The Y-Modem Flash Upgrade screen (Figure 39) 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.
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/additions and bug fixes. Figure
40 illustrates a Flash upgrade session in progress.
