1.3 About the CalAmp Location Messaging Unit-TTU-2830™
The CalAmp Location and Messaging Unit-TTU-2830™ (TTU-2830™) is a mobile device designed for private, commercial, or government vehicles. It is a single-box enclosure containing a processor, GPS receiver, wireless data modem, and a vehicle-rated power supply. The TTU-2830™ also supports inputs and outputs for monitoring and reacting to the vehicular environment and driver actions.
2 System Overview
2.1 Overview
A fleet management system's purpose is to remotely contact a vehicle, determine its location or status, and act upon that information. This can include displaying location on a map, performing address look-ups, providing driving directions, updating ETAs, monitoring status, or dispatching vehicles. These functions depend on the vehicle management application. The CalAmp TTU-2830™ delivers location information when and where it is needed.
A typical fleet management system using a CalAmp device includes:
- A wireless data network
- An TTU-2830™ unit
- Backend mapping and reporting software (e.g., from Actsoft)
2.2 Component Descriptions
2.2.1 Wireless Data Network
The Wireless Data Network acts as the information bridge between Actsoft servers and the TTU-2830™. This network can be cellular, satellite, or local area networks.
2.2.3 Backend Software
Backend software, often provided by Actsoft, parses and presents data from the TTU-2830™. It enables functions such as:
- Displaying location data in various report formats.
- Presenting historical information in report/chart style.
- Requesting location updates from TTU-2830™ units.
3 Hardware Overview
3.1 Location Messaging Unit-TTU-2830™
Sub-assemblies must be sealed in an ESD-safe bag if not fully packaged in their final housing during shipping.
Electrical Over-Stress (EOS)
The GPS receiver can be damaged by RF levels exceeding its maximum input rating, which can occur if a nearby source transmits a high-level RF signal.
Storage and Shipping
To prevent EOS, keep TTU-2830™ GPS Antennas at least four inches away from active TTU-2830™ CELLULAR Antennas or other high-power RF transmitters (over 1 Watt) to avoid potential damage when one unit is transmitting.

3.5 Motion Sensor Input
The TTU-2830™ has an internal motion sensor. It detects motion for at least 30 consecutive seconds and will track at a 5-minute interval for approximately 350 messages when motion is detected.
3.5.1 Power State Input
This input indicates whether the TTU-2830™ is using external power (Low state) or its internal backup battery (High state).
3.5.2 Battery Voltage Critical Input
A built-in low battery threshold of 3500mV is tied to a discreet input. If the battery reaches this limit, a "Low Battery" event is sent to Actsoft systems.
3.5.3 Ignition and Inputs
The TTU-2830™ provides up to 3 external inputs, protected from vehicle transients. They can connect to vehicle level logical inputs from 4V up to 12VDC, with an input impedance of approximately 10kΩ. One input is dedicated to sensing ignition status for power management. The other two inputs can monitor vehicle conditions like cooling unit operation or a driver's "Panic" switch.
The ignition input is pulled to ground through a 10kΩ resistance. Other inputs can be normally High (pulled to +12V via 10kΩ) or Low (pulled to ground via 10kΩ). Input 1 is always biased low; inputs 2-4 are biased high.
Input Wiring Examples
Input Wiring - biased high example: Illustrates connecting a dome light via a door switch to Input 2, and an ignition sense to Input 0. Both inputs have pull-down resistors to ground.
Input Wiring - biased low example: Shows connecting a panic button to Input 1, and an ignition sense to Input 0. Both inputs have pull-down resistors to ground.

4 Installing the LMU
The installation of the LMU and its antennas significantly impacts performance. Installers should be familiar with GPS and cellular device installation and comfortable working in a vehicle environment.
4.1 Preparing for Installation
Ensure all LMU components are received, including:
- The LMU unit
- A power harness
- GPS Antenna (for external devices)
- Comm Antenna (for external devices)
- Optional Components: Input and output cables
4.2 Plan The Installation
Verify Power, Ground and Ignition: Use a multi-meter to check these sources for proper signaling.
