Psa Xs Evolution 9780.z5 | Driver
Once installed, the device should appear under Ports (COM & LPT) as "PSA XS Evolution Virtual COM Port (COMx)". Note the COM number for your control software (e.g., LabVIEW, Python script, or PSA Configurator Tool).
Most PSA XS Evolution units connect via a USB-B or micro-USB port for configuration. Upon connecting, the PC recognizes it as a generic CDC (Communications Device Class) or a proprietary vendor interface. Without the correct .inf and .sys files, Windows will flag it as an "Unknown Device."
Typical error code: Code 28 – The drivers for this device are not installed.
If you have plugged the device in and it is not being recognized, follow these steps:
Cause: IRQ conflict or outdated firmware on the PSA unit itself. Solution: Psa Xs Evolution 9780.z5 Driver

The "Psa" prefix typically refers to Precision Systems & Automation, a now-discontinued European brand known for high-torque stepper and servo drivers. The "Xs Evolution" line was their mid-2000s flagship series, designed for synchronized multi-axis motion.
The 9780.z5 is a specific firmware and hardware revision. The ".z5" suffix indicates a customized OEM version, likely built for a specific industrial partner (possibly in semiconductor manufacturing or medical imaging). Unlike generic drivers, the 9780.z5 uses a proprietary command set and a physical interface that differs from standard RS-485 or CANopen.
A small but dedicated community has reverse-engineered the protocol. Using a Lattice ICE40 FPGA and an Arduino Due, they created a Protocol Translator Box that sits between a standard Modbus RTU driver and the 9780.z5’s physical interface. This allows you to replace the original host PC with a modern Raspberry Pi running LinuxCNC. Once installed, the device should appear under Ports
The PSA XS Evolution 9780.Z5 is a professional-grade vehicle communication interface (VCI) used primarily for Peugeot and Citroën (PSA) diagnostics. While it is highly capable, its performance and compatibility depend heavily on whether you are using a genuine unit or a "clone" and the specific driver/software version installed. Core Functionality & Capability
Comprehensive Diagnostics: Unlike universal OBD-II scanners, this interface performs nearly all dealer-level functions, including reading/clearing fault codes, displaying real-time data, and executing actuator tests.
Advanced Operations: Supports telecoding, module adaptations, and system resets. However, manual telecoding is often restricted in newer Diagbox versions (V9 and above) compared to older versions like V7.58.
Protocol Support: Built with a K-Line multiplexor and supports CAN-BUS and SAE J1850 protocols. Driver & Software Compatibility Most PSA XS Evolution units connect via a
Operating Systems: Drivers typically work best on Windows 7 (32-bit) for older software versions. Modern versions (V9.85+) can run on Windows 10 and 11, but often require a Virtual Machine (VM) to ensure stability and compatibility.
Driver Variants: In Device Manager, the interface may appear with two driver types: UMDF or Multi-instance. Users often find the "Multi-instance" driver more stable for specific clones.
Interface Checker: A vital utility for these drivers is the PSA Interface Checker, which identifies the hardware's serial number and firmware version (e.g., V4.2.4). Critical Technical Considerations Feature Professional Insight Genuine vs. Clone
Genuine units feature a silver nameplate. Many clones are "blacklisted" by newer software if their serial number ends in /B, requiring a hardware reflash to work above Diagbox 5.29. Firmware Version
For optimal compatibility with standard Lexia/PP2000 software, firmware should generally not exceed V4.2.4. Connectivity
Cable quality is a common failure point. The shorter USB cables often provide more reliable recognition than the longer ones included in many kits. Common Troubleshooting PSA XS Evo driver help | Peugeot Forums
