Contrast Adjustment
You can adjust the contrast on the ProMotion by pressing CTRL and F5 . There are sixteen
adjustments levels. Each key press combination will make the display darker until it reaches
the darkest maximum setting, in which case the next key press combination will result in the
lightest maximum setting. You can also adjust the contrast using the
View Angle (Contrast)
parameter or by Setting the Contrast Midpoint .
Operating Modes
The ProMotion has several operating modes. The default mode is Terminal mode. It allows
the ProMotion to display characters, respond to commands sent by a connecting device, and
send characters to the connecting device as keys are pressed. Other modes, described later in
this manual, enable you to
set operating parameters and program function key definitions
Host Control
The ProMotion’s design allows a connecting device (or “ host ”) to control its functions
through the transmission of a string of special characters.
Referred to as “ Escape commands ” (because each character string begins with the ASCII escape
character), these character strings enable the host to move the cursor to any position on the
display, clear selected regions of the display, sound a beep, alert or key click, program the
function keys and set any of the operating parameters.
The ProMotion has two sets of built-in Escape command modes, ANSI and Private. The set in
use is determined by the setting of the Escape Mode parameter.
When set to ANSI mode, the ProMotion recognizes a command set compatible with the
American National Standards Institute Standard X3.64.
When set to Private mode, the ProMotion recognizes a smaller, non-standard set of
commands.
The host can change the current Escape mode type at any time by issuing the corresponding
Escape command.
Information about using ANSI and Private Mode Escape commands appears later in this
manual.
