Connecting EPR Mode-Enabled Devices to Analyzer Ports

NOTE: Applicable to Voyager M310C/M310P/M4x and Mercury T2C/T2P ONLY.

USB Protocol Suite version 8.60 and later includes a feature to protect legacy analyzers (Voyager M310C/M310P/M4x and Mercury T2C/T2P) from any damage that could be caused by the extended voltage range (> 20 V) introduced in PD 3.1. The Software will monitor the PD negotiation and break the connection when EPR Mode is entered to protect the analyzer.

When breaking the PD negotiation, the software displays a warning message as shownbelow. This warning message continues to prompt until the devices connected to the analyzer port are physically disconnected.

If a recording is in progress, the captured trace will include a specific event called “Unsupported EPR Entry” and show the sequence for breaking the connection.

Breaking the EPR Link in analyzer Platforms without EPR Mode

NOTE: For EPR testing, consider the Voyager M310e. It provides full support of PD 3.1 and the expanded voltage range, up to 51 V.

WARNING: Any downgrade of software to a version lower than 8.60 is not recommended.
