Firmware and SDD Field Tool Release Notes
Version 1.48
Release Date: August 06, 2025
New Enhancements:
- One-Button Demand Reset: A streamlined process to reset the meter’s demand register—just press and go. The 1039 automatically recognizes the meter, authenticates, sends the reset command, and confirms success.
- Dual Password Capability: Supports two stored passwords per meter vendor. If the first fails, the device seamlessly tries the second—ideal for field situations with legacy or unknown credentials.
- Auto Shutoff Model: This enhanced-security version features an internal inactivity timer. After a preset idle time, the unit disables standard wake-up functionality and requires a USB connection plus physical button press to reactivate—minimizing the risk of misuse if the unit is lost or stolen.
