USB cable to RJ-45 PC port (PC-virtual terminal Fendt)

Jaltest USB to RJ-45 Virtual Terminal Cable for Fendt (JDC500)

The JDC500 is the Cojali Jaltest Virtual Terminal Cable — a Mini USB to RJ-45 adapter that connects your PC directly to Fendt agricultural equipment via the tractor's virtual terminal port. If you work on Fendt tractors and need to access the virtual terminal (the onboard display/control network) from a laptop running Jaltest AGV software, this is the specific cable that makes that connection. At $25, it is a low-cost but required cable for this specific Fendt diagnostic workflow.

What This Cable Does

The JDC500 connects a PC (running Jaltest AGV diagnostic software) to the RJ-45 PC port on Fendt agricultural equipment. This is the virtual terminal interface — not the standard diagnostic port — and requires this specific cable to communicate properly with Jaltest software.

Fendt and the Jaltest AGV Platform

Fendt is one of the premium agricultural tractor brands covered under the Jaltest AGV system. The Jaltest AGV kit (part number 29210, $4,500 MSRP) covers all ECUs on agricultural vehicles across 140+ brands, including tractors, harvesters, and implements. Fendt-specific diagnostics within Jaltest include engine systems, transmission, hydraulics, and body computer access at dealer-level depth. The JDC506A9 (Fendt A9 diagnostics cable, $90) handles the standard diagnostic port connection; the JDC500 is the companion cable specifically for the virtual terminal interface.

Who Needs This Cable

Agricultural equipment shops, Fendt dealers, and cooperatives running Jaltest AGV who work on Fendt tractors equipped with virtual terminal ports. If your Fendt diagnostic workflow requires PC access to the virtual terminal — not just the standard diagnostic connector — the JDC500 is the required cable. It is a small, low-cost item but without it, that specific connection point is inaccessible.
