DISPLAY INTERFACE BOARD

(REFER TO FIG. 43)

The Display Interface Board is located on the Liquid Crystal Display mounting plate and is part of the Microboard interface to the Display. It permits the use of Displays by different manufacturers, by providing the Microboard with a means of automatically determining which Display is present.

Since different Display manufacturers require different timing and control signals, the Display Controller on the Microboard must be configured to meet the requirements of the actual Display installed. When AC power is applied to the OptiView Remote Control Center, as part of the power-up sequence, the Microboard reads the four Panel ID wire jumpers, PID0 through PID3, on the Display Interface Board to determine which Display is present. The configuration of these jumpers indicates the actual Display that is installed on the OptiView Remote Control Center door. The Display Controller on the Microboard is then configured appropriately.

On Sharp displays the configuration of wire jumpers P30 and P31 determines whether the Display scan orientation is Normal or Reverse (image reversal) scan. As described in the preceding “Display” description, Normal scan is left to right, beginning with the top row and continuing sequentially through the rows to the bottom row. Normal scan is used in OptiView Remote Control Center applications. In Display applications other than OptiView RCC applications, image reversal is sometimes required. In image reversal applications, the scan is reversed; the scan is right to left, beginning with the bottom row and proceeding to the top row. The jumper configurations determine the voltage level at Display Interface Board J1-30 (P30) and J1-31 (P31). If P30 is IN, the voltage at J1-30 is +5.0VDC or +3.3VDC (as determined by position of Microboard Program Jumper JP2); if OUT, 0VDC. If P31 is IN, the voltage at J1-31 is GND; if OUT, 0VDC. The Display reads these voltages and adopts a scan mode as follows:

SHARP LQ10D367 & LQ10D421 Displays:

SHARP displays require configuration of both jumpers to achieve total image reversal.

P30 IN - Normal scan; left to right OUT - Reverse scan: right to left

P31 IN - Normal scan; top to bottom

OUT - Reverse scan; bottom to top

The wire jumpers on this board are not field configu- rable, as with typical Program Jumpers. There are two variations of the Display Interface Board. Each board has the wire jumpers configured appropriately for the display to which it is attached, as shown below. Display Interface Boards are available individually for service replacement. The YORK part number of the Display Interface Board compatible with the installed Display is listed on a label attached to the Display mounting plate. However, service replacement Displays are provided as a kit (331-02053-000) that includes, among other items, the appropriate Display Interface Board for the Display included in the kit. Refer to explanation in “Liquid Crystal Display” description.

are simply passed through the Display Interface Board. The value of VCC is either +5VDC or +3.3VDC, as determined by the position of Program Jumper JP2 on the Microboard. PID0 through PID3, when installed, connect their respective Microboard (J5) inputs to GND; when removed, the Microboard pulls these signals up to +5VDC. When P30 is installed, the Display input (CN1-30) is connected to VCC (+5VDC or +3.3VDC as determined by Microboard Program Jumper JP2). When P31 is installed, the Display input (CN1-31) is connected to GND.
