Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Tycon Systems/TPDIN-Monitor-WEB3, Tycon Systems/TPDIN-Monitor-WEB3.
  2. 2Review the reported fix. Source-reported solution: Tycon Systems has released TPDIN-Monitor-WEB3 Firmware v2.4.2. Units already running v2.4.2, for subsequent updates (signed container):  https://firm.tyconsystems.com/tpdin-monitor-web3-v2/TPDIN-MONITOR-WEB3-V2_v2.4.2.tfw All units currently in the field, including the v2.2.9 covered by this report (legacy Intel HEX):  https://firm.tyconsystems.com/tpdin-monitor-web3-v2/TPDIN-MONITOR-WEB3-V2_v2.4.2T.hex A unit running v2.2.9 installs the .hex build directly and arrives at v2.4.2 in a single step; no intermediate version is required. The signed .tfw container cannot be read by a v2.2.9 updater, which accepts only Intel HEX, so the .hex artifact is the one every deployed unit needs.
