| Known issue: |
|
RS-232 Injection Communication Loss After Network Change -
After modifying the network configuration (e.g., switching to static IP) on the TPN-MMU, RS-232 injection over TCP communication stops working. -
Workaround: Disable the related TCP ports before performing network configuration changes.
|
|
Session Expiration Handling -
When the session management timeout expires, the application does not automatically redirect the user to the login page. Instead, the user becomes blocked.
Workaround: Manually refresh the page to be redirected to the login screen.
|
|
FastSwitchCrop and FastSwitchStretch HDCP Output Mode Error -
In FastSwitchCrop and FastSwitchStretch video processing modes, the HDCP Output Mode dropdown menu appears; however, changing its value results in an error. -
Workaround: If changing the HDCP Output Mode is required, please use FastSwitch mode.
|
|
EDID Validity Status on UCX-TPN Transmitters -
The current EDID validity status is always displayed as “Invalid” when using UCX-TPN series transmitters.
Please note that the default UCX EDID is a special EDID implementation and functions properly despite the displayed invalid status. This is a display issue only and does not affect normal operation. No functional impact on video transmission is expected.
|
|
NTP Issue with Multiple Ethernet Connections -
NTP (Network Time Protocol) does not function properly when both Ethernet connections (AV LAN (PoE) and Control LAN) are active simultaneously. -
Workaround: Set the date and time manually.
|
|
TPX Devices Appearing in Crosspoint View -
TPX devices are discoverable, configurable, and appear in the crosspoint view of the MMU.
While this may be useful for device configuration purposes, TPX devices are not intended to be used in crosspoint switching operations and their presence in the crosspoint view may cause confusion. -
Workaround: Do not add TPX devices to the active configuration if crosspoint switching is required.
|
|
Alias Disappearing After Multiple Discoveries -
In the built-in web interface, after performing multiple discovery actions, the Alias name of the endpoint device may disappear from the crosspoint table. -
Workaround: Restarting the MMU restores the alias name.
|
|
Safari 26 Compatibility Issue (Safari Bug) -
The MMU’s built-in web interface may encounter errors when accessed using Safari version 26. This issue is related to a known Apple Safari 26 browser bug. -
Workaround: Please use an alternative web browser.
|
|
IP Conflict Handling -
In case of an IP conflict, devices may become unresponsive and the conflict may not be automatically resolved. -
Workaround: Switch between static IP and DHCP settings manually to restore operation.
