JDLink™ M Modem

The JDLink M Modem is the device that connects your machine to internet, transferring the collected information to Operations Center™. The internet connection is established by 4G, 3G or 2G, as coverage availability, also can be connected by Wi-Fi. This modem is simple to install as it has a universal harness that is connected to machine’s ISO bus port and doesn't need an external antenna as it has an internal one. M Modem has almost the same capabilities that R Modem has with the exception of machine sync. 

Machine Data
M Modem is ideal for all machines that uses the ISO bus architecture and SAE- J1939 protocol: 
• Commercial Z9 Mowers
• Gators
• Non-Deere machines in general
• Vehicles
• Deere legacy machines (before 2012)

The M Modem can also be connected to machines without CAN bus, with focus on machine position, machine speed and machine hours.

For non-Deere machines, all data collection is made by the messages that are transmitted by CAN bus messages, following the protocol SAE-J1939. Following is the main information that may be capture by the modem. This information may change by manufacturer, model, and model year:
• Engine speed [rpm]
• Engine load [%]
• Wheel speed
• Fuel level [%]
• Fuel consumed [l]
• Fuel rate [l/h]
• DEF level [%]
• Rear PTO (On/Off)
• Front PTO (On/Off)
• Coolant temp [oC]
• Machine hour [h]
• AutoTrac Utilization (On/Off) – only for competitivity tractors
• DTC Alerts (J1939-71) – only for competitivity tractors

For Deere legacy machines all available information will be captured through the machine CAN bus. Tractors and STS 70 series are following the same previous list for non-Deere machines, including machine state (working, idle and transport).

Information that comes from the modem, independent of CAN bus messaging is:
• Location
• GPS speed [mph-km/h]
• Machine hour [h]

Agronomic Data and RDA
Agronomic data will be available when a John Deere Display is used together with the modem. When using the G5 Display model, the connection is directly using the universal harness. When using a 2630 or Gen4 display, it is necessary the use of ethernet switch kit. Ethernet Switch Kit will be available later in the year 2023.
