2.3 On-Board Diagnostics Overview
An On-Board Diagnostics (OBD) system controls engine functions and serves as the diagnostic control
network of the vehicle. All cars built and sold in the United States since 1996 must be equipped with the
newer OBDII system. The Enfora MT 3050 connects to a vehicle's OBDII port and monitors the OBDII
system using a variety of communication protocols.
The MT 3050 can be configured to provide notification messages based on events triggered by:
Accelerometer change
Check engine light (MIL alert)
Engine RPM
GPS information
Idle time
Low fuel
Trip Odometer (trip distance)
Vehicle battery voltage (low battery warning)
Vehicle Identification Number (VIN)
Vehicle speed
Other events monitored by the OBDII system
Some vehicles are not compatible with the MT 3050. If the vehicle is not compatible
with the parameters the MT 3050 requires, then functionality may be limited,
problematic, or unavailable.
The SAE (Society of Automobile Engineers) 1979 standard defines the method for requesting diagnostics
data and provides a list of standard parameters from the engine control unit.
Compliance to this standard is the responsibility of the vehicle manufacturer, therefore Enfora cannot
guarantee performance of the MT 3050 with every vehicle.

3.7 New Event Reporting
The MT 3050 has additional event reporting not supported by other Enfora products. For general event
reporting information and for detailed information about these new events refer to the MT 3050 AT
Command Document (GSM2374AT001).
3.7.1 Vehicle Identification Number (VIN)
The VIN is used as a unique identifier which is sent at first power up with heartbeat messages and with
events.
Vehicle manufacturers are responsible for defining the list of data returned,
therefore not all vehicles support retuning the Vehicle Identification Number.
3.7.2 Excessive Engine Speed (RPM)
Excessive engine speed alerts are triggered when the engine speed (in RPM) exceeds a defined RPM level
(in ¼ RPM increments) for a defined period of time in seconds (e.g., 30 seconds).
The MT 3050 has three definable thresholds.
Unnecessary wear and tear on the powertrain control module (PCM) may occur if constant or frequent
excessive engine speed is reported. The excessive engine speed event may be caused by one of the
following situations:
Obstructions, such as ice or mud, that may cause wheel slippage if the obstruction is not removed
from the vehicle
Revving the RPM while in neutral
Speeding or reckless driving that causes excessive RPM engine speed
The following AT command example sets the excessive engine speed threshold at 1 to 4000 RPM. Then, if
exceeded for 3 seconds, it triggers the input event. This event will clear once engine RPM is below 4000 for
30 seconds.
AT$OBDEES=1,4000,3,30
-8-
3.7.3 Vehicle Speed
If configured for vehicle speed alerts and the vehicle moves faster than one of the three configurable
thresholds (e.g., 70 MPH), then a vehicle speed alert is triggered.
The following AT Command example sets the vehicle speed threshold at 1 to 112 KPH (~70MPH). When the
threshold is exceeded for 10 seconds, an input event is triggered. This event will clear when the vehicle
speed is reduced to 104KPH (~65MPH).
AT$OBDSPD=1,112,10,104
3.7.4 Vehicle Battery Voltage (Low Battery Warning)
The vehicle battery voltage alert is triggered when the vehicle’s battery is reported to be below a threshold
(e.g., 10.8 V) for a user-defined period of time in seconds (e.g., 300 seconds).
The following AT Command example sets the low battery threshold to 10.8 volts. When the voltage
remains below this threshold for 300 seconds (5 minutes), it triggers an input event. Restoring voltage
above the threshold for 300 seconds (5 minutes) will clear this event.
AT$OBDLBL=10800,300,300
3.7.5 Check Engine Light (MIL Alert)
When the vehicle's “Check Engine” light illuminates, this indicates that a vehicle issue requires attention
for diagnosis and/or repair. This is also known as a Malfunction Indicator Light (MIL). A user can configure
a device to detect a MIL issue through the OBDII protocol, and to send an alert when the device detects
such an issue.
3.7.6 Trip Odometer Reporting
Trip odometer reporting provides the odometer miles accumulated from ignition-on to ignition-off, which
is considered a “trip”.
Ignition events are not yet detected on hybrid or electric vehicles.
-9-
3.7.7 Idle Time Reporting
An idle time event is triggered when the vehicle’s engine is running without the vehicle moving (i.e.,
velocity less than 3 KPH) for a defined period of time in seconds (e.g., 300 seconds).
