MODEL 2500 KEYPAD
The DANIEL INDUSTRIES MODEL 2500 INSTRUMENTATION SYSTEM
MICROCOMPUTER front panel has a 16-key keypad which gives the user the
ability to enter and change data and system commands. The keypad is located
approximately in the center of the panel, and is symmetrically arranged in four
columns of four keys each.
Ten of the 16 keys are marked with the numbers 0 through 9, arranged in
descending order. The remaining keys are marked with a decimal point, a minus
sign, an UP arrow, a DOWN arrow, and the command words of EXIT and ENTER.
The UP arrow, DOWN arrow, EXIT and ENTER keys have been assigned specific
functions. The keys and their functions are defined below:
UP/DOWN
Arrow Keys Sequences the front panel display forward or backward
through a menu or sub-menu. The display can be
changed one step at a time by depressing a key
repeatedly, or it can be sequenced rapidly by holding
down a key.
EXIT Key Moves the display to the next higher menu.
ENTER Key Selects the sub-menu displayed on the front panel, enters
the data that has been keyed-in on the display, and
initiates a printout of a report when the name of the
report is displayed on the front panel.
A further discussion of the keypad is provided later when operation of the
instrument is explained in greater detail.
