hardware precautions
Location Messaging Unit-TTU-2830™
Anytime the sub assembly is shipped and it is not fully packaged in its final housing it must be sealed in an ESD safe bag.
Electrical Over-Stress (EOS)
The GPS receiver can be damaged if exposed to an RF level that exceeds its maximum input rating. Such exposure can happen if a nearby source transmits an RF signal at sufficiently high level to cause damage.
Storage and Shipping
One potential source of EOS is proximity of one TTU-2830™GPS Antenna to another TTU-2830™GSM Antenna. Should one of the units be in a transmit mode the potential exists for the other unit to become damaged. Therefore any TTU-2830™GPS Antenna should be kept at least four inches apart from any active TTU-2830™GSM Antenna or any other active high power RF transmitter with power greater than 1 Watt.
Battery Back-up devices
Please properly dispose of the battery in any of the CalAmp products that utilize one, do not just throw used batteries, replaced batteries, or units containing a back-up battery into the trash. Consult your local waste management facility for proper disposal instructions.

motion sensor input
The TTU-2830™ supports an internal motion sensor as one of its discreet inputs. In this case, the TTU detects motion and will determine if the device is moving for at least 30 consecutive seconds. If it is moving the device will track at a 5 minute interval for about 350 messages.
power state input
The TTU-2830™ can detect if it’s using external power or if it’s using its internal back-up battering. If the TTU-2830™is using external power, this input will be in the Low state. If they have switched to the internal battery, then the input will register in the High state.
status leds
The TTU-2830™ is equipped with two Status LEDs, one for GPS and one for COMM (wireless network status). The LEDs use the following blink patterns to indicate service:

installation
preparing for installation
Be sure you have received all the TTU components you need. This must include:
- The LMU to be installed
- A power harness
- Optional Components:
- Input and output cables
plan the installation
Verify Power, Ground and Ignition. Be sure to check each source (power, ground and ignition) to ensure that the proper signaling exists. This is typically accomplished with a multi-meter.
Before drilling any holes or running any wires, decide where each hardware component will be located (TTU, peripherals, etc.). Be sure that the cables to the TTU are not bent or constricted in any way.
Be advised that an installation that violates the environmental specifications of the LMU will void the warranty.
size and placement of TTu unit
The dimensions of the TTU should be taken into account, particularly when installing in a vehicle. Whether you intend to place the TTU under a seat or into a cavity behind the vehicle’s interior molded trim, be sure the TTU will fit before drilling any holes or running cable.
Typical installations will place the TTU under the vehicle dash board, or in the trunk. Make sure you can get access to the unit afterwards as under some circumstances it may be necessary to add additional wiring or connections to the TTU.
protection from heat
It is best not to place the TTU unit in an unusually warm location such as directly near heater vents, near hot engine components or in direct sunlight. The maximum temperature that can be tolerated by the TTU is described in the TTU Environmental Specifications section.
visibility of diagnostic LEds
Status LED lights on the front of the TTU unit can provide valuable information about the operation of the TTU. When feasible, attempt to install the TTU in such a way that these lights can be seen with reasonable ease.
You may find it useful to be able to view the LEDs periodically to make sure that theTTU is operating properly. If at any time you should encounter a problem with the TTU, you may need to read the LEDs in order to troubleshoot the problem. If you cannot fix the TTU yourself, you will need to provide the LED information to ThingTech
customer support.
For information about how to interpret the LEDs, see the Status LED Behavior section.
preventing accidental or unauthorized modification
If you anticipate that fleet drivers or others might interfere with the LMUs once they are installed, take steps to be sure that it is not easy to disconnect the antenna wiring, remove the LMU from its power source, etc. Two common methods are the use of Tamper Proof Sealant or creation of PEG Script to detect power loss or GPS antenna disconnections.
installing the TTU in a vehicle
This section provides instructions for installing an TTU in a vehicle. Be sure to consider the design decisions described in the previous sections. When you are ready to begin installing the TTU, follow these steps:
place the ttu unit in the vehicle
Typically, the TTU should be placed under the passenger seat or dashboard of the vehicle. TTUs with internal antennas should be placed to maximize their GPS performance. A typical location include under the dash close to the front wind-shield. Attach the TTU to the solid body of the vehicle, not to plastic panels. The TTU can be placed out of sight by removing interior trim and molding to expose available space, then replacing the trim once the TTU is in place.
connect power, ignition, and ground
The power input (red wire) must be connected to a constant (un-switched) +12 VDC or +24 VDC supply; preferably, connected directly to the vehicle battery terminal or as close to it as possible. This connection point should be fuse protected to not more than 5 Amps. The ignition input (white wire) must be connected to the vehicle ignition or another
appropriate key operated line, such as ACCESSORY, ensuring that power to the ignition wire is available only when the vehicle ignition is on. The ground line (black wire) must be connected to chassis ground. Failure to connect these lines in the manner described may result in discharge of the vehicle battery. For best results, it is strongly recommended that the TTU connection be on its own circuit. Connect the power input directly to the vehicle battery if possible and protect the
circuit with an inline fuse. If you must connect through the fuse box, use standard commercial wiring practices to create a permanent installation rather than using press-in fuse clips or other temporary measures.
installation verification
Once the TTU has been installed, please wait up to 5 minutes for the TTU to acquire signal.
When the TTU has acquired signal, turn the key ON for 30 seconds, then OFF. Repeat this step.
If power is not available during the installation, ground the orange wire for 5 seconds. This will allow the TTU to power up for 20 minutes on it's own battery power.
Verify the LED status indicators:
- Orange (Comm LED): LED will flash slowly when the key is in the OFF postion, solid in the ON position. If the amber light flashes rapidly in the ON position, service has not been established.
- Green (GPS LED): LED will flash when GPS has been established.
If LEDs do not function as stated, check all connections. Verify power, ignition and ground at the TTU.
Send the ESN, VIN, and any other pertinent information about the device and vehicle to your ThingTech consultant.