The alert is cleared when the vehicle speed exceeds another speed and time threshold.
Both the violation and clearing of the alert are reported if configured.
The following AT Command example sets the idle time speed threshold to 3 KPH for 5 minutes (300
seconds) with a clearance time of 30 seconds. If the speed remains below this threshold for 300 seconds (5
minutes), it triggers the input event. Restoring speed above this threshold for 30 seconds will clear this
event.
AT$OBDIDL=3,300,30
3.7.8 Low Fuel Alert
The low fuel alert triggers when the vehicle’s fuel level falls below a defined threshold in percent (e.g.,
12%) for a defined period of time in seconds (e.g., 60 seconds).
The following AT Command example sets the low fuel alert threshold to 12% for 1 minute (60 seconds)
with a clearance time of 30 seconds. If the fuel level remains below this threshold for 60 seconds, it
triggers the input event. Restoring the fuel level above this threshold for 30 seconds will clear this event.
AT$OBDLFL=12,60,30
3.7.9 Rapid Acceleration
Rapid acceleration events can be triggered when one of three available thresholds are exceeded as
determined by the accelerometer in milli-Gs (e.g., 0.75) for a defined period of time in seconds (e.g., 30
seconds).
The following AT Command example sets the rapid acceleration threshold #1 to .2G. If this threshold is
exceeded for 1 second, then an input event is triggered. Keeping the acceleration of the vehicle below this
threshold for 30 seconds will clear this event.
AT$OBDACL=1,200,1,30
3.7.10 Sudden Deceleration (Harsh Braking)
Rapid deceleration events can be triggered when one of three available deceleration thresholds are
exceeded as determined by the accelerometer in milli-Gs (e.g., 1.0) for a defined period of time in seconds
(30 seconds).
- 10 -
The following AT Command example sets the rapid deceleration threshold #1 to .5Gs. If this threshold is
exceeded for 1 second, then an input event is triggered. Keeping the deceleration below this threshold for
30 seconds will clear this event.
AT$OBDDCL=1,500,1,3
3.7.11 Motion Detection
Motion alerts for vehicles can be configured to communicate that a vehicle is being towed. Motion
detection based on measuring movement via the accelerometer occurs when the vehicle ignition is off,
and the vehicle is stationary.
A motion alert is triggered when motion defined in milli-Gs is detected for a defined period of time.
3.7.12 OBDII Basic Event Data
Five additional data items can be included with event messages:
VIN
Firmware version ($PKG)
OBD Protocol (i.e., J1850 PWM)
Cellular signal strength (RSSI)
OBD speed
3.7.13 Right Turn
Harsh turn events can be triggered when one of two available thresholds are exceeded as determined by
the accelerometer in milli-Gs (e.g., 0.75) for a defined period of time in seconds (e.g. 30 seconds).
The following AT command example sets the Right Turn accelerometer threshold 1 to .25 Gs. If this
threshold is exceeded for 2 seconds, trigger the input event. This event will clear in 15 seconds when the
acceleration is below this threshold.
AT$OBDART=1,250,2,15
3.7.14 Left Turn
Harsh turn events can be triggered when one of two available thresholds are exceeded as determined by
the accelerometer in milli-Gs (e.g., 0.75) for a defined period of time in seconds (e.g., 30 seconds).
The following AT command example sets the Left Turn accelerometer threshold 2 to .3Gs. If this threshold
is exceeded for 1 second, trigger the input event. This event will clear in 20 seconds when the acceleration
is below this threshold.
AT$OBDALT=2,300,1,20
- 11 -
3.7.15 Up
Up accelerometer events can be triggered when the threshold is exceeded as determined by the
accelerometer in milli-Gs (e.g., 0.75) for a defined period of time in seconds (e.g., 30 seconds).
The following AT command example sets the Up accelerometer threshold to 1.2Gs. If this threshold is
exceeded for 1 second, trigger the input event. This event will clear in 30 seconds when the acceleration is
below this threshold.
AT$OBDAUP=1,1200,1,30
3.7.16 Down
Down accelerometer events can be triggered when the threshold is exceeded as determined by the
accelerometer in milli-Gs (e.g., 0.75) for a defined period of time in seconds (e.g., 30 seconds).
