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 TTU-4530™ 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 TTU-4530™
Host Device (GPS NMEA only)
An LM Direct™ communications server
Backend mapping and reporting software which typically includes mapping and fleet reporting
functions
PULS™
TTU Manager™

Basic System Architecture
2.2 Component Descriptions
2.2.1 Wireless Data Network
The Wireless Data Network provides the information bridge between the LM Direct™ server and the
TTU-4530™. Wireless data networks can take a variety of forms, such as cellular networks, satellite
systems or local area networks. Contact the CalAmp sales team for the networks available to the TTU-
4530™.
2.2.2 TTU-4530™
The TTU-4530™ is responsible for delivering the location and status information when and where it is
needed. Data requests mainly come from the following sources:
PEG™ script within the TTU-4530™
A location or status request from the LM Direct™ server
A location or status request from TTU Manager
An SMS request made from a mobile device such as a customer’s cell-phone
In some cases, it is necessary to run an application in the vehicle while it is being tracked by the
backend software. Such examples could include instant messaging between vehicles or a central
office, in-vehicle mapping or driving directions, email or database access. In most of these cases you
will be using the TTU-4530™ as a wireless modem as well as a vehicle-location device.
]2.2.3 LM Direct™ Server
LM Direct™ is a CalAmp proprietary message interface specification detailing the various messages
and their contents the TTU-4530™ is capable of sending and receiving. This interface allows System
Integrators to communicate directly with TTU-4530's™. Please refer to the LM Direct Reference
Guide for details.
2.2.4 Backend Software

Backend software is a customer provided software application. Regardless of its purpose, one of its
primary functions is to parse and present data obtained from the LM Direct™ server. This allows the
application to do any of the following:
Display location database on reports received from the TTU-4530™ in a variety of formats
Present historic information received from the TTU-4530™, typically in a report/chart style format
Request location updates from one or more TTU-4530s™
Update and change the configuration of one or more TTU-4530s™
2.2.5 PULS™
PULS™ (Programming, Update and Logistics System) is CalAmp’s web-based maintenance server
offering out-of-the-box hands free configuration and automatic post-installation upgrades. PULS™
provides a means for configuration parameters, PEG scripts, and firmware to be updated Over-The-Air
(OTA) and allows CalAmp customers to monitor unit health status across your customers’ fleets to
quickly identify issues before they become expensive problems.
2.2.6 TTU Manager™
TTU Manager is the primary configuration tool in the CalAmp system. It allows access to almost every
feature available to the TTU-4530™. Unlike the backend software, it has the option of talking directly to
a TTU-4530™ or making a request forwarded by the LM Direct™ server.

4 Configuration and Activation
This section details how to quickly get an TTU-4530™ 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 TTU 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
TTU-4530™. (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 TTU-
4530™. 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 TTU-4530s™ must go through a common step during the configuration and provisioning process.
Specifically, this is pointing the TTU 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 TTU-4530™ and connect a serial cable from the TTU to your laptop
2. Open a terminal session to the TTU-4530™
3. Enter the address of the LM Direct™ server:

AT$APP PARAM 2319,0,ddd.ddd.ddd.ddd
AT$APP PARAM 768,0,ddd.ddd.ddd.ddd (32-bit products only)
AT$APP PARAM 769,0,ppppp
Where ddd.ddd.ddd.ddd is the publicly addressable IPV4 address of your LM Direct™ server and
ppppp is the UDP port number.
4. Alternatively if a URL has been set up for your LM Direct™ server, the TTU may be programmed
with:
AT$APP PARAM 2319,0,myURL.MyCompany.Com
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 TTU-4530™ and your handset
2. From the handset, send an SMS message to the TTU-4530™ phone number:
!RP,2319,0,ddd.ddd.ddd.ddd
!RP,768,0,ddd.ddd.ddd.ddd (32-bit products only)
!RP,769,0,ppppp
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 TTU may be programmed
with:
!RP,2319,0,myURL.MyCompany.Com
Where myURL.MyCompany.com is the URL assigned to the server
4. Verify your settings by sending the commands:
!RP?2319,0

