Omni 3200 Reference Manual

20 Data Entry Modes

Data Entry Modes

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 SRAM 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 SRAM 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 SRAM, the system prompt

is displayed. You can then proceed to enter

System Mode by pressing the [CLEAR] key, configure the terminal

as required, and perform the required download.

To enter System Mode after an application has been loaded into the

terminal memory, 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.