The following AT command example sets the Down accelerometer threshold to .8Gs. If this threshold is
exceeded for 1 second, trigger the input event. This event will clear in 30 seconds when the acceleration is
below this threshold.
AT$OBDADN=1,800,1,30
3.8 Micro USB Connector
The MT 3050 includes a J1962 compliant OBDII connector and a micro USB I/O port.
The Micro USB (2.0) connector is an input/output connector and is not intended for
general use. This connector should only be used when programming the modem.
This USB port cannot be used to supply power to other USB devices and nothing
should be connected to this port when the vehicle is in motion. The MT 3050 can not
be powered through the USB Port.
The micro USB connector is only used to program the modem. When programming the modem, a micro
USB cable is required which you must purchase separately.

3.9 Additional Software Features
3.9.1 AT Commands Over SMS
A user can send AT commands to the MT 3050 via SMS. Please refer to Enfora Application Note
ENF0000AN012 - AT Commands Over SMS for details..
3.9.2 Store/Transmit Event Data
The user can configure the MT 3050 to store event-generated data in its internal memory to be sent over
the air to a remote server. This feature can be enabled or disabled using the AT$MSGLOGEN command.
“Total Number of Unread Messages” is decremented if an unread message is read via the AT$MSGLOGRD
command.
Example: Assume there are 50 unread messages in the message queue, and the total number of messages
in the message queue is 100. This means that the first 50 messages have been read while the last 50
messages have not been read. If a user sends AT$GPSLOGRD=0,1,51 then the total number of unread
messages drops down to 49 after successful transmission of that message. However, if a user sends
AT$GPSLOGRD=0,1,99 then the total number of unread messages still remains at 50—that message is
transmitted to the remote server.
A user can also read a message stored in the memory by inputting the appropriate starting index number.
3.9.3 Synchronize RTC Time With GPS Time
The Real Time Clock ("RTC") is synchronized with GPS time automatically every time the device is powered
up and first acquires valid GPS data. Additionally, the RTC time is synched with GPS time every time the
GPS time rolls over from 23:59:59 to 00:00:01.
- 13 -
3.9.4 Reporting Frequency
The minimum reporting frequency of the device is as follows:
Periodic reporting is limited to max of 1 per 6 seconds.
The general reporting interval is 1 message every 2 seconds.

Figure: 10 - MT 3050 With Cover Removed
- 16 -
4.1.2 Inserting The SIM
Insert the SIM using the following procedure:
The SIM card is not provided with the MT 3050 device. The SIM must be obtained
from the GSM/GPRS service provider and must be provisioned by the operator for
data. Always take care to protect the SIM. Without the SIM installed, the MT 3050
modem is not able to communicate on the network.
1. Using the correct tool, carefully remove the device cover to access the internal SIM holder as previously described.
2. Insert the SIM into the SIM holder of the MT 3050.
3. Replace the cover as described in the next section.
4.1.3 Closing The Device
Replace the MT 3050 cover by using the following steps:
A. Place the MT 3050 cover onto the base as shown in the following figure.
1. Apply gentle downward pressure to the back of the cover first as you carefully slide the cover
into place.
2. Apply gentle down and forward pressure to the front of the cover until it snaps shut.
Figure: 11 - MT 3050 Cover Replacement
- 17 -
4.2 Activating The Device
With CDMA devices, the user must contact the service provider to activate the device. They will need to
provide the MEID of the device to the provider. Once the provider has acknowledged that the device is
ready to activate, the user will then be required to send an activation string to the network.
Send the activation string: AT+CDV*22899. This will initiate a call with the network. A successful call will
last approximately 40 seconds. If the call is terminated within 10-15 seconds, the call was not successful.
Several attempts might be required. If after, a few attempts the call is not successful, please check the
MEID of the device and compare it to the MEID provided to the provider.
To verify that the activation has successfully completed, attempt a voice call AT+CDVxxxxxx. If the call is
successful, then the OTASP (Over-the-Air Service Provisioning) was successful.
4.3 Device Installation
Make sure the vehicle is parked on level ground prior to installing the MT 3050.
Instructions provided in this section describe the hardware installation of the MT 3050 device. To install
the MT 3050 in a vehicle, follow these steps:
1. Locate the OBDII socket. The location will vary between different vehicle manufacturers, models,
and production years.
