3 Device Mounting Options
3.1 Screw Mounting
The XT4971A has two flanges (two holes per) at each end of the housing for screw mounting the
device to the mounting surface.
3.2 3M VHB Tape Mounting
For a semi-permanent option, the device can be mounted with 3M VHB tape as shown below:
3.3 Trailer Cradle Mounting
An optional trailer mounting cradle can be purchased for easy device mounting for the XT4971A.
The cradle will need to be screw-mounted or VHB Tape mounted to the position desired. The
XT4971A can be easily fastened into the cradle via a Phillips head screw. The angled edged of the
cradle is designed to withstand the impact of snow scrapers that may come in contact to the
cradle if mounted on the top of a typical trailer.
3.4 Container Cradle Mounting
An optional container cradle can be purchased for easy device mounting for the XT4971A. The
cradle will need to be screw-mounted or VHB Tape mounted to the position desired. The
XT4971A can be easily fastened into the cradle via a Phillips head screw. The shape of the cradle
is designed to fit in the corrugations of an ISO standard freight container.
3.5 Device Mounting Guidelines
The XT4971A Series devices leverage solar energy to replenish the charge of its battery. Please
consider the device mounting guidelines to maximize device solar charging. Also, the XT4971A
series uses cellular and GPS technologies whose signal reception quality is depending on
mounting location and style. Adhering to these guidelines will optimize the field performance of
the XT4971A:
•
If possible, have the solar panel facing directly towards the noon sun. At least have the
solar panel no greater than 90° away from the noon sun.
•
•
Avoid mounting the XT4971A were shadows may cast upon the solar panel
Avoid placing unit inside a container made from any conductive materials or partially
mounted into a bracket made from any conductive materials. Doing so may potentially
degrade GPS and cellular reception.
Avoid mounting the XT4971A in low locations where dirt, grease, or any other staining
particles can be introduced by rotating wheels. Excess dirt, grease, or staining materials on
the solar panel will reduce the amount of charge the device can receive.
•
•
Avoid mounting the XT4971A to locations that are high risk to predictable physical harm.
(I.e. do not mount the unit on the top of an asset if snow scrapers are utilized in periodic
maintenance of the asset without some sort of protective bracket)

4 Quick Start Guide
4.1 Device Wakeup
To start up the device, simply hold the black button located near the circular connector on the
side panel of the device for 3 seconds. You should see the blue “C” LED light up and then fade out.
The blue LED will blink when the device is successfully connected to the network. Refer to table
in section 2.3 for LED behavior.
Wake up Button
Note: The factory default settings are configured to have the device to sleep within 2 minutes of
wake. Consider pulling the IN1 wire high to keep the device awake for configuration purposes or
disable sleep by issuing the proper 3017 command.

4.2 Configuring the Device via SMS
1)
2)
3)
4)
5)
6)
7)
8)
Ensure your device is active on your cellular account.
Awaken device from sleep XT4971A via the “wake-up” button.
If the device needs more power, then supply 12V DC via the red wire of the cable harness.
Ensure device cellular LED is blinking based on LED definition in this document.
Using your mobile phone or SMS gateway send +XT:1008 command to the device MDN
Command: “+XT:1008,”- Sets SMS Number
Response (via SMS): $$,<1008>,##
Once you have set SMS to reply to your mobile or gateway, you can now send other
commands to device via SMS per device protocol documentation.
a. Command +XT:1010 configures network settings
b. Command +XT:3017 configures the sleep/wake mode for the device.
i. The factory defaults for this device is to operate in the sleep timer mode and
have a minute of wake time max. You may need to temporarily disable sleep
in order to configure the unit uninterrupted by sleep.
c. Command +XT:3040 and +XT:3042 configure alert and threshold settings
9) +XT:7008, saves device configuration to permanent memory. You may configure
individual features and the 7008 command will save all the configuration state at that
instance.
4.3 Configuring the Device via PC
1) A RS-232 to USB TTL converter cable is required to connect a XT-4550 device to a
computer for local configuration. Connect the XT4971A Tx wire to the TTL converter
cable Rx wire. Connect the XT4971A Rx wire to the TTL converter cable Tx wire. Connect
the XT4971A ground wire to the ground wire of the TTL converter cable. Use a terminal
application to connect to the COM port associated with the TTL converter cable.
2) Use the following terminal application settings:
a. Bits per second: 115200
b. Data bits: 8
c. Parity: None
d. Stop bits: 1
e. Flow control: None
3) Press enter 3 times to activate the Aux Port. The print “Aux Port Active” will show up on
your terminal console when activated successfully.
4) Once Aux Port is active enter the password: XIRGOTECH611
5) The terminal console will print ACCEPTED when password is input successfully.

6) You can now configure the device by sending the XT commands listed in the protocol
document of this device.
a. Command +XT:1010 configures network settings
b. Command +XT:3017 configures the sleep/wake mode for the device.
i. The factory defaults for this device is to operate in the sleep timer mode and
have a minute of wake time max. You may need to temporarily disable sleep
in order to configure the unit uninterrupted by sleep.
c. Command +XT:3040 and +XT:3042 configure alert and threshold settings
7) +XT:7008, saves device configuration to permanent memory. You may configure
individual features and the 7008 command will save all the configuration state at that
instance.
4.4 Download Over the Air (DOTA) Firmware Update Guide
This devices supports firmware updates over the air. Customers must have an FTP server and
the FTP server must be configured for active mode. The procedures for DOTA are as follows:
1) Make sure that the +XT:1010 network settings are valid and that the device is able to send
and receive data with the APN configured.
2) Configure the FTP network settings via the +XT:1004 command.
3) Check that the settings are correct by querying via the +XT:1005 command
4) Make sure the FTP server is in active mode and the correct EBF file is located in the folder
that you have set in your FTP network settings.
5) Send the unit the +XT:1006 command to initiate the OTA update. Refer to the protocol
document for the proper syntax for this command. The .ebf extension is not used in this
command. The file names are case sensitive.
6) If the device cellular network settings are compatible from the old firmware to the new
firmware, then you will receive a 1007 reply signifying the completion of the update.
Notes:
•
•
•
If are upgrade to a new firmware release and parameters have been added the original settings will be
erased. The 1000, 3000, 5000 and 7000 series settings will be reset to default. Always reference release
notes before initiating a firmware upgrade.
Disable sleep mode prior to a download
Do not download older firmware into newer devices
