3.5 About the QWERTY Keypad
The QWERTY touch keypad of ES601-US is used for entering system settings, equipment information,
control numbers, comments and test data. An example of the QWERTY keypad is shown in
Figure 8 , for
entering the ES601 I.D. of System Settings Menu #3.
When the QWERTY keypad is activated on the display, ES601-US will also optionally accept character data
from ES601-US Barcode Reader Port or from the PS/2 Keyboard / Barcode Port. When activity is sensed
from any one of these input devices, the other two are disabled until the next time the QWERTY keypad is
displayed.
ES601-US reacts differently to data arriving via the Barcode Reader Port, compared to data from a PS/2
keyboard. For data received via the Barcode Port, ES601-US will wait until a complete string of characters,
terminated by carriage return, is received. After sensing a carriage return, ES601-US removes the QWERTY
keypad from the LCD display, and shows the Barcode data on the LCD along with
ENTER
and
CANCEL
buttons, allowing the user to accept or reject the received data.
For the case of data received via the PS/2 Keyboard Port, ES601-US displays each character as it is received
from the external keyboard. In this case, characters typed on the external keyboard simply appear at the top
of the QWERTY display until a carriage return is sensed.