2. Carefully insert the MT 3050 into the OBDII socket.
3. After the device is installed, ensure the device is working properly as evidenced by a GPS lock and cellular connection, which can be validated by the LEDs.
The MT 3050 is NOT a waterproof or sealed device. Care must be taken to ensure the
device is kept away from water or any other liquids.
- 18 -
Figure: 12 - Typical OBDII Socket Location
The device starts the accelerometer auto-calibration process immediately after the
device is installed and the vehicle's ignition is turned on.
4.4 Accelerometer Calibration
The accelerometer undergoes an automatic calibration sequence on the first drive after any of the
following events:
Device installation
Software upgrade
Vehicle battery replacement (or recharge if battery was fully discharged)
Device auxiliary processor reset
- 19 -
Failure to follow the process below could cause an undesired behavior of the motion
feature. Failure to drive straight on level ground during the automatic calibration
may reduce the accuracy of the accelerometer and have an adverse impact on events
triggered by accelerometer readings.
1. Make sure the vehicle is parked on level ground prior to installing the MT 3050.
2. Drive the vehicle in a straight path on level ground during the automatic calibration. An inclined surface will put part of the gravity vector into the XY plane, which will affect the acceleration thresholds. (A 5.7 degree angle will place 10 % of the gravity vector into the XY plane.)
When the vehicle passes 32 KPH, the auxiliary processor assumes that the vehicle is
moving in a straight line and determines the forward axis.

5 Network Test Procedure
Use the following instructions to configure the Enfora modem to communicate with the Enfora test server.
5.1 Configuring The Modem For Test Server Connection
To configure the modem for server interoperability, consider the following:
Most configurations are Mobile Originate only.
Mobile modem initiates a conversation with a remote server before it can talk to the modem.
IP addresses are dynamically assigned and can change.
Some IP addresses are NAT and are non-routable.
These issues are addressed in the following configuration commands.
Modem ID/name = “My_MT_TEST”
Remote Server address = http://apitest.enfora.com/UDPAPP/
Remote Server IP port = 1721
Give the modem a unique name with the following command:
AT$MDMID="My_MT_TEST"
This command, combined with the wakeup message will allow the server to associate
a Public IP address with a specific modem, and can create an opportunity where the
server can send commands to the modem.
Configure the modem to talk with a specific server with the following command:
AT$FRIEND=1,1,”apitest.enfora.com”
Set the port number with the following command:
AT$UDPAPI=,1721
Set up the server to send out periodic wakeup messages every 60 seconds with the following command:
AT$WAKEUP=1,1
- 35 -
5.2 Verifying Server Connectivity
For the following tests, ensure that you have Java Runtime installed on your computer. To install Java
Runtime, please visit the Java website here: http://www.java.com/en/download/manual.jsp
1. Start a web browser and enter the following URL:
http://apitest.enfora.com/UDPAPP/
Figure: 31 - apitest.enfora.com/UDPAPP/ Window
2. Enter the name used in the Modem ID (MDMID) command in the box.
3. Select Connect.
- 36 -
4. Select the tab with the modem name (My_MT_Test). Within approximately 60 seconds you should
see a wakeup message in the window.
Selecting the Clear button will erase the contents from the (ASCII Data) window.
5. Enter the following command in the Command/Data text box:
ATI
6. Click on the Submit button.
7. Verify that you see the modem response: Enfora, Inc.
If so, you have successfully configured the modem to talk with the server.

6 Accesories
The following accessories are available for the MT 3050:
Part Name
Part Number
Plastic Lever
ASA-3000-0001
Backup Battery
TBD
6.1 Backup Battery
The backup battery's primary function in the MT 3050 is to provide the ability for a user to be notified
when the device is removed from the vehicle.
Input Event 63 can be used to trigger an output event that can be configured in the same manner as the
other output events. If the modem is off (power savings), it will be turned on. If GPS data is configured in
the output event, and the data is not available, the last known position can be configured to be used in the
output message.
AT$OBDBBT is used to configure the time (in seconds) that the device will stay powered after removal
from the vehicle. The range is 30-6000 with the default being 600. In addition, to prevent damage to the
battery, the device will turn itself off when the battery reaches the level determined to be the lowest
“safe” value.
If the configured output message has not been sent when the timer or battery level dictates the device to
shut down (and is configured to do so), it will be saved and sent the next time the device registers on the
network.
The following figures show the battery and the connector cable.
