This section provides the hardware and software checklist needed for back-to-
back application downloads. The procedure for back-to-back device downloads is
also discussed.
The correct serial cable connects the RS-232 serial ports of the sending and
x
receiving V 810 devices (refer to
Downloads).
Verify that the SRAM size on the receiving device is large enough to receive files
uploaded from the sending device. If the SRAM on the sending device is 512 KB,
the SRAM on the receiving device must be at least 512 KB.
The firmware versions of the sending and receiving devices must be identical or
very similar.
One or more complete and authenticated applications are stored in the GIDs 1
SRAM or flash ROM of the sending device. In this type of operation, all files stored
in application memory of the sending device download to the receiving device.
Before initiating the download procedure, remember to select Group 1 as the
target file group on both the sending and receiving devices. The required system
mode and file group passwords must also be available to make the required
system mode menu selections on both devices.
The current CONFIG.SYS variables, date and time, and other device configuration
settings on the sending device are those downloaded onto the receiving device.
Ensure that the desired settings are correct.
All signature files required to authenticate the application files being downloaded
onto the receiving device are present in the SRAM or flash ROM file system of the
sending device.
The certificate tree of the sending and receiving device must be synchronized.
That is, there can be no more than one revision difference between the certificate
data currently stored in the memory of the sending and receiving devices.
If application files are downloaded onto the receiving device in previous
operations, use the system mode menu options to clear the SRAM and flash ROM
file systems of the receiving device before you initiate the back-to-back download
procedure. This ensures a clean download.
A back-to-back application download overwrites existing applications, libraries, or
any other files stored in the SRAM of the receiving device.
All CONFIG.SYS records and settings on the receiving device – protected and
non-protected – are replaced by those of the sending device. Ensure that these
records and settings on the sending device are correct before initiating the
download.
Passwords on the receiving device are retained.
Certificates and signature files downloaded onto the receiving device, together
with application files, must be processed by the file authentication module on the
receiving device on device restart after the back-to-back download completes.
