1.4 About the CalAmp Location Messaging Unit - LMU-3640™
The CalAmp Location and Messaging unit-LMU-3640™ is a mobile device that resides in private, commercial or government vehicles. The
LMU-3640™ is a single box enclosure incorporating a processor, a GPS receiver, a wireless data modem, and a vehicle-rated power supply. The
LMU-3640™ also supports inputs and outputs to monitor and react to the vehicular environment and/or driver actions..
The LMU-3640™ collects, stores and transmits vehicular and location data over a designated wireless network including LTE and HSPA.
Vehicular and location data are transmitted to a customized software application that has been designed to receive, acknowledge, process, store,
and respond to this data.
Unit location and vehicular information is sent at pre-determined intervals, on demand, or when pre-programmed vehicular conditions are met.
Transmission of data are sent immediately when in wireless network coverage and stored for later transmission when out of the wireless coverage
area. SMS messaging can be used as an alternative or redundant communication backup.
The LMU-3640™ is designed to support a variety of custom fleet applications starting with basic automatic vehicle location and including
applications requiring more sophisticated features such as geo-fencing, speed and mileage monitoring, third party security monitoring, dynamic
reporting routines, and an array of exception alerts.

around the capabilities of the LMU-3640™. Customers are trained by CalAmp to integrate the mobile device with their system and to assist in
support and maintenance of the devices.
Installations of LMU-3640™ are performed by CalAmp customers or contracted installers. Typical installations include hook-up to power,
ignition, and ground. LMU-3640™s and the corresponding wiring are almost always hidden from view and general access. Placement of the units
is usually under dashboards, in trunks or in compartments.
2 System Overview
2.1 Overview
The entire purpose behind a fleet management system is to be able to remotely contact a vehicle, determine its location or status, and do
something meaningful with that information. This could include displaying the vehicle location on a map, performing an address look-up,
providing real-time driving directions, updating the vehicles ETA, monitoring vehicle and driver status or dispatching the vehicle to its next pick
up.
These functions, of course, are completely dependent on the capabilities of the vehicle management application. The role of the CalAmp LMU-
3640™ is to deliver the location information when and where it is needed.
A typical fleet management system based on a CalAmp device includes the following components:
A wireless data network
An LMU-3640™
Host Device (GPS NMEA only)
An LM Direct™ communications server
Backend mapping and reporting software which typically includes mapping and fleet reporting functions

3.4.1 3-Axis Accelerometer Input
The LMU-3640™ supports an internal 3 Axis Precision Accelerometer as one of its discreet inputs. When the LMU is moved in any direction, the
associated input will be in the High state. If the LMU’s accelerometer does not detect motion, then the input will be in the Low state. No external
connections are required for this functionality to be operational.
3.4.2 Ignition and Inputs
The LMU-3640™ provides up to 7 inputs. These inputs are protected from typical vehicle transients and can be directly connected to most vehicle
level logical inputs from 4 volts up to the vehicle power input level (typically 12 VDC). Their input impedance is approximately 10kO. One of
these inputs is dedicated to sensing the vehicle’s ignition status to provide for flexible power management. The other two inputs may be used to
sense vehicle inputs such as cooling unit operation, a hidden driver “Panic” switch, taxi on-duty/off-duty meter status or many others.

https://puls.calamp.com/wiki/LMU-3640_Hardware_%26_Installation_Guide 10/23
The ignition input is pulled to ground through the 10k resistance, where the other inputs can be configured to be normally High (i.e. pulled to
+12v through a 10k resistor) or Low (i.e. pulled to ground through a 10k resistor). The diagrams below show how to connect the inputs in both a
high- and low-biased configuration:
LMU-3640™ Input Wiring
3.4.3 Outputs
The LMU’s and ioPOD;s outputs are designed to drive external relays. 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. If additional current is required to drive the relays, external circuitry can be added to source the current. This diagram is a typical
use of an output to drive a relay.

4 Configuration and Activation
This section details how to quickly get an LMU-3640™ 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.
We are making three assumptions to simplify the setup process:
You have created, installed and configured an LM Direct™ Server to receive messages from the LMU-3640™. (See LM Direct™
Reference Guide for details)
You are using the standard wiring harness from CalAmp and the serial port expansion harness.
You have created a HyperTerminal or Putty session.
You have contacted the CalAmp sales team regarding the network availability of the LMU-3640™. This device may not be supported
for all the carriers or networks listed in this section (CDMA-Verizon, CDMA-Sprint, HSPA, GSM), for product availability consult the
CalAmp sales team.
4.1 Quick Start - General Config
All LMU-3640™s must go through a common step during the configuration and provisioning process. Specifically, this is pointing the LMU to
your LM Direct™ server, either via IP or a URL.
This configuration process is accomplished via a series of AT Commands:
1. Power up the LMU-3640™ and connect a serial cable from the LMU to your laptop
2. Open a terminal session to the LMU-3640™
3. Enter the address of the LM Direct™ server:
Where ddd.ddd.ddd.ddd is the publicly addressable IPV4 address of your LM Direct™ server and ppppp is the UDP port number.
4. Alternatively if a URL has been set up for your LM Direct™ server, the LMU may be programmed with:
Where myURL.MyCompany.com is the URL assigned to the server.
5. Enter ATIC to verify the correct settings are displayed for your Inbound Server.
This configuration process is accomplished via a series of SMS Commands:
1. Power up the LMU-3640™ and your handset
2. From the handset, send an SMS message to the LMU-3640™ phone number:
Where ddd.ddd.ddd.ddd is the publicly addressable IPV4 address of your LM Direct™ server and ppppp is the UDP port number
3. Alternatively if a URL has been set up for your LM Direct™ server, the LMU may be programmed with:
AT$APP PARAM 2319,0,ddd.ddd.ddd.ddd
AT$APP PARAM 768,0,ddd.ddd.ddd.ddd (32-bit products only)
AT$APP PARAM 769,0,ppppp
AT$APP PARAM 2319,0,myURL.MyCompany.Com
