Programmable Features
Two data parallel input mode is selected when bridge DCON on the ECA is
open (see fig. 2). In default configuration the DCON bridge is set. See page 9
for more details.
The method of gray scale coding can be selected either with COLMAP control
input (J1/27) (see Signal Inputs on page 5) or with solderable bridge MAP on
the ECA (see fig. 2). If COLMAP is left disconnected, MAP brigde defines the
mode. If MAP is left open (default), colour mapping is selected. If MAP is
bridged, binary coding is the method. Note that if COLMAP control input is
used MAP has to be open. See page 8 for more details on colour mapping.
Notice: Only binary coding of input data can be used with Two Data Parallel
mode. See Gray Shades and Two Data Parallel Mode in page 9.
For compatibility to previous versions of A series displays the horizontal and
vertical positioning of the image can be adjusted with solderable bridges on
the ECA of the display. VERPOS0–VERPOS2 (MSB) are for vertical positioning
and HORPOS0–HORPOS3 (MSB) are for horizontal positioning (see Fig. 2). Both
settings form a binary number where a set bridge is a "0" and open bridge a
"1". The adjustment range for VERPOS is 0 to 7 upwards (default 000 for no
shift) and HORPOS 7 right (0000) to 8 left (1111) (default 0111 for no shift).
Notice: Due to the fact that picture positioning is not supported by Planar
multi-colour VGA displays and may not be supported by some future Planar
VGA displays, the use of this feature should be avoided.

Note: Absolute maximum ratings are those values beyond which damage to
the device may occur. The minimum and maximum specifications in this
Operations Manual should be met, without exception, to ensure the long-
term reliability of the display. Planar does not recommend operation of the
display outside these specifications.
