Version 5.2.2

Release Date: 6/13/2018

New Feature

• AES67 support on MXW Access Points (MXWAPT) and MXW Audio Network Interfaces (MXWANI)

Improvements

• Notifications added to the MXW control software to inform you when a firmware update via Shure Update Utility is recommended.

Bug Fixes

• For MXW installations across multiple subnets managed by SystemOn, MXWNCS chargers discover only four microphones on the MXWNCS8 charger even though there are more than four.
• MXW Control Software doesn't show an "Unlink" button on the Monitor tab when microphones are powered off or out of range, or when networked chargers are offline.
• Microphones already linked to an Access Point can't link to a different Access Point without first unlinking.
• After microphones are removed from a charger, active microphones take several minutes to appear on SystemOn and trigger false notifications.
• Status update stops on the Scanning Session display when changes are made to the Channel Density mode (Standard to High, or High to Standard) or to the RF Coordination mode (A to B, or B to A) during a spectrum scan.
• MXWAPT firmware updates may fail after repeated attempts using the Shure Update Utility.
  • Note: Please contact Shure Support to replace an affected MXWAPT.
• Due to factory programming error, MXWAPT4 and MXWAPT2 access points shipped from October 2017 through March 2018 may incur frequent erratic microphone behavior indicated by a constant red blinking LED on the microphones, even when the microphones are well within range of the access point.
• During Spectrum Scan, modifying MXWAPT configuration settings can put the device in a non-deterministic state. If configuration settings are modified during Spectrum Scan, MXWAPT must be rebooted.

Known Issues

• When an interfering DECT device is transmitting nearby an MXWAPT, the Access Point may occasionally drop the connection to mics 1-4. To recover mic connectivity, you can reset the MXWAPT. Examples of interfering DECT devices are other MXWAPT devices that are not on the same subnet as the affected MXWAPT; however, in many cases, the interfering DECT devices are wireless headsets for wired telephones on desks.
• SystemOn 3.0.1 incorrectly warns "Check system requirements, your current firmware version may not be confirmed compatible".