!RP?769,0
.2 Auto provisioning of GSM or HSPA TTUs
For certain operators, the TTU can auto-populate the APN, username and password settings based on
the Mobile Country Code (MCC) and the Mobile Network Code (MNC) of the SIM. Upon inserting a
new SIM the APN, username and password will switch to the new SIM card's defaults if the MCC and
MNC values change. The current list of supported MCC and MNC combinations are:
AT&T –formerly AT&T Wireless or Cingular Blue (MCC 310, MNC 38)
o APN 0: PROXY
o APN 1: PUBLIC

This feature can be disabled by setting Bit 0 of S-Register 155.
AT$APP PARAM 1024,35,1,1
To re-enable auto-provisioning, use:

AT$APP PARAM 1024,35,1,0
Auto-provisioning occurs when the TTU detects a SIM with a new operator ID (i.e. the first 6 digits of
the IMSI) or when Bit 0 of S155 is cleared and the GPRS context is blank (i.e. Parameter 2306,0).
4.3 Activating GSM or HSPA TTU using AT Commands
Check with the CalAmp Sales team for availability of the TTU-4530™ with GSM or HSPA
modems. For a GSM/GPRS operator you will get the TTU in one of two varieties, one with a SIM and
one without.
If you get an TTU without a SIM (which is the typical case) the operator will simply ask for the IMEI of
the TTU. The IMEI (International Mobile Equipment Identifier) is printed on the bottom of the TTU
under the TTU’s ESN. Again, DO NOT give the operator the ESN of the TTU.
The operator will provide you with a SIM for each account activated. If they are especially nice (or you
are especially persistent) they will also give you a list tying the IMSI (International Subscriber Identifier)
of the SIM to the phone number assigned to it. Please note that the operator will likely tie the IMSI (i.e.
the SIM) to a specific IMEI. Making sure the specific SIM matches to the right IMEI isn’t strictly
necessary, but it will keep everyone’s book-keeping a little cleaner. You may also obtain this
information by running a CSV report in PULS (after the devices have connected to the network and
sent in their first ID Report). See the PULS Users Guide for more information.
If you do happen to have a SIM, the operator will ask for the IMSI and ICC-ID (Integrated Circuit Card
Identifier) along with the IMEI of the TTU. Again, in return you should get a list of IMSIs and Phone
Numbers.
The IMEI, IMSI and ICC-ID are all available through the ATI1 command. The IMEI should also be
printed on the bottom of the TTU.
You should also get an APN (Access Point Name) value. The APN is the device on the network that
allows a GPRS device (i.e. the TTU) to get to the internet. They tend to look like a URL, for example:
myAPN.myOperator.com
Operators can offer more than one type of APN and can even set up a custom APN just for your
devices. The rates they charge will vary depending on the APN service you want. Operators may also
request you use a blank APN. With the APN, you should also receive a username and password
combination.
The last item an operator may provide is a SIM PIN. The PIN is effectively a password to the device.
The main difference here is that the PIN will restrict all the capabilities of the GSM device, where the
SPC is used just for configuration.

The activation sequence for a GSM TTU would therefore look as follows:
AT$APP PARAM 2306,0,“myAPN.myOperator.com”
AT$APP PARAM 2306,1,“myAPN.myOperator.com”
AT$APP PARAM 2314,0,“myUSername”
AT$APP PARAM 2315,0,“myPassword”
For a blank APN the following command can be used:
AT$APP PARAM 2306,0,“” (for a blank APN)
Only enter this next command if you have been given a non-zero PIN as any errors may lock you out
of the modem.
AT$APP PIN <SIM pin>
You can confirm activation by watching the Comm LED to see if it goes solid. You may also confirm
activation using
AT$APP COMM STATUS?
A good response should look similar to the following:
GSM Registered: Yes
GPRS Registered: Yes
Connection: Yes
RSSI: -70 dBm
BER: 0
Channel: 0
Cell ID: 0
Base Station ID: 0
Local Area Code: 0
Network Code: 38
Country Code: 310
IMEI (Modem S/N): 500167110060440
IMSI (SIM S/N): 310380100521849
Phone Number:

