Mercury 2+ Operator Terminal User Manual
Due to the limited amount of power available when using I.S.
equipment, the backlight control is automatic. The adaptive
control attempts to keep the backlight as bright as possible, and
will purposefully turn the backlight off and then back on again
whenever the beeper sounds, or a card is swiped.
This option also acts as a clear visual indicator that a key has been
pressed or a card has been swiped, and may be useful in noisy
environments when the beep itself may not be audible
Local Echo mode is a facility to help in checking that the
keyboard, barcode or card reader is functioning correctly. When
set, all key presses, readings or swipes echo the transmitted
characters to the screen. The characters are displayed in current
screen mode, and at current cursor coordinates, so the screen
display should be set to the appropriate mode before Local Echo is
set. Local Echo toggles on and off by pressing F1 (or START
BATCH 1 on the terminal automation keyboard), when in Setup.
In Local Echo mode, the terminal continues to communicate with
the host. Press ENTER to return to normal setup mode.
Pressing F6 (or START BATCH 6 on the terminal automation
Keyboard), while in the setup mode gives a single line display
showing the state of the digital inputs in real time. Press ENTER
to return to normal setup mode.
Pressing F3 (or START BATCH 3 on the terminal automation
Keyboard), while in setup mode, performs a display test. The
screen will turn all pixels on, then off, and the terminal will
automatically exit setup mode and return to normal operation.