Component Placement: Before drilling or running wires, decide on locations for the LMU, antennas, and peripherals. Ensure cables are not bent or constricted and the LMU is protected from direct exposure to elements (sun, heat, rain, moisture).
Warning: Installation violating environmental specifications will void the warranty.
For a trouble-free installation, consider options and make decisions beforehand. Evaluate the vehicle to determine the best installation for:
- Accurate data gathering and simulation of customer usage.
- Ongoing monitoring and maintenance of LMU equipment.
- Preventing accidental or intentional alteration of equipment or cable connections.
The following sections detail considerations for planning your LMU installation.
4.2.1 Size and Placement of LMU Unit
Consider the LMU's dimensions when installing in a vehicle. Ensure it fits under seats or behind trim before drilling. Cables must not be bent or constricted, as this can impede performance. The installation point must comply with environmental specifications to avoid voiding the warranty.
Typical installation locations include under the vehicle dashboard or in the trunk. Ensure accessibility for potential future wiring or connection needs.
4.2.2 Placement of Antennas
Placement of Combination and Internal Antennas: GPS performance is critical and requires a clear view of the sky, as GPS signals are weaker than cellular signals. Minimize obstructions around the antenna to ensure a 360° view to the horizon. Avoid blocking the antenna beyond 5° above the horizon, with the center of the roof being ideal. For covert installations, placement directly under the front or rear windshields is also acceptable.
Diagram Description: Visuals showing examples of good (green), OK (yellow), and poor (red) antenna placements for both combination and internal antennas on a vehicle.
4.2.3 Protection from Heat
Avoid placing the LMU near heater vents, hot engine components, or in direct sunlight. Refer to the LMU Environmental Specifications section for maximum tolerable temperature.
4.2.4 Visibility of Diagnostic LEDs
Status LEDs provide valuable operational information. Install the LMU where LEDs are easily visible for periodic checks. If troubleshooting is needed, LED status information will be required for CalAmp customer support.
4.2.5 Moisture and Weather Protection
The LMU must be located where it will not be exposed to moisture or water. While typically not a concern inside a vehicle, avoid placing it below cup holders or in areas prone to splashing when doors are opened.
4.2.6 Preventing Accidental or Unauthorized Modification
To prevent interference from drivers or others, make it difficult to disconnect antenna wiring or remove the LMU from its power source. Methods include using Tamper Proof Sealant or creating PEG Scripts to detect power loss or antenna disconnections.
5 Installing the LMU in a Vehicle
This section provides step-by-step instructions for installing an LMU in a vehicle, following the design decisions from previous sections.
5.1 Place the LMU unit in the vehicle.
The LMU is typically placed under the passenger seat or dashboard. For units with internal antennas, placement should maximize GPS performance, such as under the dash near the front windshield. Attach the LMU to the vehicle's solid body, not plastic panels. It can be concealed by removing interior trim and molding.
5.2 Connect power, ignition, and ground.
Power Input (Red Wire): Connect to a constant (un-switched) +12 VDC or +24 VDC supply, preferably directly to the vehicle battery terminal or as close as possible. Fuse this connection to not more than 5 Amps.
Ignition Input (White Wire): Connect to the vehicle ignition or an accessory line that is powered only when the ignition is on.
Ground Line (Black Wire): Connect to chassis ground.
Caution: Incorrect connection of these lines may discharge the vehicle battery.
For optimal results, connect the LMU on its own circuit. Connect power directly to the battery if possible, protected by an inline fuse. If using the fuse box, employ standard commercial wiring practices for a permanent installation, avoiding temporary clips.
DO NOT connect the power cable to the LMU at this time.
5.3 Installation Verification
Verify that the installed TTU-2830™ is functioning correctly before leaving the installation site. Check GPS and communications functions. For robust installations, verify key configuration settings like the Inbound Address and URL.
