This section presents procedures for back-to-back terminal downloads.
Hardware
Checklist
• The correct serial cable connects the RS-232 ports of the base stations of the
docked sending and receiving Omni 3600 terminals (refer to Connections for
Back-to-Back Downloads), or
• The MOD10 adapter and cable to connect the download computer serial port
(COM1 or COM2) directly between the two Omni 3600 terminals.
• Verify the RAM size on the receiving terminal is large enough to receive files
uploaded from the sending terminal. If the RAM on the sending terminal is 512
KB, the RAM on the receiving terminal must be at least 512 KB.
Software Checklist • The firmware version of the sending and receiving terminals must be identical
or very similar.
• One or more complete, authenticated, application programs are stored in
GIDs 1-15, RAM or flash, of the sending terminal. In this type of operation, all
files stored in application memory of the sending terminal download to the
receiving terminal.
• Before you initiate the download procedure, remember to select Group 1 as
the target file group on both the sending and receiving terminals. The required
system mode and file group passwords must also be available to make the
required system mode menu selections on both terminals.
• The current CONFIG.SYS variables, date and time, and other terminal
configuration settings on the sending terminal are those downloaded to the
receiving terminal. Ensure your desired settings.
• All signature files required to authenticate the application files being
downloaded to the receiving terminal are present in the RAM or flash file
system of the sending terminal.
• The certificate tree of the sending and receiving terminal 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 terminals.
• If application files are downloaded to the receiving terminal in previous
operations, use system mode menu options to clear the RAM and flash file
systems of the receiving terminal before you initiate the back-to-back
download procedure. This ensures a clean download.
