8 3.3 Trailer Cradle Mounting An optional trailer mounting cradle can be purchased for easy device mounting for the XT4975A. The cradle will need to be screw-mounted or VHB Tape mounted to the position desired. The XT4975A 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. Inside the body of the cradle where the device sits are four drain holes. Do not use the drain holes for screw mounting cradles to surfaces. DRAIN HOLES 3.4 Container Cradle Mounting An optional container cradle can be purchased for easy device mounting for the XT4975A. The container cradle is designed for VHB Tape mounting only. The XT4975A 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. Inside the body of the cradle where the device sits are four drain holes. Do not use the drain holes for screw mounting cradles to surfaces. DRAIN HOLES 9 3.5 Device Mounting Guidelines The XT4975A 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 XT4975A 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 XT4975A:
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 XT4975A 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 XT4975A 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 XT4975A 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) 10 The XT4975A must be mounted flush to a flat surface. Failing to mount the XT4975A to a flat surface can lead to excessive strain on the top plate which can compromise the device environmental seal and allow ingress of dust and water. When screw mounted, it is recommended that the device is mounted with size #10-24 mechanical bolts and 5.5-6.0 lb.in torque be used. Failure to use the correct bolt size or to apply the correct torque can result in damaging the mounting bracket. Do not attempt to drill out the mounting hole to accept a larger bolt than specified as this will also damage the bracket. When using a drill to screw mount the device, ensure the drill has clearance from the top plate and does not come in contact with the top plate during installation. Damage to the top plate from installation can compromise the device environmental seal and allow ingress of dust and water. Please refer to the image below:
A small black button (Wake-up button) is located on top of one of the mounting holes. When screw mounting the device it is important to be aware and stay clear of this button as it can be damaged during the installation when not minded. Damaging this button or permanently engaging the button will affect the device functionality. 11 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. 12 4.2 Configuring the Device via SMS 1) Ensure your device is active on your cellular account. 2) Awaken device from sleep XT4975A via the wake-up button. 3) If the device needs more power, then supply 12V DC via the red wire of the cable harness. 4) Ensure device cellular LED is blinking based on LED definition in this document. 5) Using your mobile phone or SMS gateway send +XT:1008 command to the device MDN 6) Command: +XT:1008,<SM>- Sets SMS Number 7) Response (via SMS): $$<UID>,<1008>,<SM>##
8) 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,<PF> 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 the XT4975A to a computer for local configuration. Connect the XT4975A Tx wire to the TTL converter cable Rx wire. Connect the XT4975A Rx wire to the TTL converter cable Tx wire. Connect the XT4975A 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 login to the device using the AES challenge prompt. Please contact your Xirgo FAE to get instructions on how to complete this process. 5) The terminal console will print Accepted when successfully completed challenge prompt. 13 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,<PF> 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 14 Regulatory Statements FCC:
