New Features, Improvements

  • This is a major release targeted at solving issues with fleet monitoring connection stability as well as introducing improved logging capabilities. 

    1. 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.
    2. 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.
    3. Added new logging capability to help diagnose issues.
    4. The WiFi log file has been improved.
    5. WiFi Log file names now feature time stamps.
      • Requires NTP service and internet connection.
      • If no connection, then log file names will auto increment to avoid overwriting.
    6. Wi-Fi can now be configured even when connected to a wired network and even if the cart cannot communicate with the codec.
      1.  This means that the CA750 Vidyo cart can now be configured for a wireless network without requiring a wired network first or using a keyboard to bypass the Vidyo warning regarding not having a network connection. 
      2. 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 should now be more stable.
    • Several network/fleet 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

  • Sometimes, a shutdown command (issued from fleet or on the cart using theHome.png [HOME] and end_call.png [END CALL] button press) will fail to properly shutdown the cart.
    • The codec will be shutoff but the cart will not fully power off. The only way to fix this is to do a hard reset of the cart using the pinhole.
    • For now, it is not recommended to use the fleet shutdown until this issue is fixed. A fix will be implemented in the next release of firmware. Please contact support if you run into this issue as it may still be possible to remotely recover the device.
  • All time stamps (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_V_V3.01.bin will update the first number
      • “CA750 version: 3.01 / 3.01”
    • The TM4C_FW_V_V3.00.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. 


This is an EXAMPLE of the status message showing an older version number of firmware. You can get this status display by holding down the Home.png [HOME] and Auxilary.png [AUXILIARY] buttons (top right and top left of the console).
