Claas 7 pin, diagnostics cable

Jaltest JDC529A9 - Claas 7-Pin Diagnostics Cable

The Jaltest JDC529A9 is a genuine Cojali 7-pin diagnostic cable for Claas agricultural equipment. Claas uses multiple connector configurations across its tractor, combine harvester, and forage harvester product lines — and the 7-pin port is one configuration found on certain Claas machines. This cable is the correct interface between the Jaltest Link V9 and Claas equipment equipped with a 7-pin diagnostic connector. If you are running Jaltest AGV and working on Claas machines, this cable covers the 7-pin variant that the JDC519A and JDC525A do not.

What This Cable Does

The JDC529A9 connects the Jaltest Link interface to the 7-pin diagnostic port on Claas equipment. Once connected, the Jaltest AGV software communicates with the machine's ECUs, providing fault code access, live data, and calibration capabilities for supported systems.

Claas Connector Landscape — Which Cable Do You Need?

Claas is a prolific manufacturer with decades of equipment in the field, and they have used a range of diagnostic connector configurations. The Jaltest cable lineup covers several Claas variants:

• JDC519A — Claas and Renault (standard connector)
• JDC525A — Claas and Renault 14-pin
• JDC529A9 — Claas 7-pin (this cable)
• JDC530A9 — Claas 8-pin

Shops servicing mixed Claas fleets — particularly those working on older and newer models side by side — may need multiple cables to cover the full range. The 7-pin connector found on certain Claas models requires this specific JDC529A9; using the wrong cable will result in no communication.
