This section contains overview information and procedures for
performing all available types of software and data transfers to
support Omni 3200 terminal installations.
What is a Download?
In a ‘download’ procedure, data is transferred from one system to
another. Usually, the system that sends the data is larger than the one
that receives the data. If a smaller system transfers data to a larger
system, or if the sending and receiving systems are of the same type
or size, the transfer is called an ‘upload’. In common usage, both
types of data transfer procedures are often called ‘downloads.’
To deploy and support the Omni 3200 terminal, two basic types of
data transfer operations are used:
• Data transfers (downloads) from a download computer, also
called a host computer, to an Omni 3200 terminal, and
• Data transfers (uploads) from one Omni 3200 terminal to another
Omni 3200 terminal.
Note: When processing transactions, the Omni 3200 terminal also
exchanges data in a packet-switching mode with a remote host
computer.
