Total Access 3000 H2TU-C Flash Upgrade
Ability to download new firmware for the unit is available via the Total Access H2TU-C Flash
Image screen (Figure 48). This feature allows the download and installation of a firmware
upgrade. Any existing provisioning setting will be retained, while new provisioning items will
assume the factory default settings. Prior to installing, the H2TU-C will confirm that the
firmware is correct. When initiated, setup instructions will be displayed on the craft access
terminal.

The Download H2TU-C via Y-Modem menu (Figure 49) allows the user to initiate a Y-Modem
file transfer from the computer connected to the SCU craft access port to the H2TU-C. This file
is transferred to the SCU and downloaded to the H2TU-C at the SCU craft port baud rate;
therefore, a higher-speed connection to the SCU is recommended (typically 115200 baud) to
reduce file download times. At 115200 baud, a typical flash download to the H2TU-C will take
less than 3 minutes.
NOTE
The file downloaded to the H2TU-C via the SCU should be of the
“.bin” file type only and will be provided for feature enhancements
and additions.
