Curtis diagnostics cable

Jaltest JDC566.9 — Curtis Diagnostics Cable

The JDC566.9 is a genuine Cojali Jaltest diagnostic cable engineered to connect Curtis electric motor controllers to the Jaltest diagnostic platform. Curtis is one of the most widely used motor controller brands in electric forklifts, pallet jacks, and other electric material handling equipment — and getting reliable diagnostic communication with Curtis controllers requires the right physical cable.

Listed in the official Jaltest 2025 pricelist at $180 MSRP, this cable complements the Jaltest MHE (Material Handling Equipment) software license. If your shop services electric forklifts or warehouse equipment running Curtis controllers, you need this cable to access fault codes, live data, and controller parameters through Jaltest.

What This Cable Does

Connected between your Jaltest Link V9 interface and the Curtis controller diagnostic port, the JDC566.9 enables:

• Fault code reading and clearing on Curtis electric motor controllers
• Live data monitoring — motor speed, current draw, temperature, voltage, and controller status
• Parameter viewing within Jaltest MHE software coverage
• Controller diagnostics for electric drive systems in forklifts, reach trucks, and pallet jacks

Important: Requires JDC100 Extension Cable

The JDC566.9 requires the JDC100 Extension Cable (SUBD-26 + Jack) for use with the Jaltest Link V9. If you do not already have the JDC100 in your kit, you will need to add it. The JDC100 is available separately for $100 MSRP and is a common component in multi-cable MHE setups.

Compatible Equipment

• Curtis electric motor controllers — widely used in electric forklifts (sit-down, stand-up, reach), electric pallet jacks, and order pickers
• Common in equipment from Yale, Hyster, Toyota, Crown, Raymond, and others that use Curtis controllers
