The Jaltest (JDC540A) is an Adapter Cable specifically designed to connect a Jaltest diagnostic interface with the diagnostic port of Bosch Rexroth systems. The cable features an 8-pin R232 connector for the vehicle side and a 16-pin OBD2 connector for the diagnostic interface.
This cable enables communication with the control units (ECUs) of Bosch Rexroth, which are often used in work equipment, agricultural vehicles, and industrial machines. This allows technicians to perform tasks such as reading fault codes, monitoring live data, and carrying out system-specific calibrations and configurations.
Application and functionality:
This diagnostic cable is developed to establish a stable and reliable connection between a Jaltest diagnostic device and a Bosch Rexroth control system.
- Control unit diagnostics: Enables reading and clearing fault codes (DTCs), and retrieving system information from the Bosch Rexroth ECU.
- Live data monitoring: Provides access to real-time sensor data and system parameters, helping analyze system operation.
- System configuration and calibration: Supports adjusting parameters and performing calibrations on compatible Bosch Rexroth components.
Compatible vehicles and applications:
This Adapter Cable is not specific to a single vehicle brand but is intended for diagnostics on Bosch Rexroth systems equipped with the 8-pin R232 diagnostic connector. These systems are found in a wide range of applications.
- Agricultural vehicles: Tractors, harvesters, and other agricultural machinery.
- Construction and earthmoving machines: Excavators, loaders, cranes, and bulldozers.
- Industrial installations: Machines using Bosch Rexroth hydraulic and electronic controls.
Important: Before purchasing the product, always check your vehicle’s connector. This may vary by model and year of manufacture.
