Data Entry Modes

20
Before you can use the keys on the front panel to enter ASCII
characters, the Omni 3200 must be in a mode that allows keyed data
entry. There are two terminal operating modes, each of which lets you
press keys to enter data under specific circumstances:
• Normal Mode. The terminal operating mode in which an
application program is present in the RAM and is currently
executing.
• System Mode. A special, password-controlled terminal operating
mode that is used to perform a variety of test and configuration
procedures.
When you connect an Omni 3200 terminal to a power source, the
application program stored in RAM starts executing and the terminal
automatically enters Normal Mode. The application then controls
how terminal keys, including the programmable function keys and
ATM-style keys, are used to process transactions and when you can
use specific keys to type characters or respond to prompts.
When you connect an Omni 3200 terminal to a power source which
does not yet have an application stored in RAM, the system message
DOWNLOAD NEEDED is displayed. At this point, you can proceed
to enter System Mode, configure the terminal as required, and
perform the required download.
To enter System Mode, you must press a special key combination and
then type in the required System Password. While in System Mode,
you can only use the 16-key core keypad to enter characters and to
respond to prompts. Key entries are controlled by the specific System
Mode function you select.
When an Omni 3200 terminal is running in Normal Mode, entering
System Mode stops the application. When you exit from System
Mode, the application is automatically re-started, Normal Mode is
entered, and data entry using the terminal keys is again controlled by
the application program.
