New Features, Improvements

  • This is a major release targeting exciting new features, stabilizing fleet monitoring connections, and introducing improved logging capabilities. 

    1. Enhanced Far End Camera Control Support Added.
      • Avizia is proud to announce the release of our Enhanced Far End Camera Control (FECC) feature. This new feature allows a user to point and click on their screen to control the PTZ camera on the cart.
        • This is only supported when calling via the Avizia v10 software platform.
        • Please contact your sales representative to find out more.
    2. The cart will now always turn on by default after a power cycle or boot up from shutdown state. 
      • Previous behavior: the user was required to push the power button to start the boot up process.
      • New behavior: Upon power on, reboot or pin-hole reset, the cart will always automatically turn on.
    3. Updated to the latest firmware OS and SSL versions to include the latest security and stability patches.
      • This provides up to date security for the SSL used for fleet monitoring.
    4. Added new logging capability to help diagnose issues.
    5. The WiFi log file has been improved.
      • WiFi Log file names now feature time stamps.
        • Requires Network Time Protocol (NTP) service and internet connection.
      • If no connection, then log file names will auto increment to avoid overwriting.
    6. The power LED will now turn off on the CA750C when put into standby, even if Do Not Disturb mode is disabled.
      • Please note, regardless of the Do Not Disturb mode, the only way to wake up the cart is to press the power button. (An incoming call can also wake and activate the cart if DND is disabled.)
    7. Wi-Fi can now be configured even when connected to a wired network and even if the cart cannot communicate with the codec.
      • Configuring WiFi while the cart is plugged into Ethernet is not recommended as the radios will not connect or display connectivity messages until the Ethernet is unplugged.

Please refer to Avizia web site for the Avizia Configuration and User Guide and Firmware Upgrade Instructions on the CA750.

Fixed Issues

  • If Network Time Protocol (NTP) service fails for any reason, the cart CPU will still be able to connect to the fleet service.
    • NTP service allows the cart CPU to keep time and is useful for time-stamping log files and messages as well as for dating fleet communications.
    • Accurate time also allows additional SSL security validation steps to be completed. Where possible, it is recommended to use NTP. However, the fall back option is still fully encrypted and safe to use.
    • The current firmware uses a fixed public NTP server which is on port 123.
  • Fleet service stability has been increased.
    • Several network related bugs were found and have been fixed in this release.
    • Customers who previously experienced fleet service issues where a cart would fall offline after an extended period of time are highly encouraged to use the flash drive logging method to help diagnose any issues that continue to occur with this release of firmware.
  • The fleet service will now display the codec in an “unregistered” state if the cart controller/CPU loses the serial communication with the codec.
  • Fixed an issue where sometimes user messages could be intermittently missed and would not display properly.

Known Issues

  • All timestamps (primarily used for log files) are currently shown in EST. A future firmware revision will add support for configuring and/or detecting time zones.
  • File modification times on the flash drive for log files created by the CPU are invalid. The time stamps in the name will be accurate but are in EST.
  • Occasionally, the Wi-Fi configuration will not fully configure the radios. This issue existed in previous firmware revisions. A fix is currently in work.
    • Reconfiguring the Wi-Fi on the cart should resolve this. 
  • The warning message that displays when configuring Wi-Fi with the wired ethernet still attached to the cart is not displayed for a long enough time. This will be fixed in the next firmware revision.
  • Occasionally, an attached USB drive will fail to be detected. This typically happens after unplugging and plugging it in multiple times. A reboot of the cart is required to fix this. A fix is being investigated.

Firmware Upgrade Process

  • Please refer to the CA750 Firmware Upgrade Instructions article and video. 
  • There are two components which need to be upgraded. This is reflected in the “CA750 version” section.
    • The PW338_FW_V3.01.bin will update the first number
      • “CA750 version: 3.01 / 3.01”
    • The TM4C_FW_V3.01.bin will update the second number
      • “CA750 version: 3.01 / 3.01

NOTE: If updating from 3.00 to 3.01, the cart will now only reboot ONE time. This will be the default behavior going forward.
