SECTION 8 - DISPLAY INTERFACE BOARD
The Display Interface Board is located on the Liquid
Crystal Display and is part of the microboard interface
to the Display. It permits the use of displays by differ-
ent manufacturers, by providing the microboard with
a means of automatically determining which Display
is present.
Since different display manufacturers require differ-
ent timing and control signals, the microboard Display
Controller must be configured to meet the requirements
of the actual display installed. When AC power is ap-
plied to the OptiView Control Center, the microboard
reads the panel identification (PID0 thru PID3) volt-
age levels on the display interface board during the
power-up sequence to determine which display is pres-
ent. These voltage levels indicate the actual display in-
stalled and the Display Controller is automatically con-
figured appropriately. To provide the appropriate Panel
ID voltage levels for the different displays, there are
different Display Interface Boards. These boards have
permanent wire jumpers that provide the voltage lev-
els to the microboard for Panel ID signals (PID0 thru
PID3). These jumpers connect these signals to either
ground or open-circuit. When connected to ground, the
voltage level for that signal is 0 VDC. When open, the
voltage level is the VCC logic level, which is either 3.3
VDC or 5.0 VDC, depending on the display (refer to
Microboard Program Jumper JP2).
The following are the different Display Interface
Boards and the Panel ID signals they provide to the
microboard.

The Displays can operate in either Normal or Reverse
Mode for the Right/Left (R/L) and Up/Down (U/D)
scan. Normal for the R/L scan is left to right. Normal
for the U/D scan is top to bottom. As used in the OptiV-
iew Control Center, it is configured to operate in Nor-
mal Mode for both of these scans. The Reverse Mode
for R/L is right to left. Reverse Mode for U/D is bottom
to top. The Display Interface Board provides the ap-
propriate signals to the display to put it in Normal Scan
Mode. By hard wired jumper or wiring configuration,
the signal is either tied to ground, VCC (+3.3 VDC or
+5 VDC, as determined by Microboard Program Jump-
er JP2) or left open as follows:
