The T9261-D supports USB2 and USB3 media devices. To upload the new firmware from a USB media device (thumb-drive), follow the steps below.

  1. Download the firmware to a disk and folder on your computer.
  2. Copy the firmware file from your computer’s disk and folder to the USB media device.
    1. There must ONLY be one copy of the firmware on the media device. Remove previous versions before inserting the media device into the T9261-D USB interface.
  3. Safely remove the media device from your PC.
  4. Insert the media device into the USB interface on the T9261-D.
  5. The fan and top blue LED will go off once the system mounts the media device and starts the upgrade script. The disk mount and script start takes about 10 seconds. The upgrade will take a little over a minute to complete. The device will reboot automatically.
  6. You can remove the USB media device from the T9261-D after the unit reboots and starts decoding.
  7. To confirm the update was successful:
    • Check the firmware version on the Web UI on the right side just above the tabs. The version should reflect the name of the firmware file loaded onto the USB media device.
    • Insert the USB media device into your PC and open the firmwareUpdate log.
  8. If more that one unit is upgraded using the same USB media device, there will be a firmware update log for each unit. The naming scheme for the firmware update log is as follows.
    • <SN>-firmwareUpdate.log

The Metadata tab displays available video programs and the audio PIDs for each.

The number of available audio groups that you can set depends on the number of available audio PIDs in the video program selected. For example, if the video program only has two audio PIDs you can set up to two audio groups. Click Edit Video to choose a different video program. To make changes to audio groups click the Edit Audio button on the Status sub tab.

This is a sample text. You can click on it to edit it inline or open the element options to access additional options for this element.

The available audio PIDs will be listed in this modal. PIDs need to be set consecutively and one PID cannot be set on multiple audios. Only the first audio group Format can be changed.
