TOPCON OPUS series for commercial vehicles
The perfect interface between vehicle technology and precise control tasks
The integration of intelligent control units is a key task in modern vehicle development. The trouble-free implementation of suitable control devices is becoming increasingly important, particularly in mobile machinery, construction and agricultural machinery. Nowadays, vehicles in these sectors are more than just a tool for making work easier. They are high-performance vehicles with increasing intelligence.
In this context, TOPCON has established itself as a strong partner for HMI solutions and devices, particularly for miunske as a system supplier and system integrator. But what exactly does system integration from miunske mean?
TOPCON OPUS devices in miunske portfolio
Various variants for different application scenarios in vehicles
The portfolio of the TOPCON Opus series takes into account the numerous possible applications of the control units in customer-specific vehicle concepts. miunske® has a broad portfolio of different operating devices from the Topcon Opus series, which can be programmed for customized applications.
Neben den kompakten und robusten Steuergeräten der Serien OPUS A3e und Opus A6e gehören zu diesen Serien auch die funktional erweiterten Steuergeräte der Serien Opus A3s und Opus A6s. Compared to the e-series, the s-Variants are not only characterized by a larger and clearer display, they also have an encoder and additional hard and soft keys, which enables the implementation of multiple control tasks.
Opus B series operating devices are suitable for challenging applications. Depending on the version, customers receive a powerful control device with a touchscreen in a sleek design and, depending on the version, with additional function buttons.
miunske offers an overview of common variants such as Opus A3, A6, A8 B3, B4 and B6 in its online catalog. Customers can find all information there and have the opportunity to compare the products in terms of performance, display size, protection classes and other technical details.
Technical interfaces enable a wide range of functions in vehicle integration
CAN interface
TOPCON Opus devices support the common CAN bus protocols, such as CAN open SAR J1939, which can be used to control machine functions, evaluate operating data and transmit commands.
ISOBUS interface
Some OPUS devices can operate as a virtual terminal and have an ISOBUS interface that conforms to the ISO 11783 standard. This makes it possible to manage different devices, even from different manufacturers, on one display.
Input/Output
Devices of the TOPCON OPUS series have a large number of direct inputs and outputs. These can be either digital (high/low signals) or analog and enable the direct connection of buttons, joysticks, sensors or actuators - without the need for additional control devices.
additional interfaces
Depending on the model and version, additional interfaces such as Ethernet, USB, RS-232/RS-485 are available for:
- firmware updates
- Communication with external control systems or sensors
- Connection to telematics systems or cameras via Ethernet
The TOPCON product sheet provides an overview of TOPCON operating devices of the OPUS series as well as technical details.

miunske-reliable partner with know-how in system integration of TOPCON devices
For many OEMs and vehicle manufacturers, the system integration of TOPCON Opus devices into the existing vehicle network is a challenging task – both in terms of communication architecture and software development. As an experienced development partner and system supplier, miunske provides support throughout the entire integration chain. miunske® takes care of the design of the HMI interface, the parameterization of the interfaces and the integration into existing control concepts.
In operation - OPUS Geräte in der Landtechnik, Baumaschinen und Sonderfahrzeugen
TOPCON Opus operating devices from the miunske portfolio are used in a wide range of mobile machinery, commercial and special vehicles. The reason is that they are flexibly programmable, reliable and robust. Further the devices are also suitable for applications with high requirements in terms of EMC, temperature resistance, mechanical load capacity and protection against dust and moisture.
Precise operation and control in the agricultural sector
Variants of the Topcon Opus devices can be used as ISOBUS-compatible terminals in agricultural machinery such as tractors, combine harvesters, sprayers or balers. Here, for example, they serve as operating and monitoring instruments for controlling the continuously variable transmission in tractors, the harvesting speed and corresponding vehicle data. Used in spraying machines, they can be used to apply the exact quantity of spray agent and record the data, as well as in balers to check the hay bale size and the status of the available binding materials and films. In addition, camera images, application maps and GNSS data can be integrated into the operating concept.
Central control unit for variable use
In construction machinery such as excavators, wheel loaders and crane trucks, Topcon control devices have proven their worth, particularly for controlling hydraulic functions and monitoring functional vehicle units. The integration of the devices not only significantly simplifies the operation of heavy and complex machines in particular, but also significantly increases the safety of the machinist operator during vehicle operation.
HMI solutions for hydraulic control and machine guidance
In the field of municipal and special vehicles – such as road sweepers, winter service vehicles or fire engines – Opus devices are often the central operating and display unit. Functions such as automatic spreading, water pump control or diagnostic interfaces can be displayed in a user-friendly and clear manner – even for changing operating personnel and adaptive modules.
Mobile and flexible integration of TOPCON devices in commercial vehicles
Mobile industrial applications, e.g. cranes, heavy-duty transporters or special vehicles in the logistics environment, also benefit from the flexibility of the Opus platform. Control of complex motion sequences, safety functions such as emergency stops or the integration of external sensors can be easily implemented.