GPRS APN: IP:Public
Quality of Srvc: 1,0,0,3,0,0
GSM Class: B
The SIM carrier is located inside the TTU-4530™ housing on the back center of the device.

4.5 Activating a CDMA TTU-4530™
Check with the CalAmp Sales team for availability of the TTU-4530™ with CDMA modems. For CDMA
devices, the activation sequence you will use varies from carrier to carrier. Each of the supported carriers is
documented below.
To obtain an account, a CDMA carrier will generally ask for three things, the Manufacturer, the Product
Type and the ESN. Obviously the first two items are answered by “CalAmp TTU”. The last one is a
little misleading. The ESN on the TTU is the CalAmp serial number. The one the operator is interested
in is the MSN-D (which they call the decimal ESN). DO NOT give them the CalAmp ESN (i.e. the top
one on the label). It will only lead to the carrier telling you that the product doesn’t exist and they can’t
activate it for you.
What you should get back will vary from operator to operator; however at very least it will be the MDN
(Mobile Directory Number) and MIN (Mobile Information Number). You should also ask for the SPC
(Service Programming Code) in case it is not 000000. The SPC is effectively a password to the
modem which allows you to program some of the more sensitive items (ex: the MDN and MIN). Please
note that the MIN and MSID can be the same value.
4.5.1 Activating a CDMA TTU-4530™ – Verizon
Verizon supports a system that allows CDMA devices to be provisioned Over-The-Air. A CalAmp TTU-
4530™ will automatically use this system to attempt to self provision. This procedure assumes that the
TTU-4530™ has never been provisioned or activated before.
1. Power on the TTU-4530™, making sure you can observe the behavior of the Comm LED.
2. Wait until the Comm LED turns solid. This could take up to 5 minutes.
3. If after 5 minutes you observe that the Comm LED transitions from a slow blink to a fast blink
several times (i.e. more than twice) you will need to contact Verizon Wireless for further support on
account activation.
Once configured, you may verify that the TTU-4530™’s modem has registered to the CDMA network.
Enter:
AT$APP COMM STATUS?
The response should be similar to:
CDMA Service: IS-2000
Connection: Yes
RSSI: -80 dBm

Channel: 0
Band:Side: 800:B
Base Station ID: 0
Network ID: 0
System ID: 4
ESN (Modem S/N: 2676319948 [9F8566CC]
Phone Number: 1234567890
IMSI: 310001234567890
CarrierConfig: 5
Note that the Phone Number should match the MDN value the carrier gave you. The last 10 digits of
the IMSI field should match the MIN/MSID value they gave you.
For devices that have had previous activations, an Over-The-Air activation process may be manually
started using a single AT Command:
AT$APP MODEM UPDATE
This command is also used to initiate an Over-The-Air PRL Update for devices that are already
provisioned.
Users may also force a reactivation with the command:
AT$APP MODEM ACTIVATE
Keep in mind, however, this may cause the modem to lose its credentials and become unable to
register to the network.
4.5.2 Activating a CDMA TTU-4530™ – Sprint
Activating an TTU-4530™ on the Sprint CDMA network is identical to activating on the Verizon
network.
1. Power on the TTU-4530™, making sure you can observe the behavior of the Comm LED.
2. Wait until the Comm LED turns solid. This could take up to 5 minutes.
3. If after 5 minutes you observe that the Comm LED transitions from a slow blink to a fast blink
several times (i.e. more than twice) you will need to contact Sprint for further support on account
activation..
