1.1 About This Manual
The TTU-2900™ is a next generation telematics gateway that
includes a range of wireless and peripheral connectivity options
and is equipped with CalAmp's purpose built vehicle interface
technologies for both light and heavy-duty vehicle. In order to
accurately describe the functionality of these units we have
broken this manual into the following sections:
System Overview - A basic description of a
CalAmp TTU-2900™. This includes a description
of roles and responsibilities of each of the CalAmp
components as well as a brief overview of the
wireless data technologies used by the LMU-
3640™.
Hardware Overview - Describes the physical
characteristics and interfaces of the TTU-2900™.
Installation and Verification - Provides guidance
for the installation of the TTU-2900™ versions in a

Page 2: About Calamp
TTU-2900™ are sold exclusively to authorized systems integrators, software firms, and service providers who have developed their offering around the capabilities of the TTU-2900™. Customers are trained by CalAmp to integrate the mobile device with their system and to assist in support and maintenance of the devices. -
Page 3: Component Descriptions
LMU Manager is the primary support and configuration tool in the CalAmp system. It allows access to almost every feature available to the TTU-2900™. Unlike the backend software, it has the option of talking directly to an TTU-2900™ or making a request forwarded by the LM Direct server. -

Storage and Shipping One potential source of EOS is proximity of one TTU-2900™ GPS Antenna to another TTU-2900™ 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-2900™ GPS Antenna should be kept at least four inches apart from any active TTU-2900™... -

These outputs provide a high-current, open-collector driver that can sink up to 150 mA each. These drivers may be used to drive external relays that can then control vehicle functions such as door locks, fuel shut-off valves, sirens and lights. -

19:WSP 3.4.6 Status LEDs The TTU-2900™ is equipped with 4 Status LEDs; one for GPS, one for COMM (wireless network status), one for GPS, one for VBUS and one for WiFi. The LEDs use the following colors to indicate service:... -
Page 13: Configuration Of The Vehicle Bus Interface
4 Configuration of the Vehicle Bus Interface The VBU2 Vehicle Bus Interface embedded in the TTU-2900 is capable of supporting both Light Duty (cars, trucks, vans) as well as Heavy Duty (trucks and buses) vehicles. In many cases, the VBU2 interface can automatically identify the vehicle type as heavy duty or light duty(OBD). Detection of operating mode today is primarily based on the correct selection of the cable for the vehicle type. -
Page 14: Configuration And Activation
5 Configuration and Activation This section details how to quickly get an TTU-2900™ provisioned and configured to point at a specific server. It is assumed that a PEG script has already been created and is being managed through LMU Manager or PULS™, the CalAmp Maintenance System. -
Page 15: Activating Lte Using At Commands
If you get an LMU without a SIM card (which is the typical case), the operator will simply ask for the IMEI of the LMU. The IMEI (International Mobile Equipment Identifier) is printed on the label of the LMU. Again, DO NOT give the operator the CalAmp ESN of the LMU. -
Page 16: Preparing For Installation
7/21/2020 TTU-2900 Hardware & Installation Guide - PULS Wiki AT$APP PIN <SIM pin> You can confirm activation by watching the Comm LED to see if it goes solid. You may also confirm activation by entering AT command AT$APP COMM STATUS? or ATIC The activation sequence for an LTE Verizon modem would therefore look as follows: The LMU must be registered on the Verizon network. -

5.5.1 Place the TTU-2900 in the vehicle. The TTU-2900 contains an internal battery, and thus should be oriented with the label facing upwards towards the sky. LMUs with internal antennas should be placed directly under a thick panel to maximize their performance and protect from external elements.

Page 18: Connect Power, Ignition, And Ground
Inbound Address and URL should also be verified. Note that these processes are all based on issuing AT Commands to the TTU-2900™. It is expected that installers will have access to a serial port expansion cable and a laptop or PDA capable of a terminal connection. Alternatively, an SMS message can be sent to an TTU-2900™ to obtain its current status. -
Page 19: Gps Verification
5.6.3 Inbound Verification The last item to verify is that the TTU-2900™ is sending data to the correct server. In general, this is a two-step process that will need the aid of an observer on the back end. That is, a technician will have to be logged in so they can monitor data coming into the backend mapping/vehicle management application. -

7/21/2020 TTU-2900 Hardware & Installation Guide - PULS Wiki Assuming that all three sections have passed, the installation can be considered to be complete. 5.6.4 Verification via SMS The current Comm, GPS and Inbound status of a GSM LMU can be obtained via SMS provided you have access to an SMS capable phone or PDA. -
