XD-502 Gen 2.5 | Major Software & Firmware Overhaul

Big news for stack testers: The XD-502 Gen 2 just leveled up to Gen 2.5.

We’ve rolled out a major software and firmware overhaul designed to streamline your workflow on the sampling platform. Whether you want direct browser control from your device or smoother data offloading.

What’s new:

• Browser-Based Control: Built directly on the onboard ESP32, the software interface is now fully wireless. Connect instantly from any web browser on your phone, tablet, or laptop—no specialized apps required.

• Quick-Swappable Pressure Transducers and Vacuum Sensor: Now all consoles include user-replaceable pressure transducer and vacuum sensors. Sensors can be replaced instantly in the field with pre-calibrated and ready-to-go replacements.

• Instant Data Export: Download test runs directly through your browser with immediate file retrieval, plus enhanced USB transfer reliability in the field.

• Refined Menus & Settings: Enjoy cleaner configuration screens, more consistent on-screen menu behavior, and more efficient connection handling. The Save Data button will now always confirm any changes within the console’s menu. No more wondering what sequence needed to be done to confirm your changes. Also, a new run status update line has been added to the Status (3rd main screen) on the console’s LCD screen allowing you to easily keep tabs on your run number, point number, remaining number of points, and remaining traverse time (if applicable).

How to upgrade:

Every existing XD-502 Gen 2 console is fully compatible. You can upgrade to the new software & firmware in minutes using a straightforward software flashing tool, or by dropping in a pre-flashed replacement ESP32 board.
