We take great pride in our scientific design approach, embracing real world echo and simulation.
Our advanced working knowledge and understanding of the NMEA standards has enabled us to hone and perfect our agritech product designs.
Our agritech product range is held in high regard throughout the Agricultural industry by offering real solutions to your ISOBUS communications issues whilst holding quality, durability and unrivalled sophistication at its heart
In simple terms it’s about compatibility, connecting all vehicle implements and machinery so they can talk amongst one another. Compatibility is (and remains) one of the biggest bugbears in the Agricultural industry.
ISOBUS is a reference term that identifies ISO 11783, a worldwide standard covering all aspects of an integrated tractor and implement communication system
ISO simply means “International Standards Organisation” whereas “BUS” is a way of transferring data known as Binary Unit System?
ISO 11783 is a communication network standard defined by the International Standards Organisation for agricultural and forestry vehicles
No, CAN Bus ‘Controller Area Network’ (Designed by Bosch) defines the Physical Layer i.e. wires, cables, connectors etc, and the Data Link Layer – how to move data from A to B. ISOBUS is one of the J1939 derivatives and is dedicated to implementing communication in agriculture & similar type vehicles. (J1939 is another network standard developed for automotive applications, and ISOBUS is developed using the technology defined in this standard)
CANBUS is a harness that runs from the front of the vehicle to the rear. All controllers on the vehicle can talk to one another using this CANBUS system. Controllers may include the engine controller, hydraulic controller, and transmission controller.
ISOBUS or ISO 11783 standard provides a framework for manufacturer’s agricultural vehicles to create data networks in a common format. It includes things like the specification of cables, plugs and sockets, inclusive of sensing, control and display software.
The majority of AG equipment today are ISOBUS-ready meaning you can plug them directly into your vehicle through a 9 pin ISOBUS plug, for example: planting equipment, sprayers, balers. One ISOBUS terminal can operate them all although some vehicles have more than one plug to help with equipment both front and back.
ISOBUS makes this easy! Because one terminal can operate multiple implements you can simply toggle between them on the same terminal. Once an ISOBUS ready terminal is plugged in it will automatically be detected and displayed
New tractors will almost certainly have an ISOBUS socket available, older tractors can be fitted with a universal terminal which will require some wiring. It all depends on the what data you wish to get out of your tractor. If you want to know what your sprayers, planters, balers are doing inclusive of things like moisture sensors then it’s useful to have ISOBUS available but there are further implements that don’t necessarily connect to ISOBUS
You may also wish to connect things like cameras or GPS. Global positioning systems help tremendously with things like steering guidance, variable rate applications and section control. Although cameras can be wired in, you’ll find that GPS systems use a set of standards called NMEA.
NMEA is short for National Marine Electronics Association. NMEA defines standard data formats supported by all GPS manufacturers, much like ASCII is the standard for digital computer characters in the computer world. NMEA data can be transmitted via different types of communications interfaces such as RS-232, USB, Deutsch connectors, Bluetooth, Wi-Fi, UHF, and many others. Two types of NMEA standard are available, NMEA 0183 and NMEA 2000. NMEA 0183 is an old serial bus standard dating back to the 1980s. NMEA 2000 is new standard, which, like ISOBUS is also developed using J1939/CANBus core technology.
NMEA 2000, as well as being used in Marine is also used internationally for agriculture due to its compatibility with J1939. GPS-based applications in precision farming are being used for farm planning, field mapping, soil sampling, tractor guidance, crop scouting, variable rate applications, and yield mapping. However, many GPS systems use the older NMEA 0183 standard, which means these systems can’t communicate on the ISOBUS. To do this, you’ll need a convertor that converts from NMEA 0183 to NMEA2000 – this is where Actisense come into play

Not really, there are differences between the two. The main differences are as follows:
NMEA 0183 – This is a single talker meaning it only communicates one way with multiple devices listening and predates NMEA 2000.
NMEA 2000 – Is essentially the Big Brother of NMEA 0183. It both talks and listens to multiple devices and can have a whole host of conversations back and forth simultaneously. It is based on the same CAN Bus standard as ISOBUS, so in most cases, can co-exist.
You have a few options, Climate-Corp’s display ‘ClimateFieldView’ uses our NGW-1 for example. It enables your GPS to connect all farming implements, enabling data to be collected and displayed such as planting population, singulation, spray rates & harvest rates whilst producing geospatial maps.
Actisense are able to offer custom cable assemblies for all types of Agricultural use. Ranging from the most simple BNC flylead through to specific ISOBUS 9 pin, Deutsch & RS232 connectors. We have specialist teams in place dedicated to the Agritech industry that enables us to supply looms and harnesses to customer specifications.
