Modular Telematics Gateway Theory of
Operation
Modular telematics gateway (MTG) is one of the main
components that enable John Deere telematics solutions,
including JDLink™. MTG is a controller that contains
firmware, a cellular modem, and a subscriber identification
module (SIM) device. MTG transfers data to and from the
JDLink™ host server over a cellular network. MTG also
contains a wireless modem that is used to transfer data
when connected to a wireless network.
JDLink™ requires the purchase of appropriate hardware
and a JDLink™ subscription. When MTG is powered on
by machine for the first time, it registers with JDLink™
host server and receives the authorization to report data.
MTG Communication
MTG sends and receives data and messages over cellular
or wireless networks. MTG supports other telematics
solutions, including Service ADVISOR™ Remote, John
Deere Remote Display Access, John Deere Wireless Data
Transfer, and John Deere Machine Sync shared data.
Telematics solution applications, such as Remote Display
Access, require an uninterrupted cellular connection to
function. Other telematics solution applications, such as
Wireless Data Transfer and Machine Sync shared data,
store information on the display and transmit data when
a cellular connection is established. Telematics solutions
such as JDLink™ do not require an uninterrupted cellular
connection because MTG can store machine data for up
to 1000 hours. When MTG returns to an area of cellular
coverage, the most recent 1000 hr. of data are forwarded
to the host server at its next scheduled time.
When powering down machine, MTG remains powered
for the time needed for functions to complete. MTG
enters a sleep state for up to 7 days. During sleep state,
MTG calls in during its scheduled times. When JDLink™
curfews and geofence alerts are set, MTG checks for any
changes in its environment. After sleep state, MTG enters
a hibernation state and is not able to send or receive data.
The only way to wake MTG from hibernation state is to
turn key switch on and power up machine.
Machine Sync Shared Data Capabilities
MTG supports machine to machine communication.
Utilizing a Machine Sync activation, displays can share
data, such as coverage maps and guidance lines,
between multiple machines.
Remote Service Capabilities
MTG supports remote service capabilities. Service
ADVISOR™ Remote is a tool for a dealer technician to
service other machine controllers using the MTG. Operator
accepts the download and installation procedures. MTG
controller receives firmware updates remotely from John
Deere that do not require operator or dealer intervention.
Website
Data sent by MTG is made available to registered users
using password-secured JDLink™ website. Notifications
are sent to users through e-mail or SMS text messaging.
Dealer must log in to transfer MTG to new customer
account.
View current and historical status of equipment on
JDLink™ website. Information is collected, such as
location, machine hours, idle time, maintenance intervals,
and other machine settings. Use website to send a
request to MTG to view real-time status of a machine.
Wireless Network
Wireless modem within MTG allows communication to
local networks (such as other machines, mobile devices,
and computers), and local access points (such as a home
or shop network). MTG can send and receive data and
messages over a wireless network the same as over a
cellular network.
Bluetooth®
Bluetooth® wireless technology enables connectivity
to mobile devices, such as a smartphone or tablet, for
wireless network configuration and information viewing on
machines without supported on-board displays.
SolutionsPlus App
NOTE: When making a wireless connection from
machine to local network, individual data rates
from that network may apply.
SolutionsPlus app for Apple® and Android™ devices
configures wireless network for the machine’s MTG.
SolutionsPlus is required to connect machine to local
wireless network. SolutionsPlus is available through the
John Deere App Center.
To connect mobile device to machine, mobile device must
be within 12.2 m (40 ft) of machine cab and key switch
must be on while engine is off.
After turning key switch to Run, it takes about 1 min
for Bluetooth® to become active. Once Bluetooth® on
MTG is active, it is available for 10 minutes. Only one
mobile device can connect to a machine at a time over
Bluetooth® connection.
