Description

Version 1.5.0 ( August, 2022) Release Notes

Security

While Telos has consistently recommended that MPX Node be run in a secure VPN environment, we are aware that some customers choose to run their units on the public Internet, leaving themselves open to probes and exploits. Changes in our latest release help harden the system against hackers and bad actors, proactively reducing risk for our users.  Security changes include: 

  • Rework to our password system
  • Login authorization required for all software endpoints
  • Removal of accounts used for demo purposes.
  • Required acceptance of our End User License Agreement (EULA).
Stability 

Support has seen a couple rare cases where the GUI may become inaccessible (even while the product continues to pass MPX signal), requiring a remote session from Telos support, or a power cycle to clear it.  Stability upgrades include: 

  • Upgraded log rotation, preventing logs from taking too much storage
  • Internal service failure detection and automatic restart.  
New User Features
  • More granular settings for MPX level output and uMPX Delay settings
  • Finer resolution mouse wheel control support of all sliders

Preparing to update

If you are updating from a very early version such as 1.1.5,  updating may clear some settings on the MPX Node. Before you update, write down existing settings or take screen shots of Setup pages and associated tabs, just in case a setting gets overwritten. 

Download the Update File

Version 1.5.0 can only be installed on units running version 1.3.37 or higher. 

If your MPX Node is running any lower version of software (1.3.35 or below) you must install version 1.3.37 first before installing 1.5.0. This intermediate step installs support for our latest software updater. 

Save the update files to a convenient location on your computer.


Installing the Update

A cautionary note about remote updates. While updating via remote is more convenient than driving to the transmitter, there is always a risk when updating by remote since you aren’t standing right in front of the unit. In the event you need perform a hard power cycle or your unit, be ready with a contingency plan, just in case!

The MPX Node has a dual software bank update system. You can safely update the bank that is NOT active while the unit is online without disrupting programming, then choose a convenient time to switch to the new firmware. Software updates are always uploaded to the inactive bank.

  1. Using your web browser, navigate to the main web page of your MPX Node.
TIP - The IP Address of your MPX Node can be obtained by repeatedly tapping the upper user button on the front panel until the IP Address is displayed.
  1. Log in with your user name and password.
  2. From the left side menu, click on System Setup.
Picture of the main menu
  1. At the bottom of the System Setup page, click on the SELECT FILE button
  1. Using the dialog box that opens (this will differ depending on your operating system), browse for and select the file you previously downloaded.
  2. Click the UPLOAD button. A progress bar will show you the status of the upload. Once complete, the version number in the Firmware bank that is inactive will reflect the new version number.
  3. Click the Make Active link on the bank that contains the new version.
  1. A confirmation screen will prompt you to proceed with a reboot.
Note that activating new firmware requires restarting your unit. This will take about one minute, and will interrupt audio. Make sure your MPX Node is not on-air when changing firmware or rebooting the MPX Node.
