Power
The MT 4100 accepts 9-32 VDC, minimum 2 amps input power. This allows the device to be used on
both 12 V and 24 V vehicles per SAE specifications, including protection for jump-starting 24 V vehicles.
Pins 17 and 18 on the 22-Pin IO connector are the power input and pins 6 and 7 are ground.
All power and ground pins must be connected.
Power Consumption
Mode Current GPS
CDMA BC0 - 800 MHz < 66 mA @ 14.2 V GPS off; lowest current consumption while still
being able to contact the device
CDMA BC1 - 1900 MHz < 63 mA @ 14.2 V GPS on
Idle (GPS on) < 54 mA @14.2 V Registered
Idle (GPS off) < 33 mA @14.2 V Registered
Low Power Sleep Mode <1.3 mA @14.2 V GPS off
Bench Testing / Programming
WARNING! After performing a firmware upgrade the device will respond that the firmware load is
complete. However, power must remain applied to the device for approximately two minutes after the
firmware upgrade completion message is received. This allows time for the upgrade to be applied to
the auxiliary processor. The user can confirm it is safe to remove power by sending the AT$OBDVER?
command. If the upgrade is still processing, the device will respond with an error. If the upgrade is
complete, the device will respond with the current software version.

LEDs
The MT 4100 includes LEDs to indicate Power, GPS, and Registration status. The following image shows
the location of each LED.
The LEDs are described in the following table.
MT 4100 LEDs
PWR: This LED indicates power to the GPS module. LED is on ~1 second after powered on and
the GPS module is operational. This LED is off when powered off or when the MT 4100
enters Low-Power Sleep mode. Note: If you disable the GPS module, you must apply
power for this LED to turn on.
GPS: You can configure this LED to display registration, GPS fix status, or other user functions.
By default, this LED indicates GPS fix status. The LED remains off when it receives invalid
GPS data. The LED remains on when it receives valid GPS data.
Registration: You can configure this LED to display registration or other user functions. By default, this
LED indicates network registration status. If this LED stays off, this indicates that the device
is not attempting to register to the network. If the LED blinks, it indicates that the device is
trying to connect to the network. If the LED is always on, this indicates that the device has
connected to the network.

Battery Disconnect Switch
Use the MT 4100 Battery Disconnection Switch to remove battery power from the device (battery
models only). Move the switch toward the dot to place the battery in the ON position. Move the switch
away from the dot to place the battery in the OFF position. The following figure shows the MT 4100
Battery Disconnection Switch in the OFF position.
You must place the Battery Disconnection Switch in the ON position before using the optional backup
battery for programming or operating the MT 4100.
WARNING! If the Battery Disconnection Switch remains in the ON position with no external power
applied for an extended period of time, then the battery may significantly lose its charging capability.
WARNING! Before connecting to any auxiliary I/O device, you must apply power to the MT 4100 by
moving the Battery Power Switch to the ON position. Failure to apply power to the MT 4100 before
connecting auxiliary devices may result in damage to the attached I/O device.
NOTE: Move the Battery Disconnection Switch to the OFF position when transporting the device by
air.

MT 4100 User Guide 12
Low-Power Sleep Mode
In Low-Power Sleep Mode (LPS), all modem/GPS activity stops; this allows extreme power savings. The
auxiliary processor efficiently monitors system inputs based on the configuration assigned and will exit
LPS mode when needed. The current draw during LPS is:
< 1.5 mA @ 12 V
You can configure the MT 4100 to exit Low-Power Sleep Mode when:
lIgnition detected
lMotion detected
lInput triggered
lElapsed-time expired
For more details, see Novatel Wireless document Power Saving Techniques Application Note
(ENF0000AN015).

Accelerometer
The MT 4100 has two, three-axis digital accelerometers that provide the following features:
lMotion alert (towing alert)
lDriver behavior reporting
oRapid acceleration
oHarsh braking
lConfigurable thresholds
oRange settings
oMode (Normal, Sleep, Wakeup)
oWakeup pause (20 to 2560 msec)
oSample Rate (0 to 25 per second)
oFilter Coefficient and Filter Bandwidth
oDevice Orientation Setup
For more information, please refer to Novatel Wireless document Accelerometer Guide Application Note
(ENF0000AN003).

MT 4100 User Guide 14
1-Wire® Interface
The MT 4100 includes a 1-Wire® interface that enables the device to communicate with the following
accessories:
lAn iButton® receiver to allow for Driver ID (iButton® and receiver not included)
lUp to two 1-Wire Temperature Sensors
For more information, see the Novatel Wireless document 1-Wire Application Note (ENF0000AN018).
WARNING! The maximum permissible voltage to the 1-Wire® interface is 3.3 Volts DC. Voltage in
excess of this limit will damage the device.

Device Check-In
The device check-in feature provides connectivity to "configuration-only" servers. The device performs a
“check-in" to these servers periodically for configuration updates. A check-in is similar to a wake-up
message. The server then configures the device using AT commands after establishing a UDP
connection.
This feature has AT$CHKIN command available and requires Novatel Wireless CMS software version 3.1
or higher. For more information, see MT 4100 R ATCommand Reference (MT4100R-AT144) or MT4100
UATCommand Reference (MT4100U-AT144).

Garmin Fleet Management Interface (GFMI)
NOTE: The Garmin Fleet Management Interface (GFMI)feature is available for separate purchase.
Contact your Novatel Wireless sales representative for information.
GFMI provides the MT 4100 with a Wireless Network back-end to allow the Garmin Portable Navigation
Device (PND) to communicate with a server.
Garmin has defined and published the GFMI Control Specification. The GFMI defines the message
protocol that the PND supports over the 9600 baud serial line. If a device has GFMI enabled, the MT
4100 will support this protocol and transmit and receive requests back to the server.
For more information, see Novatel Wireless document GFMI Technical Guide (ENF0000XG001).
