MXCWAPT - Access Point

Improvements

• Support for new MXCWAPT hardware components
• Bug fixes

Known Issues

MXCWAPT

• MXCWAPT FW update with older versions of SUU may result in SUU reporting a false update failure, when update was actually successful.  If this occurs, verify FW on APT via GUI or LCD.
• When downgrading from FW 7.0, to FW4 or lower, the process has to be done in two separate steps: First upload the MXCW640 FW to the APT via the SUU and downgrade the discussion units. Secondly downgrade the MXCWAPT from SUU.

MXCWAPT Component GUI

• When running Windows-Version:1809, cannot access APT CGUI when opened via DNS Name applied directly to the browser search bar or with Shure Web Device Discovery Application shortcut. Opening APT CGUI via IP address works as designed.

MXCW640

• MXCW640 Left/Right buttons incorrect LED indication when using FIFO conference mode with Dual-Delegate or while identifying units while in Request List.
• In very rare occasions, MXCW640 touch screen will not respond to screen touch.  Resolved by power cycling unit.

TPCI

• Once MXCW640s are set to Ambient Role, unit will no longer respond to TPCI strings that are indexed based off of seat number.
• Once MXCW640s are set to Ambient Role, and rebooted, unit will no longer send TPCI strings when changing role to other than Ambient (Chairman, Delegate, Interpreter etc). Resolved by power cycling the unit, while not in Ambient role.
• Rare TPCI errors reporting a single MXCW640’s when transitioning roles from Ambient. Resolved by restarting unit.

Software
