CPU Card Software Download Procedures
5.7.2 XMODEM Protocol Binary Download
Follow the steps listed below to perform an XMODEM protocol bin download.
1. Set up a direct connection to the VT-100 craft port.
2. Locally connect the PC to the VT-100 craft port. Log into the system with the
Superuser
password.
3. Highlight the active CPU and press “
P
”.
4. The binary buffer area appears, and one of the buffers displays in an active state. The other
buffer may be empty or may have a file in it. Verify that the kernel version on the lower
half of this screen indicates
5.0.1
with a
checksum
of
0x12A459
.
5. If both buffers have files in them, highlight the buffer that is not active. Press the
Enter
key and four options appear at the bottom of the screen. Using the arrow keys, highlight
the
erase
parameter and press
Enter
. When the system finishes erasing the buffer it will
indicate an empty state.
6. Using the arrow keys, highlight the
empty buffer
area and press
Enter
. Four parameters
will appear on the screen. Using the arrow keys, select the
dnload
(download) parameter
and press
Enter
. Two parameters will appear at the bottom of the screen.
7. Using the arrow keys, select the
XMODEM
parameter and press
Enter
. The letter “
C
” will
begin duplicating across the screen. This is normal and does not indicate a problem.
8. At the HyperTerminal screen, select
file transfer
and send the file. Choose the appropriate
binary file to download using the
XMODEM1K
protocol to BIN buffer 1 or 2, depending
upon which bin is empty. The binary file being downloaded
must
match the BIN number
into which it is loading, and the binary file will be marked with either a 1 or a 2
accordingly.
9. Following completion of the download process, make the newly loaded bin active and
then erase the existing firmware from the now inactive bin. Perform the download process
again so that both buffers have the same firmware applied to them.
