The Lite-Link Interface Cable is a dedicated, optically isolated USB communication cable designed specifically for use with PowerWatch voltage disturbance loggers. It provides a safe and reliable connection between a PowerWatch device and a Windows PC running ACR EventReader software.
Because PowerWatch operates while connected directly to live electrical outlets, Lite-Link plays a critical role in maintaining user safety and protecting connected computers during configuration and data retrieval.
PowerWatch loggers are line-powered instruments, meaning they are energized directly from the monitored electrical circuit. To safely interface with a computer, Lite-Link incorporates optical isolation, eliminating any direct electrical connection between the PowerWatch device and the PC.
This isolation:
Protects the computer from voltage transients or ground potential differences
Prevents ground loops during data transfer
Ensures safe communication when PowerWatch is connected to energized circuits
Lite-Link is not interchangeable with standard USB or serial cables.
Lite-Link is required to:
Configure PowerWatch voltage, frequency, and event thresholds
Download recorded disturbance events
View and analyze data using ACR EventReader software
Generate summary and detailed event reports
Once configured, PowerWatch can operate independently without Lite-Link for long-term unattended monitoring.
The USB end connects to a standard USB port on a Windows PC
The cylindrical probe end mates with the optical interface port on the PowerWatch device
Data is transferred optically, maintaining full electrical isolation
No external power supply is required.
Compatible with all PowerWatch voltage disturbance loggers
Designed for use with ACR EventReader software
USB-A interface (Windows PCs)
First-time setup and configuration of a PowerWatch device
Periodic data download after a monitoring period
Sharing a single Lite-Link cable among multiple PowerWatch units
Replacement cable for existing PowerWatch installations
Lite-Link is a purpose-built interface cable engineered specifically for PowerWatch products. Standard USB cables or adapters will not function and should not be used.
