 7-way and refer to Chapter 6: Connecting the TT150 to the 7-
Way.
